Hi Ant, hope you're keeping well.
That's a very good question - one I've not considered. I believe it drops all the glycerol, but I've not made a measure of residual glycerol after distilling off the methanol. There may well be some, but I don't know for sure.
One way to tell.... I'll let you know, with as precise an experiment as I can muster.

I have been experimenting with methanol recovery and filtering (in an attempt to dispense with the need to water-wash), but I have not had any appreciable amount of "soap" appear in my filter. I have been scared to use the bio without washing, because of this. It does seem to be a little more emulsion resistant, though.
I use KOH. Is this the reason for the missing soap?

Hi Chris
KOH soap seems to slip thru filters easier than NaOH soap. It needs to be filtered gently.
Are you pumping biodiesel thru the filter, or letting it gravity strain?
KOH soap seems to form a fairly thin gel, and if you put enough pressure into your filter, you can find the soap gets squeezed through.
Perhaps try less pressure on the soap filter, and filter at as low a temperature as possible so it is not as soft.
Magnesol seems to successful in removing KOH soap.
I prefer to use NaOH because it can be filtered easier, and tends to drop soap to the bottom of the tank under gravity, so I don't even filter the top volume after it's settled a few days.
Bromophenol titration can tell you if the biodiesel is sufficiently soap free. It it a very useful titration indded.
Hope that helps, let us know how you get on with gentler filtering at lower temperature.

.....so KOH soap = dawn dish detergent
...and NaOH soap = cascade dishwasher detergent
(I dont know if these are common brands in the UK, but I thought it was a great analogy!)
And, yes, I have been filtering at high temp and pressure. No wonder!

Hi Graham and other smarter folks than I!
Some of your technical expertise please?! My first attempt at a home-made venturi was less than successful. Instead of 'sucking' my venturi was 'blowing'. I tried it in both directions. My thoughts on this were my smaller side port had extended into the stream and should probably be pulled back and/or a smaller side port.
I was attempting to pound a 3/4" copper pipe down to 1/2" and my side port was 1/2".
Hi Fatkid
If you look down the tube you are blowing into, you shouldn't be able to see the side port. It should just look like a nice round hole.
If that fluid going down the tube can 'see' the side port before it gets there, it will head for it and go down it.
You need a shape something like this ...
The main flow goes in the left side, out the right side.
The suction port is at the bottom.
I placed the hole just where the tube sarts getting wider - JUUUUUST after the narrowest part.
It is a hole in the side, nothing is poking into the flow - like I say, surprise the flow, it shouldn't even know there's a side port till it gets there.
If you do it just before the narrowest part (too far to the left) it won't work well.
Hope that makes sense.This message has been edited. Last edited by: GrahamLaming,

Hi, I've made and tested my own venturi to the suggested design but with a small difference. It has 8 x 3mm holes around the throat which is 13mm and a jacket with a single 5/16 feed. the suction is incredible, haven't tried total lift yet but I expect 10 ft plus. See photo

Couldn't do it in one so here's another, by the way the mixers are made from a single piece of tube.

Hi jamesrl;
[QUOTE]Originally posted by jamesrl:

You wouldn't be able to have any pics of this thing disassembled would you?
Thanks, for the 'SCHHLUUUURPPPP' that was a good chuckle. I definitely had that designed wrong, so it needs to 'sneak' up on the port. Is your copper pipe there in the UK softer than on this side of the pond, I had a dickens of a time trying to form it?
Thanks for all of your tinkering.
jamesrl.. a couple of comments .. I'm sure you mean a 8 mm hole? Does the tapered feed tube end at the larger tube or extend slightly into it?? It looks to me like more vacuum would be produced if you moved your feed tube closer to the end of the narrowd tube and angled your feed tube about 60 degrees instead of 90 degrees .. just my two bits worth...
Hi Jamesrl
Really neat! Which parts did you use for the jacket - that's exactly what I'd like to try.
How did you crimp the pipe in your mixer?
Hi fatkid,
The pipe here is pretty hard - there are several things to prepare yourself for when doing this ...
1. Be patient. The shape seems to take forever to start, but it does form faster as you progress - as the tube narrows, each hit has more effect.
2. Be gentle. Don't try and create a venturi shape in 10 enormous hits! Many medium force hits, where you can barely see the indent you've made, will ensure the shape develops evenly and without too much stress to your arm.
3. Concentrate on forming the narrowest part first, angling the tube against the anvil as in my video, and the shape will naturally form a venturi with one sharp taper, one smooth.
Hi Onaday,
I think jamesrl has 8x 3mm diameter holes around the neck of the tube.
Hope that helps,

Hi all,
Fisrt things fisrt, to make it clear, around the throat just and only just on the outlet side (long taper) there are 8 eqally spaced 3mm or 1/8 holes. The first attempt had 12 x 2mm, that worked well also.
For all those wishing to make a venturi, heat area to be worked to bright red with blow lamp, when that has been done quench in cold water this will soften the copper, it's called annealing, work the tube it will form very easily so be gentle with the blows. As you work the copper will get harder again, thats work hardening, so soften it again and carry on working. You can keep annealing as often as you wish but remember that if you anneal close to the finished shape the tube will be very soft.
Graham to answer your question, the jacket is made from an end feed 22mm coupling slide over the venturi and shaped in position. The inlet tube was fitted first using copper to copper brazing rods and drilled through after attachment. I hope that makes it clear.
Got to go now but back later with info on mixersThis message has been edited. Last edited by: jamesrl,
I've seen several venturi suction pumps and air amplifyers that were designed like this. has anyone tried it? I think the key to this is if you have flow through the system then it should never backup and push down the suction hole. it would probably be best installed with the outlet pointing down into your processor so unless you overfill the processor it should never go back down the suction tube.
for some reason my picture is not posting correctly when I looked at it. the inlet should have a tube moving completely past the suction port. for some reason the line on the bottom does not show up when I opened it.
now it's showing correctly

Just letting you guys know that know that a venturi pump can significantly reduce your pump flow rate because of the backpressure it creates.
This is due to the reduction of the pipe diameter in the throat (nozzle)
Wouldn't it be possible to plump the suction from the venturi to the base of the methanol condensate tank to collect and mix back in methanol while processing. This system would then be come a reflux (or some thing to that name) reactor and you can process at higher temperatures or possible use even less methanol
By using a diverter valve system you could change the suction between the top or bottom of the tank depending of where you want to remove methanol of mix it back in.
"Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning."
Hi Cover,
That's a very interesting suggestion - thanks.
I've not tried processing above 60C, so don't get much condensate during the period, but it would be interesting to see how the process time is affected by running say at 65C and returning condensate.
I have a sneaking feeling may not be feasible to go much hotter than that, because the vapourisation of the methanol will tend to keep the temperature down.
Here's an analogy...
Imagine trying to boil a kettle of water, and you want to get the temperature above boiling point - it's just not going to happen - unless you pressurise the system.
I would be very reluctant to pressurise my system, as it is not rated for running at more than a few psi.
There may also be an efficieny tradeoff, as you'd need to keep condensing vapour, and your condenser may lose heat energy to the environment.
The venturi should be fairly free flowing if well made, because although there is a restriction, is is not impeding flow by much at all whilst not pumping, and even when it is pumping, we are moving fairly low flow-rates.
I have hydrostatic indicators (manometers) on the test system, so I can see backpressure and so on.
Sounds wrong, you'd expect a narrowing from 22mm to 8mm to have an eneormous effect, but here's why it is less than you'd expect ...
We are not really blocking the pipe, we are gradually encouraging the flow to speed up in one section, and gradually then slowing it down.
'Gradually' is important - the tapers control the gradual acceleration and deceleration.
So the flow rate is not affected nearly as much as if we had a classical sudden restriction in the pipe, like from a valve.
A really good venturi mat reduce flow rate by only 10% or so.
The back pressure does increase when the venturi is sucking a flow of liquid or gas into it, but this is only during dosing and dewatering and distilling, and we can turn the suction flow rate down to quite low levels during these processes. The back pressure reduces as you reduce the speed of drawn-in material.

Congratulations on a very tidy job - I wish I had the knack. My kitchen table is covered in the world's supply of reducers, T pieces and various offcuts of pipe as I try to figure a way to make a venturi without recourse to "copper bashing"

Your are so right Graham
It wouldn't make much sense to go over the boiling point of methanol if your not working with a presured reactor and the whole ventur setup wouldn't be need as it would be a closed system.
But there will always be vapour that can be reclaimed even at 65C. So if there is no point on going higher temps, there is always the possibility of using less methanol.
"Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning."
Hi everyone. Been a long time lurker and have built my equipment (processor built like Graham's)but have not actually used it yet. I have been doing small batches. I am reading it right that you have done your 3/27 test before settling as stated in your writeup? I see others doing the test after settling. Please clarify.

The Disney theme parks will let their male employees look a little more like one of Snow White's seven dwarves — at least when it comes to facial hair.
According to the Orlando Sentinel, the Walt Disney Co. announced that male employees will be allowed to sport beards and goatees after a 60 year ban.
The new policy, which takes effect Feb. 3, eliminates a facial-hair ban that has for decades been a source of grumbling among some of the company's male theme-park workers.
Disney's new policy restricts any facial hair to no more than a quarter of an inch in length. And the company says any chin whiskers "must create an overall neat, polished and professional look" and must be fully grown in and well-groomed.
The reversal comes 12 years after the Magical Kingdom first allowed male workers to have mustaches, a decision made in 2000.

Before this weekend's series at Fenway Park, the last time the Cubs appeared in a game that mattered there was 1918. It was the World Series and as the result of a shortened season due to the world being at war, the two teams at the top of their divisions were selected to play for the championship.
Those teams were of course, the Boston Red Sox and the Chicago Cubs.
1918 is a Series that ended up in the W column for the team from Beantown. That year would haunt them for 86 years until their next championship. Yankees fans would chant NINE-TEEN EIGHT-TEEN at the Red Sox year after year as they would meet their AL East division rivals in the playoffs in what felt like every single year (although realistically that was not the case). The Cubs on the other hand, are still waiting to capture their 'next' title and the last one occurred 10 years before the 1918 Series. In a decade that featured arguably the best Cubs teams of all-time, they would unfortunately come up short (possibly to their own accord, according to documents recently released) and the memories they would have of Fenway Park were not exactly fond ones.
93 years later, a Cubs team would finally step back into Fenway Park for games that counted. Not playoff games mind you (although I do predict that's how 2011 will play out). A weekend series that has the entire MLB fan base watching primetime matchups between two of the most storied franchises in the game. It's definitely a series I've kept my eye on since the schedule was released and I was // this close to heading to Boston this weekend to take a game or to in, in person. As it is, while Wrigley Field is the best place to watch a baseball game, arguably, Fenway Park is the second best (and some fans would even flip flop those two). The two oldest ballparks in the major leagues, it's amazing how high they rank in the eyes of baseball fans. The casual fan would think that the newer parks featuring all kinds of replica throwback feel plus the technology and comfort of modern day would be the favorites of fans. However, as it turns out, while some of the newer amenities are nice, the replica throwback effort often comes across as trying too hard and nothing can match the true feeling you get when you walk into the real deal.
Wrigley Field and Fenway Park, while receiving slight updates and additional seats over the years since the 1918 match up, are still the truth when it comes to our favorite past time. They provide fans with a home to celebrate their team game in and game out and the opportunity to relish in the history of their beloved franchises as it surrounds them inside the ballpark every where you look. There is no need to reference a key part of the stadium or the field where something amazing or magnificent happened throughout the years. No need for pictures or museums. Whatever is there to celebrate the past is simply by choice, not be necessity. All of the areas of the ballparks where those special moments occurred are still there, right in front of you, getting groomed and prepped by the grounds crews each and every season.
The two parks are special in that way and nothing else in the league is, can or will ever be quite as magical as them.
The 1918 Series is something the two teams have in common. The fact that their ballparks are such true relics to the history of the game is certainly another.
I was sent a review copy of a book called 'Remembering Fenway Park – An oral and Narrative History of the Home of the Boston Red Sox'. It's a great book and I wish they did one for Wrigley Field.
My favorite thing about the book is the way it manages to cover the history of the park from both the inside and out. What I mean by that is, not the outer walls and inside of the park, but the way it reviews the history of the stadium as an observer in addition to the quote, emotions, memories and thoughts shared by former Red Sox players who played many, many games at Fenway. With a foreword by Johnny Pesky, immediately you are taken to a place that gives instant credibility to the author. The stories told by the players give you an inside look as to what it is to be a Boston Red Sox player and the images that accompany it are spectacular.
Williams, Fisk, Ramirez, Rice, Clemens…they are all here. The book takes you decade by decade, year by year breaking down what the atmosphere was like around Boston at the time. It paints a picture as to what the pulse of the nation felt like and how it affected the league as time went by. It's hilarious to see the old park in it's youth and the types of ads that are around the stadium (apparently shaving blades were a very hot commodity in the early 1900's and the companies that made them were willing to shell out dough to get their razor known around Fenway…also a razor with two blades was a big deal back then…what are we up to, like seven blades by now?)
Some of my favorite images are those of the spectators. I wonder if we'll ever get back to wearing suits and fedoras to the ballpark. They say what's old will be back and become new again.
To see Fenway Park expand throughout the book is also a very interesting aspect. It is like a time capsule reference of the business plan blueprint the organization took throughout the years. How to make more money…where to put more seats…how to get more people to the ballpark. Baseball is a beautiful game with it's measurements from mound to plate and from base to base. However, while the talent on the field is a spectacle to behold, the game is also a business. The owners of the team throughout the years clearly understood this and it's fascinating to see them maintain the honor and reputation of the park as a landmark of the sport while still finding places to build here and change there to increase the seating capacity. If they had made mistakes or errors along the way, they'd still be selling out to large numbers, however, fans wouldn't feel the same way they do about the ballpark.
Opening Day line ups of the teams throughout the years from 1912-2009 is also a great resource in watching the team develop like an amoeba. Young stars come up to the league early in the book and you watch their careers develop until they leave you as a respected, beloved veteran at the end of their careers. This happens constantly and it is also an interesting way to see how the Red Sox have handled the ballclub throughout the years. Who did they keep? Who did they trade? Who did they sign? It's a record of nearly 100 years of business decisions that have made the Red Sox the team they are today and Fenway Park the stadium we all know and respect.
Wrigley Field deserves this type of treatment. I know that there are NUMEROUS books out there about the history of Wrigley Field and many of them are quite good. However, aside from no World Series title reference next to the year 1918 in the book and the dates listed as 1912-2010 (which I feel gives the impression that Fenway closed in 2010…I maybe would have listed it as 'Since 1912' or something to that effect), the author, Harvey Frommer, does it right. If he already has encapsulated the history of Wrigley Field, then I want someone to tell me where I can get it. If he hasn't, then let this be my official ask that he do so.
Baseball fans will love this book even if they are not Red Sox fans. I would encourage you to find it, buy it and enjoy.
Rubber band match tonight. Cubs at Red Sox. One more game that matters in the books for 2011 at Fenway Park tonight on Sunday Night Baseball. Garza is out with tightness in his shoulder. Byrd still hospitalized from being hit in the face with an Acevedes pitch. While my thoughts are with Byrd and I hope for GREAT news as far as he's concerned and I wish Garza could represent us in this third game against the Sox, it will be fun to see one more game against the Sox at Fenway……and I hope we get seven more this post-season. Only this time, I want the Cubs to walk away with the title and I want to be there. That's how I'd like to remember Fenway Park.
Go Cubs Go!

Welcome everyone! This is LEIPE site and was made for introducing and sharing indie music especially from LEIPE. Take your time and enjoy your visit here. Many thanks !
When I was a kid I always dreamt that one day I could be a rock star but I didn't know how to do that because I thought I didn't have enough skill :)
In the early 1990, when I was in senior high school, one of my school friends told me that his band, Tintin Band, needed a vocalist. Then I took his offer. Once in our school's bazaar, we covered Metalicca's songs, Master of Puppets and Motorbreath. I thought we performed well there. Another day I performed as vocalist for another school friend's band, Mek Goler. But I didn't go too far. As a student I begun to think about going university.
When I was studying in university, sometimes my old dream was teasing me. Then with my friends, I formed a band and performed on some campus' sessions. But we just played for fun there. We preffered studying university than going to be professional musicians. Sometimes I thought I'd would rather go solo but I realized I didn't have enough skill..hahahaha..
In those years I wrote many songs. I recorded those songs for self collections.
In the end of 1990's, I graduated from university. And so that my old dreaming was blown away. I begun to think of having a job and I thought that music was not my really job..so desperated?..hahahaha..
In 2000's, I've been working in a government office untill now. It was getting busy. So then my old dreaming's totally disappeared as I'm getting married and having kids and I've been thinking that I was too old to be a rock star..hahahaha..
In 2010, I was 37 years old. Finding and reading some music's articles on internet, this old dreamer has found and learnt how to make digital musics. I begun recomposing my songs. Not to raise an old dreaming as a rock star..hahahaha..I think it's enough to be a songwriter. It's worth enough for sharing my dream and my music to the world !

PBR 1940s weekend 2012
July 7/8 and the Pontypool and Blaenavon Railway's 3rd 1940's weekend, and what a brilliant weekend. A thoroughly good time was had by everyone, and whilst it was rather damp on the Saturday the sunny warm Sunday more than compensated for it. A big thank you to everyone for making it the event it was - here's to next years.Read More
