Ethane is most efficiently separated from methane by liquefying it at cryogenic temperatures. The gases produced also cause natural liquids and liquefying tissues to become frothy. Conceptually, LACE works by compressing and then quickly liquefying the air. A blender is a kitchen appliance for chopping or liquefying food. Thilorier's original apparatus for liquefying carbon dioxide used tanks made of cast iron. This brought him to the work of liquefying the various gases. There are two processes for liquefying natural gas in large quantities. The liquefying equipment would be distributed by Steiner-Prematechnik-Gastec.
