Hazardous waste disposal.

Contaminated glycol is refined by vacuum distillation. Specifically the evaporator is heated to a temperature below the degradation temperature of the glycol. The vacuum is used to bring the flashpoint down sufficiently so that glycol evaporates or flashes at that temperature. The glycol is condensed and filtered through activated granular carbon. The principal use of refining the glycol is to refine the triethylene glycol used in natural gas dehydration plants. For such purposes the equipment is mounted upon a trailer to be taken to the plant for cleaning glycol. In such instance, in addition to refining the glycol, a cleaning agent (which contains a degreaser) is added to the refined glycol. The glycol is refined while the natural gas dehydration plant is in normal operation and therefore it is not necessary to stop the natural gas dehydration plant for refining the glycol used therein. In addition, by the addition of the cleaning agent, the dehydrating plant equipment may be cleansed of hazardous waste. The hazardous waste will be separated and concentrated in the distillation. Therefore, the transportation of the hazardous waste to a disposal location is simplified.
