Solvent Drying
​
This market includes the drying of solvents used for cleaning and/or purification of a material. This type of drying is found in chemical plants, refineries, manufacturing plants, etc. where a material is rinsed by a hydrocarbon stream, then recycled, dried, and returned to cleanse the material. For example, an acetone liquid stream is used to wash a thread used for making tea bags. The dirty acetone leaves the washing tank and enters a carbon purification system. It then enters a distillation column. The column vaporizes the acetone, leaving most of the contaminants. Out of this system, the acetone contains about 2% water. The acetone is dried in a Lectrodryer adsorption system and returned to the washing tank.
