In cosmetics, the most common use of acetone is in nail polish remover. Acetone is a colorless, flammable liquid that evaporates easily. It is an organic compound because carbon atoms are present in acetone's chemical formula, which is (CH3)2O.
Swenson thermal vapor recompression (TVR) evaporators use a thermocompressor to reduce the steam required per pound of evaporation. To reduce energy consumption, water vapor from an evaporator is entrained and compressed with high pressure steam in a thermocompressor so it can be condensed in the evaporator heat exchanger. The resultant pressure is intermediate to that of the motive steam and the water vapor.
It's a popular misconception that a TXV regulates the evaporator to a specific temperature; actually it tries to get the evaporator as cold as practical given the low side pressure. You can use the same TXV for an air conditioner or a deep freezer, until the limits of the refrigerant itself are reached.
