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.
Short-tube vertical evaporators The short-tube, or calandria, vertical evaporator (Figure 3) isone of the earliest types still in widespread commercial use (3). The short-tube evaporator is characterized by tubesheets (A)extending across the body and a central downspout (B).orizontal tube evaporators The horizontal tube evaporator (Figure 2) is the oldest typeof chemical evaporator, although other improved types arenow more commonly used.The horizontal tube evaporator is the only type of chemicalevaporator in which the heating medium is inside the tubes.
