Evaporation in the Oil and Gas Industry

Evaporation, or distillation, is a separation process that takes advantage of the changing physical states of water, or other solvents, from liquid to vapor. It is unique from other separation processes, in that the water is removed from the contaminants rather than the pollutants being filtered from the water…

PRAB Mechanical Vapor Recompression EvaporatorMechanical Vapor Recompression Evaporator

The low electrical energy consumption of MVR evaporators allows treatment on medium to high flow wastewater treatment applications (2,600-53,000 gal/day) where excess or waste hot water/steam and cooling water is not available.

PRAB EW Series Hot/Cold Water EvaporatorHot/Cold Water Evaporator

Hot/cold water evaporators enable the use of low or no cost energy sources – excess hot water or steam that is already available from cogeneration or cooling plants. Using existing waste heat to power the evaporation process reduces operational costs to only the power needed to run the recirculating pumps and/or scraper.

PRAB Heat Pump EvaporatorHeat Pump Evaporator

The heat pump vacuum evaporator offers reduced electrical energy consumption, and superior reliability for low to medium flow produced water treatment applications (40-12,680 gal/day). Evaporation occurs under high vacuum conditions, of 4 kPa absolute pressure, lowering the boiling point of water to a temperature of approximately 30°C.
