In an oil and gas production, flash-gas is a spontaneous vapor that is produced from the heating or depressurization of the extracted oil mixture during different phases of production. [1] Flash evaporation , or flashing, is the process of volatile components suddenly vaporizing from their liquid state.
One key feature when preventing flash-gas is the diameter of the piping. If the pipes are too thin and long, loss of pressure and friction tend to occur. If the evaporator is too high above the receiver, the rising pipes produce a small amount of vacuum at the topmost portion, making the fluid to undergo ebullition and produce flash-gas. On the ...
A vapor–liquid separator may also be referred to as a flash drum, breakpot, knock-out drum or knock-out pot, compressor suction drum, suction scrubber or compressor inlet drum, or vent scrubber. When used to remove suspended water droplets from streams of air, it is often called a demister.
The flash gas that is produced in this tank leaves the liquid line and goes to the economizer entrance of the screw compressor. [ 5 ] Refrigeration cycle optimizers such as EcoPac's E-Series, keep the original design of the refrigeration cycle without modification.
A representative pressure–volume diagram for a refrigeration cycle. Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), [1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles.
The reduction in pressure across the control valve causes the condensate to undergo a partial vaporization referred to as flash vaporization. The raw natural gas from the low pressure separator is sent to a "booster" compressor that raises the gas pressure and sends it through a cooler, and then to the main gas compressor.

In chemical engineering, the Souders–Brown equation (named after Mott Souders and George Granger Brown [1] [2]) has been a tool for obtaining the maximum allowable vapor velocity in vapor–liquid separation vessels (variously called flash drums, knockout drums, knockout pots, compressor suction drums and compressor inlet drums).
