Mar 28, 2011  For a vertical Flash Drum the surge time is in the range of 4 to 7 min and that for a horizontal vessel, it ranges between 7 to 12 min. Flash Drum used in Cativa Process has a surge time of 5 min. So multiplying this time with the liquid volumetric flow rate, we get the liquid volume held in the flash drum.

Flash Distillation - Lecture Notes on Unit Operations

Flash distillation is used to separate components in a mixture making use of the difference in their volatilities. The operation consists of partially vaporizing or condensing the mixture by either heating or cooling the feed and separating the vapor from the liquid in a tank, called a flash drum (see Fig. 1) Figure 1. Flash drum

Foam control in crude units - DigitalRefining

Preflash drums are used in crude units to “flash off” light boiling range hydrocarbons from the crude oil so that vaporisation is minimised or eliminated in the hot end of the exchanger train. In the back end of the hot exchanger train the temperature is high and pressure is reduced.
