Water stripping tower of extraction unit
Thread Content
In the water stripping tower, the stripping steam enters the recovery tower; however, it seems that the amount of this stripping steam is unstable and fluctuates constantly, with the negative pressure at the top of the tower also varying. How can the amount of stripping steam be stabilized? How is the amount of hydrocarbon vapor at the top of the water stripping tower controlled?
Use a control valve to regulate the flow, or a flow-limiting orifice plate.
Our recovery tower operates under slightly positive pressure; the amount of stripping gas fed into the tower is controlled by regulating the pressure of that stripping gas, with relatively small fluctuations in its volume
