Abstract
The present invention relates to a process for controlling the antifoam injection based on the pressure differential of the column. More specifically, the present invention relates to a process for controlling the antifoam injection based on the pressure differential of an aromatics extraction unit using an intelligent differential pressure transmitter. The controller communicates with the antifoam injection system so that the antifoam is injected to the unit only when it is required.
