Abstract
In a batch process in which reaction effluent is dumped from the reactor to a flash tank through a dump line which contains both a dump valve and a control valve, the control valve is manipulated in response to a signal which opens the control valve at a desired rate as a function of time or in response to a signal which is representative of the maximum opening of the control valve which can be maintained without exceeding a pressure limit in the flash tank whichever signal is representative of the lower opening of the control valve. In this manner, reaction effluent is withdrawn from the reactor at a substantially maximum rate without causing flashing across the dump valve and without exceeding a pressure limitation for the flash tank.
