Abstract
PURPOSE: To speed up response, shorten the time of settling, and improve the efficiency of energy by converting tower temperature near pinch point and energy supplied to reboiler into control signals for regulating the amount of raw material to be fed.
CONSTITUTION: As control factor for the amount of raw material to be fed, the temperature of tower near pinch point and the amount of energy to be supplied to reboiler; that is, the concentration operating line and the recovery operating line are stabilized by the measured value of the temperature of the tower near the pinch point, the gas flow rate in the concentration portion is stabilized by the measured value of the amount of energy supplied to reboiler, and the overall balance is controlled by a combination of the foresaid temperature and energy amount. For example, the temperature detected at the point A near pinch point is setn to the controller 24 by the signal line a, and according to a result of a combinating calculation with the aount of steam supplied to the reboiler 19, the raw material feed valve 21 is regulated by a direction from the controller 24 to regulated the amount of raw material to be fed and the temperature of still is corrected.
