摘要： The reflux rate of the overhead product from a tower and the reboiler temperature are automatically controlled utilizing the equations hereinafter mentioned. The control system includes sensors sensing the temperatures of the overhead product leaving the tower, of a portion of the overhead product being returned to the tower, and of the bottoms product leaving the tower. The flow rates of the feedstock and the portion of overhead product being returned to the tower are also sensed. A control system then calculates a desired reflux rate and reboiler temperature based on the sensed parameters and a current cycle of operations and a next previous cycle of operation. The control system stores all current data so that the data may be used in a subsequent cycle of operation as the next previous cycle information.

摘要： In a fractional distillation tower which is divided into a plurality of sections by total drawoff trays, and wherein at least one fraction is withdrawn from each section. The cut point temperature between fractions is determined based on the partial pressure and temperature of the vapor in the upper portion of a section. The thus determined cut point temperature may be compared to a set point with the results of the comparison being utilized to maintain the actual cut point temperature between fractions substantially equal to the desired cut point temperature.

摘要： In a fractionation distillation process in which a pump around stream and an external reflux are utilized to control heat removal from an upper portion of the fractional distillation column and in which the pump around stream is utilized to preheat the feed stream flowing to the fractional distillation, the flow rate of the pump around stream is manipulated so as to substantially maximize the flow rate of the pump around stream while maintaining a desired heat removal from the fractional distillation column. Priority control of the pump around stream and external reflux result in a maximum preheating of the feed stream flowing to the fractional distillation column which improves the energy efficiency of the fractional distillation process.
