Rectification tower is undertaking quality and quantity of heat are exchanged, in the process that realizes corporeal depart, rectify, extraction, having a lot of parameter is need pilot, otherwise the rectification quality of unavailable also beautiful. Be pressed from the tower first and the tower is lukewarm the control program of this respect begins to introduce, hope everybody can master.

The tower approachs one of main control target that are rectification tower, our purpose is have inside the limits that controls tower pressing in the regulation, once its wave motion crosses old saying, the stock in whole equipment balances amiable fluid balance to be able to be destroyed, affect the quality of the product thereby. Adjusting when rectification tower tower is pressed, want to just be done according to actual condition, the condenser e.g. cat head is segregate implement when, can collect a quantity adjustment pressure through gas phase, general tower presses what can collect an amount as gas phase to increase and drop. But if condenser is to coagulate completely implement below the circumstance, adjust means has differred, the volume that need adjustment cryogen measures will realize the control of pressure. In other condition changeless circumstance falls, proper addition is cold dosage can be tower pressing reduce. Two kinds of circumstances of above introduction explain in the light of pressurization tower, if be of atmospheric tower,the word still must make an analysis additionally. Again for the tower that says rectification is lukewarm, its main payoff is tower pressing and stock, it is to use those who change evaporator to heat normally vapour quantity goes to thermoregulation whack. When when equipment medium temperature is worth under the regulation, need to increase vapour dosage only, can be the content that cent recombines in rectification tower increase, make temperature elevatory thereby; And when temperature prep above provides a value, need to reduce vapour dosage only, can have adverse effect.
