Rectification tower is one of equipment that regular meeting of the classics in chemical production application involves, apply the extract that can realize a product through it, but in whole unit process of cargo bandling, rectification tower presses poor control to having crucial effect. Specific how will undertake assurance to this?

Should know what is rectification above all tower pressing is poor, it is actually regard a kind of factor that measures volume of bear of equipment interior gas as its, below normal circumstance, of rectification tower press difference basic it is changeless. If the regular stock in rectification tower balances the word that is destroyed, can cause the change that presses difference. The it is certain to press difference to have control limits of rectification tower, press poor too great too small metropolis to make the operation of rectification tower becomes unusually difficult. Want to control good rectify tower press difference, want to design some of solid of fine installation itself to press difference on one hand, also be the limitative condition that goes up according to the operation after be being proved through scientific computation, undertake transforming to equipment again. It is poor to handling middling pressure change on the other hand, enter makings bear, circumfluence in order to become, when producing change to cause a tower to press change into the element such as dosage of material composition, cooling water, the tower presses difference to also can follow change, the adjustment that controls tower pressing right now will be automatic movement, make the tower presses difference to return to normal. In this two respects cooperate jointly under, meeting control is in the ability pressing difference of rectification tower inside proper limits, because of,avoid bigger or lesser press difference and use the effect actually of influence rectify tower.
