Fractionating tower also is a kind when what stock rectify depart uses device, it is to should master 3 level off mainly in the operation, want the normal operation that the tower can maintain if accomplishing only. Which 3 is what 3 balances that mention here point to? How to achieve the goal of the balance through adjusting?
3 balances that fractionating tower should master in the operation are balance of photograph of fluid of stock balance, steam and balance of quantity of heat respectively, what so called stock points to evenly is the stock amount that the tower takes inside unit time should estimate the sum with all stock that leave a tower equal, what this one index reflects is the productivity of fractionating tower, basically be to enter load of bottom of makings quantity and cat head, tower to adjust. If stock balance masters bad word, can make the operation of whole tower stems from troubled waters, also can make other two balances get bad influence. And the quality that what photograph of fluid of the steam in fractionating tower basically reflects evenly is a product and loss circumstance, the case that fluid of the steam on the operation requirement that needs support adjustment tower commonly and tray contacts will achieve, also be to say, it is only if temperature, pressure is fixed, just firm steam fluid posture balances composition. Quantity of heat balances specific report to be on cat head temperature, also be the foundation that other balance realizes, very crucial. This shows, affect each other between these 3 balances, restrict each other, in be being operated, be normally give priority to in order to control stock evenly, adjust accordingly balance of quantity of heat, achieve the goal that steam fluid photograph balances eventually. Master these 3 balances of the tower, ability maintains the normal operation of the tower.
