Produce different chemical product, the tower that uses implement also be different, if aldehyde is produced, shrinking e.g. armour is catalytic tower and rectification tower commonly, they can be used as alone tower, also can use as integral collocation. So in actual unit process of cargo bandling, what problem can such means have?
If the tower of alone design is catalytic tower, the form of stock gas phase of cat head is entered from rectification tower bottom makings, farewell of rectification tower bottom sheds catalytic tower, circumfluence of oneself of rectification cat head. In this process, the stock that returns catalytic tower when tower bottom contains many armour to shrink aldehyde, can produce very adverse effect, somebody tries to be added in bottom of rectification tower tower again boil implement, will solve this one problem, but seem to be not actually feasible. Unless rectification tower also go up into stuff place carry, to make sure cat head is comprised, board number also wants increase naturally, but the technology issue that becomes a likelihood to also can cause other so.
