The rectification technology that involves in rectification tower has had a lot of, press rectification, decompression rectify, constant boil rectify to wait a moment than as usual, but here still has rectify of a kind of transformation to was not involved. Take the advantage of this opportunity as it happens to complement the knowledge of this respect, facilitating everybody is patulous intellectual face.
In fact, transformation rectify is one kind applies to pressure sensitivity in all the detached method that boil content fastens, and content is sensitivity of so called pressure, those who point to is be in all the change that boil composition produces along with pressure change is more than 5mol% , or in all the content that boil disappears is. Also be to say, if in all boil content has sensitivity to pressure, the one aspect of the matter that perhaps forms rectification border after introducing carry secretly agent has sensitivity to pressure, when other rectify technology cannot apply, can use the method with transformation detached rectify. According to different level, transformation rectify can be divided into different sort, for instance according to illuminate in all if boil content is divided to the sensitive degree of pressure, have common transformation rectify and the transformation rectify that introduce carry secretly agent; If according to in all if the discretion of boil content boiling point is divisional, low in all rectify of boil content transformation and tall in all rectify of boil content transformation is so come. Besides, still can regard classification as in order to heat up compositive degree the basis, cent is become heat up compositive transformation without rectify of hot compositive transformation, part rectification and rectify of completely hot compositive transformation 3 kinds. In real operation specific choose which kind of transformation rectify, return so that decide according to specific operating mode.
