From rectification tower is introducing with everybody all the time before early, but internal to it institute has rectification technology is not to understand exceedingly, include the requirement of the definition of rectification and rectify, it is to serve as the basic knowledge that needs to master for the user.
Will what understand above all is rectification, so called rectify is in using liquid state or gaseous compound each groups portion volatile or of boiling point different, have method of detached a kind of reaction to its thereby. It is difficult to should accomplish this to say not difficult also, but say simple also not simple, want to accord with relevant condition only, rectification can be successful undertake. Afore-mentioned says conditions basically include to have, it is to enrage fluid photograph to must be contacted adequately on one hand, the design inside rectification tower has multilayer tray is the condition that offers gas fluid to be contacted adequately; On the other hand, when gas fluid two-phase is contacted, the chroma of small group share in ascendant high temperature gas phase wants the chroma when prep above is balanced, and the chroma of small group share in descendent microtherm fluid photograph wants under the chroma when the balance. Such word, because gas fluid two-phase is lopsided,exist temperature is poor, ability makes happen to conduct heat and conduct qualitative process between its, have rectification effect eventually.
