For the depart that is aimed at different composition, adoption detached method also is different, so what is depart of deep low temperature? In what kind of equipment is it finished?
Want to realize depart of deep low temperature, must have raw material enraging liquefaction above all, what press its each constituent condensing temperature next is different, depart gives each constituent. Afore-mentioned whole and separate courses come true in tower of rectify of deep low temperature, this kind of method is applied to be enraged by the raw material of close of detached constituent condensing temperature, be typical application is from inside air detached oxygen is mixed nitrogen. Deep low temperature can realize separate course not only, still can undertake adsorption, it is the character that uses porous solid sorbent to have choice adsorption, constituent of adsorptive and certain impurity falls in deep low temperature, in order to obtain the means of pure product. According to the need of craft, use a kind of principle alone sometimes, sometimes a few kinds of principles are used at the same time, achieve expectant goal.
