【Abstract】 The algorithm of N m +1 and R m of batch distillation of a batch of binary mixture under constant reflex ratio is given . Separation tasks of batch distillation of binary mixture under constant reflex ratio are designed by Orthogonal Collocation Method within often application, and itsN m+1 、 R mand R relative to N+1 are calculated. An approximate relation,Y=0.822-0.742X 0.525 , is set up through correlating the calculation results , and its application method is introduced by example更多还原
