In the course of C_5 fraction separation the diolefin compo-nents are apt to polymerize during extractive rectificationprocesses,and the polymers thus formed are prone to plugthe trays and reboiler,which is a beast seriously constrainingthe extended and smooth operation of process units.Thusthe Chemical Engineering Research Institute of SINOPEC
