Membrane systems in polyethylene plants-An update

摘要

The single largest operating cost in the manufacture of polyethylene is the cost of the feedstock.In the case of a gas-phase polyethylene plant which produces either high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE),the feedstock is a combination of monomers such as ethylene,butene,and hexene-1.
