The cost of material purchase was the highest one, about 59% of the internal cost,while the majority of the external cost was the cost of crude oil exploitation,about 45% .Theinternal key cost was material purchase,and theexternal key cost included thecrudeoil exploitation,ethylene productionandpolyethyleneproduction.Thismodelcouldbeusedto quickly and efficiently implement life cycle cost of polyethylene plant , supported for the energy saving of related enterprises. : olyethylene;lifecyclecost;cost assessment;key costsp (PE) , 2015 [1] , , 、
