The norm of energy consumption per unit product of ethylene plant

1 Scope

This Standard specifies the technical requirements, statistical range, calculation method, energy-saving management and measures of the norm of energy consumption per unit of product of ethylene plant.

This Standard applies to the calculation and evaluation of the energy consumption for the ethylene plant that uses petroleum hydrocarbons as the materials for producing ethylene, propylene, mixed C4, pyrolysis gasoline, hydrogen, and other products after being processed by steam pyrolysis, quenching, compression and separation, and the energy consumption control of new projects.
