Norm of energy consumption per unit production of refining and chemical industry 1 Scope This document specifies the technical requirements, statistical scope and calculation method for norm of product energy consumption (hereinafter referred to as energy consumption) for refinery, ethylene, polypropylene, styrene, purified terephthalic acid, p-xylene, propylene oxide and phthalic anhydride. This document is applicable to the calculation and assessment of energy consumption in the production processes of refinery, ethylene, polypropylene, styrene, purified terephthalic acid, p-xylene, propylene oxide and phthalic anhydride, as well as the energy consumption control for newly built or renovated (expanded) projects. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
