a) The scope of application of the standard has been changed (see Chapter 1, GB 30251-2013, GB 30250-2013, GB 31533-2015, GB 31534-2015, GB 31826-2015, Chapter 1 of GB 32053-2015);

b) Added the energy consumption limit level per unit product (see Chapter 4);

c) The energy consumption quotas for oil refining, ethylene, polypropylene, styrene, paraxylene and purified terephthalic acid have been changed, and propylene oxide has been added: and phthalic anhydride energy consumption limit indicators (see Chapter 4, GB 30251-2013, GB 30250-2013, GB 31533- 2015, GB 31534-2015, GB 31826-2015, Chapter 4 of GB 32053-2015);

d) Deleted the "advanced value" and the diolefin energy consumption limit index (see Chapter 4 of GB 30250-2013);

e) Deleted energy-saving management and measures (see GB 30251-2013, GB 30250-2013, GB 31533-2015, GB 31534- 2015, GB 31826-2015, Chapter 6 of GB 32053-2015);

f) Revised the reference value of energy and energy-consuming working fluid conversion standard oil coefficient (see Appendix A), revised the energy coefficient of oil refining production equipment (See Appendix C), revised the energy factors of storage and transportation systems, sewage treatment plants, thermal losses, power transmission and transformation losses, and other auxiliary systems (See Appendix D);

g) Added the calculation method of polypropylene standard product output (see Appendix F): Please note that some of the contents of this document may involve patents: The issuing organization of this document does not assume the responsibility for identifying patents: This document is proposed and coordinated by the Standardization Administration of China: The previous versions of this document and the documents it replaces are as follows:

1 Scope

GB 30251-2024 is the Chinese national standard on norm of energy consumption per unit production of refining and chemical industry, in the field of energy and heat transfer engineering. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 29 April 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2025. Classification: ICS 27.010, CCS F01. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the production of oil refining, ethylene, polypropylene, styrene, purified terephthalic acid, paraxylene, propylene oxide, phthalic anhydride, etc: The technical requirements, statistical scope and calculation method of the energy consumption (hereinafter referred to as energy consumption) limit of products: This document is applicable to the production of oil refining, ethylene, polypropylene, styrene, purified terephthalic acid, paraxylene, propylene oxide, phthalic anhydride, etc: Calculation and assessment of energy consumption in the production process, as well as energy consumption control for new or modified (expanded) projects:
