1 Scope

GB 29436-2023 is the Chinese national standard on norm of energy consumption per unit production of methanol, ethylene glycol and dimethyl ether, 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 27 November 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 December 2024. 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 stipulates the limit levels, technical requirements and statistics of energy consumption per unit product of methanol, ethylene glycol and dimethyl ether (hereinafter referred to as energy consumption): Scope and calculation method: This document is applicable to the calculation and assessment of energy consumption by the following manufacturing enterprises, as well as the energy consumption control of new construction and renovation and expansion projects:
