GB 29141-2024Norm of energy consumption per unit production of industrial sulfuric acid, dilute nitric acid and glacial acetic acid (English PDF)

1 Scope

GB 29141-2024 is the Chinese national standard on norm of energy consumption per unit production of industrial sulfuric acid, dilute nitric acid and glacial acetic acid, 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 28 May 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 June 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 energy consumption per unit product (hereinafter referred to as energy consumption) limit level, technical requirements and Requirements, statistical scope and calculation methods. This document is applicable to the calculation and assessment of energy consumption of industrial sulfuric acid, dilute nitric acid and glacial acetic acid production enterprises, as well as new construction and expansion projects. energy consumption control.

3 Terms and definitions

The terms and definitions defined in GB/T 2589 and GB/T 12723 and the following apply to this document.

3.1 comprehensive energy consumption of sulfuric acid of industrials During the statistical reporting period, the sum of various energies input into the sulfuric acid production boundary minus the sum of various energies output outside.

Note. All types of energy input and output are converted into standard coal volume according to the prescribed method.

3.2 comprehensive energy consumption of per unit production of sulfuric acid of industrials During the statistical reporting period, the comprehensive energy consumption is expressed as 100% of the unit output of sulfuric acid.

3.3 comprehensive energy consumption of dilute nitric acid During the statistical reporting period, the various energy sources consumed in the production of dilute nitric acid using synthetic ammonia as raw material were converted into standard coal volume according to the prescribed method.

3.4 comprehensive energy consumption of dilute nitric acid of per unit product tion (100% HNO3) of dilute nitric acid During the statistical reporting period, the comprehensive energy consumption is expressed as 100% nitric acid unit output.

3.5 comprehensive energy consumption of glacial acetic acid of industrials During the statistical reporting period, various energy sources actually consumed in the entire production process of acetic acid products were converted into standard coal volume according to the prescribed method.
