Carbon dioxide capture and post-combustion carbon dioxide capture System General Requirements

1 Scope

GB/T 46877-2025 is the Chinese national standard covering the amine capture plant bolted onto a power station or a cement works - the absorber and stripper, the solvent and its degradation and emissions, the steam it takes from the host plant and the capture rate it must achieve. First edition, and it is the front end of the chain the storage standards of this batch complete. It was issued on 31 December 2025 and has been in force since 1 July 2026, as a first edition. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the classification, composition, and technology of post-combustion carbon dioxide (CO2) capture systems (hereinafter referred to as "carbon capture systems"). Require. This document applies to the design and construction of post-combustion CO2 capture systems (excluding experimental setups).
