GB/T 46870.1-2025 Active

After combustion in power plants, the CO2 capture device (PCC) separates carbon dioxide (CO2) from the power plant flue gas, and then transports, utilizes, and geologically stores it. This document specifies the methods for performance measurement, evaluation, and reporting of PCCs in power plants, providing a common method for calculating key performance indicators (KPIs) of PCCs, while defining the boundaries of typical systems and determining the measurement and calculation methods for KPIs. This document applies to thermal power plants that burn carbon-based fuels (such as coal, oil, natural gas, and biomass fuels), which generate CO2 through boilers or gas turbines and are combined with CO2 capture devices. This document applies to post-combustion CO2 capture technologies based on chemical absorption, using chemical reaction absorbers such as amine solutions, potassium carbonate solutions, and ammonia water. This document does not apply to post-combustion CO2 capture technologies based on other principles (such as adsorption, membrane separation, and low-temperature processes). The PCC in power plants can be used to capture CO2 from all or part of the power plant flue gas. According to the requirements for transportation, utilization, and storage, the captured CO2 is processed in subsequent compression or liquefaction steps.
