The carbon dioxide capture and utilization test platform project is located in Beiqijia town, Changping district, Beijing. It is an experimental project for the capture and utilization of carbon dioxide in flue gas. According to the relevant parameters of the pilot test platform provided by the employer, deepen the design and construction of the gas supply and distribution system, so as to meet the requirements of remote control, automatic and accurate gas distribution for natural gas, nitrogen and carbon dioxide. After passing through the gas heater, safe, continuous and stable gas output under various working conditions can be met, and the discharged flue gas (including combustible gas) can be automatically, safely and environmentally-friendly. That provides sufficient external conditions for the carbon dioxide capture and utilization from the flue gas produced in the future power plant production process.
