According to an April 1 report from Sohu News, Guochu Technology (Xiamen) Co., Ltd. recently received good news: relying on its outstanding technical strength, comprehensive product solutions, and high-quality service system, the company successfully won the bid for the deoxygenation system project of the EPC general contracting project for the aboveground works of the Tongchuan Yaozhou District 350MW/1400MWh Compressed Air Energy Storage Power Station Project.
Winning this bid marks that the technical strength of Guochu Technology (Xiamen) Co., Ltd. in the field of large-scale energy storage has once again been recognized. Prior to this, Guochu Technology also won the bid for the deoxygenation system project of the Gansu Jiuquan 300MW Compressed Air Energy Storage Power Station.
The Tongchuan Compressed Air Energy Storage Power Station is the first compressed air energy storage power station in Shaanxi Province and the world's first large-tank type 350-megawatt artificial cavern compressed air energy storage power station. As the world's first project to build a gas storage facility in limestone strata, it has been included in the National Green and Low-Carbon Advanced Technology Demonstration Projects and the first batch of independent energy storage pilot projects in Shaanxi Province.
As an important heat exchange medium in compressed air energy storage power stations, the effectiveness of circulating cooling water deoxygenation is related to the anti-corrosion protection of circulating water pipelines and heat exchangers and their long-term safe operation, and is a key link in ensuring the efficient, stable, and long-cycle operation of the power station. Traditional thermal deoxygenation, chemical deoxygenation, and other technologies suffer from problems such as high energy consumption, high costs, and secondary pollution, making it difficult to meet the stringent requirements of energy storage systems for efficiency, environmental protection, and stability.
Guochu Technology (Xiamen) Co., Ltd. has been deeply engaged in separation and purification technology for many years, always adhering to technological innovation and quality first, focusing on the equipment needs of industries such as new energy, energy storage, and electric power, and has created a series of complete equipment products with excellent performance, strong adaptability, and high reliability.
In view of the operating conditions and technical requirements of this compressed air energy storage power station, Guochu Technology (Xiamen) Co., Ltd. tailored a professional ambient-temperature deoxygenation system solution. This product combines the advantages of ambient-temperature operation, high-efficiency deoxygenation, stable performance, energy saving and environmental protection, and easy operation and maintenance, fully meeting the high-standard, high-load operation requirements of large-scale energy storage power stations. It can effectively remove dissolved oxygen from water, prevent oxidative corrosion of equipment and pipelines, extend the service life of the power station's core equipment, reduce later operation and maintenance costs, and help the power station achieve efficient, safe, and stable operation.
