[Chemical Equipment Powerful Equipment] 082-Nationally produced printed plate heat exchanger
Thread Content
The past ten years have been an era of great development for China's chemical industry. The emergence of many new processes, new products, and new equipment has also led to a great development in my country's chemical equipment, which has also promoted the rapid development of the petrochemical industry. Here we have collected and sorted out some of the achievements and breakthroughs made by my country's equipment companies in the large-scale and localization of equipment. Welcome everyone to share, discuss, and exchange, cheer for Made in China, and cheer for chemical equipment! * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * On May 7, 2020, the nationally produced printed plate heat exchanger independently developed by China Shipbuilding Industry Corporation 725 was successfully used in my country’s first self-operated deepwater 100 billion cubic meter large gas field - the Lingshui 17-2 gas field development project. The first engineering application of this fully independent product makes 725th Institute the second company in the world to have application performance of printed plate heat exchangers in the field of marine engineering. It is understood that the printed plate heat exchanger is a disruptive and innovative micro-channel heat exchanger. In offshore natural gas processing systems, it is mainly used for cooling natural gas before export. The space of offshore platforms is limited, and ordinary heat exchangers are large in size and weight, and cannot meet the space and weight restrictions of the platform.
“The natural gas mined by "Deep Sea No. 1" needs to be highly compressed before being exported, and the pressure can reach 180 atmospheres. This will cause the natural gas to heat up suddenly, which is not conducive to the safety of transportation. The 100% nationally produced industrial-grade printed plate heat exchanger (PCHE) provided by the No. 725 Research Institute for the "Deep Sea No. 1" energy station can effectively reduce the temperature of compressed natural gas and ensure that the natural gas mined and processed by "Shen Hai No. 1" can be safely transported to thousands of households. It is one of the key equipment for oil and gas processing in the upper block of the "Deep Sea No. 1" energy station.
“The design standard of the "Deep Sea One" energy station is "no return to dock for 30 years", which means that this maritime giant will have to fight non-stop against harsh environments such as high temperature, high humidity, high salt spray, and super typhoons for 30 years! In addition to nationally produced printed plate heat exchanger products, the 725th Institute also provided seawater pipeline copper-nickel alloy fire piping and public seawater piping products for the "Deep Sea No. 1" energy station, as well as key technical services such as metal material composition and performance testing and evaluation, welding process evaluation, anti-corrosion material testing and anti-corrosion evaluation. It also dispatched metal materials, welding and anti-corrosion experts to participate in the on-site technical work in Qingdao and Yantai throughout the entire process, providing an important guarantee for the successful construction and smooth commissioning of "Deep Sea No. 1".
