The past decade has been a period of rapid development in China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also seen significant progress, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and increased use of domestic equipment. Everyone is welcome to share their thoughts and insights; let’s cheer for Made in China and support the development of chemical processing equipment! *********************************** The Huangcaoxia Gas Storage Facility is located in Changshou District, Chongqing, and is a key project for natural gas infrastructure development under the 14th Five-Year Plan. On October 12, 2021, the BCL404/A centrifugal gas injection compressor unit at the Huangcaoxia Gas Storage Facility of CNPC’s Southwest Oil and Gas Field Company passed a 72-hour trial operation assessment, achieving a maximum daily gas injection volume of 3.2 million cubic meters. This marks the successful one-time commissioning of the first domestic centrifugal compressor unit for gas injection in gas storage facilities, setting a precedent for the use of centrifugal compressor units in such gas injection processes in China. Shenmu Group was responsible for the design, manufacturing, and overall assembly of the compressor units used in the core equipment’s gas storage facilities. To meet customer needs and ensure the smooth commissioning of the project, SHENGU Group deployed its most skilled personnel during the equipment installation and debugging phase, completing the tasks on time and as scheduled, thereby achieving \"integration of service and manufacturing\".
The maximum daily inflation volume reaches 3.2 million cubic meters; high pressure enables large flow rates
I have only used centrifugal oxygen compressors of 3.0Mma; I don’t know what the pressure is for models other than this one. Guessing from the model, is the flange 4.0 Mpa? It seems like it should be even higher :)
The dry gas seal of the centrifugal gas injection compressor at the Huangcaoxia gas storage facility, operated by CNPC Southwest Oil and Gas Field Company, passed a 72-hour continuous operation test successfully; the maximum daily gas injection volume reached 3.2 million cubic meters. This marks the first successful operational test of a dry gas seal for a centrifugal gas injection compressor in a gas storage facility in China, setting a precedent for the use of such compressors in this application. The compressor’s design pressure is as high as 21.25 MPa, making it the pipeline compressor with the highest pressure dry gas seal available to date. It utilizes high-pressure dry gas seal technology developed independently by Zhongmi Holding, ensuring that the sealing performance meets the desired standards.
Shenmu has been very impressive in terms of large-scale compressor equipment these past few years
Yes, it seems that Mitsubishi technology was introduced in the early years, and I played a role in developing its oil return system; P
In practice, it’s always possible to discover some good things
