Which domestic ammonia centrifugal compressor performs best?

Yes, Shengu is good, and what about Sichuan...

This post was last edited by Huang Xinhui on 2010-1-2 09:23 Syngas compressor unit is the most difficult unit to design and manufacture among the "five major units". Its compressor has high pressure, large pressure ratio, and the process medium (hydrogen and nitrogen is about 3: 1) The components are unstable, have small molecular weight, are flammable and explosive, and require high rotation speed and high shaft power. Due to its high speed, high steam parameters, complex structure (steam extraction and condensation), large extraction steam volume and high parameters, and the function of medium-pressure steam balance, the steam turbine is the largest steam turbine designed and manufactured in large fertilizer plants. It seems that the following manufacturers have certain qualifications and performance. Among them, the compressors include Shenyang Blower Factory and Jinzhou Xinjin Chemical Machinery Factory, while the turbine manufacturer, Hangzhou Steam Turbine Factory, has been successfully tested in the 50% capacity expansion transformation of Ninghua Second Chemical Fertilizer. Of course, what I said is all * * situation inside!

In China, Siemens Industrial Turbomachinery Co., Ltd. (Jinhua Machinery) has the strongest capabilities, and it seems that very few drum sinkers can do more than 10.0MPa. There are also Shaanxi drums to check out. There are basically three large compressor companies in China.

Large ones in China can only achieve 300,000 tons and a pressure of 11 MPa, even large ones can't.

Domestic sinking drums provide Dalian Fujia Group with compressors with outlet pressures exceeding 25.0MPa. Many of Shengu's achievements are in the petrochemical industry!

Domestically, Shengu Chemical Machinery and Xinjin Chemical Machinery have good performance.
