China's first centrifugal compressor unit that can handle the production of 1.2 million tons of ethylene per year passed product inspection by China Machinery Industry Federation and China General Machinery Industry Association in Shenyang, capital city of Liaoning province, on Dec 10.

“The device was successfully commissioned in the second phase of an ethylene plant project of CNOOC and Shell Petrochemical Co (CSPC) on Nov 27, 2017; and achieved continuous and stable operation.” said Dai Jishuang, chairman of the Shenyang Blower Works Group Corporation (SBW Group).

“It’s a major technological breakthrough for the homegrown device for ethylene production." Dai added.

The centrifugal compressor unit is the "heart" of an ethylene production plant. It will cause irreparable damage to the ethylene production line if something goes wrong with the compressor unit.

Currently, only a few developed countries such as America, Germany and Japan have the manufacturing technology and capacity to produce a centrifugal compressor unit that can handle the production of a million tons of ethylene per year.

The centrifugal compressor unit tested and adopted by CSPC belongs in a class of compressors with the largest size and throughput level in the world. Its core sections, including cracking gas, ethylene and propylene compressor units, are all developed and installed by SBW Group.

In recent years, SBW Group insisted on independent research and innovation; successively breaking the international monopoly on centrifugal compressor technologies and achieving the “triple jump forward” in centrifugal compressor development by making possible a production capacity for 800,000 tons, 1 million tons and 1.2 million tons of ethylene.

Over the past years, after the device manufacturing technology was ironed out, SBW Group has already produced a total of 68 centrifugal compressor units for ethylene production.
