On June 12, the 800,000-ton/year ethylene plant cracking furnace compressor (C-3001) of the Changqing ethane-to-ethylene project, which was contracted by Beijing Huanqiu Company and constructed by Huanqiu Sixth Construction Company, was successfully tested at no-load.
All the mechanical properties meet the design standards, which lays the foundation for the start-up of the ethylene plant
.
The personnel at the operation site, the engineer station between the ethylene cabinets, and the central control room simultaneously recorded, observed and compared various performance indicators of the unit.
The operators in the “three places” kept their eyes on various mechanical indicators of the cracking gas compressor.
By 19 : 50, the compressor speed reaches 5112r/min.
After passing the examination for 20 minutes, the speed will be increased to 5368r/min immediately, and the examination will pass in 5 minutes.
At 20:20, the examination has successfully completed the various test indicators
.
The main features of the steam turbine are high parameters, high power and large extraction steam capacity.
Its rated power is 13749kw, rated speed is 4012r/min, rated steam flow rate is 92.
7T/h, maximum continuous working speed is 4544r/min, steam inlet temperature is 375℃, The extraction steam temperature is 279.
3℃, and the extraction steam pressure is 1.
588MPa(G)
.
The cracked gas compressor is the core equipment of the ethylene plant.
It is called the "three units" together with the propylene refrigeration compressor and the ethylene compressor.
It is the core equipment of the core equipment of the ethylene plant.
The "three units" of the unit are all selected by Beijing Huanqiu Company.
, Design, designed and manufactured by Shenyang Blower Group Co.
, Ltd.
, some ancillary equipment is provided by other domestic manufacturers, and the localization rate is 100%
.
Since the unit was installed in November 2020, it has been highly valued by leaders at all levels of relevant units.
In order to ensure the smooth installation of the unit, Huanqiu Sixth Construction Company selected experts to guide the installation of centrifugal compressors.
All installers have been trained and qualified, and the installation process is standardized.
order, safe and reliable, foolproof
