Sinopec News Network reported on June 6th that the Gulei Refining and Chemical Integration Project undertaken by Shijian Company had a successful no-load test run of the 800,000-ton/year ethylene plant cracking gas compressor unit, marking the start of the Gulei Refining and Chemical Ethylene Project.
Preparation stage
.
It is understood that the compressor unit is the core equipment of the ethylene plant.
The no-load test power of the compressor unit is 29225 kilowatts, the speed is 4795/min, and the maximum design pressure is 4.
2 MPa
.
In order to ensure a successful trial run of the compressor unit, the staff involved in the construction of the ethylene branch of the Shijian Gulei refining and chemical project battled high temperatures and scorching heat, overcoming the impact of many unfavorable factors such as tight construction period and complex working environment, and successfully completed 11 in only 12 days The stress-free piping construction has laid a solid foundation for the realization of high-quality test runs of the compressor unit
.
Subsequently, after 3 days of high-intensity day and night fighting, the ethylene plant cracking gas compressor shaft system vibration, temperature, and inlet and exhaust pressures operated smoothly, all within the design range, creating good conditions for subsequent load test runs
.
Before the commissioning, the compressor leading group of the project department optimized and perfected the commissioning plan to ensure that the commissioning work was foolproof
Because the construction of the cracked gas compressor unit of the ethylene plant faces the influence of unfavorable factors such as the large diameter of the ultra-high pressure steam pipeline, the thickness of the pipe wall, and the narrow working space, the construction of the piping and the flange facing the mouth has increased a lot of difficulty
.
According to on-site construction conditions, the project department has scientifically organized, carefully deployed, and deployed lean construction forces to successfully complete the stress-free piping work of the compressor unit, making full preparations for the smooth start of the commissioning work
At present, the employees participating in the construction continue to keep up with the trial operation status of the compressor unit, which provides a strong guarantee for the successful start-up of the Gulei Refining and Chemical Ethylene Plant
