Three yuan refrigeration compressor to achieve online speed In the afternoon of July 4, Qilu Petrochemical Company ethylene plant GB-801 three yuan refrigeration compressor on-site, hot sauna days so that people's cotton tooling was saturated with sweat. The technical staff and operators of the cracking workshop GB-801 improvement team were on the spot and various preparations were put in place one after another. Around four o'clock, with the order of the director of equipment Cui Haibing, the equipment and process cooperated with each other and began to implement the compressor online in an orderly manner. Speed ​​up. At about 6 o'clock, the compressor speed was increased from 4450 rpm to 4700 rpm, and the target was successfully achieved. After three days of trial operation, the effect was good, and this “bottleneck†that severely restricted the high-load production at the end of the plant operation was eliminated.
The GB-801 compressor was the new equipment in the second-round transformation of Qilu ethylene in 2004. At that time, it was the world's first three-factor refrigeration equipment used in ethylene production. It was known for its advanced technology and difficult operation. After a long period of operation in the last four years, recently, problems have arisen such as lack of function, resulting in unstable operation of the system and increased ethylene loss. The cracking workshop has set up an improvement team consisting of equipment, process technicians, and first-line technical backbones. The division of labor is responsible for carrying out technical research. They collected a large amount of operational data and used the compressor control principle to analyze the cause of the failure because the high temperature and long running time caused valve position operation deviations, which caused the compressor to reduce its power. After several rounds of “brainstorming†type of in-depth discussions, the improvement team optimized the safest and most ergonomically feasible programs out of the three programs.
This is in accordance with the device's successful implementation of the GB-201 cracked gas compressor online speed increase in 2007, the device technicians independent innovation, once again the technical improvement of large-scale equipment with international advanced technology.
