On July 4, the rotational speed of the GB-801 three-way refrigeration compressor for the ethylene plant of Qilu Petrochemical Company increased from 4,450 rpm to 4,700 rpm. After several days of trial operation, the effect was good. At this point, the “bottleneck†that severely restricted the high-load production at the end of the operation of ethylene units at Qilu Petrochemical was eliminated.
The GB-801 compressor was the new equipment in the second-round transformation of Qilu ethylene in 2004, and it was the world's first three-element refrigeration equipment for ethylene production. After nearly four years of long-term operation, the equipment had problems such as lack of power, unstable system operation, and increased ethylene loss. The company's technical staff collected a large amount of operating data and found that the operation time at high temperatures caused a deviation in the operation of the valve position, resulting in a decrease in the compressor's functional capacity. This is in accordance with the successful implementation of the GB-201 cracked gas compressor online acceleration in 2007, the company's technical personnel once again to carry out technological transformation of large-scale equipment with international advanced technology.
