At 10:26 on October 26, the normal pressure reduction device II of China Petroleum Guangdong Petroleum and Chemical Refining and Chemical Integration Project (hereinafter referred to as Guangdong Petroleum and Chemical Project) located in Jieyang City successfully introduced crude oil, marking that the project has entered the start of the production and trial production stage of materials.
Normally decompression distillation device II is the leading device of Guangdong Petrochemical Project. The design processing capacity of is 10 million tons/year, the annual start-up hours are 8,400 hours, the device design elasticity is 60% to 110%, and the design operation week is period for four years. The device adopts high vacuum decompression deep pulling technology, and provides raw materials for downstream continuous reforming, aviation coal hydrogenation, diesel hydrogenation and other devices; at the same time, narrow-point technology is used to optimize the heat exchange network, make full use of the device's waste heat to achieve the purpose of reducing energy consumption.
This device was completed by China Petroleum East China Design Institute Co., Ltd., and China Petroleum Engineering Construction Co., Ltd. (CPECCh) is the general contractor of for construction. Since the construction of installation was launched in March 2020, Guangdong Petrochemical Company, with the support and cooperation of Jieyang Municipal Party Committee and Municipal Government and Dananhai Industrial Zone, has scientifically coordinated and accurately deployed, and strictly grasped the four key points of progress, safety, quality and cost. It took 27 months and was handed over to on on June 26, 2022. In production preparation work, the majority of project builders are inspired by the oil spirit of "hard work" and "three elders and four strictness", and take the Party member commando and the Youth Commando as the backbone to lock in all urgent, difficult, dangerous and heavy tasks, strive to overcome difficulties, and achieve trial production of equipment production by stepping on the spot.
This time the production of materials was trial production, Guangdong Petrochemical Company comprehensively considered the balance of materials, cost reduction, safety, green and environmental protection throughout the process, and other factors such as normal pressure reduction device II will produce at a load of 70% for 10 days, and a total of 199,920 tons of crude oil was processed, and it cooperated with naphtha hydrogenation and other six other sets of devices such as naphtha hydrogenation that started in the same batch of . provides oil transport, catalyst vulcanization oil and some devices for subsequent equipment start construction.
Guangdong Petrochemical Project is the largest refining and chemical project with one-time investment in China Petroleum Corporation. It is currently the only refining and chemical base in China that can process all inferior heavy oil . Compared with refining and chemical companies of the same scale, the added value of the product can be increased by 25% and the energy consumption is reduced by about 15%. Relying on good crude oil adaptability, it processes 20 million tons of crude oil annually, and can produce 1.2 million tons of ethylene products and 2.6 million tons of aromatic products. This is of great significance for China Petroleum Corporation to realize the refining and chemical business to the middle and high end of the industrial chain and value chain .
Guangdong Petrochemical Project is located in a key position in the "coastal economic belt" of Guangdong Province. After production, the supply of synthetic resin products can be increased by 2.5 million tons per year in in the south China region alone, significantly reducing the dependence of external to industrial chemical raw materials such as household appliances and electronics in the Guangdong-Hong Kong-Macao Greater Bay Area. The engine effect formed will drive the improvement of the petrochemical industry chain in eastern Guangdong, accelerate the formation of the 4 trillion-level green petrochemical industry base in Jieyang Dananhai Petrochemical Industrial Zone, and further improve the level of regional coordinated development in Guangdong Province.
