The annual ethylene output of Daqing Petrochemical increased to 1.2 million tons for the first time
In the face of fierce market competition, huge pressure to reduce cost and increase efficiency and the reshuffle of the refining and chemical industry, Daqing Petrochemical has made breakthroughs and achieved fruitful results in 2019, processing 6.04 million tons of crude oil, producing 448,000 tons of synthetic ammonia and 1.288 million tons of ethylene, and achieving 1.2 million tons of ethylene production for the first time. 11 sets of plants (production lines) set a long cycle operation record, and the main business has maintained a profit for four consecutive years.
Adhere to the general tone of seeking progress in stability, and give play to the advantages of refining and chemical integration. In accordance with the principle of "suitable oil for oil, cheap oil for oil", Daqing Petrochemical optimized the production and operation plan, timely adjusted the balance of refining to increase chemical raw materials and refined oil products. Make good use of the surplus components of aviation coal, diesel oil, wax oil and other resources that can be used as chemical raw materials, and the supply of heavy cracking materials and tail oil exceeds 3,600 tons/day, reaching the historical maximum throughput; Ethylene "breaking one million tons" production record was updated to 284 days, the production cycle hit the shortest in history. The improvement of ethylene production capacity led to the development of the "chemical tail" industry chain, the overall load of downstream production plants increased, and the total amount of chemical commodities reached 3.8 million tons, an increase of 24% over the previous year.
Driven by the construction of large projects, the pace of transformation and upgrading is firm. Following the completion and operation of MTBE, alkylation and acid making units, the transformation and upgrading project of Daqing Petrochemical Refining structure adjustment and optimization has been steadily promoted in 2019. The 1.2 million tons/year continuous reforming unit was completed, the settler and regenerator of the catalytic cracking unit were capped at 2 million tons/year, and the 600,000 tons/year gas fractionation unit entered the installation stage, completing 72% of the planned total investment of the project. "The beautiful blueprint is increasingly clear, and the industrial agglomeration effect brought by large-scale and integration is more and more obvious. The output of 18 kinds of products and 24 indicators of energy and material consumption reached the best in history, helping enterprises to speed up and improve quality and efficiency.
Continued to promote cost reduction measures to improve the actual effect of tapping potential. Taking the maximization of efficiency as the direction of efforts, Daqing Petrochemical consolidated the foundation, practiced internal skills, carried out standard management with China's first-class enterprises, adhered to the problem orientation and goal orientation, and did a solid job in the optimization of raw material structure, product structure, production plan, energy utilization, etc., made full use of the existing equipment conditions, and excavated the efficiency potential in cost control, production increase, cost reduction and other aspects. To release the effective production capacity of the plant. At the same time, we strengthened process supervision, tracked the implementation of key potential exploitation projects, strictly controlled the threshold of new projects, scientifically controlled the deviation of potential exploitation quotas, and increased efficiency by 330 million yuan for the year.
