Recently, a good news came from Daqing Petrochemical Chemical No. 1 Plant: As of 10:00 am on December 21, the plant has produced 601,000 tons of ethylene this year. It is expected that the annual ethylene output will exceed 615 thousand tons, which is 600,000 tons of Daqing Petrochemical ethylene plant. For the first time since the transformation, the production capacity has been achieved.
The 300,000-ton/year ethylene plant of Daqing Petrochemical Chemical Plant began in 1986. Since it was completed and put into production, it has experienced three large-scale renovations and expansions. In 2004, the designed capacity reached 600,000 tons per year.
Over the past few years, the plant has been making efforts to overcome the bottleneck of the device, increased technological innovation and management innovation, adopted a standardized production management system, and implemented a series of production optimization and technological transformation. In order to eliminate the bottleneck of high energy consumption and low yield of the old devices, they actively carried out technological transformation to enhance the hard power of the device. In view of the fact that the old cracking plant has a long service life and high energy consumption, the project of optimizing the cooling oil viscosity reducing system was implemented to achieve the series operation of the quench oil system in the new and old areas, and the quench oil quality was stabilized. The annual efficiency increase was 87.36 million yuan.
Since the beginning of this year, the plant has implemented a cracker radiation section reconstruction project, replacing the 16 W-radiant furnace tubes of the G furnace with 48 U-tubes to reduce the residence time and increase the yield of diene. The annual output of ethylene is increased. 924 tons, 394.4 tons of propylene, creating more than 1,300 million. They also carefully carried out benchmarking analysis, clearly defined the direction of improvement, implemented multiple production optimization measures such as on-line switching of cracking furnaces and the introduction of pyrolysis by-products to the quenching system in place of tempered oil, and significantly reduced the product consumption index.
A number of technical reform initiatives have brought vitality to the old ethylene plant of Chemical Industry Plant. On December 21st, the plant produced a total of 601,000 tons of ethylene, which was the first time since its transformation.
