Independent Innovation Improves the Quality of Daqing Petrochemical Development

“Heterogeneous Catalytic Ozone Oxidation—Accelerating and Accelerating Aerator Active Filter Treatment of Acrylic Wastewater” passed the technical appraisal of Heilongjiang Province, and the nickel-based catalyst for hydrogenation of large ethylene pyrolysis gasoline continuously operated stably for 78 months, creating a record of domestic and foreign long-term cycle use. The development of particle size PB polymerization, agglomeration and high-gel ABS grafting technology won the first prize of the group company's technical invention. A series of scientific and technological innovations, especially independent innovations, have become an important support for Daqing Petrochemical's production and operations to reach a new level.

Daqing Petrochemical increased its efforts in scientific and technological research and developed the APS advanced plan optimization system software to timely optimize the organization of high-quality raw materials into the factory. In the first quarter of this year, the company used oilfield light hydrocarbons instead of petroleum naphtha as raw materials for cracking devices, which not only increased product yields, but also increased the production of high-grade gasoline. The diene yield exceeded 50%, creating the first domestic industry success. Ethylene energy consumption fell by 36.73 kilograms of standard oil per ton.

The company strengthened the supporting role of technological innovation and accelerated the transformation of technological achievements and the promotion and application of mature technologies. In the first quarter of this year, the company successively put into production a number of high value-added new products such as metallocene polyethylene, ABS high latex, imitation cashmere acrylic fiber, and polypropylene T40B. Among them, the ultra-large-diameter ABS latex is the first in China. Polypropylene T40B products fill the gap in the domestic production of low-index transparent polypropylene, and independently developed pneumatic thin-film high-volume sleeve control valves and other products have a strong market competitiveness.

Daqing Petrochemical focused on the integration of production and research, and successively cooperated with several units such as Daqing Chemical Research Center and Zhongkai Chemical (Dalian) Company to develop four achievements. CPI sewage treatment plant poisonous and harmful gas treatment technology, completely solve the CPI device environmental pollution problems; high efficiency adsorption and membrane separation combination process, so that the yield and purity of ethylene, hydrogen is significantly higher than the level of similar domestic devices; oil loading anti-track derailment safety The control system solves the problem of wheel rails traversing the crawler drill and the oil tanks to ensure the safety of oil loading operations; in particular, the advanced acrylic acid wastewater treatment project has passed acceptance and provides technical support for the discharge of the acrylic wastewater.
