Lanzhou Petrochemical: tapping potential, increasing efficiency and reducing energy consumption-technological advancement and strong strength
Reporter Li Chenqi and correspondent Chen Fabian reported: Lanzhou Petrochemical Company focused on the refining and chemical production and operation plan, through the implementation of "safe, stable, clean, economical, optimized, and profitable" operation measures to optimize resource allocation and effectively reduce enterprise energy It also promotes scientific and technological progress and technological efficiency, promotes scientific research and development and the transformation of scientific research results, and significantly improves the competitiveness of enterprises. In 2008, Lanzhou Petrochemical Company processed a total of 10,018,900 tons of crude oil, produced 6,741,400 tons of gasoline, coal and diesel, and 701,400 tons of ethylene. The annual operating income was 62.239 billion yuan, a year-on-year increase of 12.88%.
Lanzhou Petrochemical Company overcomes the disadvantages of a wide range of crude oil varieties and large differences in quality, increases crude oil pipeline transportation, diversifies processing methods, strives to reduce crude oil loss and processing loss rate, and realizes high-price and low-cost operation of oil refining. They also deeply optimized the processing technology and public processes, maximized benefits through production optimization, and increased the mutual supply of oil refining and chemical raw materials. In 2008, the mutual supply of oil refining and chemical raw materials reached 1.55 million tons, and the demand in the refined oil market was shrinking. Under the condition of low-load operation, the comprehensive product yield and comprehensive energy consumption of refining remained at a relatively good level, reaching 93.37% and 75.58 kg standard oil per ton respectively; the comprehensive energy consumption of ethylene was 742.04 kg standard oil per ton, a year-on-year decrease of 73.51 per ton. Kg standard oil.
In accordance with the deployment of PetroChina (11.19, 0.50, 4.68%) Group Company, Lanzhou Petrochemical Company carried out the theme activity of “Diligence and thrift, tapping potential and increasing efficiency”, identified 83 measures, implemented 17 key energy-saving and water-saving projects. With the continuous improvement of chemical capacity, in 2008, 120,000 tons of standard coal was saved and 4.66 million tons of water was saved. The fresh water consumption and domestic water consumption of the refining system were greatly reduced, and the water consumption per ton of crude oil dropped to 0.86 tons. Through the completion and commissioning of key environmental protection projects, Lanzhou Petrochemical has improved the "three-level prevention and control system", strengthened the monitoring of key projects and key pollution sources, and strictly assessed the phenomenon of excessive discharge and random discharge. In 2008, the total wastewater discharge in the plant was compared with the same period last year. It reduced 1.87 million tons, and the comprehensive qualified rate of industrial wastewater discharge reached 99.15%, an increase of 3.05 percentage points year-on-year.
Lanzhou Petrochemical Company also pays attention to the development of new products and accelerates the transformation of scientific research results. In 2008, it industrialized trial production of 30 varieties. For the first time, it developed and produced 8 new products such as special materials for bottle caps and environmentally friendly styrene butadiene rubber. Development and other 8 projects have won the first, second and third prizes of China National Petroleum Corporation's scientific and technological progress, and obtained 21 national patent application numbers, becoming the only national intellectual property demonstration establishment unit of CNPC.
At the same time, Lanzhou Petrochemical Company is actively implementing technical research and technological improvement measures to increase production of propylene heavy oil cracking catalyst, comprehensive utilization of catalytic oil slurry, optimized utilization of ethylene cracking heavy oil resources, delayed coking tower bottom valve and other key technologies to achieve breakthroughs. 24 technical transformation projects including gas concentration, styrene unit molecular sieve, large ethylene furnace front tank, and shape-selective molecular sieve unit vacuum system have been completed, solving a number of production problems and technical problems, and improving the technical and economic indicators of the refining unit. In 2008, Lanzhou Petrochemical Company produced 1,143,900 tons of synthetic resin, the resin production capacity ranked first in China; synthetic rubber was 122,200 tons, an increase of 80.76% year-on-year; refining catalysts were 54 million tons, an increase of 4.69% year-on-year, and the domestic market share exceeded 30%; 120 sets of special valves, with a domestic market share of over 90%.
