Qilu Ethylene Plant completed the second round of transformation of 720,000 tons/year in 2004, introducing the world's first triple refrigeration compressor in the ethylene industry and other advanced equipment and new technologies. From February to July 2006, two new cracking furnaces were added, with a production capacity of 800,000 tons. On the basis of digestion and absorption of imported technology, Qilu Petrochemicals olefins plant adheres to the connotation of development, relying on technological innovation to break through the limit of production capacity, implement fine management to enhance the operating quality of the equipment, make overall plans for both resource conservation and environmental friendliness, and give full play to the economies of scale after the second round of transformation. Advantages will enable Qilu ethylene to gradually enter the fast lane of sustained and effective development.
In order to solve the “bottleneck†of the high-load operation of the imported cracking gas compressor control device, the technical personnel of the plant creatively implemented the online acceleration of the compressor group, which increased the equipment load capacity by 10%, and increased the production of ethylene by 3 tons per hour, increasing the annual efficiency. 36 million yuan. In order to solve the problem of high temperature affecting the production load in the summer, they adopted measures such as expansion of heat exchangers, addition of circulating cooling water towers, etc., to keep the installations operating at high loads, and the ethylene production in the summer increased by more than 10,000 tons in the same period last year. Through optimized operation, a smooth switchover of the cracking furnace was realized. The average operating cycle of the cracking furnace reached 39.5 days. In the whole year, more than 20 sets of cracking furnaces were switched, saving more than 3 million yuan in utility projects.
The plant improves the economic operation of the plant through careful management. They strengthen basic safety management, conduct in-depth “low- and old-bad†special rectification activities, refine safety measures such as on-site construction supervision, occupational health, and accident prevention, establish and improve major hazard source information management systems, and strengthen the monitoring of key production and key production sites. Management achieved the goal of safe production. Through intensive cultivation, we will pay close attention to saving energy and reducing consumption, and implement the concept of conservation in all aspects of production and construction. For the first time, the load shedding method for the large-scale operation of ethylene plants and the shutdown of small-scale lines, with maintaining an output of more than 60 tons of ethylene per hour, the project schedule was refined to every hour through scientific demonstration and careful optimization of construction plans. The implementation of the new type of desiccant unloading operations and other major measures to complete the task of eliminating defects 84 hours in advance, increasing production of 8,000 tons of ethylene. Holding the nose of the industrial furnace, which is a large energy consumer, to strengthen the professional management of 22 industrial furnaces as a breakthrough point, and pay close attention to saving energy and reducing consumption. Standardize the operating standards of industrial furnaces, carry out "heating furnace labor competition", implement on-line monitoring of furnace operating conditions, optimize control of key process parameters affecting the thermal efficiency of industrial furnaces, and incorporate comprehensive assessments, so that the average operating cycle of cracking furnaces can be extended by 4 year-on-year. day. The introduction of a patented technology to install an air preheater for the cracking furnace enables the ethylene plant to save about 8,000 tons of fuel each year. Optimize the start-up boiler operation mode and fuel ratio, and make a good balance of steam to reduce boiler fuel and water consumption.
While pursuing the production capacity and economic efficiency of the device, the olefin plant actively promotes the clean production of the device. They increased the efforts in the treatment of industrial sewage. Through technological transformation and technological breakthroughs, they solved the “bottleneck†problem such as the unstable operation of the waste alkali oxidation system and affected the environmental protection standards, ensured that all major environmental indicators met the standards, and the amount of industrial waste discharged from the effluent decreased year-on-year. 400,000 tons. While scientifically governing industrial wastes in accordance with industry standards, we will build fuel, materials, and industrial water recycling systems to continuously increase the overall utilization of corporate resources. 43 water-saving projects were implemented and a condensate recovery network was established. The monthly recovery of condensate was more than 10,000 tons. Through the implementation of a number of process optimization projects and the elimination of runoff and leakage activities, industrial water use has decreased by 970,000 tons year-on-year, and water consumption per ton of ethylene has decreased by more than one ton compared with the same period of last year.
In 2006, Qilu Petrochemical produced a total of 388,000 tons of propylene, 324,700 tons of benzene products, and 37,700 tons of phthalic anhydride while its ethylene production reached new highs.
