Liaoyang Petrochemical Company placed energy saving and emission reduction on the important agenda of fulfilling the social responsibility of the state-owned enterprises and its own sustainable development. It has grasped the source of prevention and control, has grasped the end of governance, and implemented fine management. In the first quarter of this year, with the addition of five sets of main production facilities, sales revenue increased by 21.82% year-on-year, COD emissions decreased by 5.9% compared with the same period of last year, and ammonia ammonia emissions in water decreased by 63% compared with the same period of last year.
PetroChina Liaoyang Petrochemical Company is an old company with a history of more than 30 years. The inherent deficiency of the industrial structure has also brought a lot of difficulties to energy conservation and emission reduction. Since the beginning of the “Eleventh Five-Year Planâ€, this large state-owned enterprise located in the Liaohe River Basin has vigorously implemented fine management, technological innovation, and international cooperation in energy conservation and emission reduction, and strived to achieve new energy conservation and emission reduction in “increase†and “decrease.†breakthrough.
Refinement can only be reduced. Ruan Chenghui told reporters that Liaozhi Petrochemical first managed to reduce the amount of compressed inventory. Liaoyang Petrochemical Company has established an energy saving and emission reduction analysis system, such as energy saving and emissions reduction notification system, weekly production scheduling meeting, and monthly economic activity analysis analysis, etc., to improve the daily consumption and environmental monitoring and analysis system for public utilities, and timely analysis. Increase or decrease the reason and guide the company's production.
On this basis, Liaoyang Petrochemical Company implemented the decomposition of energy consumption and emission reduction indicators at the workshop of the team, increased the weight ratio of energy consumption and emission reduction in the assessment, and was closely linked with the economic responsibility system, and it was among the 1,630 companies. In the first-line production team and 61 sets of key production facilities, the class composition and clean production were respectively promoted, and the enthusiasm of employees to participate in energy conservation and emission reduction was fully mobilized. Polyester workshop staff proposed that some equipment jacket cooling water should be changed from the original soft water to the use of refrigerated circulating water to achieve 5 cubic meters of water per hour. The aromatics plant employees actively recycle the 800,000 tons of PTA retrofitting project in the storage tank water injection settlement experiment, the material pipeline water injection pressure after the direct drainage as supplementary water for the circulating water, once recovery of more than 4300 cubic meters. Especially in terms of water saving, Liaoyang Petrochemical Company invested 360 million yuan to implement 21 water-saving transformation projects such as thermal chemical plant chemical water treatment process systems, and implemented "one water and four uses" in adipic acid and other devices by adjusting production processes and other measures. In other comprehensive water-saving measures, the company's daily water consumption has dropped from the past 240,000 tons to the current 120,000 tons.
At the same time as pollution reduction at the source and end-of-pipe treatment, Liaoyang Petrochemical Company, in line with the principle of “emissions compliance, effective emergency measures, and prevention and control of wastewater at the tertiary level,†seriously sought out environmental hazards, and invested more than 400 million yuan for the identified problems. There are 14 environmental protection projects and 6 wastewater pollution prevention and control measures have been completed. After these projects were completed, they played a significant role in the prevention and control of pollution. Liaoyang Petrochemical Company implements on-line monitoring and management of all sewage outlets, timely monitoring of key sewage outlets, timely notification, accurate assessment and management in place. The production equipment strictly controls the production of pollution and integrates environmental management with production management and technical management. It is the subject of energy consumption, material consumption, and discharge indicators that do not meet design values ​​or historical best levels and actual values. Conduct technical exchanges and analysis and formulate specific management and technical solutions.
Liaoyang Petrochemical Company's self-provided thermal power plant consumes 1.5 million tons of coal each year. In order to reduce coal consumption, Liaoyang Petrochemical Company has changed its previous method of tonnage procurement by tender to settle the calorific value, establish a complete set of coal calorific value detection methods before the furnace, and establish a purchase and sales alliance with large state-owned coal mines to form the main channel for supply. Under the conditions of open tendering, the past 29 coal suppliers were reduced to nine. Due to the change in the coal procurement model, the “multiple birds with one stone†effect was generated, which not only reduced operating costs and commercial risks, but also resulted in a significant increase in the quality of incoming coal, and due to the decline of ash, equipment wear was reduced. The failure rate of the furnace and the standby power rate of the plant have dropped significantly, and the environmental pressure of the fly ash disposal has also been greatly eased. Only this one, the whole company can reduce coal consumption by 120,000 tons per year, reduce 180,000 tons of fly ash and reduce electricity consumption by 4.352 million kwh.
At the same time, Liaoyang Petrochemical Company increased investment in terminal management, arranged 446 million yuan of funds, implemented 14 major environmental protection potential treatment projects such as thermal power plant boiler flue gas desulfurization and 440 sewage treatment plant pretreatment, and reduced pollutants. External emissions have increased the level of compliance. It invested in the construction of a number of gas recovery tanks and other recycling facilities to maximize the recovery of tail gas such as ethylene and liquid ammonia. Liaoyang Petrochemical Company also introduced part of the domestic sewage in the social area into the company's sewage treatment plant for biochemical treatment, and improved the social environment.
