China Drying Newsletter Liaohe Petrochemical Company adheres to the fine-quality route and high-end route in asphalt production, and has become the most widely used domestic asphalt in China's airport construction. As of December 23, of the 39 airports that have asphalt concrete runways in China, 18 airports use the "Kunlun - Huanxiling" brand airport asphalt produced by this company, accounting for about half of the airport asphalt market.
In all road constructions, airport runway material requirements are the most stringent. Airport asphalt must have good elasticity, impact resistance, high temperature resistance and anti-aging properties. Before 2000, more than 95% of airports in China that used asphalt pavements used products from internationally renowned companies such as Shell. "Domestic asphalt cannot compete with foreign brands in the high-end market" has become the view of many people in the industry.
Accelerate access to the high-end market of the airport asphalt market, establish self-confidence in the national brand, Liaohe Petrochemical seizes the favorable opportunity for speeding up the construction of the airport in China, uses well the heavy oil and heavy oil resources, takes R&D and technology as fulcrums, and depends on scientific and technological progress to promote the continuous quality of asphalt products. upgrade.
Raw materials are the basis. Liaohe Petrochemical has always used crude oil from Liaohe Oilfield as raw material for bitumen production. With the increase in the amount of imported crude oil, the imported oil, which is different from the Liaohe low-sulfur crude oil, has brought difficulties to the operation of the Liaohe petrochemical plant. Liaohe Petrochemical has screened 17 crude oils from 7 countries including Canada and Australia, optimized the raw material mix, and eased the contradictions that restrict production due to large differences in crude oil quality. In addition, the company expanded the hydrogenation plant, reformed idle equipment, and put it into hydrogenation tail gas recovery facilities, which not only enhanced the desulfurization capacity of the plant, but also solved the problem of sulfur balance.
Only the raw material advantage is not enough, but also has the characteristics of science and technology as a driving force for development. The company formed different production technologies based on the properties of different crude oils, independently developed techniques such as straight-run method, semi-oxidation method, and blending method, and pioneered the modified distillation method of asphalt production, which changed the situation that super-heavy oil cannot directly produce asphalt. The world-class problem of inferior heavy oil processing.
Liaohe Petrochemical places great emphasis on the combination of production, education and research, and cooperates with more than a dozen research institutes and universities of the Ministry of Communications and the Harbin Institute of Technology to establish a research institute with the most complete test methods for asphalt research in China, providing the company with sustainable development in the high-end market. The source of power.
With its unique advantages, Liaohe Petrochemical’s airport asphalt has become increasingly famous. This year, the asphalt produced by this company was successfully applied to the runway of the first 4F flexible aircraft in China, and the heavy road asphalt was awarded the title of “China Petroleum and Chemical Industry Famous Brand Productsâ€. Dai Zheng, chief engineer of Northwest Civil Aviation Airport Construction Co., Ltd., said that the longest-running airstrips built on the "Kunlun-Joyhill" brand asphalt have been used for more than 10 years. No quality problems have been found so far.
According to the statistics of the European Asphalt Pavement Association, the proportion of asphalt pavement in airports in Europe and the United States has exceeded 60%, while this figure in China is only 21.9%. The application of airport asphalt in China is promising.
Li Tianshu, general manager of Liaohe Petrochemical Company stated that the company will seize the favorable opportunity to consolidate the research and development achievements of high-end asphalt, make efforts in high-end products and variety diversification, and build a world-class asphalt production base as soon as possible.
