The Group company actively creates a two-wheel drive scientific research model of independent innovation and open cooperation, which has injected a steady stream of power for the leapfrog development of the enterprise. In Beijing and Dongying set up a petrochemical design institute composed of masters, doctors and various experts, and has long-term cooperation with a number of universities and scientific research institutions, to build an industrial technology research and development center integrating production, learning, research and application. It has dozens of sets of core patented technologies including high-quality needle coke design process, cooperated with international cutting-edge laboratories, developed the first set of FCC catalytic slurry desolidification technology with independent patent protection technology, and jointly developed ultra-low emission technology of sulfur exhaust gas with other institutions. The self-developed circulating water electric field descaling technology realizes zero discharge of circulating water; Independent research and development of oil product import and sale integrated intelligent integrated management system, to achieve the oil product import and sale without loopholes and dead Angle control; The above independent research and development technology has obtained utility model patents. Behind each new and high technology, there is the spirit of innovation of Yatong people to overcome difficulties and never stop.

At the same time, the group company focuses on the cutting-edge technology and high-end equipment of the industry, and in-depth cooperation with international counterparts. The UOP low nitrogen burner is introduced to realize the ultra-low nitrogen and ultra-low sulfur emission in the heating furnace. The propane dehydrogenation unit in the new project is the largest monomer dehydrogenation unit in the world. It adopts the latest dehydrogenation process Oleflex from Honeywell UOP in the United States, which has the advantages of smaller hydrohydrocarbon ratio, lower energy consumption, longer catalyst operation cycle and high one-way conversion rate. The PO/SM unit adopts the largest co-oxygen production process in China, which greatly improves the production scale of a single unit, effectively overcomes the shortcomings of serious pollution and serious corrosion of the three wastes of the traditional process, and improves product diversity and economy; For the first time in China, the international advanced Danish Topso gasoline and diesel refining, upgrading, condensation reduction combined process and catalyst technology; The company took the lead in adopting internationally advanced selective gasoline hydrogenation technology, and on this basis, jointly developed the internationally leading and domestic first set of gasoline extraction desulfurization technology with the domestic key laboratory, which won the first prize of technical invention of China Petroleum and Chemical Industry Federation. Liaocheng Zhonghe Energy Company adopts American high-end equipment - revolutionary DiSep®61C electric separation technology and French Axens aromatics hydrogenation technology, needle coke production process, needle coke high-temperature calcination and other process technologies are the industry's most advanced level, reaching the domestic advanced level.
