Deep Cultivation of Carbon Four: Layout of high-end downstream to enhance profitability

Qixiang Tengda has been deeply involved in the C4 industry chain for many years, and is committed to "eat dry and squeeze out" all the components of C4 raw materials.

Zhang Jun, Secretary of the Board of Directors of Qi Xiang Tengda, told the research team: "After years of development, the company has built four product lines of butene, isobutene, n-butane, and isobutane, and has become the largest C4 deep processing industry base in China and even in the world

In terms of methyl ethyl ketone, Qixiang Tengda has the world's largest single methyl ethyl ketone unit, with a total production capacity of 180,000 tons per year, and the actual output is about 260,000 tons per year.

"While expanding the production capacity of methyl ethyl ketone and maleic anhydride, and consolidating the main business advantage, the company further developed the supply chain business to make up for the shortcomings of raw materials, extended the carbon four industry chain in an all-round way, and built MMA and polymethyl methacrylate ( PMMA) and other new devices

In terms of ensuring the supply of raw materials, Qixiang Tengda's headquarters and its wholly-owned subsidiary Siyuan Chemical are close to upstream companies such as Sinopec Qilu Branch and Sinopec Qingdao Refinery, and can purchase carbon four raw materials at close range

"The company's production equipment adopts a flexible design, and the product structure can be adjusted according to market conditions.

In terms of technology, the company has successively carried out more than 120 technological innovations and transformations on the methyl ethyl ketone device, forming a proprietary methyl ethyl ketone production technology, and the methyl ethyl ketone produced is superior to products in the same industry in terms of cost conversion rate and product quality

　　"In the future, the company will continue to increase R&D investment and enter the field of high-precision technology

　　Attack on carbon three: new projects have significant technical advantages

　　According to the plan, Qixiang Tengda will continue to focus on high value-added fine chemical products and cutting-edge new chemical materials while accelerating its entry into C3 and advancing the construction of new projects such as propane dehydrogenation and propylene oxide

　　"The company is building a 700,000 tons/year propane dehydrogenation project and supporting the downstream 300,000 tons/year propylene oxide project.

　　It is worth noting that the Qixiang Tengda propylene oxide project adopts the hydrogen peroxide direct oxidation method (HPPO method) production process shared by Evonik and ThyssenKrupp, which has low investment, simple process flow and high product yield.

　　In addition, Qixiang Tengda also introduced high-concentration hydrogen peroxide (HP) process technology independently owned by Evonik

　　"With these two authorizations, Qixiang Tengda's new 300,000-ton/year propylene oxide project has obtained the world's leading core technology in one fell swoop

　　The research team also learned that after the Qixiang Tengda 300,000-ton/year propylene oxide project is put into production, the production capacity can basically be digested locally in Shandong

　　Zhang Jun said that all projects are currently under active construction.
