The 400,000-ton/year calcium carbide project will build 8 sets of 30000kVA totally enclosed calcium carbide furnaces, and supporting thousands of dust removal, furnace gas recovery and purification systems, and calcium carbide furnace gas as the fuel for the lime kiln. The technology is mature and reliable.
In 2008, Yangmei Group successively completed a number of technical and expansion projects including 90,000 tons/year of PVC supporting and 1 million DIE/year of reverse osmosis desalinated water treatment equipment. Qilu Chemical Company established a 70,000-ton/year OXO device carbonyl synthesizer with independent intellectual property rights. Fengxi Group developed and applied the “Fengxi Haichuan Catalytic Oxidation†acid gas treatment technology, breaking the foreign technology monopoly. . Yang Coal chlor-alkali company also obtained considerable economic benefits due to the convergence with the chemical, power, cement and other industries. Among them, calcium carbide slag as the main raw material of the power plant admixture, each year can save the capital required for the treatment of calcium carbide slag 4.1 million yuan, to save 80 million yuan to increase the investment in cement clinker.
Last year, with the joining of chemical companies such as Qilu Chemicals, Hebei Zhengyuan, and Qingdao Hengyuan Company, the number of chemical companies affiliated to Yangmei Group increased to 8 and the annual sales revenue reached 6.3 billion yuan, an increase of 112.84 year-on-year. %. According to the plan, Yangmei Coal Group will also merge and reorganize 3 chemical companies, build a 600,000-ton/year alcohol ammonia project in Quzhou, formulate and implement two plans for three-dimensional group gas supply and chlor-alkali chlorine product development, and complete 1.8 million tons/year of methanol. With the approval of the 600,000-ton/year olefin project, the new sales revenue of the chemical industry will reach 10 billion yuan.
Recently, six national calcium carbide industry experts, including the Deputy Secretary-General of the National Association for Calcium Carbide, Wu Lanshi, have gathered in the Yangmei Coal Group for the feasibility study report of the 400,000 tons/year calcium carbide project that the company will invest nearly 1 billion yuan. Experts believe that the project is in line with the national industrial policy. After the project is completed, it can meet the demand for calcium carbide of the chloro-alkali company polyvinyl chloride and three-dimensional group PVA (polyvinyl alcohol) and 1,4-butanediol belonging to the group company.
