 Zhonglan Yima chromium Chemistry Co., Ltd. belongs to China-Blue Star Chemical Group, is the only chromium salt production factory in Henan, was built in 1990, has more than 800 employees, 280 professional technical manpowers, the total assets is 60 million yuan, contains 200 thousand square meters. The main products are: sodium dichromate production capacity is 13 thousand ton; chromic anhydride production capacity is 4 thousand ton; potassium dichromate annual production capacity is 10 thousand ton; chromium oxide green annual production capacity is 2 thousand ton; desulfurizer production capacity is 6 thousand ton. The company annual production value is more than 120 million yuan, pay tax is about 30 million yuan. Chromic anhydride and sodium dichromate which belongs to chemical Ⅰ kind product, can be used in chemical, tannage, plating, pigment and chromic salt series products deep-processing industries, they have widely purpose.
The company abuts on Longhai Railway and No.310 National Highway, has convenient traffic, abundant  technology power, advanced technological equipments, complete detect measures, the products quality obtain GB/T1611-2003 first quality standard, The “Zhongge” brand sodium dichromate has been cognizance as “Henan exemption from inspection product” by Henan Technology Supervise Ministry, is well sold in more than twenty provinces, Cities and areas in our country. The company has been cognizance as “AAA” grade corporation by National corporation visualize cognizance committee, and be chosen as “Honoring Contract & Keeping Credit” corporation many times.
At present, our company will build one hundred thousand ton potassium dichromate item, it is the Chinese Academy Sciences “Nine Five” important task “chromium chemical industry clean produce technology” taken on by Institute of Process Engineering, Chinese Academy Sciences. As our country serious pollution industry apply green renew integrated technology first industrial implement, it brings strong reaction in local government, industry and academe is considered as “ industry revolution” which breaks through existing technology both here and abroad. Developed low temperature sub-molten salt liquid phase oxidation- reaction/separate coupling  strengthen-medium regeneration cycle-resource complete set different depth utilize chromium chemical industry clean produce integration technology realizes resource high efficiency-clean-circulatory application, improves resource-energy utilization factor, makes chromium recovery increasing to 99% from 75%, reacgion temperature decreasing to 900℃ form 1200℃, energy consumption declining 30%, and first realizes zero release in chromium chemical production both at home and abroad, technical economy, environmental criteria arrives international level. Considered form corporation long-term development stratagem, it is in favor of improve corporation competitive power and venture resistant power.
Chromium salt series products has wide purpose, is mainly used in chemical, light industry, metallurgy, weave, printing and dyeing, mechanism, instrument, hardware for daily use, tannage, medicine, building materials, and woodcraft industries, it makes important effect in national economy, and demos life. According to statistics, 15% products in national economy is correlative to chromium salt, especially, with the domestic economy fast increase in recent years, chromium salt market demand increases day by day, as a result, the corporation has wide development foreground.
The company is located in central plains, abuts on Longhai Railway, connects high speed road and No.310 National Highway, has convenient traffic, regionally competitive advantage of short delivery cycle and cheap transport costs, huge steady sales network and client group, strengthen and support technology development equipment and industrialization, improve technology level, saving energy, increase corporation economic benefit and close to international advanced stage.
