Approval granted for 100,000 tons/year HDI and 180,000 tons/year phosgene expansion project. Recently, the Ningxia Department of Ecology and Environment issued a notice announcing that the environmental impact assessment report for Ningxia Ruitai Technology Co., Ltd.’s 100,000 tons/year HDI and 180,000 tons/year phosgene expansion project (Phase I) has been accepted. According to the environmental impact assessment documents, the total investment estimate is 9.743 million yuan. The production capacity planned is 100,000 tons per year of HDI, 100,000 tons per year of HDI trimer, 180,000 tons per year of phosgene, with 290,000 tons per year of 30% hydrochloric acid as a by-product. The project is constructed in three phases, and this is the first phase, which will expand the annual production capacity of phosgene from 30,000 tons to 50,000 tons. Ningxia Ruitai Technology Co., Ltd. was established in 2010 as a joint-stock subsidiary founded with investment from Jiangsu Yangnong Chemical Group Co., Ltd. It is located in the Ningxia Zhongwei Industrial Park in the Ningxia Hui Autonomous Region, with a registered capital of 75 million yuan and an area of 3,000 mu. It is currently the largest state-owned enterprise to settle in Zhongwei City as part of local investment promotion efforts, and represents another key production base that Yangnong Group has developed in the western region. Ningxia Ruitai Technology Co., Ltd. has currently established facilities for the production of phosgene, methyl chloroformate, carbendazim, thiophanate-methyl, o-phenylenediamine, imidacloprid, monochloro and dichloro compounds, imidacloprid, as well as systems for the recycling of by-products from fine chemical industries. It also has capabilities for producing acetophenone, chloroformates and acid chlorides, nylon 66, as well as biochemical processing units along with the associated utility systems. Phosgene, also known as carbonyl chloride, is an important organic intermediate with numerous applications in pesticides, pharmaceuticals, engineering plastics, polyurethane materials, and military uses. At present, Ningxia Ruitai Technology Co., Ltd. has built a phosgene production facility with an annual capacity of 30,000 tons. Based on the production needs of downstream products, the phosgene produced is transported directly to these downstream facilities via pipelines; no storage facilities are used, and the phosgene is not sold externally. At present, the market demand for phosgene-derived products manufactured by Ningxia Ruitai Technology Co., Ltd. is on the rise, and the existing production capacity of 30,000 tons per year is no longer sufficient to enable full-scale production of these products; thus, there is a clear shortage in capacity. Furthermore, Ningxia Ruitai Technology Co., Ltd. is currently advancing the “5,000 tons/year chloroester expansion project,” which requires an additional supply of phosgene.
