Indeed our knowledge and technical support is provided by experts drawing upon over 50 years of global industry experience. PRODUCTION OF Consequently, acrylonitrile is formed more rapidly than CO 2 and N 2 under the optimized reaction conditions (approximately 1.5 atm and 450°C). The competitor scrapped its own expansion plans and took a license from Sohio. The various processes are used are described thereafter. 0000044093 00000 n PROCESS ECONOMICS PROGRAM SRI INTERNATIONAL Menlo Park, California 94025 Abstract Process Economics Program Report No. Other acrylonitrile producers soon became licensees of the Sohio process, and within a few years, acetylene-based acrylonitrile production had been replaced by the Sohio process. The process and emissions are not significantly different. The authors based on the Sohio process, as well as on technologies employed industrially in compound syn-thesis and the purification processes involved, to develop a plant with a capacity of 120,000 t/year of acrylonitrile that would be used in the manufacture of polymers. 0000008213 00000 n The supplement of the publication manuscript contains the following information: First, the climate CO Meeting the ambitious Paris Climate Conference targets means that significant and rapid reductions of 2] ]]. 0000003808 00000 n 200 tons/day of acrylonitrile and we have adopted Sohio process as the project task.
