The environmental impact assessment of Satellite Energy's Phase III PDH/multi-carbon alcohol/hydrogen energy utilization project with a total investment of 10.2 billion yuan was approved. On May 4, Zhejiang Satellite Energy Co., Ltd.'s annual output of 40,000 tons of hydrogen/900,000 tons of propylene/800,000 tons of multi-carbon alcohol/80,000 tons of neopentyl glycol chemical new materials and hydrogen energy utilization integrated project environmental assessment approval was announced. The total investment is approximately 10.2 billion yuan. The construction site is located on the south side of Haitao Road, Dushangang Town, Pinghu City, Jiaxing City, Zhejiang Province. It mainly constructs PDH, multi-carbon alcohols, neopentyl glycol, supporting air separation, synthesis gas equipment, synthesis gas purification and other process equipment, as well as storage and transportation projects, public works, auxiliary projects, service projects and off-site projects supporting the process equipment. After the completion of the project, it will form an annual production capacity of 40,000 tons of hydrogen/900,000 tons of propylene/800,000 tons of multi-carbon alcohol new chemical materials and hydrogen energy utilization integrated projects. The products involved include propylene, hydrogen, n-butanol, isooctyl alcohol, n-butyraldehyde, isobutyraldehyde, recycled C8 mixed alcohol, recycled and refined C12 mixed alcohol, neopentyl glycol, liquid argon, sulfur, etc. Zhejiang Satellite Energy has previously built two phases of propane dehydrogenation (PDH) production capacity totaling 900,000 tons, both using UOP technology. After the completion of the third phase, the company's propane dehydrogenation (PDH) production capacity will reach 1.8 million tons/year. As a wholly-owned subsidiary of Satellite Chemical, the construction of this project will effectively solve the problem of supporting raw materials for the upstream and downstream of the Satellite Energy carbon three industry chain, improve the integration of the industrial chain, create a green low-carbon new material industry chain, and form an industrial cluster.
