Among them, the 800,000 tons/year propane dehydrogenation (PDH) unit motor-braked hydrogen expander independently developed by Hangzhou Hangoxygen Expander Company obtained the first (set) certification in China. The PDH hydrogen expansion unit is one of the indispensable key equipment for large-scale propane dehydrogenation units. Whether the unit can be successfully operated directly affects the economics of propane dehydrogenation units invested in the tens of billions. Before the successful localization of Hangzhou Oxygen Expander Company, it had been used by Europe and the United States * * Technology monopoly directly affects the safe development of my country's propylene chemical industry. As a large state-owned enterprise with strong technology and manufacturing strength, Hangyang has the responsibility and tradition to break the monopoly of international high-end equipment. Hangzhou Hangyang Expander Co., Ltd., as a wholly-owned professional expander subsidiary of Hangyang Group, has nearly 60 years of profound technology accumulation. After three years of research and development, the 800,000-ton/year propane dehydrogenation unit hydrogen turbine expander independently developed in 2021 was successfully launched in Donghua Energy Ningbo New Materials, and all technical indicators met the process requirements. During the development process, it obtained 4 authorized invention patents and 5 utility model patents. It presided over the drafting of 1 industry standard for hydrogen expanders. Experts from China Communications Association have identified that all key technical indicators have reached the international advanced level.
