Honeywell UOP announced that Oriental Energy will utilize its C3 Oleflex technology for a fourth propane dehydrogenation (PDH) unit in China. The unit, being built in Maoming, Guangdong, will produce polymer-grade propylene and is scheduled to start-up in 2022. Oriental previously licensed three C3 Oleflex units, each with 660 kta of capacity. Two are in operation, with the third expected to begin production this year. In 2017, Honeywell UOP and Oriental signed a memorandum of understanding to cooperate on five new PDH projects in China, with a combined total production capacity of 3 mta of propylene. They were to be located along with coastal cities, including Ningbo and Lianyungang.
