In China, apart from Zhenhai Refining & Chemical and CNOOC Shell which use the PO/SM process, the rest employ the chlorination process for the production of propylene oxide. It is said that the Yueyang Changlian Petrochemical Branch is currently carrying out pilot tests for the production of PO via one-step oxidation of propylene using H2O2. The main methods for producing PO are still the chlorohydrin method and the co-oxidation method. The advantage of the co-oxidation method is its lower level of pollution, but it requires large investments to produce styrene or tert-butanol on a scale that yields economic benefits. It is said that the co-oxidation plants at Zhenhai Refining & Chemical, with capacities of 285,000 tons per year for PO and 200,000 tons per year for SM, have a total investment of 4.44 billion yuan. They represent the largest chemical production facilities owned by Sinopec, and are also among the largest PO/SM production plants in the world. Is the total investment really that huge? What is the approximate investment for CNOOC Shell’s 250,000 tons per year PO/SM plant? What about PO/TBA production plants? Please, those in the know, share your thoughts. ， ， -
