Zhenhua Petroleum plans to build a propane dehydrogenation and propylene oxide project in Dongying. Zhenhua Petrochemical Co., Ltd. intends to construct such a project in Dongying, and the environmental impact assessment report for the project was made publicly available for the first time recently. The main construction components of this project include: 1 set of gas separation unit, 1 set of raw material refining and separation unit, 1 set of propane dehydrogenation unit, 2 sets of maleic anhydride production units, 1 set of PO/SM combined unit, 1 set of isobutane normalization unit, 1 set of PSA unit, along with the accompanying utility and environmental protection facilities. The main products of this project are polymeric-grade propylene, maleic anhydride, styrene, propylene oxide, etc., while the by-products include hydrogen, tetraalkenes, light aromatics, dry gas, fuel oil, etc.
It’s a good project; the profits from propylene are substantial. I’m not sure what the annual production capacity is in kt/a. It seems there aren’t many companies in China with high capacity for propylene production. One such company is Yue New Materials in Ningbo. I used to work there; they used 6000 cubic meter spherical tanks, 10,000 cubic meter tanks for isooctane, and there was also a low-temperature propane storage tank with a capacity of around 10,000 cubic meters. Liquefied hydrocarbon substances are extremely dangerous, and their storage volumes are very large. In the event of a major explosion, everything would be destroyed – the companies located in the chemical industrial area would definitely be blown up as well, and it’s likely that several surrounding villages would also be destroyed
On July 30, the Dongying Port Economic Development Zone in Shandong Province released a public notice regarding the disclosure of information on the first environmental impact assessment for the propane dehydrogenation and propylene oxide project carried out by Zhenhua Petrochemical Co., Ltd. The main contents of the public announcement are as follows: I. Project Overview Project Name: Propane Dehydrogenation and Propylene Oxide Project Contractor: Zhenhua Petrochemical Co., Ltd. Location: North of Gangbei First Road and West of Gangxi Second Road, Dongying Port Economic Development Zone. Construction Scope: This project involves the construction of 1 gas separation unit, 1 raw material refining and separation unit, 1 propane dehydrogenation (PDH) unit, 2 maleic anhydride units, 1 PO/SM combined unit, 1 isobutane normalization unit, 1 PSA unit, along with accompanying utility and environmental protection facilities. The main products of this project are polymeric-grade propylene, maleic anhydride, styrene, propylene oxide, etc., while the by-products include hydrogen, tetraalkenes, light aromatics, dry gas, fuel oil, etc.
Don’t make things sound scary; if you don’t understand science, don’t speculate unnecessarily.
Don’t just follow what others say! The situation in Tanggu can be found in the \"Accident Investigation Report\"; it was caused by the improper storage of chemicals.
The key is whether the propane raw material can be supplied stably The Sino-US trade war has introduced a lot of uncertainty into international trade; it’s impossible to predict what will happen – a single tweet can lead to everything coming to a halt, as was the case with soybeans and corn.
The Dongguan Juzhengyuan project seems to have started operations
I mean, if it explodes, the situation will be similar to that at the explosion site in Tanggu
