PDH Project with Investment over 10 billion yuan Settled in Dongying, Shandong Province


Recently, China Zhenhua propane dehydrogenation and propylene oxide project is under pile foundation construction, which is the second 10 billion level investment project settled in Dongying Port this year. After the project is completed, it will produce 1 million tons of propane dehydrogenation to propylene and 450000 tons of propylene oxide. The comprehensive energy consumption of the project is only 161300 tons of coal, and the project has been successfully approved the EIA and EIA procedures.


Construction unit:


Zhenhua Petrochemical Co., Ltd.


Construction site:


Located in Dongying Port chemical industry park, west of Gangxi 2nd Road and north of Haixiang road.


Main works:


A set of 250000 T / a gas separation unit will be built, with an annual processing capacity of 250000 tons, including depropanizer, deethanizer, propylene and propane separation tower and other equipment


A 1 million T / a propane dehydrogenation unit with an annual processing capacity of 1 million tons is newly built, including reactor, deethanizer, deethanizer stabilizer, propane propylene separator, SHP reactor, cold box, compressor, cooler, etc.


A new PO / SM combined unit and a set of PO / SM combined unit will be built, with an annual production of 280000 tons of propylene oxide and 600000 tons of styrene, including alkylation reactor, gas phase alkylation reactor, liquid phase alkylation reactor, anti alkylation reactor, oxidation reactor, epoxidation reactor, dehydration reactor, hydrogenation reactor and other equipment


New 200 kt / a maleic anhydride plant and two sets of 5 × 20000 t / a maleic anhydride plants will be constructed, and the design scale of a single maleic anhydride plant is 100000 t / A. Each set of maleic anhydride plant is equipped with two 50000 T / a oxidation reaction units. The materials of the two oxidation reaction units are combined and then enter the subsequent absorption, desorption and product refining units, including oxidation reactor, absorption tower, product tower, analysis tower, tail gas washing tower, flaker, jet pump condensate tank, flash tank, etc.


A 90000nm / HPSA unit will be built, and a 90000nm * / HPSA unit will be built with a production scale of 90000nm / h, including adsorption tower, desorbed buffer tank, feed gas separation tank, forward discharge tank, desorption compressor and other equipment


The main products of the project include:
Polymerization grade propylene, maleic anhydride, styrene, propylene oxide, by-products are C4 light hydrocarbons, light aromatics, dry gas, fuel oil, etc.
