The Refining Company Ethylbenzene/Styrene Project Technical Solutions

Styrene is an important basic organic materials, mainly used for the manufacture of polystyrene resin, acrylonitrile-butadiene-styrene copolymer, styrene-butadiene-styrene block copolymer, styrene butadiene elastomer.styrene-acrylonitrile copolymer, styrene-maleic anhydride copolymer, an unsaturated polyester resin, ion exchange resin, synthetic resin coatings, and insulators and other materials, these materials manufactured in the automotive, appliance demultiplexer, textiles, building materials, light industry, toys and other industrial sectors have important uses. In addition, styrene can also be used in pharmaceuticals, dyes, pesticides and mineral processing industries, use very extensive.Yanchang Petroleum Group Refining Company production supporting device is not perfect, some resources are not rational utilization, especially3sets, Yan’an refinery the FCCU byproduct dry gas can only be used as a fuel, the remaining part can only put the torchcombustion. Ethylene in dry gas has not been effectively used, so that not only a waste of resources and economic loss, and pollute the surrounding atmosphere. Shaanxi Yanchang Petroleum Group Yan’an Refinery12million tons/year styrene project using the Dalian materialized stem valuable ethylene vinyl ethylbenzene recovery of dry gas in the air, is a good way to dry gas utilization and companies to improve an important measure of economic efficiency. Extends through the construction of the sets of devices, the refining industry chain, improve the added value of the resources to make a larger contribution to the overall economic benefits of the company, but will also reduce the pollution of the environment.Extended for Shaanxi Petroleum Refining Company of the Group Yan’an Refinery12million tons/year styrene taken technology analysis and deliberation, first introduce the background and significance of the the Refining Company styrene project construction, and then analyze the current domestic the development status of foreign styrene production process technology, styrene plant production unit at home and abroad were analyzed by comparing the selection to finalize the overall production technology refining Company Yan’an refinery12million tons/year styrene project programs.
