In recent years, as the world’s oil prices continue to rise and China’s oil dependence on foreign countries continues to increase, the traditional production methods for naphtha cracking to produce olefins face great challenges. Experts at the meeting believe that this challenge provides a broad space for the development of coal-to-olefins and can stimulate the extension and development of the downstream industrial chain of coal chemical industry. At present, we should give full play to the resource advantages of coal-based polyolefins, overcome and solve the problems of low added value of coal-based polyolefin products, inadequate utilization of by-products during the production process, and “three wastes†and effectively grasp the development opportunities of the coal-to-olefins industry.
It is reported that at present, the production of coal-based polyolefins in China is mainly concentrated in Shenhua Baotou, Shenhua Ning Coal and Datang Duolun and other companies, with a total annual production capacity of 1.56 million tons/year, of which polyethylene is 300,000 tons/year and polypropylene 126 10,000 tons/year, accounting for 6.9% of the total polyolefin production capacity in the country. Shenhua Huaning Coal Co., Ltd. and Shenhua Baotou Co., Ltd. have successfully developed polypropylene 2500H, K1102, L5E89, polyethylene DMDA8007 and other products, and are gradually forming a three-footed market structure with petroleum-based polyolefins from PetroChina and Sinopec.
SZL series biomass-fired steam boiler is package or shop-assembled water tube boiler with double steam drum and chain grate stoker structure. 4-6 tph boiler is package boiler and 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment. The former part of boiler body is surrounded by membrane wall, its upper part connects with boiler drum and lower part connects with header, which forms a combustion chamber to absorb the radiated heat from furnace; there are dense convection tube bundle between the back side of upper and lower drum, the high temperature smoke enters a separate economizer after flushing heat absorbing surface then discharge from chimney.
