近年来,由于石油和天然气的化学加工和合成技术的发展,炼焦化学产品受到竞争。粗苯为中间体产品,本身用途极为有限,仅作为溶剂使用,但是精制后的苯、甲苯、二甲苯等产品,是有机化工、医药和农药等的重要原料,在国内、国际上都有很好的市场,目前精苯产品价格持续上涨,市场潜力巨大,因此粗苯精制回收工艺很有意义。本设计主要介绍粗苯精制得到苯、甲苯、二甲苯工艺路线以及主要设备的计算与选型。
In recent years, due to the development of chemical processing and synthesis of oil and natural gas, coking chemical products are subject to competition. Crude benzol as intermediate products, itself uses extremely limited, only used as the solvent, but refined benzene, toluene, xylene and other products is an important raw material for organic chemical industry, medicine and pesticide, in the domestic and international has a good market, the refined benzene product prices continued to rise, market potential is tremendous, so crude benzol refining recovery process is of great significance. This design mainly introduces crude benzene, toluene, xylene process and main equipment selection and calculation.
