[摘要]:本设计为年产一万吨粗苯回收工艺设计,包括工艺和非公艺两部分。
工艺部分包括工艺论证和选择,粗苯回收原理,工艺流程详述,主要设备的计算,选型和布置等。该部分是由终冷洗萘,焦油洗苯和蒸馏脱苯三部分组成,终冷部分由横管终冷塔喷洒轻质焦油洗萘,焦油洗苯,蒸馏部分用管式炉加热法加热蒸汽和富油生产一种苯--粗苯。
非公艺部分包括土建,供电供气,自动化仪表,防爆,防火投资概算和经济分析,这些都是顺利生产的必需条件。
在设计过程中,参照了陕西焦化厂焦炉煤气净化工艺,选用比较好的设备。如用塑料花填料代替木质填料,有阻力小,比表面积大,效率高。重量轻,拆卸简单易操作等优点;再有用螺旋式换热器替换列管式换热器,具有传热系数大,价格便宜等优点,节约了水量,经济效益也好,所有这些工艺的改进,不仅利于生产,而且降低了投资

This design is an annual output of ten thousand tons of crude benzol recovery process design, including process and non art in two parts.
Process section includes a technology demonstration and selection, crude benzol recovery principle, technological process, main equipment selection and calculation, layout. This is part of the final cooling naphthalene, tar benzene washing and distillation benzene removal is composed of three parts, final cooling part is composed of horizontal tube final cooling tower spray light tar naphthalene, tar washing benzene distillation section, tubular furnace for heating heating steam and rich oil production of a benzene, crude benzol.
Public arts section includes civil, air supply, automation instruments, explosion-proof, fire investment budget and economic analysis, these are the necessary conditions for smooth production.
In the design process, with reference to the Shaanxi coking plant coke oven gas purification process, use good equipment. As with plastic flower packing to replace wood filler, with little resistance, large specific surface area, high efficiency. Light weight, easy disassembly and easy operation etc.; again useful spiral heat exchanger to replace the tubular heat exchanger, the heat transfer coefficient is big, the advantages of cheap, thus saving water, economic benefits good, all of these process improvements, not only conducive to the production, but also reduces the investment
