毕业设计说明书中文摘要

此次工艺设计目的为年产30万吨对二甲苯，采用的方法为甲苯甲醇烷基化法。所采用的方法相比于其他方法具有“产率高、污染小、成本低”的优点。设计是采用通过Aspen Plus、CUP-TOWER、Sw6等专业化工软件，对生产工艺进行模拟、设计，最终获得甲苯甲醇烷基化法年产30万吨PX生产车间设计资料。设计资料主要包括：设备材料的选取、设备选型、设备成本估算以及部分设备的设计图纸。除单个设备的设计外，还进行了热集成网络的简单说明。在完成设备设计后，还对车间布置作了简单说明。 关键词 对二甲苯 甲苯 甲醇 Aspen Plus 烷基化 毕业设计说明书外文摘要

Title The workshop design of an annual output of 300000 tons of paraxylene with alkylation of toluene with methanol method Abstract The process is designed to produce 300000 tons of paraxylene with Alkylation of toluene with methanol method. Compared with other methods, the adopted method has the advantages of higher production rate, less pollution and lower cost. Design is used by professional chemical software Aspen Plus, CUP-TOWER, Sw6 etc., on the production process of simulation, design, and ultimately won the alkylation of toluene with methanol method of annual production capacity of 3 million tons of PX production workshop design. The design material mainly includes: equipment material selection, equipment selection, equipment cost estimation and design drawings of some equipment. In addition to the design of a single device, a brief description of the thermal integration network is also carried out. After the design of the equipment, the workshop layout is simply explained.
