摘要：丙烯是仅次于乙烯的第二大石化基础原料，可用于生产聚丙烯、丙烯腈、丁辛醇、环氧丙烷、丙烯酸及多酯等众多产品，被广泛应用于国民经济和生活的各个领域。丙烯主要通过蒸汽裂解制乙烯的联产和炼厂催化装置的干气中获得，此外丙烷脱氢和以甲醇为原料的缩合法（MTP)也是丙烯生产的重要补充。国内丙烯生产主要集中在中石化、中石油量大集团公司，初步估算2009年其丙烯产量合计约953万吨，约占全国总产量的百分之八十二。2009年我国丙烯表现消费量约为1305万吨，当量消费约为1975万吨，当量自给率仅百分之五十八。在宏观上，国内油品及乙烯原料的供应仍将是紧张的，必须开辟增产丙烯的新途径。本文针对丙烯短缺的现状，以甲醇为原料通过催化方法生产丙烯，将低附加值的甲醇转化成高经济附加值的丙烯，设计了60万吨/年能力的甲醇转化制丙烯装置。文中对甲醇制丙烯的工艺进行了选择，对主工工艺参数进行了计算，利用ASPEN PLUS软件进行了严格的物料衡算和热量衡算，并对主要设备进行了选型计算。本设计对于国内丙烯短缺现状的缓解具有一定的积极意义。57845

Abstract: Propylene is second to the ethylene petrochemical base materials, can be used in the production of polypropylene, acrylonitrile, butyl octyl alcohol, epoxy propane, acrylic acid and ester, and many other products, widely used various fields of national economy and life.Propylene mainly through pyrolysis of steam power plant and refinery dry gas of catalytic device, in addition the propane dehydrogenation and methanol as raw materials of condensation method (MTP) is also important supplement of the propylene production.Domestic propylene production mainly in the large amount of sinopec and petrochina group co., LTD., preliminary estimates the propylene yield in 2009 total of about 9.53 million tons, accounting for about eighty-two percent of the total national output.Domestic propylene production mainly in the large amount of sinopec and petrochina group co., LTD., preliminary estimates the propylene yield in 2009 total of about 9.53 million tons, accounting for about eighty-two percent of the total national output.Propylene performance of 2009, China's consumption of about 13.05 million tons, equivalent consumption of about 19.75 million tons, equivalent rate is only fifty-eight percent.In the macro level, the domestic oil and ethylene raw material supply will continue to be nervous, have to open up a new way of increasing propylene.In this paper the present situation of the shortage of propylene, using methanol as raw materials by the methods of catalytic production of propylene, the low value-added methanol into high value-added propylene, design for 600000 tons/year capacity of methanol reforming system of propylene plant.This paper has carried on the choice of the technology of methanol to propylene, held the process parameters for the calculation, using ASPEN PLUS software to carry on the strict material balance and heat balance, and the selection of main equipment.This design for the present situation of domestic propylene shortage has certain positive meaning.
