.设计总说明甲醇是一种非常重要化工原料，工业应用非常广泛。国内甲醇的需求量逐年增大，针对我国贫油少气的能源现状，煤制甲醇生产工艺充分利用了我国煤炭资源丰富的优势，近年来在国内得到了广泛应用。通过查阅资料及分析，本设计采用 Lurgi 低压法合成甲醇，以长焰煤煤作为原料，进行年产 60 万吨的煤制甲醇初步工艺设计，包括煤的选用、原料气制备工艺的设计、原料气的变换及净化工艺设计，合成工艺设计以及粗甲醇的精制工艺设计，并绘制了工艺流程图。同时，进行了物料衡算，对气化工段和合成塔进行了热量衡算。设计了甲醇合成塔和预精馏塔，并绘制出相应的设备简图。关 键 词 ： 德 士 古 气 化 炉 ， 鲁 奇 低 压 法 ， 甲 醇 ， 设 计..Design DescriptionMethanol isa very importantchemicalraw material,which iswidelyused inindustrial applications. The demand for the domestic methanol increased year by year,in view of the current situation of our country less oil and less gas in the energy, coalto methanol productionprocessmakes fulluse of the advantageof abundantcoalresources in our country, in recent years in domestic has been widely used.By means of data and analysis, the design uses Lurgi low-pressure synthesis toproduce methanol,takinglong flame coal as raw material,designingpreliminaryprocess of the coal to methanol with the annual output of 600000 tons ,Including theselection of coal, raw material gas preparation process design, raw gas transformationand purification process design, synthesis process design and crude methanol refiningprocess design, and drawing the process flow chart.At the same time, it finished thematerial balance calculation, the heat value calculation of the gasification process andtheSynthetictower .itcompletedthedesignof themethanolsynthesisreactoranddistillation distillation tower, finally drawed the corresponding diagram of equipment.Keyword： Texacogasifier,Lurgilowpressure, methanol, design..目 录1 绪论........
