四川理工学院毕业设计 9万吨/年合成氨合成工段工艺设计 四川理工学院材料与化学工程学院 摘 要 氨是最为重要的基础化工产品之一，其产量居各种化工产品的首位。氨主要用于农业,合成氨是氮肥工业的基础。氨的合成主要有脱硫、转化、净化、合成几个工段。合成氨合成工段的设计，原料采用氮气和氢气，以合成塔为主要设备，在氨冷器、水冷器、气—气交换器、循环机、分离器、冷凝塔等辅助设备的作用下制得液氨，工艺条件为： A201为催化剂， 480℃，31Mpa。 关键词：合成 工艺参数 衡算 设备计算 -Ⅰ- ABSTR Ammonia is one of the most important basic chemical products in the world，Its output of various kinds of chemicals rank first in the world. Ammonia mainly used in agriculture and synthetic ammonia is the basis of nitrogen fertilizer industry. Ammonia synthesis is mainly from the four sections of desulphurization, conversion, decontamination, and synthesis. With using nitrogen and hydrogen as materials and synthesis converter as main equipment, under the action of the auxiliary equipments of ammonia air conditioning, water-cooling device,?gas to gas exchanger, circulator, separator, and condenser and so on, in the end, the?design?of the ammonia?synthesis section?makes ammoniacalliquor, The process conditions are determined as following:A201 as catalyst, 480℃，31Mpa .The design is be designed to material balance, heat balance and calculation of Devices type.
