本设计是以天然气为原料的年产十万吨合成氨变换工序的工艺设计，设计主要采用美国凯洛格工艺，用高-低变串联的净化合成气的工艺流程。设计分为以下几部分：第一部分主要介绍了合成氨工艺技术的现状及发展趋势，并论述了主要工序以及本设计流程的选取。第二部分介绍了氨变换工序的各种流程并确定了本设计高—低变串联的流程。第三部分进行了包括总体消耗定额计算和热量衡算以及设备的热负荷计算在内的主要工艺计算。第四部分介绍了主要设备废热锅炉的选型及工艺条件计算，从而确定了废热锅炉的各尺寸大小。最后本设计绘制了一张高变废热锅炉条件图和带控制点的工艺流程图。
The process design designing that the annual output of one hundred thousand tons of synthetic ammonia being to take gas as raw material shifts working procedure's originally, designs the process flow adopt the USA Jiluoge handicraft mainly , being changed into in-line purification syngas low with height. Design that mark is several parts of the following: Part I has introduced synthetic ammonia technology current situation and developing trend mainly , has discussed and main working procedure and choice designing technological process's originally. Part II has introduced that ammonia has shifted various working procedure technological process and have ascertained the in-line technological process designing
