设计说明本设计对焦炉煤气的处理采用半负压操作系统，煤气的初冷采用的是横管式间接初冷器。首先，概述了煤气初步冷却的目的意义，介绍了鼓风冷凝工段的工艺流程，常用的初冷工艺及工艺流程中的常用设备，并对鼓冷工段进行了物料衡算和热量衡算。通过热量衡算和物料衡算确定了设备的选型。其次，采用喷淋式饱和器生产硫酸铵的工艺，并以饱和器母液生产粗轻吡啶最后，对脱硫和苯回收工艺作说明。同时也对介绍了用硫酸法吸收氨制取硫酸铵的工艺，并对硫酸吸收氨的工艺原理及注意事项做了一些说明，以及对硫酸铵生产工艺的物料衡算和热量衡算，硫酸铵生产的主设备及辅助设备的设计计算。回收轻吡啶的中和器的物料衡算也进行了相应的设计。关键词：横管式初冷器 物料衡算 硫酸铵 饱和器Design descriptionIn this design, the coke oven gas treatment using a vacuum operating system, the gas primary cooling is used in horizontal pipe type indirect cooling device. First, an overview of the gas primary cooling purpose and meaning, introduced the blast condensation process flow, commonly used primary cooling process and process used in the equipment, and the drum cooling section for the material balance and heat balance. By heat balance and material balance calculation to determine the selection of equipment. Secondly, using the spray type saturator for ammonium sulfate production process, and to the saturator liquor production of light pyridine. Finally, on the desulfurization and benzene recovery process for. At the same time also introduced by sulfuric acid method for preparing ammonium sulfate of ammonia absorption process, and the sulfuric acid to absorb ammonia process principle and matters needing attention are described, as well as for ammonium sulfate production process of the material balance and heat balance, ammonium sulfate production of main equipment and auxiliary equipment design. Recovery of pyridine neutralizer material balance has also ma...
