峰峰100万吨焦化硫铵工段设计 华北科技学院毕业设计 目录 TOC \o 1-3 \h \u , principles of chemical engineering, coal coking design manual, etc. Characteristics and process of design The way to recovery the ammonia from coke oven gas is bubble type saturator method. The process is as follows: the coke oven gas of condensing section into the gas preheater first. Then contacted with sulphuric acid mother liquor and generated ammonium sulfate in the saturator. And ammonium sulfate separated by subsequent operation. The gas out of saturator is sent to the crude benzol section. Saturated selection of diameters DN5000/DN3800mm two spray saturator. Spray saturator ammonium sulfate production process, using the spray saturator, made ??of stainless steel, long life equipment, set pickling absorption, crystallization, acid, evaporation as a whole, with the gas system resistance, crystalline particles large (average diameter 0.7mm), ammonium sulfate good quality, short process, easy operation. Process design and instructions This design is composed of nine parts: The first and second part is introduction, it mainly introduces the present situation of coal coking and thiamine purpose and production method. The third part introduces the spray saturator principle of production of ammonium sulfate crystallization principles, factors and production of ammonium sulfate crystallization process. The fourth part carries on the detailed calculation on the equipment and equipment model were determined. The fifth part explains the arrangement of each part in detail. The sixth part explains civil engineering, water supply and drainage, power supply, heating and ventilation, meter project, project, equipment maintenance, etc. for details. The seventh part explains the main control index in this section, operating rules, open positions parking operation, labor capacity and job responsibility. The eighth part listed the equipment of thiamine section uniformly . The ninth part explains the d
