脱硫车间初步设计说明书.docVIP

摘 要 本设计为300万t/a焦炭焦化厂脱硫车间初步设计，采用的煤气脱硫方法为湿法脱硫的改良ADA法。本设计的目的是脱除焦炉煤气中的硫化氢，使硫化氢的浓度达到20mg/m3以下，同时要使生产出来的煤气各项指标满足要求，达到符合国家标准化工厂生产设计要求。本设计分为工艺部分和非工艺部分，工艺部分包括煤气净化,脱硫液再生及硫磺的回收，净化装置采用了脱硫塔，选用了四个脱硫塔并联同时工作，脱硫塔的塔径为3800mm，塔高为17800mm。再生部分采用了再生塔及其他一些辅助设备，再生塔的塔径为7400mm，塔高为51000mm。回收硫部分采用了戈尔膜过滤器。非工艺部分包括土建，供气，供电，采暖与通风，蒸汽与压缩空气，仪表及自动化，设备维修，环保，经济核算等。共绘制了3张图纸，分别为脱硫塔的设备图，设备布置图和工艺流程图。 关键词 焦炉煤气 脱硫 改良ADA法 Abstract The design of 3 million t/a preliminary design of coke plant desulfurization section, gas desulfurization methods for the improvement of wet desulphurization ADA law. The main task of this design is removing the hydrogen sulfide in coke oven gas, at the same time to produce the indicators meet the requirements of gas, to comply with national standard chemical plant production design requirements. This design is divided into parts and the process technology, process consists of gas purification, desulfurization of liquid regeneration and sulfur recovery and purification device adopts the desulfurization tower, chose four parallel work at the same time, the desulfurization tower desulfurization tower of the tower diameter is 3800 mm, height is 17800 mm. Regeneration part adopts the regenerator and other auxiliary equipment, the regeneration tower the tower diameter is 7400 mm, height is 66000 mm. Sulfur recycle part adopts the gore membrane filter. The process consists of civil engineering, gas supply, power supply, heating and ventilation, steam and compressed air, instrumentation and automation, equipment maintenance, environmental and economic accounting, etc. Three A0 drawings were drawn and desulfurization equipment figure, respectively, the factory layout and process flow diagram.
