以烟气二氧化硫为原料生产单质硫工厂设计VIP免费

北京理工大学珠海学院2020届本科生毕业设计以烟气二氧化硫为原料生产单质硫工厂设计以烟气二氧化硫为原料生产单质硫工厂设计摘要由于目前二氧化硫气体污染问题日益严峻，因此本文旨在对烟气中的二氧化硫进行脱除并且制得硫磺，实现废气利用并能起到环境保护的。本文采用的是干气脱硫法一氧化碳催化还原二氧化硫制硫磺的工艺方法，共有三个系统，分别是解析后的二氧化硫气体处理系统，反应系统和产品回收系统。该法目前还未实现工业化，通过化工软件Aspen模拟为未来的工业化成为可能，使得未来烟气脱硫治理工艺更加简便，高效及安全。关键词：烟气脱硫；硫磺；一氧化碳；选择催化PlantdesignforproducingelementalsulfurfromfluegassulfurdioxideAbstractBecauseoftheseriousproblemofsulfurdioxidegaspollution,thispaperaimstoremovesulfurdioxidefromfluegasandmakesulfur,realizewastegasutilizationandenvironmentalprotection.Inthispaper,thedrygasdesulfurizationprocessofcarbonmonoxidecatalyticreductionofsulfurdioxidesulfurtosulfur,therearethreesystems,respectively,aftertheanalysisofsulfurdioxidegastreatmentsystem,reactionsystemandproductrecoverysystem.Themethodhasnotyetbeenindustrialized,andAspenplussimulationispossibleforthefutureindustrialization,whichmakesthefuturefgdprocessmoresimple,efficientandsafe.Keywords:Fluegasdesulfurization;sulfur;carbonmonoxide;selectivecatalysis目录1绪论................................................................................................................................................11.1烟气脱硫概述.....................................................................................................................11.1.1目前国内烟气脱硫状况........................................................................................11.1.2烟气脱硫的意义及目的........................................................................................11.2工艺选择.............................................................................................................................21.2.1烟气脱硫方法的分类............................................................................................21.2.2常用的脱硫技术....................................................................................................31.2.3本设计研究的基本思路和方法....................................................................................91.2.4工艺条件........................................................................................................................91.2.5研究的技术路线..........................................................................................................102物料横算....................................................................................................................................112.1气液分离器.....................................................................................................................112.2干燥塔............................................................................................................................122.3冷凝器............................................................................................................................142.4反应器............................................................................................................................153.热量衡算..................................................................................................................................163.1干燥塔......
