1、浙江工业大学硕士学位论文炼油厂恶臭污染物治理技术研究姓名:何永纪申请学位级别:硕士专业:化学工程指导教师:黄立维20050901浙江工业大学研究生学位论文炼油厂恶臭污染物治理技术研究摘要本文通过对炼油厂各种工况下恶臭污染物排放现状的调查分析,找出在炼油加工过程中排放的恶臭污染物种类、排放量及对周围环境的影响程度,对固体吸附法、液相转化法和生物法三类恶臭污染物治理技术进行了实验室试验、现场小试的应用研究,获得了一系列实验数据,指出了存在的问题,对进一步开展炼油恶臭污染治理研究工作提供了借鉴。研究认为:(1)负载碱性金属及过渡金属氧化物的吸附剂A和带有活性物质和催化剂的吸附剂B双塔串联
2、使用,对脱除硫化氢、硫醇等硫化物有较好效果,硫容可达14%以上。(2)在炼化装置恶臭较严重的部位停工吹扫前使用专用的液相转化脱臭剂浸泡处理,能起到明显的除臭作用。(3)采用适当的预处理措施和两级生物塔串联的生物滤床技术处理组分复杂的石化污水处理废气,主要恶臭污染物的去除率为:H2S>_97.2%,有机硫化物兰87.2%,苯系物>93.7%。且在一定浓度范围内,对废气浓度变化的适应性好。关键词:炼油厂,恶臭污染,恶臭调查,恶臭治理技术II浙江工业大学研究生学位论文StudytheOdorPollutionGovernmentTechnologyintheOilPlantThisart
