延迟焦化装置挥发性有机物减排探究

Study on Emission Reduction of Volatile Organic Compounds in Delayed Coking Unit

传统焦化装置石油焦的除焦、静置脱水、取焦、输送、存储及装车过程,均为开放式作业,作业期间石油焦粉尘污染与恶臭气体逸散,存在严重的职业健康和环保隐患。针对延迟焦化装置各工艺环节、现有生产设备存在的主要环保隐患,分两个阶段进行治理,有效解决该装置废气无组织排放和挥发性有机物(VOCs)散发等问题;总结环保隐患治理技术实际投运后存在的问题,对后续改进措施进行研究,以进一步推进延迟焦化装置VOCs的减排,实现人与自然的和谐共生。

The process of coking,static dehydration,coke extraction,transportation,storage and loading of petroleum coke in traditional coking units are all open operations,during which the petroleum coke dust pollution and odor gas escaping has serious occupational health and environmental protection risks.In view of the main environmental protection hazards existing in the process links and the existing production equipment of the delayed coking unit,the problems of unorganized exhaust gas discharge and emission of characteristic odor factors and volatile organic compounds(VOCs)are treated in two phases.The problems existing after launch of environmental protection hidden danger management technology are summarized,and follow-up improvement measures are studied to further promote the emission reduction of delayed coking unit VOCs,aiming to realize the harmonious coexistence of human and nature.
