罐区油气挥发性有机物治理技术研究进展

Research progress of the control technology of hydrocarbon volatile organic compounds (VOCs) in a tank farm

介绍了罐区油气挥发性有机物(VOCs)的来源和危害,分别针对浮顶储罐和固定顶储罐探讨了VOCs源头治理措施,阐述了冷凝-吸附、膜-吸附、吸收-吸附等VOCs回收工艺的原理、技术特征和潜在问题。对今后罐区VOCs治理的发展模式和攻关方向进行了展望,指出了源头治理的重要性,认为VOCs末端治理技术应向信息化、自动化、撬装化、小型化、集约化、节能化、全密闭的方向发展。

The sources and hazard of hydrocarbon volatile organic compounds(VOCs)in tank farms were introduced.The source control technologies were discussed for floating-roof tank and fixed-roof tank.Several recovery technologies such as condensation-adsorption,membrane-adsorption and absorption-adsorption were analyzed from their principles,characteristics and potential problems.The future development modes and research directions of VOCs in tank farms were proposed and source treatment was emphasized.It was considered VOCs terminal treatment should develop toward to a direction of informatization,automation,skidding,miniaturization,intensification,energy saving and full sealing.
