浅析石化企业VOCs污染源管控与治理

Analysis on Control of VOCs Pollution Sources in Petrochemical Enterprises

近年来,国家对挥发性有机物(简称VOCs)排放监管日益严格,因此,石化企业在不断加大VOCs污染源的综合整治。石化行业生产工序多样,涉及VOCs物质组成复杂、排放环节众多,且多以无组织排放为主。设备泄漏、有机液体储存、有机液体装卸和废水收集处理系统是石化行业的主要VOCs污染源。石化行业VOCs污染源控制应遵循全过程精细化管理原则,从源头管控、过程管控和末端治理的维度开展治理。文章简要分析了石化企业VOCs污染源管控思路以及油品质量升级、储存环节采用新型接液式浮盘、提高油品装载收集效率等治理措施的应用及效果。

In recent years, the state regulation of Volatile Organic Compounds （VOCs） has become increasingly stringent. Based on the situation, petrochemical enterprises axe also intensifying the comprehensive treatment of VOCs pollution sources. However, due to the diversification of petrochemical production processes, VOCs components axe complex, coming from multiple emissions, mostly fugitive emissions difficult to control. Leaks in facilities, organic liquid storage and handling, and wastewater treatment are the major VOCs sources in petrochemical industry. VOCs source control in the industry should follow the principle of whole process refined management to control pollution at source, process and end. This paper is to analyze the applications and effects of VOCs pollution source control and technology in petrochemical enterprises, which are exemplified by the measures to upgrade oil product quality, use new-type floating plates and enhance collection efficiency in oil product handling.
