油气回收技术在凝析油加工企业的应用

针对凝析油易挥发且轻质油品收率高的特点,以中海石油葫芦岛精细化工有限责任公司为例,介绍了吸附法与吸收法相结合的油气回收技术工艺流程,对技术改造后该公司的环境效果、经济效益和社会效益进行监测和分析。结果表明：油气回收技术改造后,储油库油气排放检测浓度符合GB20950-2007要求,油气回收率超过95%,尾气排放质量分数小于5g/m3;回收轻质油品100.24t,每年可产生经济效益60.14×104元,净利润55×104元;保证了装车站台的安全生产,提高了企业的清洁生产水平。

Application of oil vapor recovery technology in condensate oil processing enterprise

Condensate oil is more volatile and light oil has a high recovery rate. Taking CNOOC Huludao Fine Chemical Industry LLC as an example, this paper introduces the oil vapor recovery technology process flow with combined method of adhesion and adsorption, and carries out monitoring and analysis of environmental benefits, economic benefits and social benefits of the company after technical transformation. The results show that after technical transformation of oil vapor recovery technology, the detected concentration of oil vapor emissions complies with the requirements specified in GB20950-2007, the oil vapor recovery rate is greater than 95%, exhaust emission concentration is less than 5 g/m3, and recovered light oil is up to 100.24 t, with an annual income at 601,400 CNY and net income at 5.15 million CNY. The application of the technology provides a support to safe operation for oil loading station and improves cleaning running level for the enterprise.
