- 摘要:
- 为了回收天然气处理厂轻烃深加工产品产生的VOCs,对油气回收工艺流程进行了研究与设计。通过处理厂内轻烃产品的日产量与苛刻环境条件下产生的VOCs量,确定油气回收装置的混合处理规模为80 m3/h。研究现有的油气回收工艺,结合挥发物中含苯的特点,提出了“冷凝+吸附”的技术方法,并应用HYSYS软件模拟了近饱和浓度VOCs的回收工艺。结果表明,该回收工艺可行,装置回收处理效率≥95,满足GB 50759-2012 《油品装载系统油气回收设施设计规范》气体排放标准要求。
To recover the VOCs produced during deep processing of light hydrocarbon in natural gas processing plant, research and design were performed for oil and gas recovery process. According to the daily output of light hydrocarbon products within the plant and the amount of VOCs in harsh conditions, it was determined that the mixed process capacity of the oil and gas recovery unit was 80 Nm3/h,. The method of condensation plus adsorption was proposed by studying existing oil and gas recovery technology with the characteristics of the benzene-containing in volatile substance. HYSYS was used to simulate the recycling technology of nearly saturated VOCs. Results showed that the recovery technology was feasible, recycling efficiency was 95% or above, and met emissions standards in GB 50759-2012 Code for Design of Vapor Recovery Facilities of Oil Products Loading System.
