摘要
在满足特定排放法规要求的前提下,经济性能指标往往会成为选择合适油气回收处理工艺的关键。通过对基于吸附法的油气回收工艺流程进行系统的对比分析,揭示了吸附/吸收组合工艺是目前世界范围内的主流技术方案,吸附/冷凝组合、吸收/膜/吸附组合等变型工艺仅在某些特定场合才得以使用。干式螺杆真空泵吸附/吸收组合工艺因其流程相对简单、占地面积较小,将会逐步取代目前仍在广泛使用的液环式真空泵吸附/吸收组合工艺。
When comparing and selecting different technologies for oil vapor recovery applications, cost is usually the most critical parameter if all candidates can meet the emission requirement. This article compares different adsorption based oil vapor recovery schemes, and concludes that the adsorption/absorption combination scheme is still the mainstream worldwide. The variations of this scheme, such as the adsorption/refrigeration combination, the absorption/membrane separation/ adsorption combination,are only used under some special scenarios. Due to its relatively simple procedure and less space requirements,the combined adsorption/absorption scheme with dry screw vacuum pump will gradually replace the widely used combined adsorption/absorption scheme with liquid ring vacuum pump. Thus,fundamental research in this area is recommended for domestic institutions having interests in the oil vapor recovery market.
