高效低成本VOCs回收系統(tǒng)主要用于石油化工等領(lǐng)域的有機氣體資源化回收治理。該系統(tǒng)分別采用了渦輪膨脹制冷技術(shù)和微通道深冷換熱技術(shù)。渦輪膨脹制冷技術(shù)制冷溫度低且效率高；微通道深冷技術(shù)能夠顯著提高換熱效率，在壓力僅降升高2~3倍的情況下，將Nu數(shù)提高6~8倍，回收率可達到99%以上，排放低于120mg/m3，同時可以降低系統(tǒng)能耗30%以上。

　　The efficient and low-cost VOCs recovery system is mainly used for organic gas resource recovery and treatment in fields such as petrochemicals. The system adopts both turbine expansion refrigeration technology and microchannel cryogenic heat transfer technology. Turbo expansion refrigeration technology has low refrigeration temperature and high efficiency; Microchannel cryogenic technology can significantly improve heat transfer efficiency. With only a 2-3 fold increase in pressure, the Nu number can be increased by 6-8 times, and the recovery rate can reach over 99%. The emissions are below 120mg/m3, and the system energy consumption can be reduced by more than 30%.

　　與傳統(tǒng)的回收方式相比，本系統(tǒng)具有體積小、效率高、成本低、穩(wěn)定性好等特點，且后期的運行維護成本遠低于目前同類技術(shù)。高效低成本VOCs回收系統(tǒng)的實施有望突破傳統(tǒng)回收方法適用范圍窄、回收效率低、回收成本高的技術(shù)瓶頸，為實現(xiàn)VOCs回收裝置大規(guī)模商業(yè)化應用提供可借鑒的技術(shù)基礎(chǔ)，項目實施將產(chǎn)生巨大的環(huán)境效益、經(jīng)濟效益和社會效益。主要技術(shù)指標：1. 深冷后被凈化的油氣送至預冷段做預冷用2. 吸附劑吸附率可同比提高11.7％3. 回收率最高可達到99%，高于國家標準規(guī)定的95％4. 尾氣濃度為50mg/m?，低于國家標準規(guī)定的120mg/m?5. 可實現(xiàn)冷能梯級利用

　　Compared with traditional recycling methods, this system has the characteristics of small size, high efficiency, low cost, and good stability, and the later operation and maintenance costs are much lower than current similar technologies. The implementation of an efficient and low-cost VOCs recovery system is expected to break through the technical bottlenecks of traditional recovery methods, such as narrow applicability, low recovery efficiency, and high recovery costs. It will provide a reference for the large-scale commercial application of VOCs recovery devices, and the project implementation will generate huge environmental, economic, and social benefits. Main technical indicators: 1 The purified oil and gas after deep cooling are sent to the pre cooling section for pre cooling purposes The adsorption rate of the adsorbent can be increased by 11.7% year-on-year The highest recovery rate can reach 99%, which is higher than the national standard of 95% Is the exhaust concentration 50mg/m? Is it lower than the national standard of 120mg/m? 5. It can achieve cascade utilization of cold energy
