伴生气轻烃回收工艺技术

Recovery Technology of Light Hydrocarbon in Accompanying Gas

油气田存在丰富的伴生气资源。为了提高油气综合利用水平 ,开展伴生气轻烃回收工艺技术研究有十分重要的现实意义。针对工艺流程设计、设备选型和控制系统设计进行分析与探讨后指出 ,在工艺设计中应正确选用制冷工艺 ,精心组织工艺流程 ,合理利用外冷和内冷 ;设备选型应体现技术先进和高效的原则 ;小型浅冷装置的控制方案应着重简单实用 。

After analysis and discussion the article points out choosing refrigeration technology correctly,orgnizing process flow with the best of care and utilizing outer and inner cooling reasonably.In type\|selecting of equipment it should reflect advanced in technology and high efficiency.The control scheme of small sized shallow refrigeration should be simple and practical.In large and medium sized cryogenic system,advanced collecting scattering control system should be shosen.
