摘要：
The supersonic cyclone separation technology for natural gas has the advantages of simple and compact structures, no rotating components, high reliability, no chemical additives, low investment and maintenance costs, etc., and its industrial application prospect is broad. Due to its complex process, however, its theoretical research is not mature yet. In this paper, a series of investigation were conducted on this technology to promote its large-scale industrial application. First, the structure and working principle of a natural gas supersonic cyclone separator were introduced. Then, the latest progress of numerical simulation on its cyclone flow process, internal condensation process and internal flow process was described. Finally, the related experimental research status at home and abroad in recent years was analyzed, and the progress in numerical simulation and experimental research was summarized. Furthermore, the key issues were discussed related to the development of natural-gas supersonic cyclone separation technology in the future that need to be solved urgently. And the following research results were obtained. First, current numerical simulation researches on the supersonic cyclone separators mainly focus on its cyclone flow process, internal condensation process and internal flow process, and have obtained some achievements. Second, domestic experimental researches on the supersonic cyclone separators mainly focus on low-pressure experiments and fall behind in terms of condensation mechanism and separation mechanism of high-pressure natural gas. The following conclusions were reached. First, the curve match between the shrinkage section and the expansion section of supersonic jet and the structurally optimal design and installation position of cyclone are beneficial to gas condensation and gas-liquid separating efficiency improvement. Second, the high-pressure experiment in line with the actual working conditions of natural gas helps to explore the condensation and separation mechanisms of cyclonic gas separation. Third, it is in urgent need to carry out a thorough study to reveal the condensation mechanism and separation process of water and heavy hydrocarbons during the transonic flow of high-pressure natural gas and determine the factors influencing separation performance, so as to provide a theoretical basis for the engineering design and application of natural-gas cyclone separators. © 2018, Natural Gas Industry Journal Agency.
