Abstract:

This paper analyzed and summarized the research progress of compact natural gas desulfurization technology from both theoretical and applied technical perspectives, including gas-liquid mixing and mass transfer mechanisms, as well as efficient and compact gas purification equipment. On this basis, a technical approach to achieve efficient and compact natural gas desulfurization equipment was summarized. By atomizing the absorbent into micro droplets and promoting turbulent mass transfer between the droplets and natural gas, the rapid and efficient selective desulfurization process was strengthened, followed by gas-liquid separation. Furthermore, various feasible technologies suitable for compact natural gas desulfurization were systematically analyzed from three aspects: atomization technology, gas-liquid mass transfer enhancement, and gas-liquid separation technology, and related research work was prospected, providing theoretical and technical support for the design and development of compact natural gas selective desulfurization absorption equipment.
