Abstract
Natural gas is increasingly recognized as a clean energy source due to its high quality,low pollution levels,and abundant availability.However,certain gas fields contain complex components that require purification for efficient transportation and utilization.Addressing these issues involves efficient gas-liquid separation technology.Existing gas-liquid separation units face challenges such as efficiency,liquid entrainment,energy consumption,and the need for consumable replacement.This study focuses on a novel cyclone-coalescence separator that combines centrifugal and coalescence principles.Imple-mented in a high-acid natural gas purification plant in China,the cyclone-coalescence separator demonstrated efficiency primarily influenced by gas velocity and diameter.Optimal performance was observed with a 75 mm diameter reactor at velocities of 8-12 m·s-1,achieving a peak efficiency of 96％.The hydrophilic glass fiber with a monofilament structure can coalesce droplets effectively.In practical industrial use,under operational conditions,the hydrocyclone's liquid discharge rate is 89.6 kg·h 1 with an inlet concentration of 382.7 g·m3.Over a 400-h cycle,the cyclone-coalescence separator demon-strated superior separation performance with an average liquid discharge volume of 9.09 mg·kg-1,compared to 4.93 mg·kg-1 for the precision filter.This successful industrial implementation presents a promising approach to natural gas purification.
