Exploring the Process of Removing Acidic Gas from Natural Gas on Offshore Platforms
As a clean and efficient energy source,natural gas occupies an important position in the global energy structure.On offshore platforms,the removal of acid gas from natural gas is an essential part of the production process.A comprehensive overview of three natural gas purification schemes,namely alkanolamine process,semi-lean solution process,and membrane separation combined with alkanolamine process(multi method combined process),was conducted.The comparison was made from energy consumption and economic efficiency,process complexity,and offshore platform adaptability,and the possibility of using them for removing acidic gas on offshore platforms was systematically analyzed.The results show that the multiple process has a low cost per unit flow for separation,minimal total equipment footprint,reduced tower height,minimal alcohol amine solution circulation,and low energy consumption,making it suitable for natural gas removal of acidic gas on offshore platforms.The results suggest that the research results can provide theoretical support and practical guidance for improving the effectiveness of removing acidic gas from natural gas on offshore platforms.
