摘要
Abstract
To address the frequent flooding issue in the absorption tower of a desulfurization and decarbonization unit of a natural gas processing plant in Northwest China,this study accurately identified through multiple on-site control experiments that the core factor inducing flooding is the synergistic increase in feed gas temperature and flow rate,rather than amine solution foaming or equipment design defects.Through experiments including adjusting amine circulation rate,coordinated/independent control of feed gas temperature and flow rate,control of lean amine inlet temperature,and monitoring of feed gas composition changes,and after multi-scheme technical and economic comparison,an innovative physical defoaming scheme was proposed by installing stainless steel Pall ring packing at the bottom of the absorption tower.After implementation,the average pressure drop of the absorption tower decreased by 3.06 kPa,the defoamer injection period significantly extended from once every 3.8 days to once every 8.8 days,and the system's anti-interference capability improved by 47.6%.This study result shows that the critical impact of operating parameter fluctuations on flooding.The scheme successfully resolves the flooding bottleneck with low operating cost and significant benefits.The research results provide theoretical basis and technical solutions for process optimization and equipment retrofitting of sour gas desulfurization and decarbonization units.关键词
