| 摘 要： | 通过分析MDEA脱硫溶液吸收选择性的影响因素,确定了气液比和塔板数为工艺调整的主要手段。通过增大装置气液比,降低胺液循环量和吸收塔塔板数,可提高胺液对H2S的选择性吸收性能,增加产品气收率,减少装置的电力、蒸汽及胺液消耗。

| Abstract: | By analyzing the influence factors of selective absorption about MDEA desulfurization, it was identified that adjusting gas-liquid volume ratio and absorber plate numbers were the main optimization methods of the process. By increasing the gas-liquid volume ratio, reducing amine circulation flow and the numbers of absorber plate, the selective absorption performance of amine could be improved. As the results, the product gas yield could be increased, and the consumption of electricity, steam and amine could be reduced. |
