摘要:

为降低碳捕集系统的能耗并提高碳捕集效率,利用HYSYS软件,以西南卧龙河气田茅口组气藏CCUS⁃EGR先导试验工程为基础,对MDEA+PZ碳捕集进行研究,通过敏感性分析与响应面优化法确定了最佳操作参数:贫胺液中甲基二乙醇胺(MDEA)的质量分数为26.6%,贫胺液中哌嗪(PZ)的质量分数为10.3%,贫胺液流量为70.3 m³/h,贫胺液进塔温度为25 ℃。在此条件下,单位脱碳能耗降低8.3%,CO2脱除率提高了17.0%,达到99.8%。据此,提出先一级增压后碳捕集及增加富胺液循环的碳捕集工艺优化方案,改进后系统能耗降低了11.9%。

Abstract:

To reduce the energy consumption and improve the efficiency of the carbon capture system, the methyldiethanolamine (MDEA)+piperazine (PZ)⁃based carbon capture process was studied with HYSYS based on the CCUS⁃EGR pilot test of the Maokou Formation gas reservoir in the Wolonghe Gas Field, southwestern China. The optimal operating parameters were determined by sensitivity analysis and response surface methodology (RSM) as follows: mass fraction of MDEA in the lean solution at 26.6%, mass fraction of PZ in the lean solution at 10.3%, lean amine solution flow rate at 70.3 m³/h, and the lean amine solution inlet temperature at 25 ℃. Under these conditions, specific energy consumption for CO₂ removal was reduced by 8.3%, and the CO2 removal rate was increased by 17.0%, reaching 99.8%. Accordingly, an optimized carbon capture process scheme was proposed, involving primary pressurization followed by carbon capture and the addition of lean amine solution circulation. After improvement, the system energy consumption was reduced by 11.9%.
