摘要

对于高含CO

天然气脱碳，常规的半贫液脱碳工艺存在脱碳深度不足、再生能耗过高等问题。为提高脱碳精度、降低再生能耗，提出了一种新型双塔吸收半贫液脱碳工艺。利用Aspen HYSYS软件建立了新工艺流程模型，采用单因素敏感性分析，研究了胺液循环量、半贫液分流比和再生温度等关键参数对脱碳效果及再生能耗的影响，并进行了参数优化。在最优工艺参数（原料气CO

体积分数为23.5%时，胺液循环量为1195 m

，半贫液分流比为75%，再生温度为120 ℃）下，将新工艺与常规工艺进行了对比。结果表明，相比常规工艺，新工艺净化气流量增大了21.63 × 10

/d，折合经济效益为59.05 × 10

CNY/d；吸收塔、再生塔及富液闪蒸罐等装置的尺寸均大幅度减小；新工艺再生能耗和冷却能耗分别降低了4.836%和4.572%，节能效果明显。

Abstract

For the decarbonization of high CO

content natural gas

the conventional semi-lean liquid process suffers from insufficient decarbonization depth and excessively high regeneration energy consumption. To improve decarbonization accuracy and reduce regeneration energy consumption

a novel dual-tower absorption semi-lean liquid decarbonization process was proposed. A process model of the new scheme was established using Aspen HYSYS software

and a single-factor sensitivity analysis was conducted to investigate the effects of key parameters

including amine liquid circulation rate

semi-lean liquid split ratio and regeneration temperature

on decarbonization performance and regeneration energy consumption

followed by parameter optimization. Under the optimal process conditions (raw gas with CO

volume fraction of 23.5%

amine liquid circulation rate of 1195 m

semi-lean liquid split ratio of 75% and regeneration temperature of 120 ℃)

the new process was compared with the conventional process. The results show that

compared with the conventional process

the new process increases the purified gas flow by 21.63 × 10

corresponding to an economic benefit of 59.05 × 10

CNY/d. Moreover

the sizes of the absorption tower

regeneration tower and rich liquid flash tank are all significantly reduced. The regeneration and cooling energy consumption of the new process are reduced by 4.836% and 4.572%

respectively

demonstrating a notable energy-saving effect.
