摘要

本文介绍了使用物理溶剂碳酸丙烯酯从现有或新建的氢气工厂(SMR, ATR或POX)中去除二氧化碳,并将二氧化碳回收用于碳封存或EOR生产蓝氢。处理单元位于移位反应器的下游和传统PSA的上游。捕获的二氧化碳流将有足够的二氧化碳纯度用于废水或其他工业用途。本文介绍了二氧化碳去除水平、捕获的二氧化碳纯度、总公用事业消耗和该工艺的其他好处。结果将与传统的胺基CO2去除系统进行比较。

A Physical Solvent Approach to Blue Hydrogen
This paper describes the use of a physical solvent, propylene carbonate, to remove CO2 from existing or new build-Hydrogen Plants (SMR, ATR, or POX) and recovery of that CO2 for carbon sequestration or EOR to produce Blue Hydrogen. The treatment unit is located downstream of the shift reactors and upstream of a conventional PSA. The captured CO2 stream will have sufficient CO2 purity for sequestion or other industrial uses. This paper presents CO2 removal levels, captured CO2 purity, total utilities consumption and other benefits of the process. The results will be compared to a conventional amine-based CO2 removal system.
