    摘要： A novel steam reformer unit design, a novel hydrogen PSA unit design, a novel hydrogen/nitrogen enrichment unit design, and novel processing scheme application are presented. The result of these innovations results in re-allocating most of the total hydrogen plant CO2 emissions load to high pressure syngas stream exiting the water gas shift reactor while minimizing the CO2 emissions load from the reformer furnace flue gas. As compared to the conventional 60/40 split of total CO2 emissions in syngas/flue gas streams for steam reformer based conventional hydrogen plant designs, the present invention results in 85/15 or better CO2 split. This will permit about 85% or better of the total CO2 emissions load to be captured from the syngas stream, using the conventional, well proven and cost effective amine scrubbing technology. Such 85% or better CO2 capture is much greater than the 55% to 60% maximum possible using conventional steam reformer based hydrogen plant technology. As CO2 recovery from high pressure syngas stream is much easier and cost effective as compared to that from low pressure reformer furnace flue gases, a major cost benefit for equivalent CO2 recovery results with the present invention.

    摘要翻译： 提出了一种新型的蒸汽重整单元设计，新型氢PSA单元设计，新型氢/氮浓缩单元设计和新型加工方案应用。 这些创新的结果导致将氢气厂二氧化碳总排放量的大部分重新分配到离开水煤气变换反应器的高压合成气流中，同时最小化来自重整炉炉烟气的二氧化碳排放负荷。 与常规氢气设计设计中用于基于蒸汽重整器的合成气/烟气流中总二氧化碳排放量的常规60/40分解相比，本发明导致85/15或更好的二氧化碳分离。 这将允许从合成气流中捕获的总二氧化碳排放负荷约85％或更好，使用常规的，经过验证的和具有成本效益的胺洗涤技术。 使用常规的基于蒸汽重整器的氢气技术，这种85％或更好的二氧化碳捕获量远大于最大可能的55％至60％。 由于与来自低压重整炉烟道气相比，来自高压合成气流的二氧化碳回收更容易和成本有效，所以本发明的等效二氧化碳回收的主要成本优势。

    摘要： A method for generating CO using an off-gas as a source is provided. This method includes providing an off-gas feed stream, wherein said off-gas feed stream comprises CO2 and H2. This method also includes introducing said off-gas feed stream into a reactor, thereby producing an intermediate gas stream comprising CO and H2O. And this method includes separating said intermediate gas stream in a first separation device, thereby producing a product gas stream comprising CO.
