    摘要： The invention is a process involving membrane-based gas separation for separating and recovering carbon dioxide emissions from combustion processes in partially concentrated form, and then transporting the carbon dioxide and using or storing it in a confined manner without concentrating it to high purity. The process of the invention involves building up the concentration of carbon dioxide in a gas flow loop between the combustion step and a membrane separation step. A portion of the carbon dioxide-enriched gas can then be withdrawn from this loop and transported, without the need to liquefy the gas or otherwise create a high-purity stream, to a destination where it is used or confined, preferably in an environmentally benign manner.

    摘要翻译： 本发明是一种涉及膜基气体分离的方法，用于从部分浓缩形式的燃烧过程中分离和回收二氧化碳排放，然后运输二​​氧化碳并以密闭方式使用或储存，而不将其浓缩至高纯度。 本发明的方法涉及在燃烧步骤和膜分离步骤之间建立气流回路中二氧化碳的浓度。 然后可以将一部分富含二氧化碳的气体从该回路中排出并运输，而不需要将气体液化或以其它方式产生高纯度物流到其使用或限制的目的地，优选地以环境友好 方式。
