膜式气体分离已被证明是一种从天然气中脱除CO2的可靠方法，其装置的主要部分是由一种渗透膜通过特定的统制方法装配而成．因而不含任何运动部件或操作要求。与胺／甘醇吸收法相比，可显著节省投资、占地和减少设备重量，对于海上或其它边远地区，这种节省显得尤为重要。 Membrane gas separation has proven to be a reliable method of removing CO2 from natural gas, with the major part of the plant being assembled from a permeable membrane by a specific control method. It therefore does not contain any moving parts or operational requirements. Compared with the amine / glycol absorption method, significant savings in investment, land occupation and equipment weight reduction are particularly important for offshore or other remote areas.
