摘要： Solvent absorption processes for separating components of an impure feed gas are disclosed. The processes involve two stages of gas-liquid contacting, namely a first, absorption stage and a second, stripping stage. In the case of a carbon dioxide (CO2)-containing methane gas as an impure feed gas, contacting, in the stripping stage, the solvent effluent from the absorption stage with a recycled vapor fraction of the solvent effluent from the stripping stage can improve the recovery and purity of not only the methane (and/or other light hydrocarbons in the impure feed gas), but also that of the CO2 contaminant gas.

摘要： One exemplary embodiment can be a stack for a separation vessel adapted to receive a fluid having one or more phases. The stack may include one or more walls surrounding a void, a packed bed positioned within the void, and a distributor positioned above the packed bed. Generally, the stack has a height greater than its width. Usually, the separation vessel further includes a base having a length greater than its height, and the height of the stack is orientated substantially perpendicular to the length of the base.
