ABSTRACT:
A process and apparatus for removing an impurity from a gas by means of selective absorption of a gas impurity by a suitable absorbent. The absorbent and gas are contacted in a contacting zone which is divided into a plurality of compartments with the absorbent and gas flowing cocurrently in each individual compartment. The overall system, however, is a countercurrent flow system wherein the absorbent flows downwardly and the gas flows upwardly. The process and the apparatus can be used for the removal of carbon dioxide from natural gas with the use of salt water as the absorbent. The invention is especially useful for a natural gas well located in offshore waters that produces a gas with a high concentration of carbon dioxide as the apparatus can be erected on the ocean floor and use the surrounding sea water as absorbent.
