Recovery of Methane and CO 2 Sequestration

Abstract

Recovery of CBM on a commercial scale is associated with the dewatering process. The release in pressure liberates the adsorbed gas for the production. The vacant site can be utilized for the adsorption of other gases. Also the incumbent gas molecules can be displaced with a gas molecule that has more affinity towards the coal as compared to that of methane. This chapter addresses the mechanism and the produced water disposal problem associated with the CBM production. It also elaborates the measures taken in India for the management of produced water.
