Abstract

A particulate material for removing an acid gas and/or mercury contaminant from a hydrocarbon gas is disclosed. The particulate material comprises a superabsorbent hydrogel comprising a cross-linked hydrophilic polymer network having from 0.1 mol % to 50 mol % cross-linking agent. The superabsorbent hydrogel has one or more compounds capable of binding the acid gas and/or mercury contaminant incorporated into the hydrophilic polymer network by absorbing said one or more compounds as a liquid phase or an aqueous solution. Methods for preparing the particulate material and using the particulate material to remove one or more acid gas and/or mercury contaminants from a hydrocarbon gas, dehydrating the hydrocarbon gas, and mitigating corrosion in gas flowlines are also disclosed.
