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.

Abstract: The present disclosure generally relates to thermally conductive hydrogels. In particular, the present disclosure relates to thermally conductive hydrogels comprising one or more acidic gas absorbents, which can be used to capture one or more acidic gases from gaseous streams or atmospheres. The present disclosure also relates to processes, methods, systems, uses and apparatuses comprising the thermally conductive hydrogels for capturing acidic gases from a gaseous stream or atmosphere.

Abstract: The present disclosure is to functionalised polyamine hydrogels that can be used for capturing one or more acidic gases from gaseous streams and atmospheres. In particular, the present disclosure is directed to hydrogels comprising a cross-linked polyamine or copolymer thereof, wherein the cross-linked polyamine comprises one or more amine groups substituted with an optionally substituted alkanol group. Methods and apparatuses for removing acidic gases from gaseous streams or atmospheres using the functionalised hydrogels are also disclosed.
