Hydrate process for CO2 capture from fuel gas

Increased emission of carbon dioxide (CO2) from the combustion of fossil fuels has created the global challenge of climate change. Reduction and/or elimination of CO2 emission is a mitigation strategy in the absence of a global non-carbon energy system. The capture of carbon prior to combustion and its subsequent safe storage or utilization is an opportunity to be exploited for the implementation of a successful emissions reduction/elimination strategy. The formation of gas hydrate crystals has been demonstrated in the lab to be able to capture and separate of CO2 in a simple and robust manner. When gas hydrate crystals are formed from a CO2/H2 gas mixture at suitable pressure and temperature conditions the gas hydrate crystal phase is enriched with CO2 and the remaining gas (“unreacted” gas) is enriched in H2. For example Figure 1 shows relevant data obtained in our lab. It is also noted that 42.5 and 36.1 % of the CO2 in the feed gas mixture was recovered as hydrate. Suitable additives may be included in the formation system and improve the separation. TO BE CONT’D
