Latest Patents

Among his latest patents, McKenna has developed a process for the conversion of hydrocarbons to carbon dioxide and electrical power. This process involves subjecting a gas mixture of a hydrocarbon feed stream and steam to an integrated reforming process. The stages include steam reforming in a gas-heated reformer and secondary reforming to generate a reformed gas mixture. The hydrogen content of the reformed gas mixture is increased by subjecting it to one or more water-gas-shift stages. The resulting hydrogen-enriched reformed gas is cooled, and condensed water is separated. This gas is then passed through stages of carbon dioxide separation to recover carbon dioxide. The remaining hydrogen-containing fuel stream is combusted with an oxygen-containing gas in a gas turbine to generate electrical power. The exhaust gas mixture from the gas turbine is directed to a heat recovery steam generation system, which feeds one or more steam turbines to generate additional electrical power.

Another significant patent focuses on reducing CO2 emissions from combined cycle power generation processes utilizing a gaseous hydrocarbon feed. This process splits the hydrocarbon feed into two portions, with the first portion being less than or equal to 45% by volume and the second portion being greater than or equal to 55% by volume. The first portion is fed to an autothermal reforming process to generate a hydrogen-containing gas and a carbon dioxide stream. The hydrogen-containing stream is then combined with the second portion, and the resulting hydrogen-containing fuel stream is combusted with oxygen-containing gas in a gas turbine to generate electrical power. The captured carbon dioxide stream can be fed to storage or enhanced oil recovery processes, and the process may be retrofitted into existing combined cycle processes.
