PROCESS FOR THE PRODUCTION OF SYNTHESIS GAS
A process for producing synthesis gas, the process comprising the steps of a) reforming a hydrocarbon feed in a reforming section thereby obtaining a synthesis gas comprising CH4, CO, CO2, H2 and H2O and impurities comprising ammonia;b) shifting the synthesis gas in a shift section comprising one or more shift steps in series to a shifted synthesis gas; c) separating from the shifted synthesis gas a process condensate originating from cooling and optionally washing of the shifted synthesis gas;d) passing the process condensate to a condensate steam stripper, wherein dissolved shift byproducts comprising ammonia, methanol and amines formed during shifting the synthesis gas are stripped out of the process condensate using steam resulting in a stripper steam stream, e) adding a part of the stripper steam stream from the process condensate steam strip-per to the hydrocarbon feed and/or to the synthesis gas downstream the reforming section, up-stream the last shift step, wherein the remaining part of stripper steam is purged.

ENERGY AND HYDROGEN LOGISTICS
A method for transporting liquid methane includes generating electricity in plants; using the electricity to split water into hydrogen and oxygen; providing carbon dioxide; feeding the hydrogen and the carbon dioxide from step into a reactor system for producing methane, wherein this reactor system comprises a catalytic reactor cooled with boiling water; liquefying the methane so produced; transporting the liquefied methane to a place of consumption located far away; utilising the liquefied methane at the place of consumption subject to generating carbon dioxide;) separating this carbon dioxide. At the place of consumption the methane is subjected to a steam reformation for producing hydrogen, wherein carbon dioxide is generated. At least a part of the carbon dioxide generated during the steam reformation is transported back to the reactor system for producing methane.
