Integrated process for reducing co2 emissions from transport and power generation

A process for hydrogen generation and carbon capture for marine applications, comprising:

• pumping a fuel and water feed from a marine vessel, producing a pressurized fuel and water feed;
• heating the pressurized fuel and water feed via a first heat exchanger using a carbon monoxide and carbon dioxide rich syngas mixture, producing a heated pressurized fuel and water feed and a cooled carbon monoxide and carbon dioxide rich syngas mixture;
• reforming the heated pressurized fuel and water feed using a fuel reformer, producing a raw syngas mixture containing hydrogen, carbon monoxide, carbon dioxide, water, and a residual amount of fuel;
• extracting the hydrogen from the raw syngas mixture using a hydrogen purifier, producing a hydrogen stream and the carbon monoxide and carbon dioxide rich syngas mixture;
• directing the hydrogen stream to a fuel cell for producing electricity;
• separating an amount of liquid from the cooled carbon monoxide and carbon dioxide rich syngas mixture using a first knockout drum, producing a dried cooled carbon monoxide and carbon dioxide rich syngas mixture and a liquid waste stream;
• feeding the dried cooled carbon monoxide and carbon dioxide rich syngas mixture and a further cooled regenerated solvent stream to an absorber to selectively transfer the carbon dioxide from the dried cooled carbon monoxide and carbon dioxide rich syngas mixture to the further cooled regenerated solvent stream, producing a carbon dioxide rich solvent stream and a carbon monoxide rich syngas mixture;
• reducing pressure of the carbon monoxide rich syngas mixture using a burner feed pressure regulator, producing a low pressure carbon monoxide rich syngas mixture;
• burning the low pressure carbon monoxide rich syngas mixture in a burner coupled to the fuel reformer to provide heat to the fuel reformer, producing an exhaust gas stream;
• heating the carbon dioxide rich solvent stream via a second heat exchanger using a regenerated solvent stream, producing a cooled regenerated solvent stream and a heated carbon dioxide rich solvent stream;
• further cooling the cooled regenerated solvent stream using a solvent trim cooler, producing the further cooled regenerated solvent stream;
• further heating the heated carbon dioxide rich solvent stream via a third heat exchanger using the exhaust gas to heat the heated carbon dioxide rich solvent stream, producing a further heated carbon dioxide rich solvent stream and a cooled exhaust gas stream;
• separating a portion of carbon dioxide from the further heated carbon dioxide rich solvent stream using a flash tank, producing the regenerated solvent stream and a carbon dioxide stream;
• condensing the carbon dioxide stream to produce a gas/liquid mixture containing gaseous carbon dioxide and liquid components;
• and
• separating the liquid components from the gas/liquid mixture using a second knockout drum, producing a vapor carbon dioxide stream for temporary storage on a marine vessel before unloading on land.
