Co-production of hydrogen, carbon, electricity, and carbon monoxide with carbon dioxide capture for refining of crude oil

A system comprising:

• a crude oil stream;
• a hydrocarbon processing unit configured to receive and process the crude oil stream to separate the crude oil stream into a liquid hydrocarbon stream, a first gas stream, and a first solids stream, the first solids stream comprising carbon, the first gas stream comprising hydrogen and methane;
• a pyrolysis chamber configured to receive the liquid hydrocarbon stream and a first portion of the first gas stream and expose the liquid hydrocarbon stream and the first portion of the first gas stream to heat in an absence of oxygen for conversion into a second solids stream comprising carbon and a second gas stream comprising hydrogen;
• a gas separation unit configured to receive the second gas stream from the pyrolysis chamber and separate the hydrogen from the second gas stream to produce an exhaust gas stream and a first hydrogen stream comprising at least a portion of the hydrogen from the second gas stream;
• a carbon separation unit configured to receive the second solids stream from the pyrolysis chamber and separate the carbon from the second solids stream to produce a carbon stream;
• a water stream comprising water;
• an electrolysis unit configured to receive the water stream and electrical power, the electrolysis unit configured to use the electrical power to perform electrolysis on the water stream to produce an oxygen stream comprising oxygen and a second hydrogen stream comprising hydrogen;
• a power generation unit configured to receive at least a portion of the oxygen stream from the electrolysis unit and a second portion of the carbon stream from the carbon separation unit, the power generation unit comprising a direct carbon fuel cell configured to combine the oxygen from the portion of the oxygen stream and the carbon from the portion of the carbon stream to generate power and a carbon dioxide stream comprising carbon dioxide;
• and
• a dry reforming unit configured to receive the carbon dioxide stream from the power generation unit and a second portion of the first gas stream from the hydrocarbon processing unit, the dry reforming unit configured to contact the carbon dioxide stream and the second portion of the first gas stream with a dry reforming catalyst under dry reforming conditions to form a syngas stream comprising carbon monoxide and hydrogen, wherein a first portion of the power generated by the power generation unit is provided to the electrolysis unit to perform electrolysis on the water stream, a second portion of the power generated by the power generation unit is provided to the pyrolysis chamber to expose the liquid hydrocarbon stream and the first portion of the first gas stream to heat, and a third portion of the power generated by the power generation unit is provided to the dry reforming unit to produce the dry reforming conditions.
