Methods for producing liquid organic hydrogen carriers from plastic oil

A method for producing liquid organic hydrogen carriers from plastic oil, the method comprising:

• passing a plastic oil stream to a pre-treatment unit to generate a pretreated plastic oil stream;
• passing the pretreated plastic oil stream and an input hydrogen stream to a hydrogenation unit to form a hydrotreated effluent stream, wherein:
• the plastic oil stream comprises the liquid fraction from pyrolysis of waste plastics;
• and
• the hydrotreated effluent stream comprises saturated liquid organic hydrogen carriers, unreacted hydrogen, and byproducts;
• passing the hydrotreated effluent stream to a separator to isolate the liquid organic hydrogen carriers as an LOHC stream from the unreacted hydrogen and byproducts as a residual stream;
• passing the residual stream to a reclamation unit to recover the unreacted hydrogen as a recovered hydrogen stream from the residual stream to generate a byproducts stream, wherein the byproducts stream comprise a remainder of the residual stream upon recapture of the unreacted hydrogen;
• passing the recovered hydrogen stream to the hydrogenation unit to offset hydrogen demand from the input hydrogen stream;
• transporting the LOHC stream from a first hydrocarbon processing facility to a second hydrocarbon processing facility;
• and
• passing the LOHC stream to a dehydrogenation unit to form a dehydrogenated hydrocarbon stream and a hydrogen product stream, wherein:
• the first hydrocarbon processing facility houses at least the hydrogenation unit, the separator, and the reclamation unit;
• the second hydrocarbon processing facility houses at least the dehydrogenation unit;
• and
• the first hydrocarbon processing facility and the second hydrocarbon processing facility are separated by at least 100 km.
