Claim 19:
20. The system of claim 15, wherein the system further comprises:
a separator fluidly connected to the hydrocracking reactor and configured to separate the hydrocracked hydrocarbon product stream into a light fraction stream comprising C1-C4 hydrocarbons, hydrogen sulfide, hydrogen, ammonia, or combinations thereof and a heavy hydrocarbon fraction stream comprising C5+ hydrocarbons;
a scrubbing unit fluidly connected to the separator and configured to separate the C1-C4 hydrocarbons and hydrogen from the hydrogen sulfide and ammonia;
a pressure swing adsorption (PSA) unit fluidly connected to the scrubbing unit and configured to separate the hydrogen from the C1-C4 hydrocarbons;
a methane cracking unit fluidly connected to the scrubbing unit and configured to crack the C1-C4 hydrocarbons and separate methane from C2-C4 hydrocarbons;
a steam cracking unit fluidly connected to the separator and methane cracking unit and configured to steam crack the C2-C4 hydrocarbons and the C5+ hydrocarbons; and
an aromatization process unit fluidly connected to the steam cracking unit and configured to separate aromatic hydrocarbons from the C2-C5+ hydrocarbons.
