Abstract: A process for increasing olefin production from refinery that processes hydrocarbon streams that are rich in aromatic compounds and includes steam cracking and hydrotreating an aromatically rich feedstock to produce a hydrotreated pyrolysis gasoline stream and light pyrolysis oil byproduct, saturating at least one additional naphtha/hydrocarbon stream together with the hydrotreated pyrolysis gasoline stream or together with the light pyrolysis oil byproducts to form a first naphthene stream, and steam cracking the first naphthene stream to produce olefins.

Abstract: An integrated process for forming a combined feedstock stream comprising catalytically cracking a first hydrocarbon feedstock to form a full range cracked full naphtha stream and a first light olefins stream, steam cracking a second hydrocarbon feedstock to form a pyrolysis gasoline stream and a second light olefins stream mixing at least a portion of each of the full range cracked naphtha stream and the pyrolysis gasoline stream to form a combined stream, hydro-processing the combined stream to form a hydro-processed combined stream splitting the hydro-processed combined stream into a C5/C6 stream, and a first aromatic rich stream, splitting the first aromatic rich stream into a second aromatic rich stream and a heavy oil stream.
