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.

Abstract: An integrated process for increasing olefin production is described through which heavy cracker residues of fluid catalytic cracking unit and steam cracking unit are completely mixed, and mixed stream is properly recycled and further combined with atmospheric tower bottoms. Combined stream is deasphalted and hydrotreated to produce a proper feedstock for steam cracking unit for manufacturing light olefin compounds. The integrated process produces higher amount of light olefins than a substantially similar process without processing the heavy cracker residues.
