Abstract: The invention relates to a process for the preparation of an ethylene-based polymer, the process comprising: a) suspension polymerizing ethylene and an optional comonomer to obtain a suspension (11) comprising the ethylene-based polymer and wax in a suspension medium comprising a diluent, b) separating the ethylene-based polymer (13) from the suspension (11) to obtain a liquid stream (12) comprising the diluent and the wax, c) feeding at least part of the liquid stream (25) to a forced circulation reboiler (Q) for separating the diluent and the wax to obtain an evaporated stream (27) comprising the diluent, wherein the evaporated stream (27) is recycled to step a).

Abstract: Disclosed are methods and systems for desulfurization of CO-rich streams. A method can include contacting a CO-rich gas stream with activated carbon and/or contacting the CO-rich gas stream with a zinc-oxide sorbent material at a temperature of ( ) to 50° C. to remove at least a portion of the sulfur-containing compounds present in the stream.

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: Disclosed are methods and systems for desulfurization of CO-rich streams. A method can include contacting a CO-rich gas stream with activated carbon and/or contacting the CO-rich gas stream with a zinc-oxide sorbent material at a temperature of 0 to 50° C. to remove at least a portion of the sulfur-containing compounds present in the stream.

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.
