Processes and systems for making recycle content hydrocarbons, including olefins, from recycled waste material. Recycle waste material may be pyrolyzed to form recycle content pyrolysis oil composition (r-pyoil), at least a portion of which may then be cracked to form a recycle content olefin composition (r-olefin). The r-olefin may then be further separated into product streams in a separation zone downstream of the cracker furnace. The presence of recycle content hydrocarbons may facilitate more efficient operation of one or more distillation columns in the separation zone, including the propylene fractionator.

Method to change the molecular composition of a target medium under a condition of modified physical vacuum structure, includes introducing into an exposure chamber the target medium having a Raman spectrum with a predetermined target spectral resonance; rotating a source hydrocarbon medium in a drum adjacent to the exposure chamber, to produce a vacuum and magnetic influence; propagating the vacuum and magnetic influence to the target medium in the exposure chamber; applying a mechanical vibration to the target medium to vibrate the target medium on a molecular scale, to create colloidal molecular vibrations; transferring energy from the colloidal molecular vibrations to an electron system of atoms in molecules of the target medium until at least a portion of the molecules of the target medium cracks into shorter molecular hydrocarbon products; and withdrawing the shorter hydrocarbon molecular products from the exposure chamber.

The disclosure relates to the purification and treatment of oil produced from the liquefaction of waste polymer like for instance the pyrolysis of waste plastics via the polymerization of dienes prior to further treatments.

Processes and facilities for producing a recycled content organic chemical compound directly or indirectly from waste plastic. Processing schemes are described herein for converting waste plastic (or hydrocarbon having recycled content derived from waste plastic) into useful intermediate chemicals and final products. In some aspects, recycled content aromatics (r-aromatics) from a hydrocarbon resin production facility can be processed to provide recycled content paraxylene (r-paraxylene), which can then be used to provide recycled content terephthalic acid (r-TPA) and/or recycled content polyethylene terephthalate (r-PET).

Provided are a method for manufacturing a blended hydrocarbon composition including operation S1) applying voltage to a first blended solution in which waste plastic pyrolysis oil, washing water, and a demulsifier are blended to dehydrate the first blended solution; operation S2) hydrotreating a second blended solution in which the first blended solution dehydrated in operation S1) and a sulfur source are blended to produce refined pyrolysis oil from which impurities have been removed; and operation S3) blending the refined pyrolysis oil from which impurities have been removed in operation S2) with a petroleum-based hydrocarbon to manufacture a blended hydrocarbon composition, and a manufacturing system of the blended hydrocarbon composition.

Provided is a system for bio-oil utilization that can effectively exploit a bio-oil with ease without consideration of its properties and supply-demand balance while utilizing an existing oil refinery facility. The system for bio-oil utilization includes: an atmospheric distillation unit and a bio-oil-supplying mechanism; and at least one kind of unit selected from a gas-recovering unit, a hydrorefining unit, a naphtha-fractionating unit, a catalytic cracking unit, and a vacuum distillation unit. The bio-oil-supplying mechanism is configured to supply a bio-oil, which is derived from a biomass and is subjected to hydrodeoxygenation treatment, to the atmospheric distillation unit together with a stock oil containing crude oil.
