Abstract: Provided is a continuous process for converting waste plastic into recycle for polyethylene polymerization. In one embodiment, the process comprises selecting waste plastics containing polyethylene and/or polypropylene and passing the waste plastics through a pyrolysis reactor to thermally crack at least a portion of the polyolefin waste and produce a pyrolyzed effluent. The pyrolyzed effluent is separated into offgas, a naphtha/diesel fraction, a heavy fraction, and char. The naphtha/diesel fraction is passed to a crude unit distillation column in a refinery where a straight run naphtha (C5-C8) fraction or a propane/butane (C3-C4) fraction is recovered. The straight run naphtha fraction (C5-C8) or the propane/butane (C3-C4) fraction is passed to a steam cracker for ethylene production. The heavy fraction from the pyrolysis unit can also be passed to an isomerization dewaxing unit to produce a base oil.

Abstract: Processes for producing liquid fuels from a mainly organic starting material with a reduced content in water and/or with a reduced content in solids are disclosed. The mainly organic starting material can be at least partially liquified and optionally further dewatered. The obtained at least partially liquid fraction can be thereafter used as feeding stream that is submitted to a pyrolysis treatment resulting in a solid gas fraction allowing the recovering of a liquid fuels after a controlled liquid solid separation treatment. There are also provided various other processes for producing liquid fuel from waste hydrocarbon and/or organic material as well as reactors, apparatuses, uses and managing systems thereof.

Abstract: Commercially beneficial carbon-containing fractions can be recovered from hydrothermal liquefaction reactions in various types of processors. Feedstock slurry from waste solids is placed into a pressurized processor where it is maintained at temperature and pressure for a predetermined period. On discharge from the processor the processed discharge is separated into liquid and solid fractions. Gaseous fractions including carbon dioxide can also be removed or off-taken from the processor. New molecular structures are created in this reaction, resulting in fractions including biogas, biofuels, biosolids and biocrude. Silica, phosphates, potash and low concentration nitrogen based fertilizer, along with carbonaceous material can also be recovered.

Abstract: A method for thermally converting plastics and biomass, and especially non-recyclable waste plastic and or biomass, to primarily liquid phase hydrocarbons is a three step process comprised of hydrothermal treatment, steam cracking and coking. Plastic or plastic and biomass feedstocks are reduced in particle size to inch minus or smaller and suspended in a liquid slurry. The slurry is pumped to high pressure and heated to a temperature high enough to initiate de-polymerization. The resulting partially de-polymerized slurry is sent to a multi-phase separation system via a pressure reduction valve and thereafter subjected to steam cracking to further reduce the average molecular weight of the hydrocarbon components. The resulting gas phase hydrocarbon mixture is quenched, and naphtha, middle distillate, and heavy oils are condensed out. The residual heavy oil phase is further reduced in pressure and sent to a coker from which additional liquid hydrocarbon product is recovered.

Abstract: Process and systems for converting waste plastics include feeding a waste plastic to a melt tank, and in the melt tank, heating the waste plastic to form a molten plastic. The molten plastic is withdrawn from the melt tank and fed to a pyrolysis reactor. In the pyrolysis reactor, the molten plastic is heated to a pyrolysis temperature, producing a pyrolysis oil product and a liquid pitch product. The pyrolysis oil is then separated into a pyrolysis gas fraction, a light pyrolysis oil fraction, a medium pyrolysis oil fraction, and a heavy pyrolysis oil fraction.
