Abstract
Processes and facilities for providing recycled content hydrocarbon products (r-products) from recycled content pyrolysis oil (r-pyoil) and recycled content pyrolysis gas (r-pygas). Processing schemes provided herein maximize use of recycled content pyrolysis products to provide a variety of recycled content end products.
Claims
exact text as granted — not AI-modified1 . A chemical recycling process, the process comprising:
(a) pyrolyzing waste plastic in a pyrolysis facility to thereby provide a recycled content pyrolysis effluent (r-pyrolysis effluent); (b) separating at least a portion of said r-pyrolysis effluent to provide a recycled content pyrolysis gas (r-pygas) and recycled content pyrolysis oil (r-pyoil); (c) introducing at least a portion of said r-pygas into a cracker facility; and (d) introducing at least a portion of said r-pyoil into a downstream location, wherein the downstream location is not within the cracker facility.
2 . The process of claim 1 , wherein the pyrolysis facility and the cracker facility are co-located.
3 . The process of claim 1 , wherein the r-pygas is introduced into the cracker facility at a location downstream of a cracker furnace.
4 . The process of claim 3 , wherein the r-pygas is introduced into at least one of a quench section, a compression section, and a separation section of the cracker facility.
5 . The process of claim 1 , wherein at least a portion of the r-pygas is introduced into the cracker facility upstream of a cracker furnace and further comprising, cracking at least a portion of the r-pygas to form a recycled content furnace effluent (r-furnace effluent).
6 . The process of claim 1 , further comprising, dividing the r-pyoil into two or more portions and introducing a first portion of the r-pyoil into the downstream location.
7 . The process of claim 1 , wherein the r-pyoil comprises at least 50 weight percent of C4 to C30 hydrocarbon compounds.
8 . The process of claim 1 , wherein the r-pyoil comprises heteroatom-containing compounds in an amount of not more than 20 weight percent.
9 . The process of claim 1 , wherein the r-pygas comprises C2 hydrocarbon components in an amount of 5 to 60 weight percent, C3 hydrocarbon components in an amount of 5 to 60 weight percent, C4 hydrocarbon components in an amount of 1 to 60 weight percent, and C5 hydrocarbon components in an amount of 1 to 25 weight percent.
10 . The process of claim 1 , wherein the downstream location is a carbon reformer.
11 . The process of claim 1 , wherein the downstream location is an oil refinery and further comprising processing at least a portion of the r-pyoil to thereby produce a recycled content fuel (r-fuel).
12 . The process of claim 1 , wherein the downstream location is a burner of a furnace.
13 . The process of claim 1 , wherein the downstream location is another cracker facility.
14 . The process of claim 1 , wherein the downstream location is a fine chemicals production facility.
15 . The process of claim 1 , further comprising cracking a hydrocarbon feedstock in a cracker furnace of the cracker facility to produce a furnace effluent stream, and wherein the furnace effluent stream comprises a recycled content furnace effluent stream (r-furnace effluent).
16 . The process according to claim 15 , wherein the pyrolysis facility and the cracker facility are both commercial scale facilities.
17 . A chemical recycling process, the process comprising:
(a) pyrolyzing waste plastic to thereby provide a recycled content pyrolysis effluent (r-pyrolysis effluent); (b) separating at least a portion of said r-pyrolysis effluent to provide a recycled content pyrolysis gas (r-pygas) and recycled content pyrolysis oil (r-pyoil); (c) introducing at least a portion of said r-pygas into a cracker facility; and (d) introducing at least a portion of said r-pyoil into one or more of the following locations (i) through (x)—
(i) a storage apparatus;
(ii) a transportation apparatus;
(iii) a fluidized catalytic cracker;
(iv) a carbon reformer;
(v) a distillation column or zone;
(vi) a fine chemical facility;
(vii) a burner;
(viii) an MTO facility;
(ix) a different cracker; and
(x) an oil refinery.
18 . The process of claim 17 , wherein the r-pyoil comprises heteroatom-containing compounds in an amount of not more than 20 weight percent, and wherein the r-pygas comprises C2 hydrocarbon components in an amount of 5 to 60 weight percent, C3 hydrocarbon components in an amount of 5 to 60 weight percent, C4 hydrocarbon components in an amount of 1 to 60 weight percent, and C5 hydrocarbon components in an amount of 1 to 25 percent.
19 . The process of claim 17 , wherein the introducing of step (c) includes introducing at least a portion of said r-pyoil into two or more of the locations (i) through (x).
20 . The process of claim 19 , wherein the pyrolysis facility and the cracker facility are co-located and both the pyrolysis facility and the cracker facility are commercial scale.Join the waitlist — get patent alerts
