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 (38)

1 . 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.
