Abstract
Systems and processes for the production of circular products, including circular olefins and circular products derived from the circular olefins, by feeding particular hydrocarbons derived from one or more feed source to steam cracking and to fluid catalytic cracking and by sending the product of steam cracking and the product of fluid catalytic cracking to an integrated separation system. The circular olefins can be used in any downstream process to produce any circular product, such as a circular product produced through polymerization, oligomerization, or hydrogenation of the circular olefins.
Claims20
A process comprising:
- cracking C2 hydrocarbons and C3 hydrocarbons in a steam cracking unit to form a cracked gas;
- cracking C4+ hydrocarbons in a fluid catalytic cracking unit to form a fluid catalytic cracking (FCC) product, wherein the C4+ hydrocarbons comprise butanes, butenes, naphtha, a pyrolysis oil, a used lubricating oil, a bio-based feedstock, a renewable feedstock, a non-renewable feedstock, a circular feedstock, or a combination thereof;
- introducing the cracked gas and the FCC product to a separation system;
- and
- recovering a plurality of hydrocarbon products from the separation system, wherein the plurality of hydrocarbon products comprises one or more circular olefin.
A circular olefin system comprising:
- a steam cracking unit that cracks C2 hydrocarbons and C3 hydrocarbons into a cracked gas;
- a fluid catalytic cracking unit that cracks C4+ hydrocarbons into a fluid catalytic cracking (FCC) product, wherein the C4+ hydrocarbons comprise butanes, butenes, naphtha, a pyrolysis oil, a used lubricating oil, a bio-based feedstock, a renewable feedstock, a non-renewable feedstock, a circular feedstock, or a combination thereof;
- and
- a separation system coupled to the steam cracking unit and to the fluid catalytic cracking unit, wherein the separation system receives the cracked gas and the FCC product, wherein the separation system produces a plurality of hydrocarbon products comprising one or more circular olefin.
