Abstract
A system and method for production of olefin products from a hydrocarbon feedstock is disclosed. The system can include a mixed feed steam cracking unit coupled to an ethane steam cracking unit where the mixed feed steam cracking unit produces olefins and ethane. The ethane can be further processed in the ethane steam cracking unit to produce ethylene and C2+ hydrocarbons. The C2+ hydrocarbons can be recycled to the mixed feed steam cracking unit.
Claims14
A system for the production of olefins, the system comprising:
- a mixed feed steam cracking unit capable of producing an olefin product stream and an ethane (C2) product stream;
- an ethane steam cracking unit capable of producing a C2+ stream;
- and
- a first conduit coupled to the mixed feed steam cracking unit and the ethane steam cracking unit, the first conduit capable of receiving the C2 product stream from the mixed feed steam cracking unit and providing the C2 product stream to the ethane steam cracking unit;
- a second conduit coupled to the ethane steam cracking unit and the mixed feed stream cracking unit, the second conduit capable of receiving the C2+ stream from the ethane steam cracking unit and providing the C2+ stream to the mixed feed stream cracking unit.
2 more elements
A process for the production of olefins, the process comprising:
- (a) in a mixed feed steam cracking unit, subjecting a mixed hydrocarbon feed stream to conditions sufficient to produce olefin products and ethane (C2) hydrocarbons;
- (b) separating the C2 hydrocarbons from the olefin products to produce a C2 hydrocarbon stream and an olefin products stream;
- (c) subjecting the C2 hydrocarbon stream to an ethane steam cracking unit under conditions sufficient to produce a C2+ hydrocarbons stream;
- and
- (d) subjecting the C2+ hydrocarbons stream to the mixed feed steam cracking unit.
