Abstract

A combined heat exchanger and reactor for use with an ionic liquid catalyst reaction. The reactor includes an outer shell configured to receive a cooling fluid which may remove heat from reactions occurring within hollow members disposed inside of the outer shell. The hollow members preferably include one or more static mixers for mixing fluids and dispersing ionic liquid into droplets. A separation zone may be disposed beneath the hollow members which will separate the effluent and provide a hydrocarbon stream and an ionic liquid stream. Multiple combined heat exchanger and reactor may be arranged in series.

First claim

The invention claimed is:

1. A reactor for an ionic liquid catalyzed reaction, the reactor comprising:
an outer shell, the outer shell including an inlet for a cooling fluid and an outlet for the cooling fluid;
a hollow member disposed in the outer shell and having a first open end, a second open end opposite the first open end, and at least one static mixer disposed in the hollow member;
a separation zone in fluid communication with the hollow member and configured to separate an effluent into an ionic liquid stream and a hydrocarbon stream; and
wherein the outer shell has a horizontal cross sectional size, and wherein the separation zone comprises a vessel having a horizontal cross sectional size larger than the horizontal cross sectional size of the outer shell.

2. The reactor of claim 1 wherein the reactor further comprises a plurality of hollow members disposed in the outer shell, each hollow member comprising a first opening at a first end and a second opening at a second end opposite the first end, and at least one static mixer disposed in each hollow member.

3. The reactor of claim 2 , wherein the reactor further comprises a manifold in fluid communication with the first ends of the hollow members.

4. The reactor of claim 3 , wherein each hollow member includes at least one static mixer disposed at the first end of the hollow member and proximate the manifold.

5. The reactor of claim 4 further comprising at least one static mixer disposed at the second ends of the hollow members.

6. The reactor of claim 1 further comprising:
a second outer shell disposed between the outer shell and the separation zone, the second outer shell comprising:
an inlet for cooling fluid;
an outlet for the cooling fluid;
at least one hollow member disposed within the second outer shell, the at least one hollow member disposed within the second outer shell having a first open end, a second open end opposite the first end, and a static mixer disposed within the at least one hollow member disposed within the second outer shell.

7. The reactor of claim 6 further comprising:
a plurality of hollow members disposed within both of the outer shell and the second outer shell;
a manifold in fluid communication with the first open ends of the hollow members in the first outer shell; and
a manifold in fluid communication with the second open ends of the hollow members in the first outer shell and the first open ends of the hollow members in the second outer shell.

8. The reactor of claim 1 , wherein the separation zone includes a vertical baffle extending downward from a top of the vessel in the separation zone.

9. The reactor of claim 1 , wherein the hollow member comprises an outer hollow member, and wherein the reactor further comprises an inner hollow member disposed in the outer hollow member.

10. The reactor of claim 9 , wherein the inner hollow member includes an open end and a closed end, and a plurality of discharge openings disposed between the open end and the closed end.

11. The reactor of claim 9 , wherein the at least one static mixer is disposed in an annulus between the outer hollow member and the inner hollow member.

12. The reactor of claim 9 further comprising a plurality of outer hollow members and a plurality of inner hollow members, each outer hollow member surrounding at least one inner hollow member.

13. The reactor of claim 12 further comprising a manifold configured to receive an ionic liquid stream and distribute ionic liquid to the plurality of outer hollow members.

14. The reactor of claim 1 further comprising:
a line configured to pass at least a portion of a reactor effluent from the reactor to a second reactor comprising:
an outer shell having an inlet for cooling fluid;
an outlet for cooling fluid; and
at least one hollow member disposed inside of the outer shell of the second reactor.

15. A reactor for an ionic liquid catalyzed alkylation reaction, the reactor comprising:
an outer shell comprising an inlet for a cooling fluid and an outlet for the cooling fluid;
a plurality of outer hollow members disposed in the outer shell;
an inner hollow member disposed in each of the outer hollow members, and each inner hollow member including an open end, a closed end, and plurality of discharge openings between the open end and the closed end;
at least one static mixer disposed in the outer hollow member; and
a separation zone in communication with the plurality of hollow members and configured to separate an effluent into an ionic liquid stream and a hydrocarbon effluent stream;
a first manifold configured to receive and distribute an ionic liquid catalyst stream;
a second manifold configured to receive and distribute a first hydrocarbon stream; and
a third manifold configured to receive and distribute a second hydrocarbon stream.
