Propylene oxide reactor gas distribution system
A device for reacting fluids comprising: a reactor; a first inlet for transporting a first fluid into the reactor; a first tube system contained within the reactor and connected to and communicating with the first inlet for receiving the first fluid from the first inlet, the first tube system comprising at least one first tube in the form of a ring, the at least one first tube comprising outlets for releasing the first fluid into the reactor; a second inlet for transporting a second fluid into the reactor; and a second tube system contained within the reactor and connected to and communicating with the second inlet for receiving the second fluid from the second inlet, the second tube system comprising at least one second tube in the form of a ring, the at least one second tube comprising outlets for releasing the second fluid into the reactor; wherein at least one first tube and at least one second tube are concentric, and the outlets for releasing the first fluid from the at least one first tube and the outlets for releasing the second fluid from the at least one second tube are positioned so that, upon release of the first and second fluids, the first and second fluids are directed towards each other.
1 . A device for reacting fluids comprising:
a reactor;
a first inlet for transporting a first fluid into the reactor;
a first tube system contained within the reactor and connected to and communicating with the first inlet for receiving the first fluid from the first inlet, the first tube system comprising at least one first tube in the form of a ring,
the at least one first tube comprising outlets for releasing the first fluid into the reactor;
a second inlet for transporting a second fluid into the reactor; and
a second tube system contained within the reactor and connected to and communicating with the second inlet for receiving the second fluid from the second inlet, the second tube system comprising at least one second tube in the form of a ring,
the at least one second tube comprising outlets for releasing the second fluid into the reactor;
wherein at least one of the first tubes and at least one of the second tubes are concentric, and the outlets for releasing the first fluid from the at least one first tube and the outlets for releasing the second fluid from the at least one second tube are positioned so that, upon release of the first and second fluids, the first and second fluids are directed towards each other.
2 . The device of claim 1 wherein the at least one of the first tubes and the at least one of the second tubes lie substantially in the same horizontal plane.
3 . The device of claim 1 wherein the reactor is a column having a top portion, a bottom portion, and a sidewall portion, and the at least one first tube and the at least one second tube are arranged at a position within the bottom portion of the reactor.
4 . The device of claim 3 wherein
the at least one first tube and the at least one second tube each comprise a top side and a bottom side, the top side of the first and second tubes facing the top portion of the reactor, and the bottom side of the first and second tubes facing the bottom head of the reactor, and
the outlets for releasing the first fluid from the at least one first tube and the outlets for releasing the second fluid from the at least one second tube are each positioned on the bottom side.
5 . The device of claim 4 wherein the first inlet for transporting the first fluid into the reactor is positioned at the sidewall portion of the reactor and the second inlet for transporting the second fluid into the reactor is positioned at the bottom portion of the reactor.
6 . The device of claim 2 wherein the outlets for releasing the first fluid from the at least one first tube and the outlets for releasing the second fluid from the at least one second tube are positioned at angles of from 5 to 85 degrees relative to the horizontal plane of the respective first and second tubes.
7 . The device of claim 1 wherein the outlets for releasing the first fluid from the at least one first tube and the outlets for releasing the second fluid from the at least one second tube further comprise a shroud.
8 . The device of claim 1 wherein the first tube system further comprises a control valve.
9 . The device of claim 1 wherein the second tube system further comprises a control valve.
10 . A process comprising:
feeding a first fluid into a reactor containing a solvent and a catalyst, through a first tube system contained within the reactor, the first fluid comprising oxygen; and
feeding a second fluid into the reactor through a second tube system contained within the reactor, thereby forming propylene oxide, the second fluid comprising propylene and hydrogen,
wherein the first tube system and second tube system are positioned such that, upon release into the reactor, the first and second fluids are directed towards each other.
