Hybrid pressure and thermal exchanger

1. An exchanger comprising:

a seal;

a first channel with an inlet and an outlet;

a second channel alongside the first channel and isolated from the first channel by the seal, the second channel including an inlet and an outlet; and

a transfer turbine comprising:

a first portion with one or more blades located within the first channel;

a second portion with one or more blades located within the second channel; and

a shaft connecting the first portion and the second portion such that rotation of the first portion is synchronized with rotation of the second portion, the shaft extending through the seal.

2. The exchanger of claim 1 , further comprising:

an electrical generator stator adjacent the shaft of the transfer turbine;

wherein the shaft of the transfer turbine includes a rotor, which, when rotated by stream flow in the first channel, induces electrical current.

3. The exchanger of claim 1 , wherein force exerted on the blades of the first portion of the transfer turbine by a high-pressure stream causes rotation of the blades of the second portion of the transfer turbine, which transfers pressure from the high-pressure stream to a low-pressure stream in the second channel.

4. The exchanger of claim 3 , wherein the high-pressure stream has a pressure that is greater than a pressure of the low-pressure stream.

5. The exchanger of claim 1 , further comprising:

a third channel adjacent the second channel and including an inlet, and an outlet, with a second seal between the second channel and the third channel isolating the second channel and the third channel.

6. The exchanger of claim 5 , wherein the shaft extends through the second channel and the second seal into the third channel, the shaft further including a third portion including blades and within the third channel such that rotation of the first portion is synchronized with rotation of the second portion and the third portion.

7. The exchanger of claim 6 , wherein force exerted on the blades of the first portion of the transfer turbine by a high-pressure stream entering the first channel inlet and exiting the first channel outlet causes rotation of the blades of the second portion of the transfer turbine, which transfers pressure from the high-pressure stream to a first low-pressure stream entering the second channel inlet and exiting the second channel outlet, and also transfers pressure from the high-pressure stream to a second low-pressure stream entering the third channel inlet and exiting the third channel outlet.

8. The exchanger of claim 1 , wherein the first channel comprises a first pipe and the second channel comprises a second pipe.

9. An energy recycling system comprising:

a pump configured to increase pressure of an input stream to generate a high-pressure stream for use within a process, the process generating a waste stream having a pressure; and

an exchanger configured to receive the waste stream and receive at least a portion of the input stream, the exchanger configured to convert some of the waste stream pressure to the input stream to generate the high-pressure stream, the exchanger comprising:

a seal

a first channel with an inlet configured to receive the waste stream and an outlet for the waste stream to exit the first channel;

a second channel alongside the first channel and isolated from the first channel by the seal, the second channel including an inlet configured to receive the input stream and an outlet for the high-pressure stream to exit the second channel; and

a transfer turbine comprising:

a first portion with one or more blades located within the first channel;

a second portion with one or more blades located within the second channel; and

a shaft connecting the first portion and the second portion such that rotation of the first portion is synchronized with rotation of the second portion, the shaft extending through the seal.

10. The system of claim 9 , the exchanger further comprising:

an electrical generator stator adjacent the shaft of the transfer turbine;

wherein the shaft of the transfer turbine includes a rotor, which, when rotated by the waste stream in the first channel, induces electrical current in the electrical generator stator.

11. The system of claim 9 , wherein force exerted on the blades of the first portion of the transfer turbine by the waste stream causes rotation of the blades of the second portion of the transfer turbine, which transfers pressure from the waste stream to the input stream in the second channel to create the high-pressure stream.

12. The system of claim 9 , the exchanger further comprising:

a third channel adjacent the second channel and including an inlet, and an outlet, with a second seal between the second channel and the third channel isolating the second channel and the third channel.

13. The system of claim 12 , wherein the shaft extends through the second channel and the second seal into the third channel, the shaft further including a third portion including blades and within the third channel such that rotation of the first portion is synchronized with rotation of the second portion and the third portion.

14. The system of claim 13 , wherein force exerted on the blades of the first portion of the transfer turbine by the waste stream entering the first channel inlet and exiting the first channel outlet causes rotation of the blades of the second portion of the transfer turbine, which transfers pressure from the waste stream to the input stream entering the second channel inlet and generating the high-pressure stream exiting the second channel outlet, and also transfers pressure from the waste stream to a second input stream entering the third channel inlet and generating a second high-pressure stream exiting the third channel outlet.

15. The system of claim 9 , wherein the first channel comprises a first pipe and the second channel comprises a second pipe.

16. The system of claim 9 , wherein the high-pressure stream has a pressure that is greater than a pressure of a low-pressure stream.

17. The system of claim 9 , wherein the exchanger receives at least a portion of the input stream in parallel with the pump.

18. The system of claim 9 , wherein the exchanger receives at least a portion of the input stream in series with the pump.
