Abstract

A system including a fluid processing system including an absorber configured to remove a component from an untreated first fluid using a lean second fluid, output a treated first fluid, and output a rich second fluid, a stripper configured to strip the component from the rich second fluid, output the lean second fluid, and output the component, a first pump configured to pump the lean second fluid into the absorber, and a hydraulic turbocharger configured to pump the lean second fluid by transferring pressure from the rich second fluid to the lean second fluid.

First claim

What is claimed is:

1. A system, comprising:
a fluid processing system, comprising:
an absorber configured to remove a component from an untreated first fluid using a lean second fluid, output a treated first fluid, and output a rich second fluid;
a stripper configured to strip the component from the rich second fluid, output the lean second fluid, and output the component;
a first pump configured to pump the lean second fluid into the absorber; and
a hydraulic turbocharger configured to pump the lean second fluid by transferring pressure from the rich second fluid to the lean second fluid, wherein the hydraulic turbocharger comprises a turbine section and a pump section.

2. The system of claim 1 , comprising a first valve and a second valve configured to reduce hydraulic instabilities in the fluid processing system, wherein the first valve controls a first flow rate of the lean second fluid through the hydraulic turbocharger and a second valve controls a second flow rate of the lean second fluid through the first pump.

3. The system of claim 2 , comprising a second pump hydraulically parallel with the first pump.

4. The system of claim 3 , comprising a third valve configured to control a third flow rate of the lean second fluid through the second pump.

5. The system of claim 4 , comprising a controller configured to control the first, second, and third valves.

6. The system of claim 5 , comprising a first sensor, a second sensor, and a third sensor coupled to the controller, wherein the first sensor is configured to detect the first flow rate, the second sensor is configured to detect the second flow rate, and the third sensor is configured to detect the third flow rate.

7. The system of claim 1 , wherein the first pump and hydraulic turbocharger couple to a tray in the absorber with hydraulically separate lines.

8. The system of claim 1 , wherein the first pump and the hydraulic turbocharger couple to separate trays in the absorber with hydraulically separate lines.

9. The system of claim 1 , comprising a second pump fluidly coupled to and parallel with the first pump.

10. The system of claim 9 , comprising a first valve and a second valve configured to reduce hydraulic instabilities in the fluid processing system, wherein the first valve controls a first flow rate of the lean second fluid through the hydraulic turbocharger and a second valve controls a second combined flow rate of the lean second fluid through the first and second pumps.
