Abstract
A device for transferring pressure from one fluid stream to another utilized in conjunction with a storage vessel where fluid is stored at ambient pressure and a desired temperature. An entering fluid stream at another temperature is introduced to the device under pressure and the energy of the fluid stream is utilized to pump a second fluid stream of approximately the same flow and pressure from the vessel. The entering fluid flows into the vessel at approximately ambient pressure at its original temperature where it replaces the removed fluid.
Claims12
For providing a non-pressurized reservoir in a pressurized-fluid line, the combination comprising:
- A. a vessel for containing fluid;
- and
- B. a fluid-driven pump including a control inlet, a control outlet, a pump inlet, and a pump outlet, the pump being operable by flow of liquid into the control inlet, through the pump, and out the control outlet to draw liquid in the pump inlet, through the pump and out the pump outlet, the control outlet and the pump inlet being disposed in communication with the interior of the vessel so that fluid that has flowed from the control inlet through the pump and out the control outlet is discharged into the vessel and that fluid thus contained in the vessel is drawn by the pump from the vessel into the pump inlet, through the pump, and out through the pump outlet, whereby pressure is effectively transmitted from the fluid at the control inlet to the fluid at the pump outlet without imposing the pressure on the fluid in the vessel.
