Abstract
A system for providing an adjustable blend of fluids to an application process is disclosed. The system uses a source of a first fluid flowing through at least one tube that is permeable to a second fluid and that is disposed in a source of the second fluid to provide the adjustable blend. The temperature of the second fluid is not regulated, and at least one calibration curve is used to predict the volumetric mixture ratio of the second fluid with the first fluid from the permeable tube. The system typically includes a differential pressure valve and a backpressure control valve to set the flow rate through the system.
Claims9
A system for providing a percentage mixture of a first fluid with a second fluid comprising:
- a source of the second fluid at an unregulated temperature;
- a first tube permeable to the second fluid at a first permeation rate, the first tube having a first tube first end, and a first tube second end, and a first tube middle portion that is disposed in the source of the second fluid;
- a differential pressure regulator to set a fluid pressure drop from the first tube first end to the first tube second end;
- a source of the first fluid to flow the first fluid through the differential pressure regulator into the first tube;
- a thermometer to provide a measurement of the unregulated temperature of the source of the second fluid;
- and
- a first calibration curve to correlate (a) a first volumetric concentration of the first fluid flowing through the first tube and mixing with the second fluid permeating the first tube versus (b) the unregulated temperature of the source of the second fluid.
