  • Patent number: 10295518
    Abstract: Systems and method for detecting a concentration of a gas in a gas stream are disclosed. A method includes receiving a gas stream including a carrier gas and a processing gas. Bridge voltages of a mass flow sensor are used to produce a processing-gas concentration signal and a gas-stream mass flow rate signal. The gas stream is controlled so a mass flow rate of the processing gas equals a processing-gas-setpoint signal. In some variations, the processing-gas-concentration signal is produced using an upstream temperature of the gas stream and a bridge-derived temperature. In other variations, the processing-gas-concentration signal is produced using a top voltage of the mass flow sensor and the gas-stream mass flow rate signal.

  • Patent number: 10195329
    Abstract: A method of providing a concentrate of a dissolved substance for producing a dialysis solution includes providing a container containing a solid to be dissolved, supplying water into the container for dissolving the solid, draining the concentrate of the dissolved substance from the container and topping up with water, measuring the concentration of the dissolved substance or of a parameter correlated with the concentration, and temporary or permanent suppression of the topping up of water into the container. The suppression is effected when the measured concentration value of the dissolved substance falls below a first limit value or the value of the parameter falls below or exceeds a first limit value or when the change in the concentration value of the dissolved substance or of the value of the parameter exceeds a first limit value.

  • Patent number: 10144653
    Abstract: A fluid metering system for accurately and consistently mixing two or more fluids together. The fluid metering system generally includes a closed loop feedback system that monitors the flow rate of the water and the volume of liquid chemical added to the water over a period of time. Based on the measured amount of chemical added to the water over a period of time, the system calculates whether or not an adjustment is required for the next addition of chemical to the water. The present invention utilizes a measuring tube that is filled with a chemical wherein a pressure sensor measures the pressure of the chemical in the measuring tube when filled and after being emptied to calculate the total volume of chemical added to the water.

  • Patent number: 8950419
    Abstract: A method and system for supplying additional hydrogen from a reservoir of stored hydrogen in a salt cavern to a hydrogen pipeline to assist in meeting customer demand for hydrogen is provided. Contaminants introduced while the stored hydrogen stream is in the salt cavern may cause the crude hydrogen stream to not have the required product purity specification. The stored hydrogen is removed from the salt cavern as a crude hydrogen stream and thereafter diluted with higher purity hydrogen formed from the pipeline to form a hydrogen product stream at or below the product purity specification. The hydrogen product can be formed without removal of any of the contaminants in the crude stream, thereby creating a more cost effective and simplified supply process compared to conventional processes employing a salt cavern for hydrogen supply.

The system includes an on board separation unit (OBS unit) for receiving and separating intermediate autoignition temperature (IAT) fuel into low and high autoignition temperature fuels, LAT and HAT, respectively. The production rate of the LAT and HAT fuels by the OBS unit is controlled to substantially match the consumption requirements of the engine at any given time for the LAT and HAT fuels.

  • Patent number: 7537018
    Abstract: An embodiment of the present invention is a method for creating and maintaining a partial vapor pressure in a sample chamber of a sorption analyzer. A first dry gas flow is purged from a first mass flow controller through a saturator to produce a near-saturated gas flow. The near-saturated gas flow is mixed with a second dry gas flow from a second mass flow controller to produce a mixed gas flow with a predetermined partial vapor pressure. The mixed gas flow is directed into the sample chamber. If the lowest possible vapor pressure is required in the sample chamber, the first dry gas flow is directed around the saturator to the sample chamber and vapor migrating from the saturator is vented to the atmosphere.

  • Patent number: 7448102
    Abstract: A method for supplying liquid mixtures on a mix-on-demand basis for consumptive use, and for maintaining the composition of such mixture on a highly accurate and stable basis. For wet-on-wet processing of fabrics, the processing solution is supplied at start-up on a mix-on-demand basis to precise specifications and is maintained at such precise specifications throughout fabric processing, which involves continuous additions of water by the incoming fabric and removal of solution by the exiting fabric. Recirculation of the solution at a high rate, together with rapid and repetitive measurements of the composition of the recirculating solution enables the solution to be precisely monitored and maintained. Periodic small additions of chemical are injected as necessary to maintain highly stable, accurately controlled process conditions. Extraordinary economies, both direct and indirect, can be realized with the new system.

  • Patent number: 7438079
    Abstract: Method for supplying a high purity gas product comprising providing a first gas stream including a major component and at least one impurity component, determining the concentration of the at least one impurity component, and comparing the concentration so determined with a reference concentration for that component. When the value of the concentration so determined is less than or equal to the reference concentration, the first gas stream is utilized to provide the high purity gas product. When the value of the concentration so determined is greater than the reference concentration, a second gas stream comprising the major component is provided and the first and second gas streams are mixed to yield a mixed gas stream having a concentration of the at least one impurity component that is less than the reference concentration. The mixed gas stream is utilized to provide the high purity gas product.

  • Patent number: 7360550
    Abstract: A system for recycling spent sulfuric acid, wherein spent sulfuric acid is effectively utilized at a place other than a discharge source regardless of geographical conditions, and a method for recycling waste sulfuric acid. In the system, when spent sulfuric acid that is discharged or collected at a discharge source is transported by a carrier unit and used at a user office a concentration of the spent sulfuric acid is measured and/or adjusted at least at one of the discharge source, the carrier unit, and the user office. The spent sulfuric acid waste liquid that is discharged or collected at the discharge source is reutilized by being mixed with at least one of a hydrogen peroxide solution and water.
