  • Patent number: 10087084
    Abstract: Disclosed are a method, a device and a system of automatic flow control based on sensed effectiveness indicators to produce effectively treated water with a portable water treatment unit. In one or more embodiments, a chemical treatment unit delivers a treatment chemical to water as the water flows at a flow rate induced by a pump capable of operating at multiple speeds. A sensor downstream of the chemical treatment unit measures an effectiveness indicator and a processor and/or a feedback circuit determines an effectiveness of the chemical treatment. A controller changes power to the pump in response to the determination, adjusting the flow rate to ensure efficient usage of a power source and/or to ensure effective production of potable water. One or more filters may be included, each having a bypass valve, and the pump may automatically adjust to changing filter configurations and/or source water composition.

    Abstract: A method for operating a firing plant with at least one combustion chamber and at least one burner, especially a gas turbine, includes an operating characteristic for operating the combustion chamber close to the lean extinction limit defined as a burner group staging ratio (BGVRich). Pressure pulsations (PulsActual) measured in the combustion chamber are processed by a filter device (2) and converted into corresponding signals (PulsActual,Filter(t)). An exceeding/falling short of at least one pulsation limiting value (PulsLimit) is monitored by a monitoring device (3) and adapts a pulsation reference value (PulsRef) in dependence upon the monitoring. The processed pressure pulsations (PulsActual,Filter(t)) are then compared with the adapted pulsation reference value (PulsRef,adapt), and, from this, a correction value ?BGV is determined, by which the burner group staging ratio (BGVRich) is corrected, and as a result operation of the firing plant close to the lean extinction limit is realized.

    Abstract: A method for controlling a selective catalytic reduction system (SCR) exploiting a set of predetermined trigger events and a set point for the NOx concentration, and an arrangement for SCR. At the occurrence of a trigger event, NOx concentration measurement downstream from the catalyst elements is started and the difference between the measured concentration and the set point is determined. If the difference is negative, the dosing of the reducing agent is decreased. If the difference is positive, the dosing of the reducing agent is increased and after system stabilization a new measurement is started. If the measured value is below the previous measured value, the same dosing is maintained. If the measured value is above the previous measured value, the dosing is decreased with an amount greater than the increase after the previous measurement.

  • Patent number: 8303532
    Abstract: A peritoneal function testing apparatus tests the peritoneal function of a dialysis patient easily and with high accuracy. Standards of four kinetic parameters (CCr, Kt/V, MTACu, and MTACc) available in a definite dialysis guideline are computed in accordance with a relational expression, and a curve showing the relation between MTACu/c and the drained fluid volume is indicated in a graph together with the PET data of the patient which has been prepared separately. Thus, the peritoneal function can be evaluated based on the relative position of the patient's data and the curve showing the standard values in the graph.

  • Patent number: 8306665
    Abstract: The present invention provides a control system for the conversion of carbonaceous feedstock into a gas. In particular, the control system is designed to be configurable for use in controlling one or more processes implemented in, and/or by, a gasification system for the conversion of such feedstock into a gas, which may be used for one or more downstream applications. Gasification processes controllable by different embodiments of the disclosed control system may include in various combinations, a converter, a residue conditioner, a recuperator and/or heat exchanger system, one or more gas conditioners, a gas homogenization system and one or more downstream applications. The control system operatively controls various local, regional and/or global processes related to the overall gasification process, and thereby adjusts various control parameters thereof adapted to affect these processes for a selected result.

  • Patent number: 8280554
    Abstract: A novel fail-safe temperature monitoring system that can distinguish excessive chemical adsorbent temperature from temperature sensing component failure is provided. This system prevents the gas purifier from shutting down as a result of temperature sensing component failure, and thereby prevents a false shutdown of a high-purity gas production plant.

  • Patent number: 8158436
    Abstract: The invention provides methods and apparatus for characterizing complex polymeric mixture of interest. Candidate solutions are eliminated from a solution space using one or more experimental measurements of a polymeric mixture of interest. The elimination step can be repeated one or more times using different experimental measurements produced by various chemical and physical protocols, so that the remaining candidate solutions converge to describe the actual polymeric mixture under investigation. Once the composition of the complex polymeric mixture has been characterized, the information thus generated can be used to facilitate, for example, the manufacture of a bio-equivalent of the complex polymeric mixture.

    Abstract: Methods and systems for creating dynamic performance measures (DPMs) for an IBA manufacturing process. Included is a method for monitoring an Isobutyl Alcohol (IBA) recovery system that includes computing at least one of an amount of IBA recovered from the IBA recovery system and an amount of waste material produced from the IBA recovery system, and displaying at least one of the recovered IBA and the waste material produced based on time. The method also includes computing a cost saved based on a cost of virgin IBA and the amount of IBA recovered. Computing an amount of waste material includes measuring waste material flow, and computing a cost of waste material management based on the measured waste material flow and a cost per unit volume to dispose of waste material. The IBA recovery system can include an evaporation IBA recovery system and/or a distillation IBA recovery system.

  • Patent number: 8123715
    Abstract: The present invention is a peritoneal dialysis and hemodialysis hybrid-remedy planning method using an index that is shared by both peritoneal dialysis and hemodialysis and indicates an effect of dialysis. To be specific, the index is M/C(0)/VB, which is obtained by dividing a ratio M/C(0)—where M is a removal amount of a solute for a fixed time period, and C(0) is a concentration of the solute in blood before the dialysis—by a patient's body fluid volume, VB. The present invention is capable of representing the dialysis effect of PD and HD as an integrated sum, and achieving concise and explicit PD and HD hybrid-remedy planning.
