Abstract: A system and method for determining a rate of flow of an output from a vessel. The system includes a vessel having an inlet for receiving an output produced by an output generation device, and a measuring device for measuring a first pressure, a first temperature and a second pressure and a second temperature in the vessel. The first pressure and first temperature are measured when the output generation device is in a standby mode and the second pressure and second temperature are measured when the output generation device is in an operational mode. The system includes a programmable logic controller configured to calculate a rate of flow of the output utilizing the first pressure, the first temperature, the second pressure and the second temperature.

Abstract: A system and method is presented for reducing a concentration of ambient air used in a feed stream to form an inerting gas in a pressure swing adsorption system. The method includes introducing ambient air into a pressure swing adsorption system to form an inerting gas, introducing the inerting gas to a large volume of atmosphere, thereby inerting at least a portion of the large volume of atmosphere to form an inerted atmosphere, and removing a portion of the inerted atmosphere and introducing the portion of inerted atmosphere to the pressure swing adsorption system to form the inerting gas, thereby reducing an amount of ambient air utilized to form the inerting gas in the pressure swing adsorption system.

Abstract: A gas separation vessel has a vessel shell and a partition therein. A first bed support is mounted between the partition and the shell, and a second bed support is mounted within the partition to define a second bed space. First and second ports on the vessel shell beneath the bed supports permit gas flow between the bed spaces and the exterior of the vessel shell. A separation medium is placed in the bed spaces. A feed gas is introduced into the vessel to flow through the first bed and then through the second bed to separate at least one component of the feed gas from the other intermixed gases. Output gas is then collected from the vessel. The vessel may have a L:D ratio of not more than 4:1.

Abstract: A method of autonomously sharing a load between at least two output generation devices, the method including: providing at least two output generation devices, wherein the at least two output generation devices operate autonomously with respect to one another and the at least two output generation devices are in fluid communication with output receiving means adapted to receive output generated by the at least two output generation devices; monitoring output generated by the output generation devices; and cycling each of the at least two devices through an activated mode and a standby mode independently of one another in an automated manner to meet an output demand thereby sharing a load demand between the at least two output generation devices.

Abstract: A fire-fighting foam is made by cooling a liquid concentrate, combining the cooled liquid concentrate composition with an expansion gas, and allowing the combined liquid concentrate and expansion gas to expand. A diffuser for dispensing a fire-extinguishing product has a discharge line having an interior, a discharge line intake and a diffuser outlet. There is a casing around a portion of the discharge line, the casing enclosing a space around said portion of the discharge line. The casing has an inlet and an outlet, and the discharge line has an aspirator inside the casing. A fire-fighting foam can be made by flowing a liquid concentrate through the diffuser via the diffuser intake, flowing an expansion gas into the inlet, and dispersing the liquid-gas composition via the diffuser outlet to yield a fire-fighting foam.

Abstract: A fluid adsorption system is provided with a waste saving valve interconnecting companion adsorption beds of the system at the inlets for the adsorption beds. A solenoid control is also provided to control the intermittent actuation of the waste saver valve. The control momentarily interrupts the fluid flow of the feed stream toward the beds and actuates the waste saver valve to provide partial pressurization of the depressurized bed by gas flowing from only the inlet end of the companion bed. The pressure equalization occurs quite rapidly and the control then interconnects the feed stream with the second bed so as to initiate the adsorbing process while simultaneously connecting the first bed to a waste fluid exhaust outlet to provide for discharge of the remaining gases therein and regeneration of the first bed.
