  • Patent number: 9956522
    Abstract: Methods of reducing the water content of a wet gas are presented. In one case, the method includes exposing the gas to an amine-terminated branched polymer solvent to remove a substantial portion of the water from the wet gas, exposing the diluted solvent to carbon dioxide to phase separate the solvent from the water, and regenerating the solvent for reuse by desorbing the carbon dioxide by the application of heat. In another case, the method includes exposing the gas to a cloud-point glycol solvent to remove a substantial portion of the water from the wet gas, heating the diluted solvent to above a cloud point temperature for the solvent so as to create a phase separation of the solvent from the water so as to regenerate the solvent for reuse, and directing the regenerated solvent to a new supply of wet gas for water reduction.

  • Patent number: 9815014
    Abstract: A driving system for a reversing blower adsorption based air separation unit is configured to not only drive the reversing blower cyclically in a forward and in a reverse direction, but also to allow the reversing blower to coast during a portion of its operating cycle. While coasting, a pressure differential across the blower acts alone to switch the reversing blower between a forward and a reverse direction of operation. Less power is thus required. When coasting, the blower can also be configured to output power such as the drive motor functioning as an electric generator or by having a mechanical power input be driven by the blower for power generation and/or energy storage. Such a system beneficially utilizes the energy associated with the pressure differential across the blower for energy harvesting and to further accelerate cycle times for the reversing blower adsorption based air separation unit.

    Abstract: High volumetric-efficiency thermally integrated systems for capturing a target gas from a process gas stream include a monolithic body and a distribution system. The monolithic body includes a first plurality of channels and a second plurality of channels each having sorbent surfaces that reversibly adsorb the target gas. The channels are in thermal communication such that heat from an exothermic adsorption of target gas in one plurality of channels is used by an endothermic desorption of target gas from the other plurality of channels. Methods for separating a target gas from a process gas stream include switching the high volumetric-efficiency thermally integrated systems between a first state and a second state. In the first state, the first plurality of channels undergoes desorption while the second undergoes adsorption. In the second state, the second plurality of channels undergoes desorption while the first plurality undergoes adsorption.

A charge cycle circulates air through the device to remove water vapor from the airstream. A subsequent extraction cycle removes water collected in the liquid desiccant by a condenser communicating with the chamber. An integral heat exchanger adds heat to the chamber during the extraction cycle.

  • Patent number: 8496738
    Abstract: A mixed gas is separated with collection of at least one constituent gas. An inlet leads to a blower or other gas compression element through a valve. This blower feeds a chamber which contains media which selectively adsorbs the constituent gas to be collected, such as nitrogen from air. An exhaust from the chamber leads to an exhaust through a check valve. The blower can be reversed after nitrogen has been adsorbed within the chamber to desorb nitrogen and deliver nitrogen back through the blower. The inlet valve is closed after blower reversing and a separate diversion pathway is opened so that nitrogen is delivered from the blower to a nitrogen collection region. A variant system also includes an oxygen collection region on a side of the chamber opposite the blower for collection of both nitrogen and oxygen separated from air simultaneously, or collection of other constituent gases.

  • Patent number: 8491685
    Abstract: A dust collection arrangement employs a variable frequency drive to supply AC to its fan motor. A current sensor measures the current drawn by the motor, and this is compared with a preset value. The variable frequency drive adjusts the frequency of the AC applied to the motor to maintain the motor current at the preset level. This keeps the flow of air in the system optimal as dust producing tools are added or taken off.

  • Patent number: 8491686
    Abstract: A dust collector arrangement has a dust separator supported on a frame, with a lid for the dust collection barrel is mounted onto the frame below it. The lid is supported at a fixed elevation above the surface of the shop floor to create a space or clearance between the rim of the dust collection barrel and the lid. The barrel is supported on casters, and can be rolled into place under the rim, and can be rolled out for emptying. Over-center latches positioned at intervals around the upper part of the barrel side wall, engage corresponding structure on the lid. These pull the barrel upwards against the lid and with the barrel casters lifted off the floor surface. The latch members release to lower the barrel for emptying.

  • Publication number: 20130160643
    Abstract: A self-cleaning sorbent injection lance includes a lance arm, a lance outlet connected to a sorbent arm, a sorbent inlet connected to the lance arm, an air control valve connected to the lance arm, and a electrical valve control connected to the air control valve. The sorbent inlet provides sorbent material passing through the lance arm. The electrical valve control opens the air control valve when receiving an electrical signal, so that compressed air is supplied to the injection lance for cleaning sorbent material clogged in the lance arm and lance outlet without taking the self-cleaning sorbent injection lance off-line.

  • Publication number: 20130156646
    Abstract: A method for degassing a liquid by means of a piston pump unit having a receiving chamber serving for accommodating the liquid to be degassed and connected with at least one supply line and at least one drain line, and a piston seated in the receiving chamber for performing stroke movements and liquid sealing the receiving chamber on one end. The following steps are included: drawing liquid via the supply line into the receiving chamber by performing a first stroke movement of the piston in the case of blocked drain line and open supply line; producing a negative pressure in the receiving chamber by continuing the first stroke movement of the piston in the case of blocked supply line and blocked drain line; and opening the drain line and removing a gas phase present in the receiving chamber from the receiving chamber via the drain line by performing a second stroke movement of the piston directed counter to the first stroke movement in the case of an opened drain line and blocked supply line.

  • Patent number: 8465568
    Abstract: A method of controlling operation of an electrostatic precipitator (6) is provided wherein a soot-blowing operation is performed in an upstream device. According to the method, a signal is sent to a controller (34) that a soot-blowing operation is about to be initiated in the upstream device (2). The controller (34) is operative for controlling performance of a rapping event with respect to the electrostatic precipitator (6), and causes a rapping decision (52; 152) to be made, based on receipt of the signal. The rapping decision includes establishment of a first point in time (T1) for initiating performance of a rapping event with respect to the electrostatic precipitator (6), such that said first point in time (T1) is correlated to a second point in time (T2). The second point in time (T2) is the time at which the soot-blowing operation of upstream device (2) is initiated.

    Abstract: A hydrogen manufacturing system for performing offgas flow control includes: a vaporizer (1) for heating a material mixture containing a hydrocarbon material; a reforming reactor (2) for generating hydrogen-containing reformed gas by reforming reactions of the material; a PSA separator (5) for repeating a cycle of adsorption and desorption, where in the adsorption PSA separation is performed with an adsorption tower loaded with an adsorbent to adsorb unnecessary components in the reformed gas and extract hydrogen-enriched gas out of the tower, and in the desorption the offgas containing the unnecessary components from the adsorbent and remaining hydrogen is discharged from the tower; and a buffer tank (6) for holding the offgas before supplying to the vaporizer. The offgas flow supply from the tank (6) to the vaporizer is changed continuously over time when the cycle time is changed according to load change on the separator (5).
