  • Patent number: 10786755
    Abstract: Low-retention pre-columns that allow increased injection volumes of solvents chromatographically stronger than the mobile phase and use of solvents with limited solubility in the mobile phase, such as ethyl acetate and MTBE. The system and method also reduces band broadening due to the extra-column effects acting upstream of the analytical column, including band broadening due to the injection process and due to the connecting tubing and fittings between the injection system and the column. A pre-column may also be used as a guard column, thereby minimizing band broadening due to the guard column.

  • Patent number: 10563555
    Abstract: Systems and methods for capturing carbon dioxide (CO2) in exhaust gases of a vehicle include delivering the exhaust gas to a cooled section of a rotary contactor, the rotary contactor including openings that extend from a first side of the rotary contactor to a second side of the rotary contactor. The CO2 of the exhaust gas is adsorbed with a sorbent of the cooled section of the rotary contactor, where the non-CO2 components of the exhaust gas pass through the openings. The cooled section of the rotary contactor is heated with a hot fluid of the vehicle to release the adsorbed CO2 and convert the cooled section of the rotary contactor to a heated section of the rotary contactor. The heated section of the rotary contactor is cooled to convert the heated section of the rotary contactor back to the cooled section of the rotary contactor.

The crude biogas is treated upstream of the carbon dioxide separation method, and is desulphurized and dried and minor components can be removed. For avoiding impurities in the biogas, at the start of the adsorption phase a purge process is carried out on the adsorber with treated crude biogas, wherein the purge process is controlled with respect to time via a number of valves and a sensor.

  • Patent number: 8647411
    Abstract: A method of removing mercury from a process gas by means of a sorbent and a filter (10) involves applying said sorbent to at least one filtering surface (12) of the filter (10). A first parameter, which is indicative of the amount of mercury that needs to be removed in said filter (10), and a second parameter, which is indicative of the amount of material that has been collected on said filtering surface (12), are measured. A measured value of said first parameter is compared to a mercury set point. When said measured value of said first parameter is higher than said mercury set point, the cleaning of said filtering surface (12) is delayed, compared to the point in time suggested by a measured value of said second parameter.

  • Patent number: 8631770
    Abstract: A waste gas combustion method that includes providing a combustible fuel source, in which the combustible fuel source is composed of at least methane and siloxane gas. A sodium source or magnesium source is mixed with the combustible fuel source. Combustion of the siloxane gas of the combustible fuel source produces a silicon containing product. The sodium source or magnesium source reacts with the silicon containing product to provide a sodium containing glass or sodium containing silicate, or a magnesium containing silicate. By producing the sodium containing glass or sodium containing silicate, or the magnesium containing silicate, or magnesium source for precipitating particulate silica instead of hard coating, the method may reduce or eliminate the formation of silica deposits within the combustion chamber and the exhaust components of the internal combustion engine.

  • Publication number: 20130340611
    Abstract: The invention relates to a method and apparatus for reducing nitrosamines, formed in removal of CO2 from off-gases by means of an aqueous amine solution. A substream of the aqueous amine solution, loaded with nitrosamines, is branched off from a washing fluid circulation and is concentrated by evaporating water and low-boiling constituents. The concentrated amine solution is retained at the boiling point in a unit in which a liquid phase and a vapor phase are in contact to establish a vapor/fluid equilibrium between the phases. The vapor phase is irradiated with UV light, which decomposes nitrosamines entering the vapor phase. Following decomposition of nitrosamines, the concentrated amine solution is recycled to the washing fluid circulation for further use in the scrubber.

  • Patent number: 8580016
    Abstract: A bypass unit for a water vapor transfer assembly includes a main body, a check valve, and an adjustable flow regulator. The main body has a conduit formed therethrough. The check valve is in communication with the conduit. The check valve normally militates against a flow of a bypass stream through the conduit and permits the flow of the bypass stream through the conduit above a threshold flow rate. The flow regulator is in communication with the conduit. The flow regulator permits an adjustment of the flow of the bypass stream to modify the water transfer rate of the water transfer assembly.

  • Patent number: 8529660
    Abstract: A control device for a compressed air preparation device of a vehicle outputs output signals for adjusting feed phases and regeneration phases of the compressed air preparation device. A compressor feeds compressed air via an air dryer having a desiccant into a compressed air reservoir in a feed phase, and compressed air is passed out of the compressed air reservoir through the air dryer for drying the desiccant in a regeneration phase. The control device adjusts the regeneration phases depending on a current or future engine load and/or a current or future consumption of compressed air by the vehicle. In overrun phases, the desiccant can be excessively dried to a low moisture level in order to save fuel in later travel segments. Route-optimized regeneration of the desiccant as a function of engine load and/or utilization phases can also be effected.

  • Publication number: 20130205998
    Abstract: Carbon dioxide is removed from a source gas stream by admission to a vessel containing a quantity of a material preferentially absorbing carbon dioxide. The carbon dioxide content of an escaping gas stream is monitored. When the carbon dioxide content of the escaping gas stream indicates that absorbent is saturated with carbon dioxide, an inlet valve is closed, and a vacuum applied, causing the carbon dioxide to be desorbed for collection.

  • Patent number: 8506675
    Abstract: A composite desiccant material is formed by a porous, absorbent substrate of PVA foam or non-woven fibrous sheet is soaked in a solution of a hygroscopic desiccant such as CaCl2. The desiccant is held in pores or fibrous entraining areas sized ranging from 50 microns to 1000 microns. Thin sheets are arranged in a stack in a multi-chamber system, while in an absorption state, uses this stack in a main chamber to absorb H20 from atmospheric gas flowing through that chamber. In a regeneration state atmospheric flow is stopped and low-grade energy releases the H20 from the desiccant into that chamber. Fans circulate moist air through the main chamber and into an adjacent chamber for H20 transfer through or past a partially permeable barrier into a cooling/condensing area. Both H20 and dry gas may be produced.

  • Patent number: 8475563
    Abstract: In a method of treating a gas stream, an aqueous scrubbing liquor is circulated through an essentially closed loop (20) comprising an electrochemical unit (48) for reducing the acidity of the liquor. A portion of the circulating liquor is diverted away from the closed loop (20) to a gas scrubbing unit (10). The gas stream enters the scrubbing unit (10), wherein an acid, for example HF and solid particulates, for example SiO2 particulates, within the gas stream dissolve in the diverted liquor. The diverted liquor is subsequently returned to the closed loop (20), and is replenished in the scrubbing unit (10) by fresh liquor diverted from the closed loop (20). A device (46) is provided for monitoring the acidity of the liquor at a location within the closed loop (20). The reduction in the acidity of the liquor by the electrochemical cell (48) is controlled depending on the monitored concentration.
