  • Patent number: 11047321
    Abstract: Methods and systems are provided for assessing a working capacity of a fuel vapor storage canister positioned in an evaporative emissions system configured to capture and store fuel vapors from a fuel system. In one example, a method comprises, in response to fuel vapor being adsorbed by, or desorbed from, the fuel vapor canister, sealing the evaporative emissions system and indicating degradation of the fuel vapor canister in response to a monitored pressure change in the evaporative emissions system less than a threshold pressure change. In this way, working capacity of the fuel vapor storage canister is inferred, which may allow for a reduction in undesired evaporative emissions to atmosphere.

  • Patent number: 11007473
    Abstract: Methods and systems for removing water vapor from a feed gas prior to further processing the feed gas according to a downstream PSA process are described. The feed gas can include CO2 and/or CO and/or H2 and the PSA process can be used to separate components of the feed gas from one another, for instance, for CO2 capture. Light product off of the PSA process is utilized to regenerate desiccant of a dryer used in the water vapor removal process that is carried out prior to the feed gas entering the PSA process. The water vapor removal process can be heated by providing thermal energy directly to the dryer and/or to a regenerating stream that regenerates the desiccant of the dryer. The thermal energy can be low cost energy—for instance, waste heat off of a system that provides the feed gas.

  • Patent number: 10981784
    Abstract: According to the present invention, organic material is converted to biogas through anaerobic digestion and the biogas is purified to yield a combustible fluid feedstock comprising methane. A fuel production facility utilizes or arranges to utilize combustible fluid feedstock to generate renewable hydrogen that is used to hydrogenate crude oil derived hydrocarbons in a process to make transportation or heating fuel. The renewable hydrogen is combined with crude oil derived hydrocarbons that have been desulfurized under conditions to hydrogenate the liquid hydrocarbon with the renewable hydrogen or alternatively, the renewable hydrogen can be added to a reactor operated so as to simultaneously desulfurize and hydrogenate the hydrocarbons. The present invention enables a party to receive a renewable fuel credit for the transportation or heating fuel.

  • Publication number: 20130104735
    Abstract: A method for removing volatile organic substances from the contained air of closed habitats includes a) conducting contained air through an adsorber bed formed by a hydrophobic zeolite bed, b) closing the adsorber bed, c) extracting the air from the adsorber bed and feeding the air into the closed habitat, d) desorbing the volatile organic substances, in particular freons such as R134a and VOCs, from the adsorber bed by heating the adsorber, e) leading the desorbed substances to an environment outside the closed habitat, wherein water vapor, water, or CO2 is fed to the adsorber bed through a flushing line. The device includes a housing for accommodating an adsorber, a contained-air supply line, a contained-air return line, a flushing line, and least one outlet-air line for returning air from the adsorber bed into the closed habitat and for conducting the desorbate to an environment outside the closed habitat.

  • Patent number: 8404024
    Abstract: During the conventional temperature swing adsorption (TSA) process, NF3 co-adsorbed with the impurities is vented during regeneration. This invention is a novel TSA cycle in which the co-adsorbed NF3 is recovered. In this novel TSA cycle, a control scheme is used to stop the adsorption prior to the saturation of the adsorber with impurities and use a recovery purge gas (either co-current or counter-current) to release the co-adsorbed NF3 off the saturated adsorber. The effluent of the inert purge gas can be combined with the effluent of the on-stream vessel or can be recycled to the feed of the on-stream vessel. 10%-100% of the co-adsorbed NF3 is recovered and made available as product in this novel TSA cycle. Thus the overall process yield of NF3 is increased. The removing of the co-adsorbed NF3 from the adsorber also prevents adsorber degradation thus prolonging the useful life of the adsorber.

  • Patent number: 8273153
    Abstract: The method allows liquefaction of a dry natural gas comprising water and heavy hydrocarbons containing more than five carbon atoms. The following stages are carried out: a) passing the dry natural gas through a water-adsorbent solid so as to obtain a water-depleted natural gas and a water-laden adsorbent solid, b) passing the water-depleted natural gas through a solid adsorbing heavy hydrocarbons comprising at least five carbon atoms so as to obtain a heavy hydrocarbon-depleted natural gas and a heavy hydrocarbon-laden adsorbent solid, c) liquefying the heavy hydrocarbon-depleted natural gas at a pressure above 40 bar abs so as to obtain a liquid natural gas under pressure, d) expanding the liquid natural gas under pressure obtained in stage c) to atmospheric pressure so as to obtain a liquid natural gas and a gas fraction.

  • Publication number: 20120160098
    Abstract: A carbon dioxide (CO2) removal system includes first and second sorbent beds, a heat exchange system and means for reducing pressure. The sorbent beds each have a solid amine sorbent for adsorbing and desorbing CO2. At a given time, one of the sorbent beds adsorbs CO2 and the other sorbent bed desorbs CO2. The heat exchange system cools the CO2 adsorbing bed and heats the CO2 desorbing bed so that the temperature of the CO2 desorbing bed is greater than the temperature of the CO2 adsorbing bed. The means for reducing pressure reduces CO2 pressure at the CO2 desorbing bed. A method for removing CO2 includes supplying a gas stream to a sorbent bed containing a solid amine sorbent to adsorb CO2, reducing pressure at another sorbent bed to desorb CO2, heating the CO2 desorbing bed, cooling the CO2 adsorbing bed, and removing CO2 from the CO2 desorbing bed.
