  • Patent number: 10315159
    Abstract: A method of adsorption allows separation of a first fluid component from a fluid mixture comprising at least the first fluid component in an adsorptive separation system having a parallel passage adsorbent contactor with parallel flow passages having cell walls which include an adsorbent material. The method provides for transferring heat from the heat of adsorption in a countercurrent direction along at least a portion of the contactor during adsorption and transferring heat in either axial direction along the contactor and/or a direction transverse to the axial direction, to provide at least a portion of the heat of desorption during a desorption step. A carbon dioxide separation process to separate carbon dioxide from flue gas also includes steps transferring heat from adsorption or for desorption along the parallel passage adsorbent contactor.

  • Publication number: 20150082986
    Abstract: A process for separating methane from a natural gas mixture employs pressure swing adsorption in one or more vessels. Each vessel has an adsorbent material having a kinetic selectivity for contaminants over methane greater than 5. Contaminants within the natural gas mixture become gases kinetically adsorbed within the adsorbent material. The vessel is placed under pressure to cause contaminants to be adsorbed in the surfaces and micro-pores of the adsorbent material. The process includes releasing a product stream comprised at least 95% by volume methane from a first gas outlet in the vessel, and desorbing the contaminant gases from the adsorbent material by reducing the pressure within the vessel. The desorbing step is done without applying heat to the vessel, thereby delivering a waste gas stream comprised at least 95% by volume of the contaminant gases. An improved fractionation vessel having both major and minor flow channels is also provided.

Compression and condensation produce an off gas further treated to produce pollutant-free exhaust. A regenerative adsorber cleans the influent gas/air by adsorbing residual chemical vapor and concentrates the removed chemical vapor and reprocesses them. Conventional scrubbers are used on the back end of the system to produce a final exhaust as prescribed by environmental regulation. Methods of accomplishing the same are likewise taught including combinations and additions consistent with schemes as they evolve.

    Abstract: A system for increasing the power of cars by increasing the oxygen content in the intake manifold supply using a zeolite filtration system. This system does not rely on the conventional method of injecting pure oxygen from a tank or using hydrolysis from water. This actually converts the air to a higher oxygen content as it flows to the intake manifold in a car. The practical idea of this is to increase the power of the engine without increasing displacement or to have the engine downsized with less displacement while still having the same power. It also has the application in cars or trucks to almost completely diminish NOx emissions. This is especially useful in tractor trailers because then you can forgo expensive aftertreatment systems to reduce NOx, which sometimes cost more than the engine itself, greatly reducing the cost of a tractor trailer and also doing the things mentioned above.

  • Patent number: 8585809
    Abstract: An air dryer cartridge 100 configured for use on both conventional air dryer systems having internal purge air valving and newer air dryer systems wherein at least some of the purge air valving is located in the cartridge. The air dryer cartridge 100 has a first connector 112 for mating with a corresponding connector of a conventional air dryer system, and a second connector 156 for mating with a corresponding connector of a newer-style air dryer system. When the cartridge 100 is installed on a conventional air dryer system, purge air valving 144/146 within the cartridge is deactivated causing the cartridge to act as a conventional air dryer cartridge. When the cartridge 100 is installed in a newer-style system, the purge air valving 144/166 within the cartridge is activated thus enabling the system to function as designed.

  • Patent number: 8574347
    Abstract: The present invention relates to a pressure swing adsorption process, also known as PSA process, which is modified with a view to utilizing the heat from the post-adsorption stream coming from the molecular sieves to heat/vaporize the pre-adsorption stream containing the hydrated product or the mixture component(s) to be adsorbed in said sieves. The present invention provides alternative arrangements for the heat exchanger system in order to use the thermal potential of the post-adsorption stream with the elimination or minimization of the risk of a slug flow regime in the exchangers, the so-called “gush,” which would be a natural result from the periodic oscillation characteristic of PSA processes. With this, the vapor consumption with the modified process according to the present invention is considerably reduced.

  • Publication number: 20130263741
    Abstract: Embodiments of the invention are directed towards a trap canister for adsorbing fuel vapor contained in breakthrough gas discharged from a main adsorbent canister. The main adsorbent canister is connected to a fuel tank has a case defining an adsorption chamber therein and an adsorbent filled in the adsorption chamber. The case has a first end open to the atmosphere and a second end for introducing breakthrough gas into the adsorption chamber. The adsorbent filled in the adsorption chamber adsorbs the fuel vapor contained in the breakthrough gas. The trap canister further has a bypass path for bypassing the adsorption chamber and a valve configured to block the bypass path and to allow for opening during refueling. This prevents the fuel vapor from flowing into the atmosphere during normal operation while also decreasing pressure loss during refueling.
