  • Patent number: 8940077
    Abstract: A method for indirectly monitoring and controlling an electrically resistive adsorption system. Adsorption of a predetermined adsorbate is conducted while indirectly monitoring electrical resistance of a unified adsorbent element. Breakthrough is predicted based upon the indirectly monitored electrical resistance and a previously measured mass loading relationship between the resistance of the unified adsorbent element and the loading of the unified resistance element with the predetermined adsorbate. Adsorption, regeneration and cooling cycles are controlled by a controller without any direct measurement of temperature or resistance of the element and characterizations of mass loading and temperature. Systems of the invention can have no sensors that contact the element, are in an adsorption vessel, and/or are downstream adsorption vessel.

  • Patent number: 8709135
    Abstract: An off gas extraction system cleans common sources of off gas, such as storage tanks and polluted soils. Off gas is extracted, followed by compression and condensation. Compression and condensation produce an off gas that can be reintroduced as a treated gas into the off gas source. Alternatively, a regenerative absorber cleans the treated gas by adsorbing residual chemical vapor and concentrates the removed chemical vapors and reprocesses them. If the treated gas is not reintroduced into the off gas source, conventional scrubbers may used on the back end of the system to produce a final exhaust as prescribed by environmental regulation. Methods of accomplishing the same are similarly provided, including novel methods for degassing storage tanks and treating polluted soils to meet current environmental regulations, as well as green technology and sustainability initiatives.

  • Patent number: 8679229
    Abstract: An adsorbent comprising a zeolite having a pore diameter of not less than 4.5 angstroms and not more than 7.3 angstroms as a principal component, which can adsorb xenon under ordinary temperatures and pressures or under ordinary temperatures and low xenon partial pressure, is used. In the xenon recovery method of the present invention, the adsorbent is communicated with a xenon-containing equipment, and xenon is adsorbed on the adsorbent and xenon is detached from the adsorbent. Thereby, xenon can be recovered, with efficiency, directly from used equipment in which xenon is enclosed under ordinary temperatures and pressures or under ordinary temperatures and low xenon partial pressure.

  • Patent number: 8679231
    Abstract: A polyvinylidene fluoride (PVDF) pyrolyzate adsorbent is described, having utility for storing gases in an adsorbed state, and from which adsorbed gas may be desorbed to supply same for use. The PVDF pyrolyzate adsorbent can be of monolithic unitary form, or in a bead, powder, film, particulate or other finely divided form. The adsorbent is particularly suited for storage and supply of fluorine-containing gases, such as fluorine gas, nitrogen trifluoride, carbo-fluoride gases, and the like. The adsorbent may be utilized in a gas storage and dispensing system, in which the adsorbent is contained in a supply vessel, from which sorbate gas can be selectively dispensed.

  • Patent number: 8668767
    Abstract: Various equipment and methods associated with providing a concentrated product gas are provided. In one embodiment, the equipment includes an input device first and second sieve tanks, a variable restrictor, and a controller. In one embodiment, the method includes: a) selecting a desired output setting for the concentrated product gas from a plurality of output settings, b) separating one or more adsorbable components from a pressurized source gaseous mixture via first and second sieve tanks in alternating and opposing pressurization and purging cycles to form the concentrated product gas, and c) selectively controlling a variable restrictor based at least in part on the desired output setting to selectively provide flow between the first and second sieve tanks such that the flow for at least one output setting is different from the flow for at least one other output setting in relation to corresponding pressurization cycles.

  • Publication number: 20140060326
    Abstract: The invention relates to an increased efficiency high-capacity pressure and/or temperature swing adsorption process comprising: contacting a feedstream at a rate of more than 75 MSCFD with an adsorbent material under conditions sufficient for the adsorbent material to selectively adsorb at least one of the component gases in the feedstream, so as to form a first effluent; and selectively desorbing the adsorbed gas from the adsorption material, so as to form a second effluent The adsorption module can contain rotary valves both on the feed end and on the product end and a rotational member defining a central rotational axis, with the adsorption bed(s) oriented circumferentially thereto. The adsorption bed walls can be angled, the feed end cross-sectional area of the adsorption bed(s) can be larger than the product end, and/or the feed end rotary valve diameter of the module(s) can be larger than the product end.

  • 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: 8636829
    Abstract: The invention provides gas purification systems for the recovery and liquefaction of low boiling point organic and inorganic gases, such as methane, propane, CO2, NH3, and chlorofluorocarbons. Many such gases are in the effluent gas of industrial processes and the invention can increase the sustainability and economics of such industrial processes. In a preferred system of the invention, low boiling point gases are adsorbed with a heated activated carbon fiber material maintained at an adsorption temperature during an adsorption cycle. During a low boiling point desorption cycle the activated carbon fiber is heated to a desorption temperature to create a desorption gas stream with concentrated low boiling point gases. The desorption gas stream is actively compressed and/or cooled to condense and liquefy the low boiling point gases, which can then be collected, stored, re-used, sold, etc.
