  • Patent number: 9957452
    Abstract: A method for treating a synthesis gas from a gasification step. The synthesis gas is cooled to condense heavy organic impurities and water. At the end of the cooling step, light organic impurities and inorganic impurities are adsorped by at least one adsorption bed. The water and heavy tars are separated by decantation from the step of cooling the synthesis gas. At least one adsorption bed is regenerated by temperature-modulated or pressure-modulated desorption.

  • Patent number: 9610534
    Abstract: Disclosed are methods for removing acid gas from a feed stream of natural gas including acid gas, methane and ethane. The methods include alternating input of the feed stream between at least two beds of adsorbent particles comprising zeolite SSZ-13 such that the feed stream contacts one of the at least two beds at a given time in an adsorption step and a tail gas stream is simultaneously vented from another of the at least two beds in a desorption step. The contact occurs at a feed pressure of from about 50 to about 1000 psia for a sufficient period of time to preferentially adsorb acid gas from the feed stream. A product gas stream is produced containing no greater than about 2 mol % carbon dioxide and at least about 65 mol % of methane recovered from the feed stream and at least about 25 mol % of ethane recovered from the feed stream. The feed stream is input at a feed end of each bed. The product gas stream is removed from a product end of each bed.

  • Patent number: 8888895
    Abstract: A method for the removal of H2O and CO2 from a gaseous stream comprising H2O and CO2, such as a flue gas. The method initially utilizes an H2O removal sorbent to remove some portion of the H2O, producing a dry gaseous stream and a wet H2O removal sorbent. The dry gaseous stream is subsequently contacted with a CO2 removal sorbent to remove some portion of the CO2, generating a dry CO2 reduced stream and a loaded CO2 removal sorbent. The loaded CO2 removal sorbent is subsequently heated to produce a heated CO2 stream. The wet H2O removal sorbent and the dry CO2 reduced stream are contacted in a first regeneration stage, generating a partially regenerated H2O removal sorbent, and the partially regenerated H2O removal sorbent and the heated CO2 stream are subsequently contacted in a second regeneration stage.

  • 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: 8685146
    Abstract: Processes and apparatuses are provided for preparing liquified natural gas from a natural gas feed that comprises C5 to C7 hydrocarbons and C8 or greater hydrocarbons. An exemplary process includes effecting the preferential adsorption of the C8 or greater hydrocarbons from the natural gas feed over adsorption of hydrocarbons having less than 8 carbon atoms to provide a C8-depleted natural gas stream. The process continues with effecting the preferential adsorption of the C5 to C7 hydrocarbons from the C8-depleted natural gas stream over adsorption of hydrocarbons having less than 5 carbon atoms to form a C5 to C8-depleted natural gas stream. The C5 to C7 hydrocarbons are preferentially adsorbed with higher selectivity and capacity than adsorption of the C5 to C7 hydrocarbons during preferentially adsorbing the C8 or greater hydrocarbons. The C5 to C8-depleted natural gas stream is then liquified.

  • Patent number: 8685175
    Abstract: An apparatus and process for isomerizing a hydrocarbon stream rich in a C4 hydrocarbon and/or at least one of a C5 and C6 hydrocarbon which includes a first drier and a second drier; and a reaction zone communicating with at least the first drier. The first drier operates at a first condition to dry the reactant and the second drier operates at a second condition during regeneration. The used regenerant remaining in the second drier after regeneration can (1) pass through a vent-to-flare assembly in a batch-wise manner; (2) pass through a downflow-depressure-to-low-pressure-device assembly in a batch-wise manner; (3) pass through a cross-over piping purge assembly to minimize upsets in the reaction and fractionation zones when the second drier is placed back in operation; or any combination of (1) (2) and/or (3) to minimize upsets in the reaction and fractionation zones when the second drier is placed back in operation.

  • Patent number: 8591627
    Abstract: Disclosed herein is a method and system for separating carbon dioxide (CO2) from a CO2 containing gas stream containing water vapor and additional impurities, for example, nitrogen, oxygen, sulfur oxides, nitrogen oxides, and mercury. The CO2 is captured by subjecting the CO2 gas feed stream to a temperature swing adsorption step. The temperature swing adsorption step comprises an adsorption step for producing a substantially dry carbon dioxide-depleted stream, and an adsorbent regeneration step comprising heating the adsorbent bed to produce a substantially water vapor-free carbon dioxide stream. Moisture from the gas stream containing CO2 is optionally removed by pressure swing adsorption, temperature swing adsorption, membrane separation, or absorption prior to CO2 capture.
