  • Patent number: 10371441
    Abstract: A mixed phase pressurized unstabilized hydrocarbon stream is fed into a stabilizer column at a feed pressure. A liquid phase of stabilized hydrocarbon condensate is discharged from a bottom end of the stabilizer column, while a vapor phase of volatile components from the pressurized unstabilized hydrocarbon condensate stream is discharged from a top end of the stabilizer column. The vapor phase being discharged from the top end of the stabilizer column is compressed and subsequently passed through an ambient heat exchanger wherein partial condensation takes place. The resulting partially condensed overhead stream is separated in an overhead separator into a vapor effluent stream and an overhead liquid stream. After discharging the overhead liquid stream from the overhead separator, it is selectively divided into a liquid reflux stream and a liquid effluent stream. The liquid reflux stream is expanded to the feed pressure and fed into the stabilizer column.

  • Patent number: 9452386
    Abstract: CO2 may be recovered from flue gas by a hybrid system utilizing both gas separation membranes and adsorption. Purified flue gas is separated by the gas separation membrane into permeate and non-permeate streams. The permeate stream is compressed, partially condensed at a heat exchanger, and phase-separated to produce a vent gas and high purity liquid CO2. The vent gas is recycled to the membrane. The non-permeate is fed to a PSA unit. The CO2 blow-down from the PSA unit is also compressed with the flue gas stream. The adsorbent in the PSA unit is regenerated with combustion air and the CO2-containing combustion air is fed to a combustor for combustion with fuel and an oxidant to produce the flue gas.

  • Publication number: 20150114032
    Abstract: Impurities that are less volatile than carbon dioxide, e.g. hydrogen sulfide, are removed from crude carbon dioxide by processes involving distillation of said crude carbon dioxide in a distillation column system operating at super-atmospheric pressure(s) to produce carbon dioxide-enriched overhead vapor and bottoms liquid enriched with said impurities. Where such processes involve a single heat pump cycle, significant savings in power consumption are realized when the distillation column system is re-boiled by at least partially vaporizing liquid in or taken from an intermediate location in the column system.

  • 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: 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.

  • Patent number: 8590339
    Abstract: In method of providing uniformity of vapor and liquid phases in two or more streams derived from a mixed vapor and liquid stream (10), the mixed vapor and liquid stream (10) passes from a first heat exchanger (101) into a distribution vessel (12) via one or more inlets (14). The distribution vessel (12) has two or more outlets (16) connected to a second heat exchanger (102). The liquid part of the mixed stream (10) is allowed to collect in a first area (20) in the distribution vessel (12), and the vapor part of the mixed stream (10) is allowed to collect in a second area (30) of the distribution vessel (12), preferably above the first area (20). The liquid in the first area (20) passes into the outlets (16) via one or more liquid apertures (18) in each outlet (16) that communicate with the first area (20), and the vapor in the second area (30) passes into the outlets (16) via one or more vapor apertures (28) in each outlet (16) communicating with the second area (30).

  • Publication number: 20130295749
    Abstract: Methods and apparatus for recovery of precursor vapor from a gas and precursor vapor mixture used in a deposition process. The gas and precursor vapor mixture is passed through a multitude of heat transfer surfaces in a heat conducting housing causing the precursor vapor to condense. The precursor vapor in liquid form is then collected after condensation.

  • Publication number: 20130283851
    Abstract: Impurities that are less volatile than carbon dioxide, e.g. hydrogen sulphide, are removed from crude carbon dioxide by processes involving sub-ambient distillation of said crude carbon dioxide in a distillation column system operating at super-atmospheric pressure(s) to produce carbon dioxide-enriched overhead vapour and bottoms liquid enriched with said impurities. Where such processes involve at least one heat pump cycle, significant savings in power consumption are realised when the process uses more than one recycle pressure in the heat pump cycle(s).

  • Patent number: 8557024
    Abstract: An IGCC plant has a precombustion decarbonization unit in which acid gas is removed from a combustion gas before the combustion gas enters a combustion turbine. In one preferred configuration, a sulfur removal unit removes hydrogen sulfide from a feed gas before the desulfurized feed gas enters an autorefrigeration unit in which carbon dioxide is removed. In another preferred configuration, hydrogen sulfide is converted to carbonyl sulfide in a dryer, and the carbonyl sulfide is absorbed in the liquid carbon dioxide that is prepared from the feed gas using autorefrigeration.

  • Patent number: 8518149
    Abstract: Embodiments of the present disclosure include a process for the production of chlorine gas. For the various embodiments, the process includes compressing a gas mixture of vaporized liquid chlorine and a feed gas containing chlorine to form a compressed gas. Chlorine in the compressed gas is condensed into liquid chlorine. A first portion of the liquid chlorine is vaporized to provide a heat of condensation to condense chlorine from the compressed gas into liquid chlorine. A second portion of the liquid chlorine is vaporized to provide both the vaporized liquid chlorine for the gas mixture and a heat of condensation to cool a tail gas from the process. A chlorine gas product from the vaporized first portion of the liquid chlorine is also produced.

  • Patent number: 8500853
    Abstract: The invention provides gas purification methods and 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 method 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.
