  • Patent number: 10843125
    Abstract: With the invention a washing apparatus and a process for the efficient separation and recovery of methanol from waste gases loaded with methanol is proposed, wherein the invention also can be used in an integrated flow chart for the production and processing of methanol. The methanol fractions separated from the waste gases are recovered within the already existing, distillative processing of the crude methanol to pure methanol, so that no separate apparatuses are required for the recovery of the methanol from the loaded scrubber waste waters. The valuable substance methanol is recovered and the impact on the environment is reduced. By particular aspects of the invention the total degree of methanol separation can be adapted according to the locally applicable emission limit values.

  • Patent number: 10758861
    Abstract: The method includes limiting saturation of output absorbent with dispersed and recirculating gas molecules with full completion of chemical reactions in the first stage, countercurrent contact between the gas and absorbent in the loading elements of the nozzle in the second stage, further extraction of gas molecules by absorbent in the irrigation chamber of the third stage. Then the gas for the absorption of hard-to-recover components is transferred to the irrigation chamber of the fourth stage, where it is irrigated with fine droplets of fresh and circulating absorbent. Then the direct-flow contact between the gas-liquid phase is carried out in the checker loading elements of the fifth stage. Finally, interphase contact of depleted gas with absorbent is completed in the bubbling chamber of the sixth stage and in the interchamber space between the fifth and sixth chambers.

  • Patent number: 10377629
    Abstract: A method of safely vaporizing liquid chlorine containing high concentrations of nitrogen trichloride contaminant from a chloralkali plant. In a vertical plug-flow vaporizer having an upward flow direction, a stream of liquid chlorine containing nitrogen trichloride is received. A gas such as air, nitrogen or chlorine gas is introduced into the liquid stream upstream of the boiling zone of the vaporizer to induce a flow regime, for example annular flow or mist flow, that prevents a mass accumulation of nitrogen trichloride in the vaporizer. The liquid chlorine containing nitrogen trichloride is vaporized. The resulting gas stream may be processed to destroy the nitrogen trichloride and recycled to the chlorine production train.

    Abstract: A moisture removal system for removing water moisture from an air stream and an associated method are provided. The moisture removal system includes one or more packed beds that include a water-entry surface at which liquid water is received and an air-entry surface that is located substantially opposite the water-entry surface and at which the air stream is received. The air stream passes through the one or more packed beds in a direction substantially counter-current to the passage of the liquid water and the liquid water and the air stream contact one another in the one or more packed beds resulting in the removal of at least a portion of the water moisture from the air stream. The moisture removal system can be located upstream of and be operably connected to the inlet of a gas turbine system to which the air stream is delivered from the moisture removal system.

  • Patent number: 8387545
    Abstract: A method for introducing flue gas in a steam-assisted production facility into a vapor-liquid contactor. In this method the flue gas comprises boiler combustion products selected from at least one of commercial pipeline natural gas and produced gas. The flue gas is cooled with the vapor-liquid contactor to condense a portion of the water vapor in the flue gas to produce a water stream. The water stream is then recirculated and cooled in an air cooler to produce recirculating water exiting the bottom of the vapor-liquid contactor. A water slipstream is then taken off the recirculating water to be used as make-up water.

  • Patent number: 8353980
    Abstract: An apparatus and process for removing acidic gases from flue gases produced by, for example, utility and industrial facilities. The acidic gases are removed as the flue gas flows upward through a contact zone within a passage, where the flue gas is contacted with an ammonium sulfate-containing scrubbing solution to absorb the acidic gases from the flue gas. The scrubbing solution and absorbed acidic gases therein are then accumulated, and ammonia and an oxygen-containing gas are injected into the accumulated scrubbing solution to react the absorbed acidic gases and produce ammonium sulfate. An acid solution is flowed across the passage above the contact zone of the passage, and the scrubbed flue gas is flowed upward through the acid solution to remove unreacted ammonia from the scrubbed flue gas. The acid solution is then removed from the passage after the acid solution has been contacted by the scrubbed flue gas.

  • Patent number: 8343256
    Abstract: An integrated contaminant separator and water-control loop (10) decontaminates a fuel reactant stream of a fuel cell (12). Water passes over surfaces of an ammonia dissolving means (61) within a separator scrubber (58) while the fuel reactant stream simultaneously passes over the surfaces to dissolve contaminants from the fuel reactant stream into the water. An accumulator (68) collects the separated contaminant stream, and ion exchange material (69) integrated within the accumulator removes contaminants from the stream. A water-control pump (84) directs flow of a de-contaminated water stream from the accumulator (68) through a water-control loop (78) having a heat exchanger (86) and back onto the scrubber (58) to flow over the packed bed (62). Separating contaminants from the fuel reactant stream and then isolating and concentrating the separated contaminants within the ion exchange material (69) minimizes cost and maintenance requirements.

  • Patent number: 8292272
    Abstract: Water is separated from a liquid mixture (e.g., sea water) using a humidification chamber and a dehumidification chamber that are each operated at a pressure less than ambient atmospheric pressure (e.g., at least 10% less than ambient atmospheric pressure). A carrier gas is flowed through the humidification chamber; and inside the humidification chamber, the carrier gas directly contacts the liquid mixture to humidify the carrier gas with water evaporated from the liquid mixture to produce a humidified gas flow. The humidified gas flow is directed through the dehumidification chamber, where water is condensed from the humidified gas flow and collected.
