  • Publication number: 20150075072
    Abstract: Devices for a three-stage scrubbing system for treatment of hot crude gases and liquid slag by an entrained flow gasification. Crude gas and slag are conducted downward into a water bath in a central tube. The upper part of the central tube consists of a double-threaded tube screen welded in a gas-tight manner, in which water is injected directly as the first scrubbing and cooling stage in the interior thereof. In the water bath, a bubble column is formed, which simultaneously constitutes the second scrubbing and cooling stage. Surface bodies arranged in three layers increase the scrubbing effect. After leaving the bubble column, the crude gas is again sprayed with water in a cavity, wherein one or more nozzle rings are disposed. This forms the third scrubbing stage. The crude gas then leaves the quenching and scrubbing apparatus in steam-saturated form at 200-220° C. and is sent to further treatment.

    Abstract: A three-stage quenching and scrubbing system for treatment of hot crude gases and liquid slag after an entrained flow gasification. In the first primary stage, cooling and scrubbing water is injected such that slag can no longer adhere to the wall of the central tube and the conversion reaction of the carbon monoxide with water vapor to give hydrogen can proceed to close to the equilibrium. A secondary quenching and scrubbing stage takes the form of a bubble column, and further cooling and the deposition of coarse dust and slag are effected in a water bath. The rest of the treatment is through intensive spraying in a tertiary quenching and scrubbing the gas stage, nozzle rings for deposition of fine slag and partly of fine dust. All three quenching and scrubbing stages enable cooling of the crude gas down to the water vapor dew point determined by the plant pressure.

  • Patent number: 8969422
    Abstract: A gasification-liquefaction disposal method, system and equipment for MSW are disclosed. The method involves the MSW pretreatment of dehydrating and separating, thus reducing water and inorganic substance content of the waste. Then, the MSW is introduced into a plasma gasifier (23) by a carbon dioxide air-sealed feeding device (13) and gasified therein to obtain hydrogen-rich syngas. The hydrogen-rich syngas is then cooled, deacidified, dedusted and separated to obtain carbon dioxide. Then, the hydrogen-rich syngas is catalyzed to produce methanol product in a methanol synthesis reactor (52). The separated carbon dioxide is sent back to a carbonation reaction chamber (2007) of a gasification system to perform carbonation reaction with calcium oxide, thereby releasing heat to provide assistant heat energy for gasification and avoiding greenhouse gas from being discharged into environment.

  • Publication number: 20130320258
    Abstract: The use of a composition that includes a metal salt and an oil soluble amine formaldehyde reaction product scavenges H2S that is present in aqueous fluids (e.g. produced water liquid streams), natural gas and in oil and mixtures thereof (e.g. mixed production streams that contain all three phases) better than either component when used alone. The resulting scavenger combination significantly increases the reaction rate and the overall scavenging efficiency, i.e. capacity over each component when used alone, in the same total amount. Non-limiting examples of the metal salt include zinc or iron carboxylates, and a non-limiting example of an oil soluble amine formaldehyde reaction product is the reaction product of dibutylamine with formaldehyde.

  • Patent number: 8551416
    Abstract: A method and system for recovering CO2 from gasification gas, prevents the recovered CO2 from being contaminated with COS, without repeating cooling and heating operations and without increasing the steam consumption. Gasification gas being produced in a gasifier 10 and containing CO, CO2, COS and H2S is subjected to dust removal in a scrubber 20. Then, a part of the gas is subjected to a CO shift reaction, in which CO is converted into CO2, in a CO shift reactor 30. In one embodiment, part of the gasification gas is not subjected to the CO shift reaction by means of a bypass 34, and is mixed with the gas after the CO shift reaction. Thereby, the temperature of the mixture gas is set at 180° C. to 300° C., and COS in the mixture gas is converted into H2S in a COS converter 40.

  • Publication number: 20130255153
    Abstract: Disclosed is a method of gas purification, a coal gasification plant, and a shift catalyst, each of which enables an inexpensive treatment of condensed water derived from steam used in a CO shift reaction. A CO shift reaction is performed using a shift catalyst less causing side reactions (e.g., a P—Mo—Ni-supported shift catalyst), and condensed water derived from steam used in the CO shift reaction is reused or treated. The method includes a cleaning step of removing water-soluble substances from a gasified gas containing CO and H2S; a CO shift step of allowing CO in a gas after the cleaning step to react with steam by the catalysis of the shift catalyst to convert CO into CO2 and H2; and a recovery step of removing CO2 and H2S from a gas after the CO shift step, in which post-shift condensed water formed after the CO shift step is recycled.
