  • Publication number: 20130017144
    Abstract: A method and apparatus for processing a sour gas rich in carbon dioxide in a Claus process, so sulfur compounds are removed by a selective solvent in a gas scrubbing process. Sulfur components and carbon dioxide, are separated into at least two sour gas fractions, wherein at least one sour gas fraction having a higher content of sulfur components is obtained, wherein the fraction having the highest hydrogen sulfide content is introduced in the thermal reaction stage of the Claus furnace with a gas containing oxygen by means of a burner. The sulfur is converted to sulfur dioxide in the thermal reaction stage of the Claus furnace and exhaust gases are discharged into the closed Claus reaction chamber behind the burner. The remaining sour gas fractions stripped of sulfur components are fed to the Claus reaction chamber and are mixed with the combustion gases leaving the burner.

    Abstract: A device for condensing, separating, and storing sulfur in a Claus plant. having a Claus furnace, waste heat boiler, and Claus reactor. Plant parts are supported on a floor or comparable device, and an immersion chamber is provided below the Claus plant and optionally also below a device arranged upstream for gas scrubbing. The immersion chamber receives the sulfur in a siphoning manner, wherein the excess sulfur flows at least 4.00 meters deeper from the immersion chamber into a ground-level container in which the immersion chamber is arranged. The invention further relates to a method, by means of which liquid sulfur is conducted into an immersion chamber, wherein the immersion chamber is arranged at a height level below the waste heat boiler and the Claus reactor so that the liquid sulfur reaches the immersion chamber without further pumping and overcomes a height difference of at least 4.00 meters.

  • Publication number: 20120312678
    Abstract: A method for coking coals having high driving pressure properties in a “non-recovery” or “heat-recovery” coking oven, wherein a coking oven battery which is composed of coking oven chambers arranged side by side is used for cyclic coking of coal, and wherein an amount of coal preheated to a high temperature is admitted into the coking chamber that is to be filled at such a level that the driving pressure resulting from the coking can escape over the coke cake into the gas chamber, in such a manner that the coking oven chamber wall surrounding the coking oven chamber is relieved by the driving pressure resulting from the coking. Also disclosed is a device with which this method can be carried out.

  • Publication number: 20120298920
    Abstract: With a method for the gasification of a biomass in a fluidized bed, wherein the biomass is first pre-dried and passed to the fluidized bed gasifier, subsequently the raw gas from the gasifier impacts a recirculation cyclone and subsequently at least one raw gas cooler, the yield of such a method of procedure is supposed to be improved and the system costs are supposed to be lowered. This is achieved in that the dusts that occur in the hot gas filter that follows the raw gas cooler are recirculated into the introduction system of the biomass.

  • Publication number: 20120279394
    Abstract: A method and apparatus for drying a natural gas or an industrial gas that contains acidic gas components, wherein gas drying is followed by the removal of the acidic gas components from the dried gas. The same physical solvent is used for both of the process steps of gas drying and of acidic gas removal. The gas to be dried is brought into contact with the physical solvent, which absorbs most of the water contained in the gas. The physical solvent, loaded with water, is transferred into a solvent regenerating device to be heated where the water contained in the solvent is stripped from the solvent in the countercurrent by acidic gas that is removed from the dried useful gas during the acidic gas absorption. The acidic gas being released again in the acidic gas solvent regenerating device, stripped from the solvent, and discharged from the solvent regenerating device.

  • Patent number: 8303904
    Abstract: With the help of a fixing device for catalyzer particles, wherein the catalyzer particles are packed in a bed which can be passed through by a gas flow in the direction of gravity, it is intended to achieve a minimum specific pressure loss which will remain low even if dirt should arise from the operating process; a fixing device which has a minimum influence on the period of presence of the gas flowing through; which ensures the reliable hold-down of the catalyzer particles even at high approach velocities; and which is flexible to a certain degree in order to adapt to bed changes. This is achieved by placing at least one layer of a metal braiding on the packed bed of the catalyzer particles, and the metal braiding consisting of individual metal braiding elements which are firmly braided together.

  • Patent number: 8303684
    Abstract: A pressurized gaseous mixture acidic gas and a useful gas is directly in a first absorption column with a physically acting absorption agent. Then the absorption agent loaded with the acid gas and useful gas is subdivided into first and second streams. The first stream is fed directly to a recycle flash container and there decompressed to reclaim the useful gas, extract the acidic gas from the absorption agent, and form a recycled gas containing the useful gas and acidic gas. The second stream is through a second absorption column to the recycle flash container. Some of the recycled gas from the recycle flash container is compressed and fed through the second absorption column so as to therein directly contact the second stream, and then the recycle gas that has passed through the second absorption column and contacted the second stream is returned to the gaseous mixture.

  • Publication number: 20120272824
    Abstract: A process for the drying of gases which are routed through two or more gas coolers connected in series. The coolers being supplied with a solvent stream absorbing water from the gas entering the respective cooler, with a mixed stream consisting of gas and solvent entering each of these gas coolers, then being routed through the respective cooler and, after joint cooling in the respective cooler, being separated by a gas/liquid separator in the outlet of the respective cooler into a gas stream of reduced water content and a solvent stream laden with water. The water content of the gas is successively reduced from the first cooler to the last cooler and the solvent stream separated and laden with water being either used as feed stream for the upstream cooler or directly returned to the solvent regeneration unit where the water-enriched solvent is again freed from water.

  • Publication number: 20120247939
    Abstract: A method for extracting flue gases from a coke oven chamber, wherein the flue gases that develop briefly during the process of discharging and charging the coke cake from and to the coke oven chamber are extracted by a vacuum generated in the headspace above the coke cake. The vacuum in the headspace above the coke oven chamber is generated via channels through the lateral walls of the coke oven chamber or in the coke cake. The vacuum is generated in the secondary heating chamber and, by way of example, can be extracted again from a vacuum supply tank which, for the time that the coke oven chamber doors are open, is connected to the secondary heating chamber by opening shut-off devices in the connecting line. The method avoids the undesirable emission of flue gases into the atmosphere. A device whereby the method can be carried out is also disclosed.
