    摘要: A process of producing degassed liquid sulfur within a horizontal sulfur condenser may include condensing a portion of a Claus process gas introduced into a condenser tube to produce liquid sulfur; creating first and second chambers above a liquid sulfur reservoir with a baffle; passing the liquid sulfur and the Claus process gas into the first chamber; forcing the Claus process gas from the liquid reservoir within the first chamber to the second chamber; causing a chemical reaction between dissolved hydrogen sulfide in the liquid sulfur and sulfur dioxide from the Claus process gas on a catalyst to produce elemental sulfur and reducing the dissolved H2S content of the remaining sulfur; converting hydrogen sulfide by a Claus reaction; decomposing polysulfanes to hydrogen sulfide and sulfur, freeing elemental sulfur from hydrogen sulfide; forcing the Claus process bubbles from the liquid reservoir into the second chamber above the liquid reservoir.

    摘要: The present invention provides a process for preparing ethylene and/or propylene, wherein an oxygenate feedstock is contacted with a molecular sieve-comprising catalyst at a temperature in the range of from 350 to 500° C. to obtain a reactor effluent comprising ethylene and/or propylene and the oxygenate feedstock is contacted with the catalyst in a riser reactor having a reactor wall defining a flow trajectory towards a downstream outlet for reactor effluent, wherein at least oxygenate feedstock and catalyst are provided at one or more upstream inlets of the riser reactor and wherein a water quench medium is admitted to the riser reactor at one or more of locations along the length of the flow trajectory through a plurality of inlets distributed along the periphery of the reactor wall. The invention further provides a reaction system suitable for preparing ethylene and propylene.

    摘要: The invention reduces the potential for catalyst fluidization in a reduction vessel of a continuous catalyst regeneration system. The gas exit area from the catalyst reduction zone is increased by ventilating the cylindrical baffle of the upper reduction zone. This provides an increased exit cross-sectional area for the upper reduction gas to escape and reduce the overall exit velocity of the combined upper and lower reduction gases and reduces the potential for catalyst fluidization.
