    • 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 H 2 S 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.
    • 在水平硫冷凝器内产生脱气的液体硫的方法可包括将引入冷凝管的Claus工艺气体的一部分冷凝以产生液态硫; 在具有挡板的液体硫储存器上方形成第一和第二室; 将液态硫和克劳斯处理气体通入第一室; 迫使克劳斯处理气体从第一室内的液体储存器到第二室; 导致液体硫中的溶解硫化氢与来自Claus工艺气体的二氧化硫在催化剂上的化学反应,以产生元素硫并降低其余硫的溶解H2S含量; 通过克劳斯反应转化硫化氢; 将硫化氢分解成硫化氢和硫,从硫化氢中释放元素硫; 迫使克劳斯工艺气体从液体储存器进入液体储存器上方的第二室。
