摘要：
PURPOSE: Provided is a process for treating caustic waste or spent streams containing sulfur compounds with a packed column recycle reactor for the oxidation of the sulfur compounds in the waste stream. CONSTITUTION: A common post-refining sulfur-removal method is caustic washing in which the hydrocarbon streams are contacted with concentrated solutions of caustic soda. The caustic soda reacts with hydrogen sulfide to form sodium sulfide and with mercaptans to form sodium mercaptides. The caustic stream loaded with the above compounds is called spent caustic. A typical spent caustic stream from a refinery contains as much as 10 to 170 g/l of sodium sulfide, 100-1000 ppm of mercaptans and traces of phenols and disulfides.

目的：提供一种处理含有硫化合物的苛性废物或废料流的方法，其中填充塔循环反应器用于氧化废物流中的硫化合物。 构成：通常的精炼后脱硫方法是苛性洗涤，其中烃流与苛性钠的浓缩溶液接触。 苛性钠与硫化氢反应形成硫化钠和硫醇形成硫醇钠。 装载上述化合物的苛性流被称为废碱。 来自炼油厂的典型废碱液含有多达10至170g / l的硫化钠，100-1000ppm的硫醇和痕量的酚和二硫化物。
