摘要： Processes for the thermal reduction of sulfur dioxide to elemental sulfur are described and disclosed. The processes described include three general reaction sections, including the reaction furnace portion where the S02-containing stream is combusted, the second reaction zone where the temperature is moderated to encourage the reaction of sulfur with hydrogen to consume the hydrogen carbon monoxide and produce the H2S and CO with allowing adequate residence time. The temperature moderation is achieved by one or combinations of three different methods including adding external waste heat boiler, using inter-stage internal cooling coil or adding a quench fluid. The third reaction zone is a Claus conversion portion, wherein residual H2S and S02 are further reacted to produce additional elemental sulfur in one or more reactors containing Claus type catalyst or combination of them.

摘要： This disclosure relates generally to processes for efficient incineration and conversion of the tail gas streams from sulfur recovery units containing sulfur compounds such as H2S, CO2, COS, CS2, and other sulfur species and sulfur vapors from S1 to S8 to SO2. The present disclosure describes the use of a combination of catalysts to achieve efficient oxidation of all reduced sulfur compounds as well as oxidation of CO and H2 to meet the industry emission requirements. The catalytic tail gas incineration process described herein can advantageously operate at lower temperatures, which in turn can represent a savings in reduced fuel gas costs.
摘要翻译：本公开总体上涉及有效焚烧和转化来自含硫化合物例如H 2 S，CO 2，COS，CS 2和其它硫物质的硫回收单元的尾气流从S1转移到S8至SO2的方法。本公开描述了使用催化剂的组合来实现所有还原的硫化合物的有效氧化以及CO和H 2的氧化以满足工业排放要求。本文所述的催化尾气焚烧方法可以有利地在较低的温度下运行，这反过来又可以节省降低的燃料气体成本。

摘要： The reduction of gas streams containing sulfur dioxide to elemental sulfur is carried out by contacting a reducing gas, such as natural gas, methanol or a mixture of hydrogen and carbon monoxide, with recycled sulfur to produce a stream containing hydrogen sulfide that may be reacted with the gas stream that contains sulfur dioxide. Gas streams with a molar concentration of sulfur dioxide from 1 to 100% may be processed to achieve nearly 100% sulfur recovery efficiency.
