    • Processes and systems associated with hydrodynamic cavitation-catalyzed oxidation of sulfur-containing substances in a fluid are described. In one example method, carbonaceous fluid is combined with at least one oxidant to form a mixture and then the mixture is flowed through at least one local constriction in a flow-through chamber at a sufficient pressure and flow rate to create hydrodynamic cavitation in the flowing mixture having a power density of between about 3,600 kWatts/cm2 and about 56,000 kWatts/cm2 measured at the surface of the local constriction normal to the direction of fluid flow. The creation of hydrodynamic cavitation in the flowing mixture initiates one or more chemical reactions that, at least in part, oxidize at least some of the sulfur-containing substances in the carbonaceous fluid. An example system includes a device configured to mix a carbonaceous fluid and one or more oxidants, at least one cavitation chamber configured to produce cavitation bubbles in the mixture, and at least one elevated pressure zone configured to collapse the cavitation bubbles, thereby catalyzing oxidation of the sulfur-containing substances.
    • 描述了与流体中含硫物质的流体动力空化催化氧化相关的方法和系统。 在一个示例性方法中,碳质流体与至少一种氧化剂组合以形成混合物,然后混合物以足够的压力和流速在流通室中流过至少一个局部收缩,以在流动中产生流体动力学空化 在与流体流动方向垂直的局部收缩部的表面处测量的功率密度为约3600kWatts / cm 2至约56,000kWatts / cm 2的混合物。 在流动混合物中产生流体动力空化引发一种或多种化学反应,其至少部分地氧化碳质流体中的至少一些含硫物质。 示例性系统包括被配置为混合碳质流体和一种或多种氧化剂的装置,至少一个空化室,其构造成在混合物中产生空化气泡;以及至少一个升高的压力区域,其构造成使空化气泡塌陷,由此催化氧化 含硫物质。
