WebThe majority of methods currently in use for removing mercury from natural gas and hydrocarbon liquids employ fixed bed technologies. The main process stream flows through a fixed bed in which mercury undergoes a physical or chemical interaction with the reagent in the mercury removal vessel, producing a mercury-free product. WebArsine/mercury Adsorbent. Shell Catalysts & Technologies has designed an efficient guard bed to protect downstream catalysts from common poisons, specifically sulphur, arsine, and/or mercury. The adsorbents are designed to operate within the reaction system, at standard operating conditions, eliminating the need for the design of a separate ...

Mercury transformation and removal in roasting and/or …
WebMercury removal from hydrocarbons is crucial due to HSE-related issues, corrosion problems and downstream catalyst poisoning. It is a challenge commonly faced in natural gas processing plants, oil refineries, petrochemical industry and power plants. Webas an analytical tool to measure the mercury concentration of a contaminated gas stream. The mercury removal capacity of the newly developed adsorbent was far more effective than existing materials and was found to depend on the PdCI2 content of the inert material and the gas superficial velocity through the packed bed. Hot chlorine Web6 nov. 2024 · Used-Fe/SC120 could achieve the mercury removal efficiency of above 90% at 90 °C. The high temperature was not conducive to the mercury capture due to the release of surface elemental sulfur. The presence of O 2 and SO 2 inhibited Hg 0 removal in different degrees because of the decreased active sulfur sites and competitive … cf1020 mirolin
