  • Coke Plant Scrubber Water Case Study

    Challenge For the production of coke, volatile constituents of the coal —including water, coal-gas, and coal-tar— are driven off by baking in an airless furnace at temperatures as high as 2.000 °C. The flue gas goes through an ammonia-based scrubbing process. The resulting scrubber water contain small coal-tar and other organic particles (1-250 micron) that cause scaling in ...

  • Case study - Reactor vent emission control

    OVERVIEW Many chemical and petroleum companies use batch reactors to make their products.  These reactors typically have vents which are opened and closed during emptying, filling, mixing, heating or cooling and other steps of the production process.  The gases coming from these vents must be controlled under most government regulations.  Generally speaking, the ...

  • Catalytic reduction of nitrate in secondary effluent of wastewater treatment plants by Fe0 and Pd–Cu/γ–Al2O3

    Total nitrogen, in which NO3− is dominant in the effluent of most wastewater treatment plants, cannot meet the requirements of the Chinese wastewater discharge standard (<15 mg/L), making nitrate (NO3−) elimination attract considerable attention. In this study, reductant iron (Fe0) and γ–Al2O3 supported palladium–copper bimetallic ...
