  2. Bubble column reactor - Wikipedia

    en.wikipedia.org/wiki/Bubble_column_reactor

    A bubble column reactor is a chemical reactor that belongs to the general class of multiphase reactors, which consists of three main categories: trickle bed reactor (fixed or packed bed), fluidized bed reactor, and bubble column reactor. [1] A bubble column reactor is a very simple device consisting of a vertical vessel filled with water with a ...

  3. Fischer–Tropsch process - Wikipedia

    en.wikipedia.org/wiki/Fischer–Tropsch_process

    The Fischer–Tropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts, typically at temperatures of 150–300 °C (302–572 °F) and pressures of one to several tens of atmospheres.

  4. Plug flow reactor model - Wikipedia

    en.wikipedia.org/wiki/Plug_flow_reactor_model

    The plug flow reactor model (PFR, sometimes called continuous tubular reactor, CTR, or piston flow reactors) is a model used to describe chemical reactions in continuous, flowing systems of cylindrical geometry. The PFR model is used to predict the behavior of chemical reactors of such design, so that key reactor variables, such as the ...

  5. Fluid catalytic cracking - Wikipedia

    en.wikipedia.org/wiki/Fluid_catalytic_cracking

    Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products. [1][2][3] The cracking of petroleum hydrocarbons was originally done by thermal cracking, now ...

  6. Stripping (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Stripping_(chemistry)

    An example of a bubble cap tray that could be found inside of a stripping column. Stripping is mainly conducted in trayed towers (plate columns) and packed columns, and less often in spray towers, bubble columns, and centrifugal contactors. [2] Trayed towers consist of a vertical column with liquid flowing in the top and out the bottom.

  7. Ebullated bed reactor - Wikipedia

    en.wikipedia.org/wiki/Ebullated_Bed_Reactor

    Ebullated bed reactors are a type of fluidized bed reactor that utilizes ebullition, or bubbling, to achieve appropriate distribution of reactants and catalysts.The ebullated-bed technology utilizes a three-phase reactor (liquid, vapor, and catalyst), and is most applicable for exothermic reactions and for feedstocks which are difficult to process in fixed-bed or plug flow reactors due to high ...

  8. Flue-gas desulfurization - Wikipedia

    en.wikipedia.org/wiki/Flue-gas_desulfurization

    The G. G. Allen Steam Station scrubber (North Carolina) Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration, petroleum refineries, cement and lime kilns.

  9. Fluidized bed reactor - Wikipedia

    en.wikipedia.org/wiki/Fluidized_bed_reactor

    Fluidized bed reactor. A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst) at high enough speeds to suspend the solid and cause it to behave as though ...
