An apparatus for performing continuous flow chemical reactions such as oxidation, oxidative dehydrogenation and partial oxidation processes involving a reactor design characterized by controlled/optimized addition of a reactant with the objective of: (i) avoiding the explosion regime of the reactant mixture (e.g., hydrocarbon/oxidant mixture); (ii) maximizing the selectivity of the reaction to the desired product; (iii) limiting the reactor temperature gradient and therefore the threat of reaction runaway; and (iv) controlling the operating temperature of the reaction zone so that desirable temperature range is maintained over the entire zone.
A continuous flow chemical reaction apparatus comprising a tubular reaction zone having a length and having a first fluid feed inlet at a first end and a product outlet at a second end, said tubular reaction zone having an interior conduit extending lengthwise within said tubular reaction zone, said conduit having a second fluid feed inlet and a multiplicity of injectors spaced apart along the length of said conduit, each of said injectors capable of introducing a controlled amount of a second fluid reactant into said tubular reaction zone, and at least one of said injectors having a pressure drop control means in said conduit proximate to said injector.
A continuous flow chemical reaction apparatus comprising a plurality of tubular reaction zones within a heat transfer vessel having at least one heat transfer zone, each of said heat transfer zones having a heat transfer fluid inlet and a heat transfer fluid outlet, each of said tubular reaction zones having a length, a first fluid feed inlet at a first end, a product outlet at a second end and an interior conduit extending lengthwise within said tubular reaction zone, said interior conduit having a second fluid feed inlet and a multiplicity of injectors spaced apart along the length of said tubular reaction zone and each of said injectors being adapted to introduce a controlled amount of a second fluid reactant into said tubular reaction zone, and at least one of said injectors having a pressure drop control means in said conduit proximate to said injector.
A continuous flow chemical reaction apparatus comprising a fluidized bed reaction zone having a height and having a first fluid feed inlet at a lower end and a product outlet at an upper end, said fluidized bed reaction zone having a multiplicity of injectors in fluid communication with an interior conduit extending vertically within said fluidized bed reaction zone and located within the fluidized bed reaction zone and at least two different heights thereof, each of said injectors capable of introducing a controlled amount of a second fluid reactant into said fluidized bed reaction zone, and at least one of said injectors having a pressure drop control means in said conduit proximate to said injector.
A continuous flow chemical reaction apparatus comprising a plurality of fluidized bed reaction zones within a heat transfer vessel having at least one heat transfer zone, each of said heat transfer zones having a heat transfer fluid inlet and a heat transfer fluid outlet;
A continuous flow chemical reaction apparatus comprising a fluidized bed reaction zone having a height, a first fluid feed inlet at a lower end, a product outlet at an upper end and a multiplicity of conduits along the height of said fluidized bed reaction zone, each of said conduits being perpendicular to fluid flow within the fluidized bed reaction zone and each being adapted to introduce a controlled amount of a second fluid reactant feed into said fluidized bed reaction zone.
