Abstract

The present invention discloses a flow reactor composed of plurality of modular/fluidic components that helps retain agility and re-configurability of the continuous chemical processes with improved processing ability. More specifically, disclosed herein is a continuous flow reactor composed of varied permutations and combinations of a plurality of modular/fluidic components for chemical processing. The components are connected to each other using connectors that facilitate the connection of either with two or more, similar or different components.

First claim

We claim:

1. A flow reactor assembly that helps retain agility and re-configurability of a continuous chemical process with improved processing ability comprising a tubular reactor consisting of metallic or non-metallic fluidic/modular components that are arranged together in varied numbers and arrangement having single or multi feed inlets, in periodic or aperiodic sequences; using connectors that facilitate connection with two or more similar or different components comprising;
a helical coil element with similar or variable radii of curvature, pitch and diameter with single point or multi point feed arrangement,
a flow disrupter comprising a cross-sectional internal flow area, wherein the flow disrupter comprises a cavity with a shape selected from the group consisting of cylindrical polygonal and polyhedral with suitable input and output connectable ports with the helical coil elements; and/or
a vortex diode comprising metallic or non-metallic, single or multiple tangential ports of the diode as inlet and an axial port as outlet and having connectable ports with the helical coil elements;
wherein said metallic or non-metallic fluidic/modular components optionally comprise an internal flow divider configured to achieve a desired residence time, to reduce axial dispersion, and to enhance intensity of local mixing and chemical reaction in the tubular reactor; and
wherein the internal flow area of the flow disrupter comprises respective inlet and outlet ports, the cross-sectional internal flow area of the flow disrupter comprises a longitudinal variation, and the flow disrupter comprises a plurality of metallic and non-metallic components in different possible sequences.

2. The flow reactor according to claim 1 , wherein each of the metallic or non-metallic fluidic/modular components further comprise multiple metallic and non-metallic fluidic elements having respective inlet and outlet ports.

3. The flow reactor according to claim 1 , wherein the helical coil element is in combination with other coil elements of different coil diameter, wherein a smaller coil is held inside or outside the volume occupied by a larger one with identical or non-identical axis of symmetry for the individual coils.

4. The flow reactor according to claim 1 , wherein a periodic and an aperiodic sequence of helical coil elements of identical curvature and similar tube diameters are connected with non-cylindrical segments comprising single point as well as multi point feeding systems.

5. The flow reactor according to claim 1 , wherein a periodic and an aperiodic sequence of helical coil elements of similar radii of curvature with endpoints are attached to another coil having a different radius of curvature, wherein said different radius of curvature has a similar or a different tube diameter and pitch.

6. The flow reactor according to claim 1 , wherein a periodic and aperiodic sequence of helical coil elements having similar radius of curvature is connected with vortex diodes in a single point and multi point feed arrangement.

7. The flow reactor according to claim 1 , wherein a periodic and aperiodic sequence of helical coil elements having similar radius of curvature is connected with the vortex diode and the flow disrupter in a single point and multi point feed arrangement.

8. The flow reactor according to claim 1 , wherein the individual metallic or non-metallic fluidic/modular components can have identical or different axis of symmetry.

9. The flow reactor assembly of claim 1 , wherein the flow disrupter comprises a triangular, square or pentagonal cross-sectional internal flow area shape.

10. A flow reactor assembly that helps retain agility and re-configurability of a continuous chemical process with improved processing ability comprising a tubular reactor consisting of metallic or non-metallic fluidic/modular components that are arranged together in varied numbers and arrangement having single or multi feed inlets, in periodic or aperiodic sequences; using connectors that facilitate connection with two or more similar or different components, said components comprising:
a helical coil element with similar or variable radii of curvature, pitch and diameter with single point or multi point feed arrangement,
