Abstract
A tubular flow module includes at least two concentric tubes with spiral features, wherein first tube is coaxially arranged inside a second tube and each tube has a maximum diameter and a minimum diameter, wherein the maximum diameter of first tube is larger than the minimum diameter of second tube, defining a flow path for fluids between first and second tubes. A tubular flow module system and use of the tubular flow module is also disclosed.
Claims18
A tubular flow module comprising:
- at least two concentric tubes with continuous annular spiral features,
- wherein a first of the concentric tubes is coaxially arranged inside a second of the concentric tubes and each of the concentric tubes has a maximum diameter and a minimum diameter,
- wherein a maximum diameter of the first tube is larger than a minimum diameter of the second tube forming a first space between the first tube and the second tube,
- wherein the first space defines a flow path for fluids between the first tube and the second tube,
- a first end connection piece extending between the first tube and the second tube, the first end connection piece forming a first end;
- a second end connection piece extending between the first tube and the second tube, the second end connection piece forming a second end;
- a first inlet port to the first space, the first inlet port formed axially inward from the first end;
- a first outlet port from the first space, the first outlet port formed axially inward from the second end,
- a third tube coaxially arranged outside the second tube,
- wherein a minimum diameter of the third tube is larger than the maximum diameter of the second tube,
- wherein a second space is defined between the third tube and the second tube, the second space being for heat transfer fluids or other fluids, and
- a third end connection piece extending between the third tube and the second tube, the third end connection piece forming a third end.
