Description
A Tube Module
The present invention relates generally to a tube module or a tube module
system, and uses of the tube module or the tube module system. The invention
particularly relates to a l tube r or a coaxial tube reactor .
Background
Tubular reactors have been in use for several years, examples of such reactors
are disclosed by US3052524 and 68932048, which describe a concentric tubular
reactor consisting of three tubes with the heat transfer fluid flowing in the most
inner and most outer tubes and with the reactant fluid g in the middle tube.
Another example is disclosed by W02009150677 which shows a three concentric
tube system for catalytic reactions.
Traditional concentric tubular reactors have a constant profile, i.e. the flow path is
straight, in both the process and utility sides. This means that the flow within the
r reactor, on both sides, is often laminar, particular at lower flow rates,
which are commonly employed on the process side when reactions take many
seconds up to several minutes to complete.
Operating in the laminar flow regime provides:
0 Poor Mixing
- Poor Heat Transfer (unless the ce between the walls is very small)
0 Poor Plug Flow
This can result in reduced t yield or selectivity of the d product, and
thus the end mixture will contain undesired ducts which need to be
separated from the desired product.
The Invention
Accordingly, the present invention finds a solution to the above mentioned
problems by providing a tubular flow module or coaxial tube flow module, in
particular a coaxial tube reactor or a coaxial tube heat ger, which tubular
flow module comprises at least two spiral shaped concentric tubes. Thus the
present ion relates to a tubular flow module, which flow module comprises
at least two concentric tubes with continuous annular spiral features. The
concentric tubes may be arranged to each other that one tube, i.e. the second
tube, may be coaxially arranged inside the other tube, i.e. the first tube, and each
tube has a m diameter and a minimum diameter. The maximum diameter
of the second tube may be larger than the m diameter of the first tube and
thus forming a space between the first tube and the second tube. The space is
defining a flow path for fluids between first tube and the second tube and the flow
path is defined as a combination of an annular spiral flow path and an axially
1O winding flow path.
The first and second concentric tubes having the continuous annular spiral
features, i.e. the outer and inner spiral tubes, may be lly arranged that a
space may be formed n them. Such geometry forces the fluid flow to
continuously change direction and hence induces vortices which improves
mixing, heat transfer and plug flow. The flow path may thus be defining an
annular path for fluids limited by the surfaces and may be shaped as spiral
waves. Thus the outer and inner tubes having the spiral features may be
d like a screw and nut, where the spiral features acts like the threads. The
inner spiral tube may be screwed into the outer spiral tube when the tubes are
assembled to each other. In the clearance between the spiral features the desired
annular winding flow path may be formed.
The tubular flow module may also comprise a tube coaxially arranged outside the
first tube. The minimum diameter of the outside tube may be larger or smaller
than the maximum er of the first tube, and the formed annular space may
be defined as the space n the outer tube and the first tube and that the
annular space may be for heat transfer fluids or other fluids.
The tubular flow module may also comprise a tube coaxially arranged inside the
second tube. The maximum diameter of the inside tube may be smaller or larger
than the m diameter of the second tube, and the formed annular space
may be defined as the space between the inside tube and the second tube and
that the annular space may be for heat transfer fluids or other fluids.
The inside tube and the outside tube, respectively, may ly be selected from
the group ting of cylindrical tubes, corrugated tubes, ribbed tubes, spiral
shaped tubes, or tubes with spiral fins.
The tubular flow module may comprise more than two concentric tubes with spiral
features coaxially ed to each other forming more than one annular flow
path for fluids.
The flow module may thus have one or more flow paths and one or more annular
flow spaces. The annular flow paths may be for process flows, but it is also
possible that the annular flow paths may be for heat transfer fluids. The annular
flow spaces may be for heat transfer fluids or for process fluids.
The tubular flow module may comprise more than two spiral shaped tric
tubes coaxially arranged to each other forming more than one annular flow path.
Also the annular flow’spaces, i.e. the flow spaces for heat transfer fluids or for
process fluids may be arranged lly within the flow module. Each annular
flow path and each annular space may have at least one inlet and at least one
outlet. Several concentric annular flow paths and annular flow spaces may be
within the same flow module, and the tubes may be of any kind of suitable shape
and could be selected from the group consisting of rical tubes, corrugated
tubes, ribbed tubes, spiral shaped tubes, or tubes with spiral fins.
In the tubular flow module according to the invention the tubes having spiral
features may be selected from the group consisting of spiral shape formed walls,

The annular space between a spiral shaped tric tube and an inside or
outside tube may have one or more spacers arranged within the space to secure
the flow path and to provide a predesigned distance between the spiral shaped
concentric tube and the inner or the outer tube. The flow paths may further be
secured by one or more end connection pieces. The tubes of the invention may
have locating means to be located with the one or more end connection pieces,
and thus position and stabilise the arrangement of tubes. The end connection
pieces may have ports for fluids. The ports may be arranged in tangential
direction to the flow path, in radial direction to the flow path or in udinal
alignment, i.e. axial direction, with the tubes on the end connection pieces.
All parts, i.e. tubes having spiral features, inner tubes, outer tubes, and end
connection pieces may be mounted together by for e a bolt, but other
solutions may be possible such as welding, brazing, hydraulics. One or two nuts
may be the means for closing the module together with the bolt. End caps
arranged within two end connection pieces could be one way of closing the
module either together with the nuts and bolts or without. The end connection
piece er with the end cap could be separate pieces or be integrated into
one piece depending on how the module may be constructed and closed. One or
two springs such as l s, disc springs, packs of disc springs, could be
used tuned to compensate for thermal expansion and/or as a safety to allow the
tubes to open at to high pressures.
The tubular flow module may have one or more access ports or one or more port
holes, or combinations thereof, which access ports or port holes may be providing
access to the annular flow paths or to the annular spaces. The access ports or
the port holes may be inlets for fluids, outlets for fluids or ports for instruments
The access ports or the port holes may be arranged tangential, radial, or axial to
annular flow paths or to the annular space.
The one or more access ports or one or more port holes, or combinations thereof
may be ed with one or more port fittings. The port fittings may have
arrangements for nozzles, for sensor units, for thermo couples, for spring—loaded
sensors or for resistance thermometers.
The nozzles, which may be inserted through the port fittings according to the
invention, may be selected from any suitable nozzles. Examples of nozzles are
injection nozzles, dispersion nozzles, persion s, re—mixing nozzles,
coaxial nozzles, tube nozzles etc.
A coaxial nozzle could be defined as a nozzle with two or more tubes arranged
within each other, that a larger tube having a large radius is surrounding a smaller
tube having a smaller radius. When such a nozzle is used two or more fluids can
be mixed or form dispersions. A re-mixing nozzle could be a tube nozzle having a
hole with a nozzle head and the hole has a smaller radius than the tube. The
nozzle may be a dispersion nozzle which can have one or more holes at the
outlet of the dispersion nozzle and the holes can be arranged in concentric circles
or the holes can be arranged in other suitable patterns.
The material of the tubes of the flow module may be ed from the group
ting of stainless steel, iron—based alloys, -based alloys, titanium,
titanium , tantalum, tantalum alloys, molybdenum—base alloys, zirconium,
zirconium alloys, glass, quartz, graphite, reinforced graphite, Hasteloy, or any
other material resistant to the process media. Other le material for the
tubes are special materials such as plastic material such as PEEK
(polyetherether ketone), PPS (polyphenylensulfid), PTFE (polytetrafluoro—
ethylene), perfuorelatomers, or fluorelastomers, PP (polypropene), etc which the
tubes could be made of. The different tubes could be of the same material but it is
also le that different tubes may be made of ent materials. It could be
possible that at least one of the tubes could be made of a membrane material
and thus the tube module could have membrane capacity. The tubes could be
coated fore instance with catalyst material or any other type of material which has
ties suitable for the purpose of the flow module.
The present invention also relates to a tubular flow module system, which tubular
flow module system may comprise that at least two tubular flow modules may be
connected in series, parallel or combinations thereof to each other. A further
alternative may be that the tubular flow module system may be inside or within a
shell g a shell and tube system.
The r flow module according to the invention may be used as a reactor for
chemical reactions, as a heat exchanger for heat transfer, as a contactor for
separations or for extractions, or ations thereof.

Detailed description of the drawings
Two concentric spiral shaped tubes 1 and 2 are formed in a way which allows
one of them to be engaged in the other. The spirals shape will work as a thread,
where outside diameter of the inner tube 2 is larger than the inside diameter of
WO 68290 2012/071561
the outer tube 1. in the clearance between the two tubes a space, i.e. a flow path
3 is . Flow path 3 forms a spiral shaped path, and also a winding path in
both axial and radial direction of tubes 1 and 2.
The design may suitably be used as a fluid flow path, the fluids may be process
fluids or heat transfer fluids. The mean flow direction is in the axial direction.
There will also be changing velocities in the radial— and tangential directions of
the tube. The size of the velocity components can be tuned by the spirals pitch A
clearance B, and feature height C. The velocity changes induce vortices in all
directions. This is good for mixing, breaking up of boundary layers and creates
improved plug—flow conditions. The ratio of wetted surface to the volume of the
space may be adjusted by the clearance between the spirals. These features
make the design suitable for flow modules, reactors, heat exchangers etc. The
flow of fluid may be of any kind such as liquids, es or gas
Figure 2 shows that outer spiral tube 1 may be enclosed in outer tube 4, g
annular space 5 or path for fluids flow, for e heat transfer , between
outer spiral tube 1 and outer tube 4. Inner spiral tube 2 may enclose inner tube 6
forming annular space 7 for fluids flow, for example heat er fluids, between
inner tube 6 and inner spiral tube 2. Tubes 4 and 6 may be straight concentric,
i.e. cylindrical tubes, as shown in Figure 2. Tubes 4 and 6 may be spiral shaped
or tubes with spiral fins or tubes 4 and 6 may have any other suitable shape, such
as corrugated, ribbed tubes or any other shape that fits inside or outside the
spiral tubes, i.e. tubes 1 and 2, other types shapes of tubes 4 and 6 than the
cylindrical shape are not shown in Figure 2.
Annular spaces 5 and 7 may be equipped with one or more spacers, said spacers
are not shown in Figure 2, between outer cylindrical tube 4 and outer spiral tube
1, and inner cylindrical tube 6 and inner spiral tube 2 respectively. The spacers
could be used for the purpose of reinforcement, for alignment, as mixing
enhancing elements, or as fixing sites.
Spiral tubes 1 and 2 are located to each other in both axial and tangential
direction in each end by an end connection piece 9. Locating means are
integrated in the mating parts. Spiral tubes 1 and 2 and end connection pieces 9
seal against each other by means of a replaceable seal, i.e. O—ring, etc. or a
permanent seal, i.e. weld, braze, etc. End connection pieces 9 has one or more
ports 10 for connecting to a fluid line or an instrument like for exampie a
thermocouple or a pressure transducer.
Outer tube 4 and outer spiral tube 1 are sealed by end connection pieces 11. No
1O tangential on is needed for this case with a rical tube 4. End
connection piece 11 has one or more ports 12 for connecting to a fluid line or an
instrument like for example a thermocouple or a pressure transducer. Ports 12
may be arranged in a tangential direction to spiral shaped tube 1 in the direction
which guides the fluid in the preferred direction.
Inner tube 6 and inner spiral tube 2 are sealed by end connection pieces 13. No
tangential location is needed for this case with cylindrical tube 6. End connection
piece has one or more ports 14 for connecting to a fluid line or an instrument like
for example a couple or a pressure transducer. Ports 14 may be arranged
in a tangential direction to the spiral shaped tube 2 in the direction which guides
the fluid in the preferred direction. All seals are to ambient and not n the
flow paths or annular spaces 3, 5 and 7 to minimize risk of cross contamination.
All parts, i.e. spiral tubes 1 and 2, cylindrical tubes 4 and 6, and end connection
pieces 9, 11 and 13 are held together by a bolt 15, nuts 17, end caps 16 and disc
spring packs 18. Disc springs 18 may be tuned to compensate for thermal
ion effects or/and as a safety e or device to allow the tubes to open
at too high pressures.
Several units forming a flow module system may be connected together. Ports
, 12, and 14 maybe connected in between the units or in manifolds.
Figure 3 is showing a tubular flow module wherein space 7 between spiral tube 2
and cylindrical tube 6 has been equipped with mixing enhancing element 19
arranged on cylindrical tube 6. Mixing enhancing element 19 could be a thread 19
or spiral fins 19 which follow the spiral shape of spiral tube 2. A corresponding
ement could be created in space 5 between cylindrical tube 4 and spiral
tube 1, this is not seen in Figure 3. Ports 10, 12, and 14, are inlets of fluids,
s of fluids or ports for instruments. in Figure 3 ports 10, 12, and 14, are
arranged tial or radial to annular flow path 3 or to annular spaces 5 and 7,
but other atives are possible. One possible arrangement of ports would be
1O to arrange the ports axial to the flow paths or the flow spaces, this is not seen in
Figure 3.
Figure 4 is showing the relationship of pitch A, clearance B and spiral feature
height C of spiral tubes. Pitch A, clearance B and spiral feature height C is also
able for cylindrical tubes which have spiral fins 19 arranged to enhance
mixing within flow spaces 5 and 7 Figure 4 dose not disclose this. Pitch A,
clearance B and spiral feature height C could also promote plug flow type of flow
of fluids in each annular flow path 3 and flow spaces 5 and 7.
