Abstract

A gasket locating arrangement for a flow module, preferably plate reactor, includes a gasket, one or more locating devices, a channel in a channel plate, and a barrier plate. The gasket consists of a sheet of soft gasket material. The sheet has a cut through pattern corresponding to the channel in the channel plate. The locating devices are in the gasket, in the channel plate, in the barrier plate or combinations thereof. The locating devices are headed pins, fitting pins, protruded pins, integrated pins, dowel pins, grooves, holes, under cut recesses, thickened parts in the gasket material, and/or gasket deformation zones.

First claim

The invention claimed is:

1. A gasket locating arrangement for a flow module, preferably plate reactor, comprising:
a gasket,
locating means,
a channel in a channel plate,
a barrier plate,
wherein the gasket consists of a sheet of soft gasket material, and said sheet has a cut through pattern corresponding to the channel in the channel plate,
the locating means are in the gasket, in the channel plate, in the barrier plate or combinations thereof, which locating means are selected from the group consisting of headed pins, fitting pins, protruded pins, integrated pins, dowel pins, grooves, holes, under cut recesses, thickened parts in the gasket material, gasket deformation zones, wherein the locating means in the gasket, in the channel plate, or in the barrier plate are fitted into or to corresponding locating means in the gasket, in the channel plate, in the barrier plate or in combinations thereof leaving a flat surface together with the gasket between the channel plate and the barrier plate when the gasket locating arrangement is assembled for sealing the channel of the channel plate, and that the cut through pattern in the gasket makes it possible for the flow of media or the flow of fluids in the channel of the channel plate to touch the barrier plate and to have no contacts with the gasket's planar faces and little or minimized contact with any of the gaskets edges.

2. The gasket locating arrangement according to claim 1 , comprising the locating means for locating the gasket between the barrier plate and the channel plate are holes or pins or both holes and pins, the means locate the gasket between the barrier plate and the channel plate, and wherein heads of pins are allowed to disappear in counter sunk area of holes leaving a flat surface together with the gasket when the gasket locating arrangement is assembled.

3. The gasket locating arrangements according to claim 1 , wherein the pins are located into holes in the barrier plate or into holes in the channel plate, and the pins are located through holes in the gasket.

4. The gasket locating arrangements according to claim 1 , wherein the pins are integrated in the channel plate or integrated in the barrier plate, or the pins are integrated in both the channel plate and the barrier plate.

5. The gasket locating arrangements according to claim 1 , wherein thickened parts in the gasket material, holes in the gasket material, or deformation zones in the gasket material locate the gasket to corresponding holes, grooves or under cut recesses in the barrier plate, in the channel plate or in both channel plate and the barrier plate.

6. The gasket locating arrangements according to claim 1 , wherein the holes have countersunk areas, the holes are all-through holes, or the holes are all-through holes having countersunk areas.

7. The gasket locating arrangements according to claim 1 , wherein the soft gasket material is selected from the group of materials consisting of multi layer expanded polytetrafluoroethylene (ePTFE), polytetrafluoroethylene (PTFE), perfluorelastomers, fluorelastomers, polyetheretherketone (PEEK), and polypropene (PP).

8. The gasket locating arrangements according to claim 1 , wherein the soft gasket material is expanded polytetrafluoroethylene (ePTFE) having layers of a stochastic fibrous structure and large amount of void space the material undergoes a nonrecoverable deformation under assembly compression.

9. The gasket locating arrangements according to claim 1 , wherein the pins are made of a material selected from the group consisting of polytetrafluoroethylene (PTFE), perfluorelastomers, fluorelastomers, polyetheretherketone (PEEK), and polypropene (PP).

10. A method of using gasket locating arrangements, the method comprising:
providing a gasket locating arrangement comprising:
a gasket,
locating means,
a channel in a channel plate,
a barrier plate,
wherein the gasket consists of a sheet of soft gasket material, and said sheet has a cut through pattern corresponding to the channel in the channel plate,
the locating means are in the gasket, in the channel plate, in the barrier plate or combinations thereof, which locating means are selected from the group consisting of headed pins, fitting pins, protruded pins, integrated pins, dowel pins, grooves, holes, under cut recesses, thickened parts in the gasket material, gasket deformation zones, wherein the locating means in the gasket, in the channel plate, or in the barrier plate are fitted into or to corresponding locating means in the gasket, in the channel plate, in the barrier plate or in combinations thereof leaving a flat surface together with the gasket between the channel plate and the barrier plate when the gasket locating arrangement is assembled for sealing the channel of the channel plate, and that the cut through pattern in the gasket makes it possible for the flow of media or the flow of fluids in the channel of the channel plate to touch the barrier plate and to have no contacts with the gasket's planar faces and little or minimized contact with any of the gaskets edges; and
sealing a channel in a plate reactor or plate flow module with the gasket locating arrangement.

11. A flow module comprising:
at least one gasket locating arrangement comprising:
a gasket,
locating means,
a channel in a channel plate,
a barrier plate,
wherein the gasket consists of a sheet of soft gasket material, and said sheet has a cut through pattern corresponding to the channel in the channel plate,
the locating means are in the gasket, in the channel plate, in the barrier plate or combinations thereof, which locating means are selected from the group consisting of headed pins, fitting pins, protruded pins, integrated pins, dowel pins, grooves, holes, under cut recesses, thickened parts in the gasket material, gasket deformation zones, wherein the locating means in the gasket, in the channel plate, or in the barrier plate are fitted into or to corresponding locating means in the gasket, in the channel plate, in the barrier plate or in combinations thereof leaving a flat surface together with the gasket between the channel plate and the barrier plate when the gasket locating arrangement is assembled for sealing the channel of the channel plate, and that the cut through pattern in the gasket makes it possible for the flow of media or the flow of fluids in the channel of the channel plate to touch the barrier plate and to have no contacts with the gasket's planar faces and little or minimized contact with any of the gaskets edges;

one or more heat transfer devices for heat transfer to and from the channel, and wherein each channel plate has at least one inlet to the channel, and one outlet from the channel.

12. A flow module according to claim 11 , wherein the channel plate has one or more port holes, which port holes makes it possible to access the channel.

13. A flow module according to claim 11 , wherein the one or more heat transfer devices comprises a utility plate and a barrier plate, between the utility plate and the barrier plate is a turbulator insert inserted for enhancing the heat transfer to and from the channel of the channel plates.

14. A flow module of claim 11 , wherein the flow module comprises a plate reactor.
