Abstract

A reactor comprising an outlet collector with an inspection port for easy maintenance and service.

First claim

The invention claimed is:

1. An outlet collector for collecting fluid from chemical reactions in a catalytic reactor and conveying the fluid to further processing, wherein said outlet collector comprises an aperture, and an inspection port received in the aperture, for maintenance and cleaning of the outlet collector, wherein said inspection port comprises:
a cylindrical body;
a disc shaped cover;
a plurality of strengthening beams disposed below the cover in a ray pattern, a line pattern or a square pattern, and;
a locking bar for fixing the inspection port to the outlet collector, the locking bar being disposed on the upper side of the disc shaped cover and being aligned with, and extending across, a diameter of a rim of the disc shaped cover, wherein the locking bar also functions as a handle for mounting and de-mounting of the inspection port, the locking bar including portions extending radially outwardly beyond the rim of the disc shaped cover on opposite sides, the radially outwardly extending portions of the locking bar each including a fixing point adapted to be fixed to a corresponding fixing point on the outlet collector.

2. The outlet collector according to claim 1 , wherein the weight of said inspection port is small enough to enable manual mounting and de-mounting of the inspection port in the outlet collector.

3. The outlet collector according to claim 1 , wherein the weight of said inspection port is in the range of 2-80 kg.

4. The outlet collector according to claim 1 , wherein said inspection port is large enough to enable passing and operation of inspection and cleaning tools.

5. The outlet collector according to claim 1 , wherein said inspection port is large enough to enable the passage of a person.

6. The outlet collector according to claim 1 , wherein said inspection port is cylindrical and has a diameter in the range of 100-1200 mm.

7. The outlet collector according to claim 1 , wherein said inspection port is strong enough to withhold a pressure difference between two sides of the port in the range of 0-50 bars.

8. The outlet collector according to claim 1 , wherein said inspection port is fixed to the outlet collector at said fixing points by fixing means.

9. The outlet collector according to claim 8 , wherein the fixing means is a quick release element.

10. The outlet collector according to claim 8 , wherein the fixing means is a screw and nut element, a screw and wing nut element, a knee joint element or a wedge element or any of the mentioned elements in combination with a keyhole and bolt element.

11. The outlet collector according to claim 1 , wherein the outlet collector comprises compression ring surrounding the aperture, said compression ring is adapted to contact the inspection port when the inspection port is mounted in the outlet collector, the compression ring is constructed to provide a tight fit with the inspection port when the catalytic reactor is in operation and to provide a loose fit when the catalytic reactor is not in operation.

12. The outlet collector according to claim 11 , wherein a gap between the compression ring and the inspection port is in the range of 0.5-5 mm when the reactor is not in operation.
