DESCRIPTION OF THE DRAWINGS

[0050] A number of embodiments of the invention will be explained in more detail in the following with reference to the drawings.

[0051] In FIG. 1 an outlet collector 01 for a reactor (not shown) according to the invention is shown. The outlet collector is mounted in the bottom of the reactor where it functions as a gas and/or liquid collector. From the outlet collector, the fluids are conveyed to further processing via an outlet pipe (not shown). The outlet collector in the present embodiment has a cylindrical shape. In a first end of the outlet collector, an aperture 02 is adapted to receive an inspection port. The inner side of the aperture has a compression ring 10 with a an inner diameter adapted to provide a loose fit with the inspection port when the reactor is not in operation and a tight fit when the reactor under operation is subject to operation pressure and temperature. The operation pressure may be around 20 bars, but typically around 7 bar.

[0052] The inspection port 03 which is adapted to be mounted in the outlet collector is shown on FIG. 2. It comprises a cylindrical body 04 which provides structural strength to the inspection port and has an outer diameter which is modified to fit inside the aperture of the outlet collector as described above. A disc shaped cover 05 provides closure of the aperture of the outlet collector when the inspection port is mounted. The disc shaped cover has a thickness and strength adapted to withstand operation pressures and temperatures. To provide additional strength and optionally to save weight, the inspection port of this embodiment is further provided with strengthening structures 06 which are mounted below the disc shaped cover, contacting and supporting it. As shown on FIG. 2, the strengthening structures may be steel bars mounted in a ray pattern, welded together, to the cylindrical body and to the disc shaped cover. On the upper side of the disc shaped cover, opposite the strengthening structures, a locking bar 07 is mounted. It is mounted aligned with the diameter of the disc shaped cover, extending beyond the rim of the disc shaped cover, enough to provide for fixing points 08 adapted to be fixed to counterpart fixing points on the outlet collector. The fixing points of the present embodiment are two apertures, one in each end of the locking bar. As seen on FIG. 2, the locking bar has in its middle section a cut big enough to the passing of one or two hands, for a person's handling of the inspection port. In this way the locking bar serves also as a handle. In the lower part of FIG. 2, a detail picture shows the gap between the cylindrical body of the inspection port and the compression ring of the outlet collector. This gap is between 1 and 2.5 mm when the reactor, outlet collector and inspection port is subject to ambient temperature and pressure, but narrows toward 0 when the reactor, outlet collector and inspection port is subject to operation pressure and temperature.

[0053] FIG. 3 shows the inspection port mounted in the outlet collector, the upper view shows the outlet collector in a cut view to visualize the inner part of the outlet collector with the inspection port mounted. As seen in both the upper and the lower view, this embodiment uses simple bolts as fixing means 09, just two bolts are sufficient to secure the inspection port in its mounted position. Thus the present invention ensures a quick and easy mounting and de-mounting of the inspection port and therefore a quick and easy maintenance and inspection of the outlet collector and the connected outlet pipe.
