Multiple element support beam
The present application relates to a vessel support beam comprising two or more beam elements wherein each beam element comprises a first and second opposing long side connected by a top side, a lower side and two opposing end sides, said beam elements are arranged parallelly with at least one long side of one beam element facing a long side of another beam element, thereby forming a reactor support beam having a first and second opposing long side surface, a top surface and a lower surface.
1. A support beam configured to be installed inside a vessel comprising two or more longitudinal beam elements wherein each beam element comprises a first and second opposing long side connected by a top side, a lower side and two opposing end sides, said lower side having a width greater in dimension than said top side to form a bottom shoulder, said beam elements are arranged in parallel with at least one long side of one beam element facing a long side of another beam element, thereby forming the vessel support beam having a first and second opposing long side surface, a top surface and a lower surface, wherein each of said beam elements includes holes extending through the opposing long sides, such that holes of one beam element align with corresponding holes of an adjacent beam element, said support beam further comprising connecting means for locking the beam elements together, and wherein said bottom shoulder is adapted to support a number of catalyst grids, the beam further comprising protruding flaps configured to follow a curvature of an inner vessel wall.
2. The support beam according to claim 1 , wherein said vessel is one of a reactor, distillation and an absorption tower, and wherein the reactor is one of a hydroprocessing reactor, a methanol reactor and an ammonia reactor.
3. The support beam according to claim 1 , wherein at least two beam elements are arranged parallelly with one long side of one beam element facing a long side of the other beam element thereby defining a contact plane P and where the surface normal N of the contact plane P is at least substantially perpendicular to the gravity g.
4. The support beam according to claim 1 , wherein one or more of the beam elements further comprises means for fastening and/or supporting the support beam and/or beam element in a vessel.
5. The support beam according to claim 1 , wherein one or more of the beam elements comprises one or more sections with reduced material thickness or density.
6. The support beam according to claim 1 , wherein the top sides of the beam elements together form a reactor support beam top surface.
7. The support beam according to claim 6 , comprising cover means for covering at least part of the reactor support beam top surface.
8. The support beam according to claim 1 , wherein the connecting means is at least one of a U-clamp and a bolt, wherein the bolt extends through the holes.
9. The support beam according to claim 1 , wherein the connecting means is a U-clamp arranged to support a support beam in a vessel.
10. The support beam according to claim 1 , wherein the connecting means for locking the beam elements together are arranged in at least one of a center section and end zones of the long sides of the beam elements.
11. The support beam according to claim 1 , wherein the effective length of some or each of the connecting means are longer than the distance between the first and second long side surface in an initial configuration of the reactor support beam.
12. The support beam according to claim 1 , wherein the support beam is made of one or more metals.
13. The support beam according to claim 1 , wherein the one or more beam elements has one or more truncated zones.
14. A vessel comprising at least one support beam according to claim 1 .
15. The vessel according to claim 14 wherein said vessel is one of a reactor, distillation and absorption tower, and the reactor is one of a hydroprocessing reactor, a methanol reactor and an ammonia reactor.
