Abstract
Method of loading a tubular reactor with a catalyst tube assembly, method of unloading a catalyst tube assembly from a tubular reactor, and catalyst tube assembly for a tubular reactor, such as a steam reformer, comprising an outer reactor tube having an inlet end and an outlet end opposite the inlet end, and including an inwardly protruding element; a centering assembly including an inner tube having an inlet end and an outlet end; a tubular boundary having a closed end and an open end.
Claims20
Method of loading a tubular reactor with a catalyst tube assembly comprising:
- providing a tubular reactor, including an outer reactor tube having an inlet end and an outlet end opposite the inlet end, and including an inwardly protruding element;
- providing a tubular boundary having a closed end and an open end;
- providing a centering assembly including an inner tube having an inlet end and an outlet end, wherein the outlet end of the inner tube includes at least one sealing member;
- providing annular catalyst structures;
- mounting said annular catalyst structures around said tubular boundary;
- inserting said centering assembly substantially coaxially into the outer reactor tube until the at least one sealing member engages the inwardly protruding element, wherein the centering assembly is inserted into the outer reactor tube before the tubular boundary is mounted over the centering assembly;
- and
- mounting said tubular boundary substantially coaxially over said centering assembly.
Catalyst tube assembly for loading a tubular reactor, comprising:
- an outer reactor tube having an inlet end and an outlet end opposite the inlet end, and including an inwardly protruding element, the catalyst tube assembly comprising:
- a centering assembly including an inner tube having an inlet end and an outlet end;
- a tubular boundary having a closed end and an open end, wherein the tubular boundary is mounted over the centering assembly;
- and
- wherein the tubular boundary is configured to extend substantially coaxially within the outer reactor tube and substantially coaxially around the inner tube, such that the catalyst tube assembly includes a first annular channel between the outer reactor tube and the tubular boundary that is arranged for containing an annular catalyst structure, and a second annular channel between the tubular boundary and the inner tube, wherein the second annular channel is in fluid connection with the first annular channel near the open end of the tubular boundary, and in fluid connection with the inner tube at the closed end of the tubular boundary wherein the outlet end of the inner tube includes at least one sealing member configured to be in sealing engagement with the inwardly protruding element of the outer reactor tube.
Method of loading a tubular reactor with a catalyst tube assembly comprising:
- providing a tubular reactor, including an outer reactor tube having an inlet end and an outlet end opposite the inlet end, and including an inwardly protruding element;
- providing a tubular boundary having a closed end and an open end;
- providing a centering assembly including an inner tube having an inlet end and an outlet end, wherein the outlet end of the inner tube includes at least one sealing member;
- providing annular catalyst structures;
- mounting said annular catalyst structures around said tubular boundary;
- inserting said centering assembly substantially coaxially into the outer reactor tube until the at least one sealing member engages the inwardly protruding element;
- and
- mounting said tubular boundary substantially coaxially over said centering assembly, wherein the annular catalyst structures are mounted around the tubular boundary before mounting said tubular boundary over the centering assembly.
