Abstract

Claims (35)

1 . A reactor comprising:

a shell defining an internal space configured to receive a catalyst;

a domed head portion that includes a startup nozzle including a flange for detachable connection to a reducing flange, the startup nozzle including a manhole access opening through which a maintenance worker can enter the shell of the reactor;

an inlet nozzle; and

a tube bundle comprising a plurality of tubes arranged in concentric bands about a longitudinal axis of the reactor;

and wherein:

the catalyst received within the shell is a solid catalyst, wherein the domed head portion is integral with the shell, without any connecting flanges therebetween;

the reactor further comprises an outlet nozzle, the outlet nozzle being located proximate a bottom portion of the shell;

the reactor further comprises a catalyst support plate, wherein the outlet nozzle is arranged below the catalyst support plate;

the reactor further comprises a plurality of tube support plates, wherein each tube support plate comprises a plurality of circumferential bands, wherein each circumferential band comprises at least one bracket configured to extend about a tube of the tube bundle;

wherein each tube support plate defines a plurality of radial struts, each radial strut being connected between the circumferential bands of the tube support plate;

wherein each radial strut is removably secured to at least one of the circumferential bands of each tube support plate; and

further comprising a gas inlet plate, wherein the gas inlet plate is arranged proximate the inlet nozzle, with the inlet nozzle arranged below the gas inlet plate.

2 . The reactor of claim 1 , wherein the domed head portion includes at least one thermocouple port, wherein the at least one thermocouple port is at a tilted angle relative to a vertical longitudinal axis of the reactor.

3 . The reactor of claim 2 , wherein the domed head portion includes two thermocouple ports, each at a tilted angle relative to the vertical longitudinal axis of the reactor.

4 . The reactor of claim 3 , wherein the thermocouple ports are each tilted away from the startup nozzle at an angle of from about 5° to about 30° relative to the vertical longitudinal axis of the reactor.

5 . The reactor of claim 2 , wherein a circumferential band of the plurality of tube support plates further comprises brackets corresponding to at least one thermocouple insertion tube, wherein the at least one thermocouple insertion tube is configured to receive a temperature measurement device inserted into the reactor through the at least one thermocouple port, the temperature measurement device being configured to obtain a temperature at a plurality of longitudinal locations within the reactor.

6 . The reactor of claim 1 , wherein the catalyst is a solid catalyst that comprises balls of a first diameter and balls of a second diameter, wherein the catalyst balls of the first diameter and the catalyst balls of the second diameter are arranged in discrete, respective layers proximate the catalyst support plate.

7 . The reactor of claim 1 , wherein the catalyst support plate defines one or more apertures, wherein the one or more apertures comprise a plurality of apertures of a first size and a plurality of apertures of a second size, the apertures extending through at least part of a thickness of the catalyst support plate.

8 . The reactor of claim 7 , wherein the first size corresponds to a circumference of at least one tube of the tube bundle, and the second size is smaller than the first size, wherein the apertures of the first size are defined through the catalyst support plate according to an arrangement of the plurality of tubes of the tube bundle.

9 . The reactor of claim 8 , wherein the gas inlet plate comprises a plurality of apertures defined through a thickness of the gas inlet plate, wherein the plurality of apertures are circular apertures defined through the gas inlet plate according to the arrangement of the plurality of tubes of the tube bundle, wherein the gas inlet plate further comprises a second plurality of apertures defined through the thickness of the gas inlet plate, the second plurality of apertures comprising a different size and/or shape than the plurality of circular apertures.

10 . A reactor comprising:

a shell defining an internal space configured to receive a catalyst;

at least one inlet nozzle; and

a tube bundle comprising a plurality of tubes arranged in concentric bands about a longitudinal axis of the reactor;

wherein the reactor further comprises a catalyst support plate including a plurality of apertures formed therethrough through which the plurality of tubes of the tube bundle pass, wherein a support ring is attached around each tube passing through a corresponding aperture of the catalyst support plate, and wherein the tubes are not fixed relative to the catalyst support plate, to allow for thermal expansion of the tubes passing through the catalyst support plate.

11 . The reactor of claim 10 , wherein each tube includes an upper support ring and a lower support ring attached to and extending around each of said tubes, the upper support ring being positioned above the catalyst support plate and the lower support ring being positioned below the catalyst support plate, wherein a spacing between the upper support ring and the lower support ring of a given tube is greater than a thickness of the catalyst support plate.

12 . A reactor comprising:

a shell defining an internal space configured to receive a catalyst;

at least one inlet nozzle; and

a tube bundle comprising a plurality of tubes arranged in concentric bands about a longitudinal axis of the reactor;

wherein the reactor further comprises at least one tube support plate, each tube support plate including a plurality of apertures formed therethrough each tube of the plurality of tubes passing through a corresponding aperture of the tube support plate, wherein the reactor further includes at least one sliding strip at a periphery of the at least one tube support plate, wherein at least one of the tube support plates includes at least one slot formed at a periphery of said tube support plate, for receipt of a corresponding sliding strip.

13 . The reactor of claim 12 , wherein each sliding strip includes an opening for receipt of a thickness of a corresponding one of the at least one tube support plate, wherein a height of the opening in the sliding strip is greater than a thickness of the corresponding tube support plate.
