Abstract
A filter for a sorbent regeneration process includes a base, a central rod, support frames, and a filter screen. The central rod is coupled to the base and defines a longitudinal axis of the filter. Each of the support frames are coupled to and protrude radially from the central rod. Each of the support frames are coupled to the base. For each pair of neighboring support frames, the filter includes a triangular support member disposed between the pair of neighboring support frames. Each triangular member is coupled to the central rod and to each of the neighboring support frames. The filter screen surrounds the support frames and is coupled to the support frames and to the base.
Claims19
A filter for a sorbent regeneration process, the filter comprising:
- a base;
- a central rod coupled to the base, the central rod defining a longitudinal axis of the filter;
- a plurality of support frames, each of the support frames coupled to and protruding radially from the central rod, each of the support frames coupled to the base;
- for each pair of neighboring support frames, at least one triangular support member is disposed between the pair of neighboring support frames, the triangular support member coupled to the central rod and to each of the neighboring support frames;
- and
- a filter screen surrounding the plurality of support frames, the filter screen coupled to the plurality of support frames and to the base.
A system for sorbent regeneration, the system comprising:
- a gas dehydrator comprising a sorbent;
- and
- a filter downstream of the gas dehydrator, the filter comprising:
- a base;
- a central rod coupled to the base, the central rod defining a longitudinal axis of the filter;
- a plurality of support frames, each of the support frames coupled to and protruding radially from the central rod, each of the support frames coupled to the base;
- for each pair of neighboring support frames, at least one triangular support member is disposed between the pair of neighboring support frames, the triangular support member coupled to the central rod and to each of the neighboring support frames;
- and
- a filter screen surrounding the plurality of support frames, the filter screen coupled to the plurality of support frames and to the base.
A method comprising:
- flowing a gas stream through a gas dehydrator comprising a sorbent, wherein the gas stream has an operating temperature at which water desorbs from the sorbent, thereby regenerating the sorbent;
- and
- after flowing the gas stream through the gas dehydrator, flowing the gas stream through a filter, the filter comprising:
- a base;
- a central rod coupled to the base, the central rod defining a longitudinal axis of the filter;
- a plurality of support frames, each of the support frames coupled to and protruding radially from the central rod, each of the support frames coupled to the base;
- for each pair of neighboring support frames, at least one triangular support member is disposed between the pair of neighboring support frames, the triangular support member coupled to the central rod and to each of the neighboring support frames;
- and
- a filter screen surrounding the plurality of support frames, the filter screen coupled to the plurality of support frames and to the base, wherein flowing the gas stream through the filter comprises flowing the gas stream through the filter screen radially inward toward the central rod.
