Abstract
A system for chemical vapor infiltration and densification may comprise a reaction chamber and a plurality of conduits fluidly coupled to an exhaust outlet of the reaction chamber. A first set of conduits of the plurality of conduits may define a first flow path and a second set of conduits of the plurality of conduits may define a second flow path. The second flow path may be fluidly coupled to an inlet of the reaction chamber. A hydrogen extraction component may be in fluid communication with a least one of the first set of conduits or the second set of conduits.
Claims19
A system for chemical vapor infiltration and densification, the system comprising:
- a reaction chamber;
- a plurality of conduits fluidly coupled to an exhaust outlet of the reaction chamber, wherein a first set of conduits of the plurality of conduits define a first flow path and a second set of conduits of the plurality of conduits define a second flow path, wherein the second flow path is fluidly coupled to an inlet of the reaction chamber;
- a roughing pump fluidly coupled to the first set of conduits, wherein an outlet of the roughing pump is fluidly coupled to the inlet of the reaction chamber;
- a first valve in operable communication with the first set of conduits, wherein the roughing pump is downstream of the first valve;
- a second valve in operable communication with the second set of conduits;
- a first pump downstream of the second valve and configured to drive fluid through the second set of conduits;
- and
- a first hydrogen extraction component in fluid communication with the second set of conduits and the first set of conduits, wherein the first hydrogen extraction component comprises a cryogenic-cooler configured to condense hydrocarbon molecules comprised of five or less carbon atoms, and wherein a first outlet of the first hydrogen extraction component is fluidly coupled to the first set of conduits and a second outlet of the first hydrogen extraction component is fluidly coupled to the second set of conduits;
- and
- at least one of a trap configured to condense hydrocarbon molecules having six or more carbon atoms or a plasma conduit configured to breakdown hydrocarbon gases comprised of six or more carbon atoms located upstream of the first hydrogen extraction component.
