摘要:
An evaporator including a lower drum, an upper drum, and at least one tube extending between the lower drum and the upper drum. The plurality of tubes have fluid passageways therein extending from the lower drum to the upper drum. A duct is provided having a heating gas passageway provided therein. The at least one tube extends through the heating gas passageway. The fluid passageways define an overall flow path from the lower drum to the upper drum extending in a direction substantially counter- current to an overall flow path defined by the heating gas passageway extending from a gas inlet of the heating gas passageway to a gas outlet thereof.
摘要:
A pressure swing adsorption (PSA) including a first PSA module having a first manifold, a second manifold, and a plurality of pressure vessels extending between the first manifold and the second manifold. The unit further includes at least one support member attached to one of the manifolds and configured to provide rigidity thereto. The support member is preferably made of a material different from the manifold to which it is attached. The PSA unit can also include a structure for clamping the plurality of pressure vessels between the first manifold and the second manifold without imposing a bending moment to the vessels.
摘要:
A recycling apparatus for spent protective atmosphere gas contaminated with fouling organic decomposition byproduct materials. The recycling apparatus includes a compressor having an inlet connected to a spent protective atmosphere gas supply line, and a solvent supply configured to supply solvent to a gas passage at or upstream of the compressor. The recycling apparatus also includes a first chamber connected to an outlet of the compressor, where the first chamber is configured to receive compressed gas from the compressor and to collect a mixture including the solvent and any contaminants entrapped or dissolved in the solvent.

A hydrogen plant including a fuel reforming plant (10) configured to receive and process hydrocarbon feedstock (12) and configured to discharge wet reformate (20) including a hydrogen-containing gas stream, and a condenser (30) configured to cool the wet reformate (20). The hydrogen plant also includes a water separator (50) configured to receive the cooled wet reformate (20), remove water (52) from the wet reformate, and discharge dry reformate (60). The hydrogen plant further includes a hydrogen purifier (70) configured to receive the dry reformate (60), process the dry reformate (60), and discharge pure or substantially pure hydrogen (72). A supplemental cooling system (90) is provided in the hydrogen plant to cool the wet reformate (20) in addition to the condenser (30).
摘要:
A pressure swing adsorption (PSA) system including a first group of PSA modules having a plurality of first PSA modules, and a second group of PSA modules having a plurality of second PSA modules. The system includes a feed gas manifold, a product manifold, and a waste manifold connected to the first PSA modules and the second PSA modules. Each first PSA module operates on a first PSA cycle in synchronization with the other first PSA modules, and each second PSA module operates on a second PSA cycle in synchronization with the other second PSA modules. The first PSA cycle is offset from the second PSA cycle. The PSA modules include a plurality of pressurized adsorbent chambers, an inlet manifold, and an outlet manifold. A rigid structure is provided that connects the inlet manifold to the outlet manifold, and structurally joins the inlet and outlet manifolds to the adsorbent chambers.
摘要:
A housing for a heat exchange apparatus including a fluid passageway partially defined by a baffle plate having an extended portion. The heat exchange apparatus further includes an array of fluid conduits extending through the fluid passageway. The housing includes a plurality of housing members each having a wall and at least one flange extending from the wall. The flanges of adjacent housing members are joined at a flange joint, and the flange joint is configured to fixedly receive the extended portion of the baffle plate. The apparatus also includes a plate member is provided within the fluid passageway and intumescent material fills a gap between the baffle plate and the plate member. Additionally, a second baffle plate is provided that defines a portion of a second fluid passageway, where a refractory gasket and a layer of intumescent material are provided between the first and second baffle plates.
摘要:
A method of operating a multistage gas compressor system including providing a plurality of compressor stages connected in series, receiving a gas flow having contaminants within a gas passage, and supplying solvent to the gas passage at or upstream of a compressor in a compressor stage of the plurality of compressor stages to entrap or dissolve the contaminants in the gas flow. The method includes resisting disabling fouling of the compressor in the compressor stage from any contaminants entrapped or dissolved in the solvent, for example, by controlling a discharge temperature of the compressor, and/or using a type of compressor that is not susceptible to being disabled by fouling in at least the first stage. The discharge temperature can be controlled by providing the compressor with a pressure ratio selected to provide a desired discharge temperature.
摘要:
A ductwork system including a duct having a plurality of ducting panels joined together to define a flow passage extending therethrough, and the duct having structure for resisting damage thereto caused by a detonation within the duct. The structure for resisting damage can include an internal bracing within and extending across the flow passage of the duct to tie at least two sides of the duct together. For example, the internal bracing can be a reinforcement panel including a mounting frame with one or more elongated members extending from one side of the frame attached to a ducting panel to another side of the frame attached to an opposite ducting panel. Alternatively or in addition to the above structure, the duct can have structure for resisting damage that includes providing the duct with at least one curved or faceted side along an axial length of the duct.
