The present invention is directed to the prevention of an exothermic reaction in the gas purifier of an ultra-high purity gas system.

System for preventing contaminants from reaching a gas purifier

A system for delivering vapor phase fluid at an elevated pressure from a transport vessel containing liquefied or two-phase fluid is provided. The system includes: (a) a transport vessel positioned in a substantially horizontal position; (b) one or more energy delivery elements disposed on the lower portion of the transport vessel wherein the energy delivery devices include a heating means and a first insulation means, wherein the energy delivery devices are configured to the contour of the transport vessel; (c) one or more substantially rigid support devices disposed on the outer periphery of the energy delivery devices, wherein the support devices hold the energy delivery devices in thermal contact with a lower portion of the transport vessel; and (d) one or more attaching devices secure the rigid support devices onto the transport vessel and hold the energy delivery devices between the substantially rigid support device and a wall of the transport vessel.

Energy delivery system for a gas transport vessel containing low vapor pressure gas

A novel fail-safe temperature monitoring system that can distinguish excessive chemical adsorbent temperature from temperature sensing component failure is provided. This system prevents the gas purifier from shutting down as a result of temperature sensing component failure, and thereby prevents a false shutdown of a high-purity gas production plant.

System for preventing unnecessary shutdown of a high-purity gas production plant

Systems, apparatuses and methods for vapor phase fluid delivery to a desired end use are provided, wherein the conditions of the system are monitored to determine when the water concentration or supply vessel surface temperature exceeds a specified value or when the low vapor pressure fluid pressure falls below a specified value for the purpose of removing a first supply vessel from service by discontinuing vapor flow from the first supply vessel and initiating vapor flow from a second supply vessel.

Low vapor pressure high purity gas delivery system

An autothermal reactor and method for producing synthesis gas in which a heated oxygen containing stream is expanded into a mixing chamber to entrain a hydrocarbon containing stream to form a reactant stream without reaction of the oxygen and hydrocarbon contents of the streams. The reactant stream is reacted in a series of sequential catalytic reaction zones to react the hydrocarbon and oxygen contained in the reactant stream to form the synthesis gas. The sequential catalytic reaction zones are configured such that an initial partial oxidation reaction occurs that is followed by endothermic reforming reactions having ever decreasing temperatures. The sequential catalytic reaction zones in which the endothermic reforming reactions occur contain a precious metal catalyst supported on ceramic supports that have successively greater surface areas to compensate for the temperature decrease while remaining stable and without a transform in state.

Autothermal reactor and method for production of synthesis gas

A system for removing and purifying a carbon dioxide-containing stream from a batch process tool is provided. A multi-phase contaminated stream containing at least carbon dioxide and one or more co-solvent is removed from a process tool and conveyed to at least one intermediate pressure separator. The contaminant-containing stream is separated into an intermediate pressure carbon dioxide-enriched vapor stream and an intermediate pressure solvent and contaminant-enriched stream in the intermediate pressure separator.

Process for carbon dioxide recovery from a process tool

A cryogenic rectification system wherein feed air is provided into the lower portion of a cryogenic rectification column, and liquid having a defined oxygen concentration is withdrawn from a defined intermediate level of the column above the feed air introduction level, vaporized and optionally diluted with nitrogen for recovery as ultra high purity clean dry air.

Cryogenic rectification system for producing ultra high purity clean dry air

A method for providing refrigeration to a cryogenic rectification plant which enables the facile provision of varying amounts of refrigeration to the plant wherein a working fluid is pressurized in a recycle compressor, a first portion is at least partially condensed in a heat exchanger and passed into the plant, a second portion is cooled and then turboexpanded to generate refrigeration, the refrigeration bearing second portion passes refrigeration in the heat exchanger to the first portion to effect the condensation, and the resulting second portion is not passed into the cryogenic rectification plant but rather is returned to the recycle compressor.

Method for providing refrigeration to a cryogenic rectification plant

A system for producing high and ultra high purity nitrogen comprising a first column for the production of nitrogen and a second column having a top condenser wherein boil off from the second column top condenser is turboexpanded to generate refrigeration for the system.

Cryogenic rectification system for producing high purity nitrogen

A system for producing high purity nitrogen comprising a higher pressure first column having a top condenser and a lower pressure second column wherein boil off from the first column top condenser is turboexpanded to generate refrigeration for the system.

Cryogenic rectification system for producing high purity nitrogen using high pressure turboexpansion

A cryogenic rectification system comprising three columns wherein high purity oxygen is produced in the third column which is fed from at least one of the first and second columns, which do not share a common condenser/reboiler, and reboiled using feed air or first column top vapor.

Cryogenic rectification system for producing high purity oxygen

A process and system for producing a high purity argon product with high argon recovery from an air feed stream utilizing a low ratio argon distillation column, a high ratio argon distillation column and a vacuum pressure swing adsorption. unit in combination with a cryogenic air separation plant. The process and system avoids the necessity for an ultrastaged upper column in the cryogenic air separator plant.
