A method for removing impurities from a feed air gas stream prior to the stream being fed to a cryogenic distillation unit. The feed air gas stream contacts an ionic liquid which adsorbs the impurities from the air. The method can use one or more beds such as in pressure swing adsorption processes.

Gas prepurification process

An apparatus and method for recovering and recycling a coolant gas from a heat exchanger. The apparatus comprises a coolant gas recovery section, and analysis section, and a coolant gas blending section. The coolant gas recovery section recovers a coolant gas containing contaminants from the heat exchanger. The analysis section monitors a condition of an analysis portion of the recovered coolant gas. The coolant gas blending section operates to produce, based on the condition of the recovered coolant gas monitored by the analysis section, a blend coolant gas comprising a virgin coolant gas and a reclaimed coolant gas that comprises at least a portion of the recovered coolant gas. The blend coolant gas has a predetermined contaminant concentration and is recycled into the heat exchanger. Thus, the coolant gas is recovered from, and recycled to, the heat exchanger at the predetermined contaminant concentration without using a purification device.

Apparatus and method for recovery and recycle of optical fiber coolant gas

A cap assembly for collecting cooling gas from a coolant chamber tube is disclosed. The cap assembly having connecting means and outlet means extending from its side walls being generally shaped and sized for detachable mounting on the body of the cooling gas chamber tube. The cap assembly is also employed in a hot optical fiber process which is being cooled by helium.

Cap assembly and optical fiber cooling process

A process for separating a gas component from a gas mixture is disclosed. A gas mixture is passed through an adsorption zone which contains an adsorbent which will selectively adsorb a gaseous component from the gas mixture. The adsorption zone contains a layer of monolithic adsorbent and a layer of adsorption beads. Optionally, a third monolithic layer may be employed. The adsorption zone is typically contained in an adsorption vessel.

Adsorption processes

An improved method for preparing and activating monolith adsorbents is disclosed. A regeneration gas is passed through the formed monolith adsorbent at a temperature sufficient to decompose at least part of the binding agents in the adsorbent. The present invention also provides for the use of the treated adsorbent monoliths in separating gases in cyclical separation processes such as vacuum swing adsorption processes.

Activation processes for monolith adsorbents

A gas separation process comprising feeding a gaseous mixture comprising at least two components having different adsorption characteristics into an adsorption vessel containing at least one adsorbent material capable of preferentially adsorbing at least one of the gaseous components in the gaseous mixture and subjecting the gaseous mixture to non-cryogenic conditions which enable the preferentially adsorbable gaseous component in the gaseous mixture to adsorb onto the adsorbent material and separate from the non-adsorbed component in the gaseous mixture which pass through the adsorbent vessel wherein at least one adsorbent material in the adsorbent vessel comprises a composite particle having an inner core comprising a non-porous, non-adsorbent material and at least one outer layer comprising the adsorbent material. In another embodiment of the process of the present invention a hollow particulate adsorbent material is utilized.
