Abstract: A method of accessing and cleaning an interior portion of a gas scrubber canister in-situ. A removable glass member is attachable to a flange formed on the canister. By removing the removable glass member an access port in communication with the interior portion of the canister is provided. A vacuum device is insertable through the access port to clean the interior portion in-situ.

Abstract: A method and system for predicting the end of life of a packed resin or dry chemical bed in a gas scrubber including providing a plurality of thermocouples spacedly disposed in the packed bed, the thermocouples being operatively coupled to a processor, monitoring the motion of an exothermic wavefront through the packed resin or dry chemical bed by periodically sampling the thermocouples and computing a time at which the exothermic wavefront will have traversed the packed resin or dry chemical bed, the computed time being the end of life of the packed resin or dry chemical bed.

Abstract: The invention relates to an improved apparatus for thermal management in a gas purification process. As known in the prior art, a gas purification apparatus includes a two-section unitary vessel, wherein the primary section includes an impure gas inlet and a heating assembly and the secondary section includes a cooling device and an outlet for purified gas. Within the primary and secondary sections of the vessels are gas sorbing materials such as getters for removing impurities from the gas to be purified. A feature of the present invention is the continuous, serpentine shape of the gas purification vessel which allows for a longer residence time of the gas and a more efficient purification process. Another feature of the invention is a Joule-Thomson cooling device which divides the primary section of the vessel from the secondary section. The Joule-Thomson cooling device cools the secondary section of the vessel and the gas contained within it.
