A taking up/receiving system (100) and a process for taking up/receiving of gas from a medical apparatus (1) are provided. The taking up/receiving system includes a feed line (6), a discharge line (8), a filter unit (4) with a filter and at least one buffer storage device. The feed line establishes a fluid connection between the medical apparatus and the filter unit. The discharge line establishes a fluid connection between the filter unit and a fluid taking up/receiving unit (7). The gas is discharged from the medical apparatus and is passed through the feed line to the filter unit and from there through the discharge line to the fluid taking up/receiving unit. The filter filters at least one gas component out of the gas that is passed through the filter unit. The one or more buffer storage device absorbs and again discharges gas from time to time.

A gas recycle system includes a gas purifier system; a gas analysis system; a gas blending system that prepares a recycled gas mixture; and a control system configured to: determine whether a measured amount of at least one intended gas component is within a first range of acceptable values; and determine whether a measured amount of the at least one impurity gas component is within a second range of acceptable values. If the measured amount of the at least one intended gas component is not within the first range of acceptable values, the control system causes the gas blending system to add an additional gas component to the purified gas mixture to prepare the recycled gas mixture; and if the measured amount of the at least one impurity gas is not within the second range of acceptable values, the control system generates an error signal.

A gas chamber supply system includes a gas source configured to fluidly connect to a gas chamber and to supply a gas mixture to the gas chamber, the gas source including: a pre-prepared gas supply including a gas mixture, the gas mixture including a plurality of gas components and lacking a halogen; a recycled gas supply including the gas mixture; and a fluid flow switch connected to the pre-prepared gas supply and to the recycled gas supply. The gas chamber supply also includes a control system configured to: determine if the relative concentration between the gas components within the recycled gas supply is within an acceptable range; and provide a signal to the fluid flow switch to thereby select one of the pre-prepared gas supply and the recycled gas supply to as the gas source based on the determination.

A gas treatment system includes a first scrubber configured to treat a gas exhausted from a process chamber, a catalytic reactor connected to the first scrubber and configured to treat a gas passing through the first scrubber, and a second scrubber connected to the catalytic reactor and configured to treat a gas passing through the catalytic reactor, where the catalytic reactor includes a fluidized bed reactor (FBR).

Technologies for combusting hazardous compounds such as chemical warfare agents and related compounds are disclosed. In embodiments, the technologies include systems and methods for combusting such compounds in an internal combustion engine, such as a spark ignition internal combustion engine, a diesel engine, or the like. The technologies described herein further include components for treating an exhaust gas stream produced by combustion of hazardous compounds. In embodiments such components include a scrubber that utilizes a scrubbing media such as soil to removing acid gases from the exhaust stream.

An exhaust-gas treatment apparatus capable of efficiently making a harmful gas containing in an exhaust gas harmless without increasing a size of the apparatus is disclosed. The exhaust-gas treatment apparatus includes a main body in which a flow passage is formed for a liquid to flow, an exhaust-gas supply line to be coupled to the main body, and for supplying the exhaust gas to the flow passage through which the liquid flows, a suction device configured to suck the exhaust gas from the exhaust-gas supply line into the flow passage, a low-temperature plasma generator for generating low-temperature plasma in the flow passage to decompose the harmful gas, and a discharge line for discharging the exhaust gas, which has passed through the low-temperature plasma generator, from the main body.

A process for treating a composition comprising one or more desired (hydro)fluoroolefins and one or more undesired halogenated ethanes, halogenated methanes or mixtures thereof so as to reduce the concentration of at least one undesired halogenated ethane or halogenated methane, the process comprising contacting the composition with an adsorbent comprising pores having openings which have a size across their largest dimension of about 6 A or less.

A method of delivering or sequestering anesthetic agents by adsorption of such agents by porous partially fluorinated compounds which display high weight adsorption capacities. Such compounds have a non-covalent organic framework with a central ring, such as hexa, tetra, tri or di substituted benzenes which may be substituted or unsubstituted with alternating electron poor and electron rich groups such as tetra-, tri-, or di-fluorobenzenes, oligocyanobenzenes, oligochlorobenzene, and benzene, pirydone, triazole, pyrazole, pyridine, and substituted benzenes so that the compound forms a porous supramolecular structure; and adsorbs the anesthetic agent within the pores of a the compound.

Cavitand compositions that comprise void spaces are disclosed. The void spaces may be empty, which means that voids are free of guest molecules or atoms, or the void spaces may comprise guest molecules or atoms that are normally in their gas phase at standard temperature and pressure. These cavitands may be useful for industrial applications, such as the separation or storage of gasses. Novel cavitand compounds are also disclosed.

An anaesthetic halocarbon capture system is provided. The system comprises a pressure-intolerant sleeve containing filter material for capturing one or more types of anaesthetic halocarbon prior to supercritical fluid extraction, and a pressure-tolerant housing into which the sleeve can be inserted so as to permit exposure of the sleeve contents to pressures required for supercritical fluid extraction.
