    摘要: A pressure-swing adsorption (PSA) system includes a plurality of substantially similar pairs of towers, each tower containing adsorbent material for separating a gas into components. Each tower has a top header and the bottom headers, the headers being connected to extensions which define conduit segments. When a new pair of towers is placed alongside an existing pair of towers, the conduit segments are aligned to define longer conduits spanning all of the pairs of towers. Thus, the longer conduits can be used to direct gas into towers from all of the pairs, and to withdraw product gas from towers in all of the pairs. The capacity of the PSA system can thus be easily expanded or reduced. Some or all of the piping used to direct gas to and from the towers is replaced by one or more control blocks, which define passages for gas flow.

    摘要: A system and method for rehabilitating a water well using compressed nitrogen. The method includes compressing air to a first pressure higher than atmospheric pressure; providing the air at the first pressure to a nitrogen generator; removing oxygen from the air, resulting in a nitrogen gas having at least 80% nitrogen; compressing the nitrogen gas to a second pressure higher than the first pressure; inserting a venting apparatus into the bore; and discharging the pressurized nitrogen gas into the bore. In another aspect, a different method of treating a water well is disclosed. The method comprises providing a tank of pressurized nitrogen gas; inserting a venting apparatus into the bore; discharging the pressurized nitrogen gas into the bore; depleting the pressure of the nitrogen gas in the tank to produce low-pressure nitrogen; re-pressurizing the low-pressure nitrogen to a desired pressure; and discharging the re-pressurized nitrogen gas into the bore.

    摘要: A system and method for recovering a sterilization agent from waste gaseous mixture, comprising a gas separator to wash waste gas comprising a gaseous mixture of a sterilization agent, insert dilution gases, and water vapor, from plurality sterilization chambers, with water, thereby producing a water-gaseous sterilization agent mixture collected at bottom section of the gas separator, and inert dilution gases exhausted at top section of the gas separator; a pressure reducing valve; a first tank or gas evaporator to produce gaseous sterilization agent and water vapor; a first condenser to produce condensed water vapor and separate the gaseous sterilization agent from the condensed water vapor; a water tank to receive the condensed water vapor; a separation pump for raising pressure of the gaseous sterilization agent; a second condenser to cool the gaseous sterilization agent causing the sterilization agent to condense into liquid; and a second tank for storing the liquid sterilization agent.
