  • Method and apparatus for dividing the flow of a gas stream
    Patent number: 6895983
    Abstract: An apparatus for dividing the flow of a gas stream and a method for controlling the flow division of a gas stream are disclosed, the apparatus including an inlet conduit for receiving the gas stream, outlet conduits in fluid communication with the inlet conduit for delivering the gas stream, a balancing gas feed conduit in fluid communication with an outlet conduit, a balancing gas feeder in fluid communication with the balancing gas feed conduit, and a balancing gas controller; and the method including the steps of dividing the process gas stream into process gas stream fractions and injecting a balancing gas stream into a process gas stream fraction in an amount sufficient to displace a portion of gas flow from the process gas stream fraction into one or more remaining process gas stream fractions.

  • Method for quantitative production of gaseous ammonia
    Publication number: 20020159942
    Abstract: A process for producing an ammonia-containing gaseous product from aqueous ammonia including the steps of transporting concentrated aqueous ammonia from a source location to a location of use remote from the source location, vaporizing a portion of ammonia from the aqueous ammonia to produce an ammonia-containing gaseous product and a dilute aqueous ammonia remainder, and transporting the dilute aqueous ammonia remainder to a return location, is disclosed.
