Title: Sulfur oxide removal from gas
IPC: B01D53/50
Filed: 1979-10-01
Granted: 1984-02-15
Abstract: The principal object of the invention is to provide a method of removing SO2 from other gases by contacting SO2 with a soluble alkali metal base in a first zone at a pH not greater than 6 and thence in a second zone at a pH not lower than 6. Two zones (1, 4) are connected to each other and to a source of gas containing sulfur oxide as a pollutant to be removed. The gas is passed through the two zones in series and scrubbed with aqueous solutions. The pH level is controlled in each zone to minimize the amount of chemical added to the solutions and maximize the efficiency of the sulfur oxide removal.

Abstract: The package comprises a commercially available outer standard aerosol container equipped with a standard dispensing valve and a likewise commercially available inner standard aerosol container equipped with a standard dispensing valve. The inner container is arranged substantially coaxially with respect to the outer container, and such inner container is at a greater pressure than the outer container. Both of the dispensing valves of both containers are kinematically coupled in a manner such that upon normal actuation of the outer dispensing valve there is opened the inner dispensing valve. There are provided, for instance, latching cams or the like which retain the inner dispensing valve in its open position. After actuating the outer valve and thus also the inner valve the contents of the inner container empty into the outer container and admix with its contents. The mixture then can be removed in conventional fashion by means of the outer dispensing valve. Apart from the functional reliability and simplicity in handling of the two-compartment package such also exhibits an extremely simple construction, which particularly is realized by virtue of the fact that the package can be fabricated by extensively using standard components.
