Calculation of the plate efficiencies of foam apparatus for absorption and desorption processes

Reactive foams for air purification

“…Reactive foams have been used by Viles (1) and Silverman (2,3) to encapsulate air contaminated with radioactive materials and by Pozin (4) and Helsby and Birt (5) for absorption of C02. Several patents deal with the removal of nitrous oxides (6) or particles (7)(8)(9)(10) from air by a foam technique.…”
