Title Sorbents for harmful gases generated during arc welding
Original title Sorbenty do pochłaniania szkodliwych dla zdrowia gazˇw powstających przy spawaniu łukowym [in Polish]
Bibliographic information 1983, Vol.33, No.116, p.17-28. Illus. 12 ref.
Abstract The ability of molecular sieves 13X and 5A to adsorb nitrogen oxides was determined. Adsorption isotherms and the empirical constants of the Brunauer-Emmet-Teller equation were determined. Absorber operation under industrial conditions was analysed on the basis of the adsorption isotherms. Resistance to flow was measured, and resistance coefficients were calculated and compared with theoretical values. Molecular sieve 13X appears to be preferable for cleaning the air stream of extractive ventilation systems used during welding with coated electrodes.
