Title Neutralising the acidity of the exhaust gases of internal combustion engines
Original title Neutralisation de l'acidité des gaz d'échappement des moteurs à combustion interne. [in French]
Bibliographic information May-June 1975, No.3, p.112-115. Illus.
Abstract The acidity of the gases emitted by internal combustion engines constitutes a health hazard for workers in their vicinity. Use of water tanks or baths to dissolve the acids may lead to the opposite of the result sought, when the acid saturation point is reached. To overcome this danger, a neutralising product should be added to the water. Tests were carried out with iron ore limestone, lime and chalk; the results showed that chalk was the best additive. Even when a neutralising product is added, tanks and vats should be rinsed out daily and pH readings of the solution should be constantly taken.
