In cases where acetic acid is used, Citric acid monohydrate is added to the emulsion prior to gassing, the desired amount of acid is mixed in the emulsion, before adding the gasser.
A gassing solution comprising sodium nitrite in water together with the selected enol compound and acetic acid is introduced into the emulsion explosive at the blast hole by entraining the gassing solution into a stream of the emulsion explosive using pumps.
The solution pH is an important parameter in the gassing of emulsion explosives due to the high cost associated with acid addition therefore a pH value should preferably be maintained at 4.1 or below.
