Abstract: Systems for quenching peroxycarboxylic acid and peroxide chemistry runaway reactions provide safe and efficacious systems to prevent uncontrolled runaway reactions, such as decomposition reactions, of peroxycarboxylic acid and peroxide chemistry compositions are disclosed. The systems provide prompt detection and dispensing of a stabilizer into a tank or other storage vessel containing a peroxide composition, peroxycarboxylic acid composition or a peroxycarboxylic acid-forming composition to stop a runaway reaction. Methods for quenching peroxide and peroxycarboxylic acid runaway reactions are also disclosed.

Abstract: Methods and systems for temperature-controlled, on-site generation of peracids, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions are disclosed. In particular, methods for using an adjustable biocide formulator or generator system overcome the limitations of temperature on the kinetics of the peracid generation and/or peracid decomposition inside an adjustable biocide formulator or generator system. The methods include the controlling of the temperature of at least one raw starting material, namely water, to improve upon methods of on-site generation of peracids. The methods allow for the generation of user-selected chemistry without regard to the ambient temperatures of the raw starting materials and/or the biocide formulator or generator system.
