Abstract: Peroxyformic acid compositions for treatment and removal of biofilm growth and mineral deposits on membranes for energy services applications are disclosed. In particular, peroxyformic acid compositions are generated in situ or on site generation for the reduction and prevention, of biofilms and the mitigation of mineral buildup on the membranes. The compositions according to the invention are compatible with the membranes under application of use conditions.

Abstract: Peroxyformic acid compositions for removal of biofilm growth and other contaminants and impurities from industrial processing hard surfaces are disclosed. In particular, peroxyformic acid compositions may be dosed on site and/or generated in situ for the reduction and prevention of biofilms on the hard surfaces. Methods of employing the peroxyformic acid compositions for removal of biofilm growth and other impurities such as aldehydes and alcohols from industrial CO2 effluent are also disclosed which beneficially provide ambient biofilm control and break down more rapidly than other peracids, allowing for extended runs between CIP cleaning, including a reduction and/or elimination of cleaning of the scrubbers and other industrial surfaces.

Abstract: The present invention relates generally to methods for forming peroxyformic acid, comprising contacting formic acid with hydrogen peroxide. The methods for forming peroxyformic acid can include adding formic acid with a relatively lower concentration of hydrogen peroxide, or adding formic acid to a peroxycarboxylic acid composition or forming composition to react with hydrogen peroxide in the compositions. The present invention also relates to peroxyformic acid formed by the above methods. The present invention further relates to the uses of peroxyformic acid for treating a variety of targets, e.g., target water, including target water used in connection with oil- and gas-field operations. The present invention further relates to methods for reducing or removing H2S or iron sulfide in the treated water source, improving clarity of the treated water source, or reducing the total dissolved oxygen or corrosion in the treated water source, using peroxyformic acid, including peroxyformic acid generated in situ.

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.

Abstract: Antimicrobial compositions including at least one acid and at least one anionic surfactant are provided. In particular, food contact antimicrobial compositions including at least one acid and at least one anionic surfactant provide efficacious virucidal activity, including against Norovirus, having acceptable use solution pH that do not require use of personal protective equipment (PPE), are surface compatible and do not leave residues on treated surfaces. Methods of cleaning a surface with the compositions are also provided and may beneficially eliminate the need to rinse the antimicrobial compositions after use.
