    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 H 2 S 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: The invention relates to a method for the continuous production of a mixture of substances or a reaction mixture formed by the reaction of components contained therein. The component fluxes drawn from a storage container (1, 2 or 3) or a distribution network (12) are respectively channelled via a control path (22, 23, 24, 25), each path comprising a flowmeter device (8, 9, 10, 11) and a control organ (34, 35, 36, 37). The mass fluxes of the individual components are controlled in proportion to the mass flux of a first component. The resultant controlled mass fluxes are introduced into a reservoir either directly, or once the individual mass fluxes have been partially or fully combined. The method and the device are particularly suitable for the on-site production of non-transportable mixtures of substances, or mixtures of substances that are costly to transport, such as highly concentrated peroxycarboxylic acid solutions.
