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 translation: 本发明一般涉及形成过氧甲酸的方法，包括使甲酸与过氧化氢接触。 形成过氧甲酸的方法可以包括以较低浓度的过氧化氢加入甲酸，或将甲酸加入到过氧羧酸组合物中或形成组合物中以与组合物中的过氧化氢反应。 本发明还涉及通过上述方法形成的过氧甲酸。 本发明还涉及过氧甲酸用于处理各种靶物（例如目标水，包括与油气田操作有关的目标水）的用途。 本发明还涉及使用过氧甲酸（包括过氧甲酸）来减少或除去处理水源中的硫化氢或硫化铁的方法，提高处理水源的透明度或降低处理水源中的总溶解氧或腐蚀 原地生成。
