    摘要: Certain Mannich reaction products formed from the reaction of an alkyl substituted catechol, a polyamine, and an aldehyde are used to deactivate copper metal species contained in hydrocarbon fluids. Left untreated, such copper species lead to decomposition resulting in the formation of gummy, polymer masses in the hydrocarbon liquid.

    摘要: Certain Mannich reaction products (i.e., alkylated phenol, polyoxyalkylenediamine, and an aldehyde) are used to deactivate iron species already present in hydrocarbon fluids. Left untreated, such iron species lead to decomposition resulting in the formation of gummy, polymer masses in the hydrocarbon liquid.

    摘要: Methods of extracting iron species, such as iron naphthenate, and iron sulfides, from a liquid hydrocarbon, such as crude oil are disclosed. A chelant selected from oxalic or citric acid is added directly to the liquid hydrocarbon and mixed therewith. Then, wash water is added to form a water in oil emulsion. The emulsion is resolved, with iron laden aqueous phase being separated.

    摘要: An oxygen scavenger for aqueous mediums is disclosed. The oxygen scavengers comprise cyclohexanediones which, when added to basic aqueous solutions, effectively scavenge oxygen from the aqueous solutions. The oxygen scavenger has particular utility as an oxygen scavenger from water in heating systems such as boilers and heat exchangers.
