  • Method and composition to decrease iron sulfide deposits in pipe lines
    Patent number: 6986358
    Abstract: The levels of iron sulfide present in a conduit, such as a pipeline, are reduced by contacting the conduit, on an inner surface, with a composition obtained from an aqueous solution containing at least one compound of Formula (I) and at least one amine or corresponding ammonium derivative in the presence of a solvent, wherein X is an anion of valency n. Preferably, the pH of the solution is about 8. Alternatively, the method employs a composition comprising tris(hydroxymethyl)phosphine (TRIS) and at least one amine or corresponding ammonium derivative. The amine preferably is ammonia or a primary alkylamine. The compositions readily complex and thereby dissolve deposits of iron(II) sulfide, removing them from the conduit.

  • Method to decrease iron sulfide deposits in pipe lines
    Patent number: 6866048
    Abstract: This invention provides a method of treating a dry or processed fluid pipe line susceptible to the build-up of iron sulfide deposits by complexing the iron sulfide in the pipe lines. The method of the present invention introduces the composition on a continuous or a batch basis to a gas pipe line. The composition is made of a solution of 1) water, 2) [tetrakis(hydroxymethyl)phosphonium]sulfate or chloride, and 3) a soluble ammonium salt, such as ammonium chloride or the like.
