Assignee:

Ashland Inc. - Dublin OH

International Classification:

C23F 1500

US Classification:

422 15, 422 17, 25238921, 252180, 252390

Abstract:

This invention relates to an all-organic corrosion inhibiting composition comprising (a) 6,6,6-(1,3,5-triazine-2,4,6-triyltriimino) tris hexanoic acid; and (b) a water-soluble phosphonated oligomer salt. The invention also relates to a process for inhibiting corrosion in a closed recirculating cooling water system.

Appl. No.:

11/393823

Edward S. Beardwood - Newmarket, Ontario, CA
George F. Hays - Morristown NJ, US
Steven J. Colby - New Providence NJ, US
Dwight E. Emerich - Lincoln Park NJ, US

International Classification:

G01N 33/00

US Classification:

73 6162, 374 7

Abstract:

Novel methods for monitoring and recording fouling of aqueous systems are disclosed. The methods employ a heat transfer test assembly including an outer tube member, a heating rod positioned within the outer tube member, a ribbed tube sleeve fitted over the heating rod and thermocouples for sensing the wall temperature of heating rod. The heat transfer test assembly is connected to a monitoring and recording assembly that is connected to or includes a piping assembly. The piping assembly and the heat transfer test assembly are placed in fluid communication with a heat exchanger. Fouling determinations of fluid flowing through the piping assembly are made at varying flow rates with simultaneous monitoring and recording of the flow rates together with data, such as corrosion, pH, conductivity, and the like.

US Classification:

374007000, 165095000, 261155000, 261DIG011

Abstract:

This invention relates to a process for inhibiting the formation of biofilm and/or removing biofilm deposited on an enhanced tube of a heat exchanger in contact with an aqueous system. The process comprises feeding an oxidant selected from the group consisting of chlorine dioxide and stabilized bromine into an aqueous system such that the oxidant agent comes into contact with the enhanced tube.

Assignee:

LONZA, INC. - Allendale NJ

International Classification:

A01N 59/00

US Classification:

424723

Abstract:

Disclosed is an antimicrobial composition containing an active halogen-containing component having a source of an active halogen and having an elevated pH, which is mixed with an acidic component. An acidic component is added in an amount to the active halogen-containing component to reduce the pH of the antimicrobial composition. When the pH of the active halogen-containing composition is reduced, the resulting composition has been discovered to be effective as a disinfectant and, particularly, as a sporicide. Application methods for applying the composition are also described.
