Patent number: 11155927Abstract: Corrosion inhibitor compositions are provided that can include a mixture of one or more transition metals, one or more organic phosphates, one or more inorganic phosphates, optionally a dispersant, and hydroxyphosphono acetic acid and/or salts thereof. Methods of mitigating or inhibiting corrosion of housing or conduits containing aqueous mediums are also disclosed. The methods can include the steps of pretreating the metal conduit with a mixture of one or more transition metals, one or more organic phosphates, one or more inorganic phosphates, and hydroxyphosphono acetic acid, introducing an aqueous medium into the metal conduit, and injecting a mixture of one or more transition metals, one or more organic phosphates, one or more inorganic phosphates, and hydroxyphosphono acetic acid and/or salts thereof into the aqueous medium.Type: GrantFiled: September 4, 2019Date of Patent: October 26, 2021Assignee: ECOLAB USA INC.Inventors: Jasbir S.

Patent number: 10767090Abstract: The invention is directed towards methods and compositions for treating piles of particulate materials to inhibit and prevent the loss of valuable fuel or mineral dust from being released from storage piles or open containers. The method involves applying separately to the pile two different compositions. When separate the two compositions are low viscosity and easy to spray. When combined the two form a gel coating that is resistant to erosion but is flexible while the pile or payload is still settling, jostling, being bumped, and otherwise moving around. This coating is especially effective for coal piles, iron ore piles, and also for piles within and/or being moved by open topped railroad cars. The coating's flexibility prevents the coating from becoming brittle and shattering. The coating has better performance than its ingredients do alone. As a result the invention can both prevent unwanted dust pollution as well as save its users money by avoiding loss of blown away material.Type: GrantFiled: February 27, 2017Date of Patent: September 8, 2020Assignee: Ecolab USA Inc.Inventors: Danilo Zim, Fabio Peixoto Macedo Gomes

Patent number: 9909219Abstract: The invention provides methods and compositions for addressing the problem of microorganism infestations and especially biocorrosion in slurry transporting pipelines. The method comprises treating pipeline fluid (especially plug fluid) with an oxidizing biocide in an amount higher than the oxidant demand of the pipeline and a non-oxidizing biocide in an amount less than 30% of the minimum necessary to sterilize the microbiological organisms. This treatment makes use of the unique characteristics of a slurry pipeline to eliminate microorganisms without harming the pipeline as would be expected by using an oxidizing biocide.Type: GrantFiled: April 14, 2014Date of Patent: March 6, 2018Assignee: Ecolab USA Inc.Inventors: Michael G. Strominger, Danilo Zim, Fabiane Cássia de Sá Aureliano

Patent number: 8557338Abstract: This invention is directed to a method of inhibiting corrosion-erosion in pipelines carry slurries. The method includes contacting for a period of at least 1 hour an inner surface of the pipeline with a composition of matter, the composition being at least one corrosion inhibitor within a water solvent, purging the pipeline of the water, and then transporting a slurry through the pipeline. This method is surprisingly effective because it prevents erosion with materials that were previously known to not have any effect on erosion. In addition it is effective on especially hard slurries such as bauxite for which previous uses of these inhibitors did not prevent erosion.Type: GrantFiled: October 29, 2012Date of Patent: October 15, 2013Assignee: Ecolab USA Inc.Inventors: Danilo Zim, Matheus P Paschoalino, Rafaela F.
