Latest Patents

Sonia holds a patent for a method titled "Method for the thermo-chemical dewaxing of large dimension lines." This method utilizes a Nitrogen Generation System/Emulsion to effectively remove wax from conduits. The process involves introducing an emulsion that contains an internal aqueous phase and an external organic phase into the conduit. The aqueous phase consists of oxidizing and reducing nitrogen salts, while the organic phase includes a non-polar organic liquid, such as kerosine. The innovative use of a delayed action activator, such as poly(adipic anhydride), allows for the generation of nitrogen and heat, which fluidizes the wax for easy removal. This method not only enhances efficiency but also allows for the resumption of well production after treatment.
