Latest Patents

One of his latest patents is a method for producing zinc bromide. This method involves making zinc bromide from metallic zinc and bromine by contacting zinc with bromine dissolved in a reaction solvent containing a metal halide salt. The reaction temperature is maintained at less than 60 degrees Celsius. The reaction solvent preferably comprises an alkali, alkaline earth, or transition metal halide, with the halide salt being either a chloride or a bromide. A preferred method includes recirculating the zinc bromide product stream back to the reaction vessel, which can be either a one-stage or multiple-stage reactor. The resulting product stream comprises a high-density zinc bromide solution.

Another significant patent by Hanlon is a method for manufacturing clear brine fluids from impure zinc feedstock. This method utilizes zinc byproducts in the production of clear brine fluids by mixing zinc feedstock containing metal impurities with a halogenic acid to create an impure zinc halide solution. The metal impurities are removed through a two-stage process, which includes precipitating and filtering out manganese and iron, followed by contacting the zinc halide solution with elemental zinc to cement out remaining metals such as nickel, lead, cadmium, copper, mercury, and cobalt. The pH is adjusted as necessary to maintain optimal conditions during the process.
