Title: The Innovations of John G McCullough

Introduction

John G McCullough is a notable inventor based in Hawthorne, NY (US). He has made significant contributions to the field of gas treatment, holding a total of 3 patents. His work focuses on improving processes for purifying gas streams that contain acid gas impurities.

Latest Patents

One of his latest patents is the "Alkanolamine gas treating composition and process." This innovative composition consists of an alkanolamine solvent in an aqueous solution with antimony. The alkanolamine solvent includes at least about 1% by weight of methydiethanolamine (MDEA) and at least about 5% monoethanolamine (MEA) by weight of the total solution. The presence of antimony in a concentration of at least about 100 ppm helps inhibit corrosion and retards solvent degradation. Another significant patent is the "Alkanolamine gas treating process for a feedstream containing hydrogen." This process effectively removes acid gas from a feedstream containing hydrogen sulfide while maintaining solution concentrations of hydrogen sulfide and vanadium in the plus five valence state above certain minimum levels to reduce corrosion of steel components.
