He has made significant contributions to the field of chemical engineering, particularly in processes related to pulp and paper production. With a total of three patents to his name, his work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is titled "Process for the conversion of calcium sulfide." This patent describes a method for removing solid CaS from a gas stream and converting it by reacting with an aqueous NaOH solution to produce solid Ca(OH)₂ and a liquor stream containing dissolved NaHS. This innovative process is particularly useful in conjunction with gasifying black liquor from a kraft pulping process, where H₂S is scrubbed from gases using calcium compounds to form CaS.
Another significant patent is "Ozone dioxane bleaching of chemical pulps." This method involves bleaching chemical pulp with a gaseous bleaching agent by uniformly impregnating the pulp with a solvent for lignin that is fully miscible with water but does not significantly swell cellulose. This approach improves the availability of lignin to the bleaching agent, allowing for preferential attack and subsequent solubilization and separation from the pulp.
