Title: Innovations of William A. Rendall
Introduction
William A. Rendall is a notable inventor based in Calgary, Canada. He has made significant contributions to the field of gas sweetening systems and enhanced oil recovery. With a total of 2 patents, his work has had a considerable impact on the industry.
Latest Patents
Rendall's latest patents include a method for purifying amine gas sweetening systems by the addition of CO₂. This innovative method involves removing dissolved solids or sludge from amine absorbing solutions for acidic gas. The process comprises contacting a stream of regenerated absorbing solution with CO₂, allowing the sludge to form a precipitate, which can then be removed from the absorbing solution. The regenerated absorbing solution can either be returned to a regenerator for CO₂ removal or sent back to the gas sweetening system.
Another significant patent is for surfactant-stabilized foams for enhanced oil recovery. This foam is designed for use in subterranean oil-bearing formations to reduce and control the mobility of a gaseous drive fluid. The foam is generated using an inert gas and a fluorocarbon surfactant solution mixed with an amphoteric or anionic hydrocarbon surfactant solution. The combination results in a foam that exhibits better stability when in contact with oil compared to foams made with hydrocarbon surfactants alone.
