Title: Biography of Inventor Allan L Turner
Introduction: Allan L Turner is a notable inventor based in Lakewood, Colorado. He holds a total of 8 patents, showcasing his significant contributions to the field of chemical engineering and production methods.
Latest Patents: His latest patents include innovative methods for the production of sodium carbonate and sodium bicarbonate. One of his inventions involves a method for solution mining nahcolite, which is capable of extracting nahcolite from geological formations that are lean in nahcolite. This process includes injecting high-pressure water, which may consist of recycled aqueous solutions of bicarbonate and sodium carbonate, at temperatures of at least 250°F into the geological formation. The hot water dissolves nahcolite to form a production solution, which is then processed to provide sodium carbonate and, optionally, sodium bicarbonate. The processing steps include decomposing the sodium bicarbonate portion, evaporating water to form a concentrated solution, producing sodium carbonate monohydrate through crystallization, and finally dewatering and calcining the monohydrate to yield anhydrous sodium carbonate.
Career Highlights: Throughout his career, Allan has worked with various companies, including American Soda, LLP and Environmental Projects, Inc. His expertise in chemical processes has made him a valuable asset in these organizations.
Collaborations: Allan has collaborated with notable coworkers such as Max E Ramey and John S Mc
