Title: Dale Lee Denham, Jr.: Innovator in Sodium Carbonate Production
Introduction
Dale Lee Denham, Jr. is a notable inventor based in Arvada, Colorado. He has made significant contributions to the field of chemical engineering, particularly in the production of sodium carbonate. With a total of 7 patents to his name, Denham has demonstrated a commitment to innovation and efficiency in his work.
Latest Patents
Denham's latest patents include a process for the production of sodium carbonate and a recrystallization process. The sodium carbonate production process involves heating a feed stream containing trona and insoluble impurities in a calcining apparatus to a temperature of less than about 350°C. This process results in the formation of anhydrous sodium carbonate, which is then contacted with a saturated sodium carbonate brine solution to create sodium carbonate monohydrate crystals. These crystals are subsequently separated from insoluble impurities.
The recrystallization process provides a method for producing crystals of a polymorphic compound in a first crystal structure. This is achieved by introducing the compound in a second crystal structure into a saturated brine solution under conditions that favor the formation of the first crystal structure. The process controls supersaturation and its relief to promote the growth of existing crystals rather than the nucleation of new ones.
