Sodium Carbonate And Sodium Bicarbonate Production From Nahcolitic Oil Shale
US Patent:
6609761, Aug 26, 2003
Filed:
Jan 10, 2000
Appl. No.:
09/480092
Inventors:
Max E. Ramey - Rifle CO
John S. McEwan - Parachute CO
Kevin L. Green - Parachute CO
Charles L. Yates - Parachute CO
Allan L. Turner - Lakewood CO
Irvin P. Nielsen - Rifle CO
Michael P. Hardy - Grand Junction CO

Assignee:
American Soda, LLP - Parachute CO
International Classification:
F21C 4116
US Classification:
299 5, 4232062
Abstract:
A method for solution mining nahcolite, capable of extracting nahcolite from geological formations lean in nahcolite comprising injecting high pressure water (which may include recycled aqueous solution of bicarb and sodium carbonate) at a temperature of at least 250° F. into the formation, dissolving nahcolite in the hot water to form a production solution and recovering the production solution. The invention also includes the processing of the production solution to provide sodium carbonate and, optionally, sodium bicarbonate, comprising: decomposing the sodium bicarbonate portion of the hot aqueous production solution to form a hot aqueous solution of sodium carbonate; evaporating water from the hot aqueous solution comprising sodium carbonate to form a concentrated solution of sodium carbonate; producing sodium carbonate monohydrate from the concentrated solution of sodium carbonate by crystallization; and dewatering and calcining the sodium carbonate monohydrate to produce anhydrous sodium carbonate.
