alkali barium calcium abc

  • Barium is a silvery-white metal which exists in nature only in ores containing mixtures of elements It combines with other chemicals such as sulfur or carbon and oxygen to form barium compounds Barium compounds are used by the oil and gas industries to make drilling mudsBatch regeneration of barium carbonate (BaCO(3)) from barium sulphide (BaS) slurries by passing CO(2) gas into a pilot-scale bubbling column reactor under ambient conditions was used to assess the technical feasibility of BaCO(3) recovery in the Alkali Barium Calcium (ABC) desalination process and its use for sulphate removal from high sulphate Acid Mine Drainage (AMD).
