FGD gypsum dewatering improvement through crystal habit modification by carboxylic acids

   
   

A flue gas desulfurization process is disclosed. Specifically the use of carboxylic acids to modify gypsum crystal habit in limestone forced oxidation. The technique is also applicable to other technologies where gypsum is produced as for example in phosphate fertilizer or paper industry.

Se divulga un proceso de la desulfurización del humo. Específicamente el uso de ácidos carboxylic de modificar el hábito cristalino del yeso en piedra caliza forzó la oxidación. La técnica es también aplicable a otras tecnologías donde el yeso se produce como por ejemplo en fertilizante del fosfato o la industria de papel.
