CoLD® Process Shale Produced Water Veolia

a causticizing process is done by reacting the heated carbonated solution of proper strength with lime. The lime was made in unslaked condition in order to utilize the heat of the reaction. After agitation from 0.5 to 1.5 hours the suspension is allowed to settle for 0.5 hour. The caustic soda solution obtained from such reaction has a concentration of 81.99g/l and 119.66gm/l, with molarities
