ABSTRACT:
A process to control the addition of excess carbonate to brine systems is provided wherein the process measures the raw brine flow rate through the carbonate reactors, the concentration of calcium in the brine feeding the reactors and the concentration of carbonate in the sodium carbonate feed tank to calculate the quantity of sodium carbonate necessary to remove substantially all of the calcium impurity in the brine by precipitating it out as a calcium carbonate flocculant. The process is automated and employs an information feed forward system.
