Abstract:
The physical and chemical fixation and stabilization of waste products from a sulfur-fuel burning unit through controlled crystallization of dissolved calcium sulfite. A low pH calcium sulfite solution is added to the waste containing aqueous sludge produced by a gas desulfurization unit thereby raising the pH of the calcium sulfite to crystalize the calcium sulfite and bind and encapsulate the waste products into a solid mass.
