Chrome free lignosulfonate are increasingly used in aqueous drilling fluids because of potential environmental concerns associated with the chromium counterparts. A basic design study of a chrome-free lignosulfonate showed three major reaction parameters affecting its performance: type and concentration of complexed metal ion. oxidation level under optimal pH and lignosulfonate raw liquor. A new chrome-free…
