Separation of lignosulfonates from sulfite spent liquor The spent liquor of the sulfite pulping process is dilute and contains other impurities; therefore, lignosulfonates should be separated from the spent liquor for increased commercial value. Because lignosulfonates are water-soluble products, they may not be precipitated by …

Lignosulfonates from sulfite spent liquor Lignosulfonates stem from sulfite pulping processes, which are typically characterized by the pH of the processes and the bases used. The typical pH of the sulfite pulping process ranges from 1 to 5; neutral sulfite semichemical pulping (NSSC) processes are …

Sodium lignosulfonat is an anionic surfactant that has good potential for enhanced oil recovery (EOR). Surfactants based on sodium lignosulfonate (NaLS) are selected because they can be synthesized from renewable materials, available raw materials, relatively cheaper than other surfactants, and are environmentally friendly. Previous studies …

Production Description Magnesium Lignosulfonate(Magnesium Lignosulphonate) is extracted from  pulping liquid  by the procedures of purification, evaporation, chemical treatment and drying.Could used as water reducing agent of concrete, Additive of coal water slurry, filler and dispersant of pesticide, reinforcing agent of refractory material and ceramics, Binder …

What is Calcium Lignosulfonate? Calcium lignosulfonate (Calcium Lignosulfonate)belongs to the class of organic compounds known as lignans, neolignans and related compounds. Calcium lignosulfonate is an extremely weak basic (essentially neutral) compound (based on its pKa). Calcium lignosulfonate is an odorless tasting compound. Calcium Lignosulfonate Structure …
