Latest Patents
Lars Tage Uhlin holds a patent for a process designed to reduce the requirement of fresh chemicals without increasing emissions in the pulping of cellulosic material. This process involves evaporating and burning spent sulfate pulping liquor to obtain a smelt. The resulting smelt is dissolved in water to form a sodium-sulfide-sodium carbonate-containing solution known as green liquor. The process further includes regenerating pulping white liquor from this green liquor and recirculating it to the pulping stage. Additionally, it involves oxidizing the resulting liquors to form sodium thiosulfate, which is then reacted with residual acid liquor to convert thiosulfate to sulfur dioxide and sulfur. The formed sulfur dioxide is removed and recovered, while the residual liquor is returned to the pulping process.
