TH181064A - Chemical recovery methods for pulping from dissolved ash. Which has a high carbonate content - Google Patents

Abstract

------ 01/02/2018 ------ (OCR) page 1 of number 1 page invention summary A method of applying a chemical compound for the production of wood pulp from the dark rubber oil produced in Wood pulp production process, where this process leads to the burning of black latex in a chemical boiler. As a result, the ash forms contain high amounts of carbonates as well as sodium, potassium and chloride. This ash was dissolved to form a solution. This ash was dissolved and then 'was watered. Going straight to the crystallization unit phase, one th 'thickened the thawed ash solution, and This resulted in the precipitation of sodium sylphate and sodium carbonate. Hungry from the concentrated dissolved ash solution was directed to the second phase crystallization unit, which made Let the dissolved ash solution be concentrated, cooled in a single-batic form to form a slurry. Glycerite and chloride-rich removal currents to reduce the tendency of sodium carbonate and burkeite to crystallize in the second phase of crystallization units and to In addition to the gla cherai, the liver was crystallized in the crystallization medium. This approach brings mixing Sylphate source, for example sodium sulfate.

This ash was dissolved to form a dissolved ash solution that was then dissolved. Directly to the first crystallization unit, which concentrates the dissolved ash solution and This resulted in the precipitation of sodium sulphate and sodium carbonate. The concentrated ash solution was then directed to the second phase of crystallization unit. Cool the diluted ash slurry to form a thick slurry. Glaserite and chloride-rich removal currents to reduce the tendency of sodium carbonate and burkeite (burkeite) to crystallize in the second crystallization unit, and to Encourage the purified glaserite to crystallize in the crystallizer.
