Abstract: A process for distilling an aqueous NPG mixture comprising NPG, a tertiary amine, water and the adduct of tertiary amine and formic acid (amine formate), said distillation being performed in a distillation column, which comprises drawing off a gaseous stream in the upper region of the column and feeding it to two condensers connected in series, the first condenser being operated in such a way that a portion of the gaseous stream is condensed in the first condenser and the second condenser being operated in such a way that the uncondensed portion of the gaseous stream is essentially fully condensed in the second condenser, the condensed stream from the first condenser being recycled fully or partly as reflux into the column.

Abstract: Gravity sedimentation of a first aqueous suspension of solid particles in a vessel results in formation of a second aqueous suspension of solid particles in the present invention. The process involves adding at least one organic polymeric flocculant to the first aqueous suspension to form a suspension of flocculated solid. The flocculated solids settle to form a bed of consolidated solids. Introducing an effective amount of an agent into the bed of consolidated solids or into the flocculated solids that are settling leads to formation of the second aqueous suspension. The second aqueous suspension of solid particles has a higher solids content than the first aqueous suspension of solid particles. The agent is a free radical agent or an oxidizing agent.
