Abstract: In a continuous process for environment-friendly drying and purification of benzanthrone, the following process steps are applied: - charging a pumpable paste containing benzanthrone to a melt present in a stirred kettle, - dehydrating and melting the paste by means of steam, - condensing the water vapours emanating from the stirred kettle, - flaking off the melt present in the stirred kettle by means of a roll and - filling the flakes produced during flaking-off into a container.

Abstract: The invention relates to a method for carrying out the distillative separation of C5+ cuts into a low boiler fraction (A), a medium boiler fraction (B) and into a high boiler fraction (C) inside one or more partition columns (TK). A partition (T) is arranged inside said partition column(s) in a longitudinal direction of the column(s) while forming an upper common column area (1), a lower common column area (6), a feed part (2, 4) having a reinforcing part (2) and stripping part (4), as well as while forming a withdrawal part (3, 5) also having a reinforcing part (5) and stripping part (3). The inventive method involves the following steps: supplying the C5+ cuts (A, B, C) in the middle area of the feed part (2, 4); discharging the high boiler fraction (C) out of the bottom of the column; discharging the low boiler fraction (A) via the top of the column, and; discharging the middle boiler fraction (B) out of the middle area of the withdrawal part (3, 5). The dividing up ratio of the liquid reflux at the upper end of the partition (T) is set such that the proportion of high-boiling key constituents in the liquid reflux above the stripping part (3) of the withdrawal part at the upper end of the partition (T) ranges from 10 to 80 %, preferably, from 30 to 50 % of the limiting value permitted in the middle boiler fraction (B). In addition, the heating capacity in the bottom evaporator of the partition column (TK) is set such that the concentration of the light-boiling key constituents in the liquid at the lower end of the partition (T) ranges from 10 to 80 %, preferably, from 30 to 50 % of the limiting value permitted in the middle boiler fraction (B).
