Abstract
233,964. Bollmann, H. June 12, 1924, [Convention date]. Column stills.-A distilling apparatus comprises a series of stages 2 - - 8 which are alternately provided with heated tubes through which the liquid trickles, the others 4, 6 having means for spreading the liquid over a large surface, e.g. Raschig rings, to facilitate disengagement of the vapours.
Process for the continuous distillation of hydrocarbons with simultaneous dissociation of high boiling point hydrocarbons into lower boiling point hydrocarbons
