Patent FR-2509622-A1 (FR)
Inventor: GUTWASSER HELMUT
IPC: C07C51/44
Filed: 1982-07-16
Abstract: A process and an apparatus are described for the continuous rectification with minimum consumption of energy and material of, in particular, mixtures having a plurality and a multiplicity of substances, and temperature-sensitive substances, preferably having relatively low volatility. The invention is characterised in that the majority of the reflux resulting from the circulation of the liquid amounts present in the column system is delivered at the column head and as a result the ratio of the reflux amounts to be evaporated and distillate amounts corresponds to the values of the minimum reflux ratio or even smaller values. As a result of partial condensation at inner and outer mass transfer surfaces and, depending on the position of the cut and the partial pressure differences (alpha value), a one to many-fold reboiling of the partial condensates at the inner surfaces, a low pressure drop and a small apparatus height - the latter decreases with decreasing feed concentration at constant high end concentration - are achieved. The invention can be used in particular for vacuum distillations for further processing of thermally sensitive mixtures containing a plurality and a multiplicity of substances.
