Title: Improvements in or relating to the dehydration of coal tar and similar products by distillation
IPC: C10C1/02
Filed: 1947-09-17
Abstract: <PICT:0640178/III/1> Crude coal tar or similar products are dehydrated by azeotropic distillation using an added light hydrocarbon oil, such as benzol, as water-entrainer.  After condensation of the vapours and separation of water from the condensate, the light oil is recycled to the still in admixture with the crude tar. Dehydration down to a water content of only 0.1 per cent is thereby carried out at a low temperature, i.e. close to 100 DEG  C.; and foaming is eliminated.  The tar may be dehydrated in column 3 which is fitted with a steam-heater 4 and perforated splash-plates 5.  The top of the column is connected to a condenser 9 and decanter 11.  Tank 1, to which the crude tar is supplied, is connected to the side of the column by two routes; one contains a pump 2 for supplying feed to the column, while the other is for the return of overflow from the constant liquid-level in the column. About 100 litres of light oil is added for every cubic meter of tar in the column, and the temperature of the liquid is raised to 100-110 DEG  C. to distil off the azeotropic mixture.  The vapours are condensed and the condensate is decanted; water being discharged through pipe 12, while the light oil is passed to tank 1 through pipe 13.  Dehydrated tar is withdrawn from the base of column 3 through pipe 8.
