Abstract

Fractional condensation of a vapour mixture comprising steam and a higher boiling component, e.g. the vapour mixture from the steam distillation of tar acids, is effected by introducing the mixture at subatmospheric pressure into a surface condenser maintained at a temperature above the condensing temperature of steam but below that of the higher boiling component whereby the latter is condensed, passing <PICT:0703476/III/1> the residual steam to a second condenser, e.g. a spray type condenser, and effecting cooling of the first condenser at least partly by means of the condensate from the second condenser. If a mixture of steam and tar acid vapours at an absolute pressure of 2" Hg. is introduced into a surface condenser supplied with cooling-water maintained at 40 DEG C., the tar acid condensate contains only 1.3 per cent. water, while the vapours passing to the second condenser contain only 1.7 per cent. tar acid. If the temperature of the first condenser is increased, the water content of the tar acid is even less. A vapour mixture, containing steam and a higher boiling component, is introduced through pipe 1 into surface condenser 2. Cooling water is supplied to, and discharged from, condenser 2 through pipes 3 and 4, respectively. The condensate of the higher boiling component, formed in condenser 2, is separated from steam in separator 6, and is then withdrawn from the system through pipe 7. The steam is passed from separator 6 into jet condenser 9, where it is condensed by contact with water from spray 10. The flow of water delivered by the spray is regulated, by valve 13, controller 14 and temperature-responsive element 15, so that the temperature of the water discharged from the condenser through outlet 12, is only a few degrees below the boiling point at the pressure within the condenser. This outlet water passes to a tank 16 where it is heated by steam, injected in automatically controlled amounts through pipe 17, so as to maintain the water at the temperature required for condenser 2. The water is pumped from tank 16 to condenser 2 through pipe 3. If the load on condenser 2 is greater than that on condenser 9, extra water is added through pipe 35.
