Mass Transfer For a binary mixture with low relative volatility, Use molecular distillation Use high pressure distillation An azeotrope may be formed during distillation Use steam distillation Use molecular distillation Use high pressure distillation An azeotrope may be formed during distillation Use steam distillation ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Temperature is less Total pressure is less Saturated steam is used for steam distillation Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Temperature is less Total pressure is less Saturated steam is used for steam distillation ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer The binary diffusivity in gases at atmospheric conditions is about 10-9 cm/sec 10-1 cm²/sec 10-4 cm²/seC₂ 10-3 sec/cm 10-9 cm/sec 10-1 cm²/sec 10-4 cm²/seC₂ 10-3 sec/cm ANSWER DOWNLOAD EXAMIANS APP
