Dissolved solids in the tar from the bottom of a distillation column are precipitated by quenching the hot tar in oil. The solids are then separated from the oil and burnt. The density of the solids is 1100 kg/m3 . The density of the liquid phase after addition of the tar is 860 kg/m3 and its viscosity, at the temperature of the mixture, is 1.7 mN m-2 s. The solid content of the oil and tar mixture is 10% and the flow rate of the liquid phase leaving the separator will be 1000 kg/h. The cutoff particle size required is 0.1 mm.

List the types of separator that could be considered for. Bearing in mind the nature of the process, what type of separator would you recommend for this duty?separating the solids from the liquid
