This setup is designed to study the performance characteristics of solvent extraction of a particular component from a packed bed of solid material. The apparatus allows study of such systems as water/inorganic salts, water/sugar bed, methylene chloride/vegetable oil etc. The glass column is fitted with SS mesh to support the solid material. The solvent is introduced near the bottom of the column and it flows upward counter-currently to the solids. A pump supplies the solvent and flow rate is monitored by means of a Rotameter. Solvent feed tank is kept in a bath fitted with heater and digital temperature controller is used to maintain the constant temperature

•An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.

•The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Paint.

Experimentation/Learning Objectives

•To study the effect of various system parameters like, solvent temperature, solvent rate and particle size on the %age recovery of oil from solid.

Utilities Required

•Electricity Supply: Single Phase, 220 V AC, 50 Hz, 5-15 Amp combined socket with earth connection. Earth voltage should be less than 5 volts.

•Water supply & drain

•Floor are required: 2.0 m x 1.0 m

•Solvent : 30 ltrs.

•Solid : 10 kg.
