Solid and Liquid Extraction Unit

Solid and Liquid Extraction Unit  ETSE-81

Contaminants may be present sorbed in the solid particles of the soil. Solid-liquid extraction allows these contaminants to be removed from the soil. Depending on the contaminant and the type of soil, a suitable solvent needs to be selected for this process. One field of application for example, is the separation of organic contaminants that are present sorbed in fine solid particles. Solid-liquid extraction may take place after these fine particles have been separated by a hydrocyclone in the ex-situ treatment of contaminated soil. The fundamental principle of solid-liquid extraction can be learned with The temperature of the solvent can be adjusted. Thus, it is possible to investigate the effect of this parameter on the separation process.

  • Extract outlet,
  • Extraction residue,
  • Extractant inflow,
  • Extraction material inflow,

Steam Distillation Setup

Steam Distillation Setup - ET-034A

The equipment consists of jacketed pressure vessel for distillation. Steam from a steam generator can either be allowed to enter in the outer jacket or in the vessel. The vapours form the top of the vessel are condensed in the shell and tube type condenser by circulating cooling water, supplied by laboratory overhead tank. The condensate is collected in a separating chamber. The set-up is fitted with steam trap, control valves, pressure gauge, temperature sensors and other instrumentations required. Steam distillation is used industrially to purify liquids, which are immiscible with water, and to remove bad odors from oils. When water is added to a high boiling liquid immiscible with it, the total pressure exerted by the mixture above the liquid surface will be the sum of the vapor pressures of the pure components and therefore the boiling point of the mixture will be less than that of water at the given temperature. Because of this, even high boiling liquids are made to boil at low temperature and their decomposition is avoided. The steam consumption for steam distillation process is normally high.

Experimentation

  • To study the characteristics of Steam Distillation.
  • Efficiency of simple steam distillation set-up.

Rotary Dryer

Rotary Dryer ETRD-79

The set up is designed to demonstrate and stimulate the moisture removal by heat under forced draft action created by hot air stream and shower of moist solid due to rotary action of dryer drum.The set-up consists of a long cylindrical shell slightly inclined towards the outlet rotating at low RPM. Counter current hot air from blower passes through heating chamber to produce hot air works as the drying agent entered from one side of the rotating shell and leave from other side removes the moisture from the moist solids. High moisture content feed enters from one end of the shell and low moisture content product discharges from the other end of shell. As the shell rotates internal flights lift the solids and shower them down through the interior of the shell. This action increases the contact of wet solid against hot-air making the dryer very effective.

An arrangement is made to vary and measure the airflow rate. A digital temperature controller is used to control and measure the temperature of air stream.

Hydraulic Ram Test Rig

Item code: ETE-2125 

Apparatus consists of a close circuit through which water is circulated continuously by means of a centrifugal pump of 25 mm x 25 mm with 0.5 H.P. motor to make the supply from sump tank. A
sump tank 125 cm long, 80 cm wide and 40 cm high
fabricated on M.S. angle frame with 3 mm thick M.S.
sheet is provided. Inside of the tank is lined with FRP. A
drain valve of 15 mm size is provided in the bottom of
the tank.
A supply tank 50 cm x 50 cm and 100 cm high fabricated
with S.S. sheet with over flow arrangement, gauge glass
tube and 15 mm size drain valve is provided. Inside of
the tank is lined with FRP. The tank has the provision for
fixing the supply pipe of 50 mm dia of which other end is
connected to the ram. The tank is supported on a stand
fabricated from M.S. angle.
For the supply head of 2.5 m, the discharge head of the
ram will be 15 m (approx.) the discharge will be 360 LPH.
A pressure gauge is provided with a regulating valve on
the delivery side of the ram (delivery pipe is of 15 mm dia) so that much greater head of water can be
observed and obtained by the adjustment of the shifting valve provided in the ram assembly. Lifted water
can be collected by the help of a collecting tank of 30 cm x 30 cm and 30 cm high. The tank is provided with
gauge glass tube, flow diverting arrangement and a drain valve of 25 mm size.
Waste water can be measured by the help of another collecting tank. The tank is provided with gauge glass
tube, flow diverting arrangement and a drain valve of 15 mm size.
Necessary G.I. piping system & flexible pipe of suitable size, necessary fitting and control valve are provided
with the apparatus.

EXPERIMENTS:

♦ To determine the efficiency of ram.

FEATURES:

♦ Compact & stand-alone set up
♦ Stainless Steel tanks and wetted parts
♦ Superb Painted structure
♦ Simple to operate & maintain
