Product Description

Pilot scale batch distillation column built to industrial practice, for separating a mixture whose components boil at different temperatures. The charge is heated in the reboiler; repeated condensation and re-evaporation up the column enriches the vapour in the more volatile component, and the packing increases the exchange area and so the mass transfer. Vapour is condensed at the column head and split between distillate and reflux through a globe valve, while residue is drawn off at the end of the run. Temperatures are read at the bottom, the middle and the head of the column, giving the full temperature profile.

Batch Distillation — specification

We manufacture the Batch Distillation in Ambala Cantt for chemical engineering teaching and testing laboratories, and supply it worldwide against institutional and tender orders. See the full Chemical Engineering Lab Equipments range.

Teaching objectives

  • Study of column hydrodynamics
  • Influence of operating conditions on the separation of a solution
  • Heat balance and mass balance calculations
  • Number of theoretical plates by the McCabe-Thiele and Ponchon-Savarit methods
  • Number of transfer units

Equipment

  • Borosilicate glass boiler with electric heating, low level safety switch and high temperature safety switch
  • Borosilicate glass column in two pieces with MULTIKNIT type packing in AISI 316L stainless steel
  • Two AISI 316L stainless steel plates, each with a sampling valve and temperature plug
  • Borosilicate glass column head with temperature plug and a solenoid timer valve controlling the reflux rate
  • Vertical condenser with borosilicate glass body and AISI 316L stainless steel exchanger, single effect with baffles
  • AISI 316L stainless steel distillate cooler
  • Two borosilicate glass distillate receivers, each with an AISI 316L stainless steel drain valve
  • Two polyethylene distillate collection tanks
  • AISI 316L stainless steel process pipework and reinforced PVC tubing for the cooling fluid
  • Support framework in AISI 304L stainless steel tube with aluminium connecting nuts and adjustable feet
  • Coolant tapping for pressure drop measurement
  • Flow switch on the condenser cooling water for operator safety
  • Level and temperature switches protecting the heating element
  • Variable reflux column head controlled by an ATEX solenoid valve

Instrumentation

  • Condenser cooling water feed with variable area flowmeter, adjusting valve and flow switch that cuts the heating if cooling water is lost
  • Column pressure drop by differential U-tube manometer
  • Command and control cabinet with emergency stop and operating buttons, housing an electronic timer for the column head valve, the boiler heating controller, and two digital temperature indicators reading seven Pt100 Ohm probes
