Product Description

Absorption Desorption

Absorption Desorption trainer allows studying the absorption and desorption by analyzing the various variables affecting the process:  

  1. Liquid inflow
  2. Gas inflow
  3. Gas flow and liquid ratio.

Technical Features of Absorption Desorption

The main element of the Absorption Desorption trainer is a column of 1400 mm. height and 80 mm in diameter made in glass. The column is supplied filled with glass Rasching rings 9x9 mm, and also supplied with polypropylene Pall rings, for the replacement of the glass Rasching rings in order to be able to study the effect of the filler on the efficiency of the absorption and desorption process.  In both cases, the column filling maximizes the gas liquid contact surface, so that it produces the maximum possible absorption or desorption. The plant has pressure taps at the bottom and at the top of the column and two intermediate taps, through quick couplings connected to a water column differential manometer that allows determining the pressure drop within the column and the effects of the speeds of the liquid and of the gas on the pressure drop within the column.

The Absorption Desorption plant also has three intermediate samplers for sampling both the liquid phase and the gas phase and 4 temperature probes with digital display. The liquid phase is stored in a tank of about 30 liters of capacity made of polyethylene. Water or absorption liquid is led into the reaction column through a metering pump, which allows setting the incoming water flow to the column. In a flow meter positioned on the liquid inlet line can be displayed the liquid inflow. This flow meter is made of borosilicate glass and stainless steel with stainless steel float. The liquid is introduced through the top of the column through liquid diffuser, which permits the dispersion of the liquid and thus a better distribution of the fluid within the column.

Training Objectives of Absorption Desorption

The Absorption Desorption equipment is supplied with appropriate operation and maintenance manuals, including technical documentation of all equipment, and manual of the possible experiments such as:

  1. Effect of the speed of the absorbent in the absorption process,
  2. Effect of the air flow in the absorption process,
  3. Effect of the CO2 concentration in the absorption process,
  4. Effect of the height of the filling,
  5. Effect of the type of filling,
  6. Determination of the variables that affect the pressure drop,
  7. Effect of the speed of the liquid in the desorption process,
  8. Effect of the air flow in the desorption process,
  9. Effect of the ammonia concentration in the desorption process.
