详细介绍

● OTP pilots allows work on an industrial scale in various fields: chemical engineering, maintenance, supervision 

● Understand the continuous absorption process


Study of the transitional phases 

    Starting the unit 

    Put equilibrium conditions 

    Stop the unit 

Research of the optimum operating parameters  

    Feed rate, preheating temperature, reflux rate, column pressure losses 

Study of the effectiveness of the process  

    Mass balance, thermal balance, yield, productivity 

Study of the technologies implemented


General specifications 

Absorption:  

• SS gear pump. 

• SS heat exchanger (cooler). 

• Two section of glass column. Packing: Raschig rings in glass. 

• Cool exchanger line allows to cool the solvent.

Regeneration:  

• Two section of glass regeneration column. Packing: Rashig rings in glass. 

• Glass exchanger shell, SS tube, system reflux. 

• A SS heat Exchanger, with steam pneumatic control valve. 

• Thermosiphon reboiler with glass shell and a SS tube heat exchanger heated by steam.

Instrumentation 

• 12 temperature probes Pt100Ω. 

• 2 air mass flow transmitters. 

• 1 water cooling transmitter. 

• 3 flow transmitter ( supply, and low absorption and regeneration columns). 

• Differential pressure transmitter. 

• Rate control. 

• Absorption level transmitter. 

• Vapor/regeneration pressure transmitter. 

• 2 CO2 transmitter analyzers.


The solute migration phenomenon from the gas to the liquid phase occurs when both phases are contacted in the packing of the reverse flow absorption column. This highlights the absorption operation (solvent purification). 

The regeneration phenomenon is observed on the second column, which is continuously fed. 

An energy-saving heat exchanger is placed between the two columns to optimize the power spent on the unit. 

A second heat exchanger is placed on the absorption side to cool the fluid returning to the head of the column. 

The third heat exchanger, placed on the regeneration side, allows the solution to be heated in order to be regenerated in column 2. 

The use of such a unit allows one to remove CO2 from air using monoethanol amine and to recover pure CO2 to capture it.
