Reactors

Chemical engineering refers especially to chemical reaction engineering.

Indeed, chemical reactions, catalyzed or not, are at the heart of all industrial syntheses.

Study of a chemical reaction, in a perfectly-stirred reactor, permits the operator to understand the influence

of the different parameters in the optimization of the chemical synthesis with a view to its industrialization.

 

Perform and study reactions

Esterification or saponification.

Concentration by evaporation.

Crystallization by cooling.

 

Knowledge of reaction’s characteristics

Basic, aqueous, organic, mineral medium.

Endo or exothermic reaction.

Bi-phase catalytic reaction.

 

Carrying out of an operation depending on operating conditions

Working pressure: atmospheric or vacuum.

Monitoring of cooling during crystallization.

Management of the distillation with reflux ratio definition.

Absorption and regeneration

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.

Continuous distillation water alcohol

This unit is design as a pilot scale plant. The column can be fed at several levels through the SS intermediate plates placed along the column.

The flow transmitters, the temperature sensors and the available pressure indicators, allow the user to monitor the processand

to study the influence of the different parameters and the operating conditions.

The DCS and the software application developed for this unit allow parameters variations,process automation and data acquisition in real time and/or historical (extra period).

 

Study of the transitional phases

Start the unit

Put equilibrium conditions

Stop the unit

 

Research of the optimum operating parameters

Feed rate, the preheating temperature, rate reflux, the pressure loss of column

 

Study of the adjustments of the parameter’s control
