50 L Multipurpose stailess steel reactor

PIGNAT — Wed, 06 Mar 2019 12:20:20 +0000

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.

Multipurpose automated rector 10L

PIGNAT — Wed, 06 Mar 2019 09:30:20 +0000

Multi-purpose automated reactor

The unit consists in one SS reactor, jacketed with heating and cooling area.

This design allows to heat, cool and maintain a set temperature.

Solid reagents are loaded through an accessible filling port on the cover.

One feeding funnel (filled under vacuum) is used to introduce liquid reagents inside the reactor.

A control valve allows accurate pouring of batch quantity of reagents or controlled pH based introduction.

During distillation, the reflux head is used to varie the reflux ratio from Zero to total reflux.

This ratio is set from the control panel (view on HMI).

The distillate is collected in 2 receiving funnels for which the filling is automated:

a level detection on the first one allows to detect if the capacity is full and to switch

to the second one.

The management of the first receiver is fully automated (filling, vacuum, draining etc…).

The second receiver is manual and used as a buffer.

Run the following operations

Liquid-liquid mixing or solid-liquid dissolution.

Evaporation, concentration.

Reaction, synthesis.

Distillation.

Decantation, crystallization.

Use a SCADA controlled unit

Run the process.

Control of parameters.

Record experimental data.

Create automated sequences

Introduction reactant.

Distillation according head temperature.

Cooling.

High level alarms management.

Automated draining during under vacuum process.
