Reactor System

I Definition

The Reactor System refers to an integrated reaction vessel system containing equipment, having one or more reactors, that are assembled with one or several accessory facilities including lifting and flipping, distillation column, filter tank, feeding tank, condenser, receiving bucket, chiller, weighing and feeding, temperature controller, constant temperature tank, circulating pumps, booster pumps, etc.

II Characteristics

2.1 Structural features

The batch reactor is used in conjunction with various process control devices.
All the pieces of equipment are installed on a customized platform, which is closely distributed, occupies little space, with simple and beautiful structure.
Medium and large reactor systems are equipped with one or more intelligent controllers for perfect control of the reaction process.

2.2 Performance features

It is a further amplification of the function of the reactor.

2.2.1 Production type

Converts from batch to semi-batch, or continuous production.

2.2.2 Control mode

Converts from manual to semi-automatic or fully automatic control.

2.2.3 Safety Improvement

On-site operation can be converted to remote operation, real-time data monitoring, with more security.

2.2.4 Installation and maintenance

All equipments are purchased, made and installed by WHGCM, with unified standard, traceable equipment and low maintenance cost.

III Classification

3.1 Laboratory reaction systems

Used for batch reactions below 50 liters, generally for distillation, hydrogenation, esterification, polymerization reactions, etc.

3.2 Pilot reactor system

Containing one or more reactors, the function of the reactor is customized according to the requirements of the chemical process.
Generally installed on a special operating platform.
The production scale is generally in the range of 200 liters to 1000 liters per batch, or semi-intermittent or continuous reaction.
The reaction is relatively complex, with a large number of reaction materials.
There are many parameters to be controlled, some of which need to be programmed by PLC for precise control.

3.3 Tandem reactor system

This is a device for continuous reaction of reactants with three reactors of more than 1000 liters designed as a whole and controlled centrally.
The reactors are connected in series through piping. Its structure, configuration, and control system can be customized.
The reactors are mounted on a platform for easy operation.
Optional control system:
It is able to realize automatic control, data acquisition, and storage of temperature, gas flow, liquid flow, pressure, sampling time, and other parameters during the test.
With automatic sampling gas chromatography online analysis function.
It has the function of alarming the abnormal working state of the system and automatic risk evacuation.
In order to ensure the safe operation of the experiment, the device has over-temperature, over-pressure sound and light alarms, and can automatically cut off the power supply of the equipment and stop the relevant circuits.
The automatic control system has a process flow chart, control flow chart, parameter setting table, real-time curve, and historical curve of each control point, and supports online printing records.
