PPR Parallel Pressure Reactor

Parallel Pressure Reactor system – PPR

Reactor volume: 50 ml – 300 ml
Number of Reactors: 2 – 6
Pressure: -1.0 (FV) to +100 bar
Temperature: -20 °C to +300 °C
Material: stainless steel / Hastelloy / Tantalum / PTFE inliner

Catalyst screening and Hydrogenations in reduced time, reproducible and safe: These were the key issues for our customer in chemical research, asking us to develop this system.

As a new Buchi product, this system needed to be configurable and modular to serve the different needs of our customers worldwide.

Modular Hardware:

2 – 6 Reactors PPR systems are available
Individual or parallel operation settings for each reactor (temperature, other)
Configurable hardware: from Basic to complete setup including dosing
Automated sampling

Operation modes:

Manual: The software controls the reactor hardware, data logging of process data
Automated: Low to high degree (full process automation including dosing of gas, liquids)
For full automation, a recipe editor is included in the software to edit existing settings and to define completely new processes.

Multiple safety features guarantee safe hydrogenations and other processes

Hardware – Pressure Reactors

2- 6 pressurized reaction vessels in its individual heating / cooling blocks can be controlled in the PPR system. The system is expandable, starting at 2 reactors.

Reactor block with individual heating / cooling
Lift for Reactor block lifting / lowering
Individual temperature control
Reactor with safety fast action closure
Stirrer drive with powerful magnetic coupling (75 Ncm torque)
Continuous adjustable agitator speed, 0-2500 rpm
Safety rupture disc
Pt100 sensor
Cover with 6 opening (for Pt100, dip tube, valves, etc.)
Optional burette, catalyst basket, gassing stirrer, others..
Optional liquid dosing via balance (at up to 275 bar)
Optional liquid dosing, SS316 pr PEEK corrosion resistant metering pump, flow rates 0.003 to 40 ml/min

Software – Process setting & control

The PPR software is user-friendly. Every single process step can be followed on the graphic display. It is GxP compliant, data can be exported. Multiple safety features guarantee safe process procedures. Operation mode can be chosen from manually to fully automated, depending on installed hardware.

Control parameters are: Reaction pressure / temperature, gas / liquid flow, gas consumption, stirrer speed, safety limits..

Available single automation steps:
