Autoclaves (High-Pressure Reactors)

Autoclaves are sealed reactor vessels designed for batch processing under elevated temperatures and pressures. They provide controlled reaction environments for the treatment of liquid and solid materials, particularly in processes requiring hydrothermal conditions, dissolution, or chemical conversion.

At InVerTec, we operate high-pressure reactor systems for laboratory investigations, process development, and pilot-scale studies. Our reactor capacities range from 125 mL to 500 L, enabling experimental investigations at different scales and supporting the development of industrial processes.

Key capabilities

• Flexible reactor capacities from 125 mL to 500 L (laboratory to pilot scale)
• Demonstrated operation up to 250 °C and pressures of ~50 bar
• Mechanical agitation for homogeneous heat and mass transfer
• Controlled heating, cooling, and reaction time profiles
• Corrosion-resistant alloys and PTFE-lined reactor configurations
• Continuous monitoring of temperature, pressure, agitation, and pH

Technical Focus

• Temperature & Pressure Control: Demonstrated operation at temperatures up to 250 °C and pressures of approximately 50 bar.
• Mechanical Agitation: Controlled mixing to improve heat and mass transfer and promote homogeneous reaction conditions.
• Heating & Cooling Systems: Controlled temperature profiles for batch processing and hydrothermal treatment.
• Adjustable Operating Conditions: Flexible reaction times, heating profiles, and operating parameters to investigate process performance.

Achievements

• Flexible Reactor Capacities: Reactor volumes of 125 mL, 1 L, 60 L, and 500 L for laboratory and pilot-scale investigations.
• Material Compatibility: Different reactor configurations and construction materials, including corrosion-resistant alloys and PTFE-lined systems.
• Process Monitoring: Continuous measurement of temperature, pressure, agitation, and pH throughout experimental operation.
