FlexReactor®

FlexReactor Reactors – Customized and Modular®

Optimized Design for Temperature-Sensitive Reactions.

At ATHCO Engineering, we offer a comprehensive range of reactor design and optimization services to meet the needs of various chemical processes. The FlexReactor® is a next-generation, temperature-controlled reactor that combines customization, modularity, and efficiency. Designed for strongly exothermic or endothermic reactions, it delivers exceptional performance with features tailored to enhance reaction control and overall process efficiency.

Our Expertise in Reactor Design and Optimization

  • Transitioning from adiabatic to isothermal reactor designs for improved process control.
  • Comprehensive analysis of reaction processes, operating data, and catalyst data.
  • Advanced simulation and experimental calibration for precision engineering.
  • Fluid dynamics and heat transfer simulations for enhanced performance.
  • Innovative structural design and efficient catalyst handling solutions.

FlexReactor Design Overview

The FlexReactor® is engineered with a modular structure consisting of plate-to-bundle components enclosed in a pressure vessel. The catalyst is filled between paired plates, which circulate refrigerants or heat transfer media such as cooling water, saturated gas-water mixtures, or heat transfer oil. This unique design immerses the catalyst bed in the heat transfer medium, enabling precise reaction temperature control.

Advantages of the FlexReactor®

  • Rapid heat transfer with precise control of catalyst bed temperature.
  • Reduces hot spot temperatures, improving reaction selectivity.
  • Protects the catalyst from overheating and deactivation.


Simplified Design:

  • Eliminates the need for tubular sheets.


Catalyst Handling Made Easy:

  • High catalyst loading rate and efficient loading/unloading processes.


Compact and Flexible Structure:

  • Modular design allows easy installation and transport.
  • Small footprint, ideal for large-scale industrial reactors.


Customization and Versatility:

  • Tailored to specific reaction requirements with diverse structural options.


Energy Efficiency and Cost Savings:

  • Reduces the number of devices required, simplifying processes.
  • Optimizes heat recovery systems for energy savings and emissions reduction.
