Process Design

Reaction systems are designed and manufactured based on the users' needs such as studying a reaction kinetics at laboratory and pilot scale, catalyst screening or development. We offer TRL-RXN systems as it will provide best solution to your applications.

TRL-RXN systems consist of four main units such as upstream conditioning, reaction/sorption, downstream conditioning and analysis.

Plug Flow Reactor and Continuous Stirred Tank Reactor in our portfolio and these are for student laboratories in chemical engineering departments of colleges and universities.

PFR systems are designed to monitor a liquid phase reaction taking place in tubular reactor. Maximum versatility, ease of use. Operator adjustable reactor temperature. Operator adjustable reactant flow rate and concentration are basic features. All wetted parts are either PTFE or SS316.

TRL-CSTR system is designed to monitor a liquid phase reaction taking place in a stirred tank. Maximum versatility ease of use operator adjustable reaction temperature and reactant flow rates are the basic features. Wetted parts are PTFE and pyrex glass.

Wide Range Of Applications

Catalysis Research/Development

We offer reaction systems that can be designed for your catalyst research applications such as catalyst screening and development, catalytic activity and selectivity testing, TPD,TPR, TPO, TPRxn experiments, that requires control of flow rate, temperature, pressure, upstream conditions, for both heterogenous and homogenous catalyst types.

Sorption Studies

Parameters such as temperature, pressure, gas concentrations are very important in sorption studies such as sorbent material development, hydrogen sorption, CO2 sequestration. We can design and manufacture sorption systems based on years of experience.

Example of a custom designed catalyst screening test system that contains software controlled conditioning units for up and down stream, two zone temperature contolled reactor, which can be adjusted both vertical and horizontal, and gas analysis unit


Example of a downstream conditioning unit including rate, moisture indicator, halogen scrubber, mist trap, L/V separation and membrane drying equipment

Reaction Kinetics

Our reaction systems can be the best solution for applications related to reaction kineticts that are linked to the parameters such as temperature, concentration of reactants, flow rate of reactants and reactor type.
