Continuous Flow Microreactors

Continuous Flow Microreactors

000

Continuous flow reactors developed under AMaR series are designed to offer excellent mixing and heat transfer for carrying out fast and exothermic reactions. The design is based on extensive experiments as well as years of research on flow and transport processes carried out at CSIR-National Chemical Laboratory, Pune. The geometry is selected in a manner that while they offer high heat transfer area per unit reactor volume, they also allow flow of dilute suspension of nano-catalysts. The channels / tubes may also be packed with catalyst for catalytic reactions.

Features

  • Designed to offer excellent mixing and heat transfer for carrying out fast and exothermic reactions on continuous basis in microchannels
  • Pressures upto 50 bar
  • Flow rate upto 40 l/hr per plate
  • Modular design to connect upto 10 plates in series or parallel
  • Reduced waste and faster transfer of process from laboratory to pilot/commercial scale manufacturing

Advantages of continuous flow reactors over batch reactors:

  • Better mixing & very high heat transfer area per unit volume
  • Faster reactions & better selectivity.
  • Higher yield.
  • High safety & ideal for exothermic reactions.
  • Reduced waste and faster transfer of process from laboratory to pilot/commercial scale manufacturing
  • Easily scalable

Applications:

AMaR series is ideal for carrying out a wide range of chemical reactions in the field of pharmaceuticals, fine and specialty chemicals in a continuous manner.

Suitable for

  • Homogeneous reactions: Neutralization, condensation, dehydration, photochemical reactions etc.
  • Multiphase Reactions: Gas-liquid reactions (G-L): oxidation, ozonolysis, chlorination, etc. Liquid-liquid reactions (L-L): nitration, transfer hydrogenation, sulfoxidation, amination etc. G-L-S and L-S catalytic reactions: esterification, hydrogenation, condensation, etc.
