• Inconsistent batch performance due to high sensitivity towards process variables (temperature, pressure, concentration, time and mixing)

• Process needs- High heat transfer area- Efficient mixing- Rapid mass transfer- High interfacial area

• Safety issues in- Storing large inventories of hazardous reactants- Handling of hazardous and unstable chemicals- Generation of unstable species during the reaction- Containing unwanted runaway

• Process waste related issues- Need for enhancing the selectivity close to theoretical value- Generation of waste that needs treatment- Need to avoid or reduce the downstream processing efforts for purification

• Distributed production- Produce only as per the local requirement/ consumption (Location wise production)- Produce only as and when needed (avoid inventories)

• Optimal utilization of facility- A continuous flow manufacturing facility can also be used for production of multiple products with almost same

peripherals- Space occupancy will be less- Achieve same or even better than conventional batch operation

Transform your process development capabilities using AMaR series continuous flow reactors

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.

Applications

Suitable for

• Homogeneous reactions: Neutralization, condensation, dehydration reactions etc.

• Multiphase Reactions:

- Gas-liquid reactions (G-L): oxidation, ozonolysis, chlorination, etc.

- Liquid-liquid reactions (L-L): nitration, diazotization, azo coupling, transfer hydrogenation, sulfoxidation, amination, nitration of aromatic substrate, acylation, formylation, methylation, synthesis of nanomaterials, knoevenagel condensation, meerwein arylation, glycosylation reaction etc.

- G-L-S and L-S catalytic reactions: esterification, hydrogenation, condensation etc.

The devices 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.

Key design attributes

• 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 scaleable

Advantages of continuous flow reactors over batch reactors:

•

• Microchannels with modular system to connect multiple reactors in series or parallel

• Pressures up to 350 bar & temperatures up to 500°C

• Flow rates up to 500 LPH per unit

• MOC: SS316, Hastelloy, Inconel, Monel, Titanium, Tantalum lined, Gold plated etc.

• Suitable for various liquid-liquid, gas-liquid homogeneous - multiphase reactions, gas, solid & liquid catalytic reactions

Available in integrated multilayer & tubular metal construction for reaction & heat transfermixing,

Liquid-Liquid SeparatorThis unit is used to separate slug flow of two immiscible liquids used in biphasic reaction or two phases of an extraction flow. MOC: ETFE, PFA and PTFE, pressure 300 psi.

Wet Gas MeterWet gas meter is an analog instrument used to measure exhaust gas flow for gas mixer & is available in all flow rate ranges. It can give output for digital flow indication

Sample / Status / Steam Selector ValveThese valves have unique variety of connecting slots and ports arrangements. It allows multiple planes of ports, facilitating unique multiposition configurations useful for stream selection, column selection or trapping. Can be configured for use at temperatures up to 350°C or pressures up to 10,000 psi.

Oven / FurnaceThis can be used for various applications commonly where condensation is major issue during process. The complete assembly can be placed inside oven to avoid condensation or to maintain particular temperature throughout the process. Temperature rating: 200°C for oven & 500°C for furnace.
