Photo-Flo Reactor

Amar has been a pioneer, largest manufacturer and exporter of continuous flow reactors in India since many years. Amar Flow Reactors are used by various industries like fine & speciality chemicals, bulk drug (API) pharmaceuticals, dyes, intermediates, paints, agrochemicals, etc. to convert their batch chemistries to continuous flow.

  • Volume: 12 ml to 200 ml volume reactors
  • Flow Rate: upto 150 lph
  • Pressure Range: up to 18 bar
  • Temperature Range: -20°C to 150°C
  • Material: PFA
  • Combines the advantages of continuous flow processing with the added benefits of ultraviolet light to enable photochemical reactions.
  • UV transparent chemically inert tubes.
  • Scale independent (capable of producing from few gm to kgs)

Working

Novel chemistries like photochemistry in flow are increasingly becoming an area of focus for both academia and industry owing to numerous advantages of adopting the flow chemistry route. As per Beer - Lambert Law, light intensity exponentially decreases with the length travelled in solution, which becomes a major challenge with scaling-up a photochemical process in batch. With Amar photochemical reactor, one can provide consistent light penetration on the solution, give precise residence times and temperature to increase the reaction rates and product selectivity dramatically.

Application

These reactors are ideal for carrying out a wide range of chemical reactions in the field of pharmaceuticals, fine and specialty chemicals in a continuous manner. These reactors are suitable for various applications such as photo chlorination, production of Vitamin D, Photo Alkylation, Artemisinin production, production of e- caprolactame, etc.

Accessories

Apart from our standard specifications we also provide additional value-added optional accessories to enhance the versatility and functionality of the equipment for various applications. Some of the components that we provide as a part of our flow reactor systems :

This system is used to charge liquid at a desired rate from as low as 1ml/hr, is under pressurized condition.

  • a) Diaphragm metering pumps for pressures up to 100bar & minimum flow range of 60-600ml/hr to maximum 10-100 lit/hr. The flow rates are varied by varying the motor speed with variable frequency drive. Materials: SS316, options: Hastelloy C, Titanium, PTFE.
  • b) High pressure more accurate HPLC type low flow metering pumps for high pressures up to 350 bar & flow range from 0.01 up to 100ml/min. Materials: SS316, option: Hastelloy C, Titanium.
  • c) Low/High pressure syringe, pumps can be offered for pumping corrosive chemicals.
  • Single Fluid closed loop system from -90°C to 250°C.
  • Heating Cooling bath circulators from 70°C to 175°C.
  • High temperature circulators from ambient to 350°C.
  • Chillers up to -15°C.
  • Suitable for reactor volume from 10 ml to 3000 ltr.

It is SS316 regulator mounted on the vent line of the reactor &is used for maintaining constant pressure inside the reactor up to 350bar. The pressure is maintained by releasing the excess pressure into the atmosphere.
Optional

  • a) Electronically actuated digital pneumatic back pressure regulator, where the pressure is set digitally & can be released at preset rate of pressure release (6bar air supply is required).
  • b) Pneumatically actuated pilot operated back pressure regulator (air/N2 gas supply for rated pressure is required to activate the same).
  • c) Electronic control unit & forward pressure regulator with 4mtr.
  • Materials: Hastelloy C, PTFE etc.

MFM can be used to measure accurate mass flow rate of gas (in gm/hr or LPH) & totalized quantity of mass/volume (in gm/ltr) charged in the reactor at any point. Mass flow controller (MFC) is used to charge the set flow rate of gas into the reactor at high pressures up to 100bar. The same MFM/MFC comes with high pressure flexible hose, inlet filter with digital gas flow indicator.

It consists of SS316 pressure sensor (transmitter) & digital pressure indicator/ controller (mounted on common control panel) with pressure alarm.

This unit is used to separate plug flow of two immiscible liquids used in biphasic reaction or two phases of an extraction flow.
MOC: ETFE, PFA & PTFE, pressure @ 300 psi.

Control Panel consists of programmable PID temperature controller cum indicator with temperature alarm system (settable), safety alarm & heater trip system for malfunctioning of controller/sensor/ temperature rise beyond set limit. Digital pressure indicator/ controller, gas/liquid flow indicator, totalizer, heater, level, pH etc. Indicators are provided additionally on same common control panel depending on the optional accessories are selected.
Optional :

  • a) Touch screen panel with SCADA software.
  • b) PLC based control panel with touch panel HMI or remote SCADA software & PC Control.
  • c) Complete Ex-proof-flame proof (FLP) group IIA/IIB or IIC, ATEX zone 1, class 1 div. 2 certified.

Note : All accessories may not be applicable for the selected model. For more details Contact US.
