PhotoFlowReactor
The amount of photons required for a photochemical reaction is stochiometric means proportional to the quantity of starting material reached by the radiation. Additional photons are required to compensate the loss due to the absorption while passing through the material of the lamp, the of reactor and fluids as e.g. the solvent. With flow reactors the pathway of the radiation through the fluid can be kept short and hence the absorption low so that they are more efficient than stirred reactors. The PhotoFlowReactor consists of a cylindrical immersion lamp installed in a cylindrical pipe generating an annular gap. The reaction fluid flows through this annular gap, a short pathway for the radiation. This basic design is common in lab scale. De Dietrich Process System has transferred this concept together with PESCHL Ultraviolet GmbH into this production scale PhotoFlowReactor.
The PhotoFlowReactor is a flow reactor for photochemical reactions in a liquid phase with the option to disperse a reaction gas at the inlet. The photoreactions can be carried out between -30 to +100°C at up to + 1 barg. The max. hydraulic flow rate is far above 20m³/h so that the maximum operational flow rate is determined by the min. residence time necessary for the reaction. The PhotoFlowReactor has been standardized for different directly illuminated reactor volumes up to 150l.
A continuous PhotoFlowReactor permits a much narrower residence time distribution than a continuous stirred reactor so that a higher selectivity can be realized.
PhotoFlowReactors can be connected in series to increase the residence time or in parallel to increase the throughput. As such they can be operated in full continuous mode or in batch mode as side loop reactors.
Compact Gas Scrubber
The highly corrosion resistant compact gas scrubber is especially advantageous for batch wise operated production plants with waste gas streams up to 200Nm³/h at atmospheric pressure.
Filled with a suitable absorption liquid it is suitable for gas streams containing acidic or caustic and also organic loads. The absorption heat can be withdrawn by a heat exchanger. The unit is therefore of universal usage.
The column of the gas scrubber with an effective height of 2m is split into 2 sections so that the total height of the complete system is also only 2m. The mobile unit requires therefore only a minimum room height and clearance to get it transferred in one piece to its operational location.
It must only be connected to the electrical power and cooling water supplies.
The turn-key unit incl. control panel is ready for operation in ex-rated areas. The measuring and control equipment indicate the process parameters and alarms, run the plant always into a safe state and permit hence the unattended operation.
