HOF CryoProPhase - Cleaning and recovery of solvent-containing waste gases by means of cryogenic waste gas treatment flexibly customised to customer requirements
Together with our partner HOF Sonderanlagenbau GmbH, we have developed a special process for recovering solvents from the exhaust streams of freeze-drying systems. The system is specifically designed for applications in freeze-drying and enables the condensation and recycling of organic solvents used in specialized lyophilization processes – for example, ethanol or tert-butanol, as well as corresponding water-solvent mixtures. Recovery occurs from one or more typical exhaust streams of the freeze dryer and supports both compliance with regulatory requirements and the reduction of emissions and operating costs. For humid or variable exhaust compositions, the system can optionally be equipped with spec
The cooling is achieved without the use of liquid nitrogen and exclusively with natural refrigerants. The required low temperatures are generated by the cold air cooling system from Mirai Intex.ial regenerative heat exchangers and an integrated regeneration cycle to ensure stable and energy-efficient process operation.
In cryo-condensation, pollutants are condensed from the exhaust gas by cooling the exhaust gas line. The highly volatile components in the exhaust air flow are present as liquid condensate after the process and can either be fed back into the production process, purified or disposed of.
The cold air chiller from Mirai Intex enables large dynamic load changes with high efficiency thanks to the infinitely variable turbo compressor expander unit. The required process temperatures can be flexibly set between -40 °C and -160 °C via the cold air chiller. The optimum condensation temperature can therefore always be individually selected for different process conditions.
The CryoProPhase has a modular design, which allows the process to be designed flexibly and makes optimum use of installation space. For example, the process lines can be positioned decentrally, while the cooling is provided centrally by the cold air chillers.
Reliable, durable, efficient and safe for people and the environment!
Air as a refrigerant is always available and is free of regulations.
Flexible setting of the condensation temperature between -40 °C and -110 °C, optionally up to -160 °C.
Ambient air only as refrigerant. Operating pressures up to a maximum of 10 bar overpressure.
Oil and wear-free thanks to the air-bearing compressor-expander unit of the cold air chiller.
Flexible process control and installation possible thanks to modular design.
Through refrigeration close to the useful temperature, efficient cold air cooling technology and energy recovery.
High efficiency and compliance with limit values even under dynamic process conditions
Most of the exhaust gases can be fully recycled and reused
