Low temperature and cryogenic condensation is a process that can be used as an effective means for VOC emissions control.
Cryogenic condensation technology is based on lowering the vapor pressure of a component by reducing the temperature of the process stream thus increasing the recovery of the components in the liquid or solid phase.
Nitrogen gas is widely used in the process industry. It is inert and typically transported and stored in its liquid state at low temperature and high pressure.
It is a convenient media to use. The low temperature cooling capability of liquid nitrogen allows for the design of highly efficient condensation systems.
Why wasting “ cold energy “ to the environment to vaporize liquid nitrogen and not use it profitably?
- Cryogenic condensation is well suited for VOC emission control because of its ability to respond instantly to changes in VOC flow rate and solvent loading.
- It can recover virtually any VOC species even under varying conditions.
- Cryogenic condensation can deal with all organics (even in the presence of water) and can function when the concentration and composition are changing over time.
- This flexibility makes it particularly suitable for VOC control in multi-product, multi-purpose plants where batch or continuous processes are employed.
