Cryogenic Plant Flow Sheet Overall: the Cryo process uses liquid nitrogen in a proprietary low temperature condenser to treat VOC laden emission streams effectively and reliably.

Pre-cooling:  the VOC gas stream is first pre-cooled with available cooling fluids or a mechanical-chiller to condense the bulk of the VOCs and moisture.

Energy recovery:  cold exhaust streams from the low temperature condenser are used to further pre-cool the incoming VOC gas stream.

Cryogenic condensation:  the flow rate of liquid nitrogen is regulated to control the temperature of the outgoing vent gas stream from the cryo condenser. The vent gas stream with VOC has cooled down to the desired temperature to help ensure compliance.

VOC recovery:  condensed VOCs pass through droplet separators and are collected in a tank to be pumped and reused.

Nitrogen recovery:  liquid nitrogen is fully vaporised in the process and exits the system as clean nitrogen gas to be reused for other applications.

Features & Benefits

  • Cryogenic condensation allows recovery above 99% of most VOCs
