ABSTRACT:
Volatile vapors are removed from a storage vessel by establishing a flow of a stream of volatile vapors from the storage vessel and directing the stream through a first low temperature condenser for condensing a portion of the stream flowing through the first low temperature condenser. Since a portion of the condensed condensate freezes and causes a pressure drop in the first low temperature condenser, further steps may include directing the stream from the first low temperature condenser through a second low temperature condenser after the pressure drop exceeds a setpoint, stopping the flow of the refrigerant through the first low temperature condenser and using the heat of the volatile vapor stream to melt the frozen condensate in the first low temperature condenser. The stream is switched between the condensers as necessary to prevent excessive plugging due to frozen condensate formation. The system includes the means for implementing the method.
