Topic: Re: How can I prevent vapor from moving to the outlet piping of condenser?

posed by 
If the condenser is connected at both inlet and exit, to a reactor generating vapors then you cannot prevent vapor bypassing the condenser without a seal leg.  There must be a liquid seal between the discharge of the condenser and the return line to the vessel, or the condensate must be collected in a separate vessel and pumped back to the reactor.
