Oct 11, 2005 · Hi,I want to size vertical condenser for methanol vapours above the batch reactor of 2 m3 volume. Reaction time is 1 hour, temperature is 50 C, and the pressure is 1 bar. Problem for me is to determine the quantity of methanol that evaporates in 1 hour. Thanks. Orion1.
The scenario in which SG tubes operate in a reflux condenser mode remains relevant to PWR mid-loop operation as well as a possible loss-of-coolant (LOCA) accident. In these modes, steam condensation in SG tubes provides a very efficient path for heat removal from the primary circuit of the nuclear reactor.

Parr offers two styles of condensers for attachment to the head of a stirred reactor or pressure vessel. These can be made in various sizes to match the size of the reactor. Reflux Condenser. The reflux condenser consists of a length of tubing connected directly to the head of a vessel and equipped with a water cooling jacket.
A reflux condenser is an apparatus commonly used in organic chemistry to prevent reactant or solvent loss in a heated chemical reaction. For chemical reactions that need to be carried out at elevated temperatures over long periods of time a reflux system can be used to prevent the loss of solvent through evaporation.
