SIM 3200 Condenser

Model Description

Our Condenser Simulation shows the typical arrangement found in the reflux section of a column. The gas process passes through a kettle type cooler first and then collected in a condensation vessel or reflux drum.

The process fluid contains many light hydrocarbons so is passed through tubes cooled by a constant supply of liquid propane. In order to maintain the temperature of the propane the pressure of the boil off gas is controlled by varying the outlet flow of gas. A constant supply of propane is provided by using a level controller to maintain the level of propane in the vessel.

After that, the multiphase process fluid is transferred to a different vessel so that any liquid contained in the flow may be separated from the gas. This vessel has level control for the condensed liquid and pressure control for the gas phase.
