Plate gas-liquid phase temperature
Thread Content
Under normal circumstances, by how much is the temperature of the gas phase entering a tray higher than the temperature of the liquid phase leaving that tray?
Each tower is different; the temperature drop per tray in the design is basically fixed. In operation, factors such as the distribution ratio of heat uptake by various reflux streams and the magnitude of the load have an impact
In theoretical calculations, a plate is considered to be a constant-molar-flow, homogeneous system; however, in reality the situation depends on specific conditions. Under different systems and fluxes, as well as under various operating conditions, the actual temperature difference can vary significantly!
