CHECK INTO SEVERAL CHANGES

摘要

Here are a couple of suggestions that may help improve condenser performance until you can shutdown: 1. For a fixed UA, raising the column pressure increases the logarithmic mean temperature differential (LMTD) for the condenser and improves the ability to condense. Make sure your reboiler has some margin for over-design because at a higher column pressure the re-boiler will become stressed due to an LMTD pinch.
