Lowering the Column Pressure

Reducing the column pressure also decreases the reboiler temperature and can favorably load the trays or packing as long as the column stays below the flood level. The overhead temperature, however, is also reduced, which may create a condensing problem. If the overhead stream is lost because of an undersized condenser, a company can consider retubing, replacing the condenser, or adding a supplementary vent condenser to minimize losses. The vent can also be rerouted back to the process if the process pressure is stable. If a refrigerated condenser is used, the tubes must be kept above 32°F if any moisture is in the stream.
