Feed Conditioning

The feed is introduced into the column where the temperature and composition roughly match the column profile. The feed is at higher pressure in order to flow into the column. The location of the feed stream can be optimized with a few judicious choices with a process simulator. The feed quality and location can also be adjusted within limits to lower the reboiler or the condenser duty, but not both. The best opportunities for utilizing feed exchangers are during revamps when there is excess vapour- and liquid-handling capacity in one section of a column. For example, if the trays above the feed can handle more fluid traffic without modification, but the bottom section trays are capacity-limited, then installing a feed pre-heater can be used to unload the bottom traffic. The energy penalty will be increased condenser duty, but internal modifications or tower replacement may be avoided.
