Surface condensers usage

Utility Baiances. The operating company should also require a balance for each plant utility. The most involved of the utility balances is usually the supply/demand steam tabulation showing all levels of steam and condensate and their interactions. The steam balance is almost always required at this stage for any required side studies. The steam balance influences many design parameters, such as boiler size and contingency, treated water makeup rates, blow -down disposal rates, chemicals usage, and surface condenser size. 

Cooling water exit temperature > design and higher steam usage in distillation column rehoiler and uneven column operation excess condenser area via overdesign or clean surfaces.
