Cooling Water Outlet Temperature: Evaluating The Best Maximum Value

By A. Durand, Nat. Univ. of Mexico ; R. Suárez, PEMEX; F. J. Román and A. S.  Cornejo,  IMP; L. Vazquez de la Parra, KAUST |

Corrections: From the October 2012 Letters page: This original article, which appeared in the print edition of Chemical Engineering (September 2012), had two errors: Equation (19) should read D = log (TH)-0.4, and Table 2 was missing decimal points in all numbers on both the x- and y-axes. The corrections are shown here. Recirculating cooling-water systems are essential parts of many facilities throughout the chemical process industries (CPI), including petroleum refineries, petrochemical, chemical and nuclear plants, and others. The cooling system shown in Figure 1 is widely used as a safe method for removing heat from various process operations.  Figure 1. The components of a typical recirculating-cooling-water system are shown here with the various inlet and outlet streams labeled Typically, the process engineer uses rules of thumb to define the cooling water flowrate, the temperature of the cooling-water return stream to the tower (t2) and the inlet temperature of the cooling water stream to the heat exchanger ( t1) [1]. These criteria can be used to obtain quick and reliable estimates, and to optimize both system design and operation. The temperature of the cooling-water return stream to the tower…
