petroleum fraction

18,000 lb/h of a petroleum fraction are to be cooled from 250°F to 150°F using cooling water with a range of 85–120°F. Properties of the petroleum fraction may be assumed constant at the following values:

A shell-and-tube heat exchanger with the following configuration is available:

Type: AES                                    Tubes: 3/4 in. OD, 16 BWG, 20 ft long

Shell ID: 15.25 in.                       Number of tubes: 128

Baffle type:                                  segmental Number of tube passes: 4

Baffle cut:                                    20% Tube pitch: 1.0 in. (square)

Number of baffles:                     50 Sealing strips: 1 pair

Shell material:                             carbon steel Tube material: Admirality brass (k = 64 Btu/h · ft · °F)

Fouling factors of 0.001 and 0.002 h · ft2 · °F/Btu are required for the cooling water and petroleum fraction, respectively. Is the heat exchanger thermally suitable for this service?
