Design a Heat Exchanger for the Following Duty:

Reduced crude oil leaving a distillation unit with a flow rate of 3166.04 kL/d at 268 oC and is to be cooled to 243 oC by exchange with 62.8 kg/s pre-flashed crude oil coming from pre-flash unit at 206 oC. A pressure drop of 0.8 bar is permissible on both streams. Allowance should be made for fouling by including a fouling factor of 0.0003 (W/m2oC)-1on the reduced crude stream and 0.0002 (W/m2C)-1on the pre-flashed crude stream. Design and optimize a suitable shell-and-tube heat exchanger that can satisfy the above mentioned duty.

Hints:

  • Fix a tentative geometry and perform all standard calculations;
  • Verify the adequacy of your proposed design in terms of operating parameters; and
  • Modify the proposed design to make them compatible with the required allowances of parameters.
