Problem 1: Crude oil at the rate of 150,000 kg/h is to be heated from 20°C to 57 °C by heat exchange with the bottom product from a distillation unit. The product at 129,000 kg/h is to be cooled from 146°C to 107 °C. There is an available tubular exchanger with steel tubes with an inside shell diameter of 23.25 inches, having one pass on the shell side and two passes on the tube side. It has 324 tubes, % in OD, BWG 14, 12 ft long arranged on a 1-in square pitch and supported by baffles with a 25% cut, spaced at 9-in intervals. Is this heat exchanger suitable to achieve this heat transfer? CpJ/g.C H4, CP p. kg/m³ k. W/m-°C Product, outside tubes 2.20 5.2 867 0.119 Crude, inside tubes 1.99 2.9 825 0.137
