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, ¾ in OD, BWG 14, 12A 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? (i.e., what is the allowable fouling factor?)
HW Linde process is used for air liquefaction. The high-pressure gas leaving the compressor is at 120 bar and is cooled to 306 K (516 kJ/kg) before it is sent through the heat exchanger where it exchanges heat with low pressure gas leaving the separator at 2 bar. A 14 K approach is desired at the hot end of the exchanger so that the low-pressure gas leaving the exchanger is at 292 K (526 kJ/kg). Enthalpy of saturated liquid and saturated vapour at 2 bar are 121 kJ/kg and 314 kJ/kg, respectively. Determine: (a) The fraction of the air liquefied during expansion. (b) Temperature of the air on the high-pressure side of the throttle valve.
Steam with 80% quality is being used to heat a 40% total solids tomato puree as it flows through a steam injection heater at a rate of 400 kg/hr. The steam is generated at 169.06 kPa and is flowing to the heater at a rate of 50 kg/hr. Assume that the heat exchanger efficiency is 80%. If the specific heat of the product is 3.2 kJ/kg. K, determine the temperature of the product leaving the heater when the initial temperature is 50°C. Determine the total solids content of the product after heating. Assume the specific heat of the puree is not influenced by the heating process.
