Question
9. SOC high crude oil is to be heated from 15° C to 55° C at the rate of 1,50
ton/h using a stream from the plant. The crude oil is pumped in to the tube
and the heating stream is pumped into the shell side of an available heat
exchanger. The heating stream enters in to the tube at 150° C and leaves the
tube at 110° C. The average properties of both the fluids are given below.
The available heat exchanger (1-2 pass) has shell diameter of 23% in. The
shell has 324 tubes, ¾ in. OD, BWG 14 (wall thickness), 12 feet long arranged
on 1 in. Square pitch and supported by baffles with a 25% cut, spaced at 9 in
interval. You need to find the suitability of this exchanger for the purpose.
