Design a shell and tube exchanger for the following duty.
20,000 kg/h of kerosene (42° API) leaves the base of a kerosene side-stripping column at 200 °C and is to be cooled to 90 °C by exchange with 70,000 kg/h light crude oil (34° API) coming from storage at 40 °C. The kerosene enters the exchanger at a pressure of 5 bar and the crude oil at 6.5 bar. 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/m2 °C)-1 on the crude stream and 0.0002 (W/m2 °C)-1 on the kerosene stream.

What is a Recycle reactor?In some reaction system, it is advantageous to divide the product stream and a partreturned to reactor as recycle to increase the conversion rate. These reactors are calledrecycle reactors.
Calculate the heat (kJ) required to raise the gas temperature from 25°C to 1000°C if the heating takes place at constant volume (i.e., if the piston does not move), retaining successively one term, two terms, and all three terms of the heat capaci..

2. Alcohol is a diuretic agent, which increases urine production by reducing water reabsorption. Normal rate of water reabsorption is about 124 ml/min. Assume that the effect of alcohol on water reabsorption (in ml/min) is given by the following equa..
A fermentation reactor is charged with a sterile feed of growth media at 35 °C and inoculated with a batch of microorganisms. The batch is allowed to grow for 10 days. During the growth period the temperature is maintained at 37 °C by circulating ..
A preliminary (Class 4) estimate of the ISBL capital cost of building a 200,000 ton per year ethanol plant by corn dry milling has been stated as $130 MM -30%/+50%.
Determine the drying time for the constant rate period in hours - The drying time for the falling rate period in hours.
The length of the pipe line =305 m. The efficiency of the pump is 40 % and includes the losses at the entrance and exit of the pump. if the flow rate of the water is to be maintained at 3.15*10^-3 m3/s. and the water temperature at 16 oc . ,estima..
A rectangular loop is placed in the field of an in- finitely long straight conductor carrying a current of I amperes, as shown in Figure P12.1.2. Find an expression for the total flux linking the loop, assuming a medium of permeability µ.
Are the values of ak from part (c) what you would expect for this signal? Justify your answer clearly. (f) Suppose you wish to model the signal now with p = 3. Write the normal equations for this case.
In the manufacture of methyl ethyl ketone from butanol, the product is separated from unreacted butanol by distillation. The feed to the column consists of a mixture of 0.90 mol fraction MEK, 0.10 mol fraction 2-butanol, with a trace of trichloroe..
