Acetone is to be recovered from an aqueous waste stream by continuous distillation. The feed contains 10 mol% acetone. Acetone of at least 95 mol% purity is wanted, and the aqueous effluent must not contain more than 1 mol% acetone. The feed will be a saturated liquid. Estimate the number of ideal stages required.
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 ..
at atmospheric pressure ethyl acetate and ethyl alcohol form an azeotropic mixture containing 53.9 mole of ethyl
In the Deacon process for the manufacture of chlorine, HC1 and O2 react to form Cl2 and H20. Sufficient air (21 mole% 02, 79% N2) is fed to provide 35% excess oxygen and the fractional conversion of HCI is 85%.
Problem: A 500mm conductor inside an electric motor has a force of 1.5 newtons exerted on it. If it is at right angles to a magnetic field of flux density 0.6 T, calculate the current flowing in the conductor.
Calculate the rate of moisture condensation (kg/h) and the volumetric flow rate of the air drawn from the outside.
The heat capacity at constant pressure of hydrogen cyanide is given by the expression Cp[J/(mol ·°C)] = 35.3 + 0.0291T(°C) (a) Write an expression for the heat capacity at constant volume for HCN, assuming ideal gas behavior.
