Answer #1

Once the concentration of acetone at the top and bottom of tower is estimated, it is converted to mass flow rate of the top and bottom tower of acetone. If the acetone recovered is of use only as the top product (since stripping is a process of removing the product of interest from a liquid (bottom) using vapor or gas (top), then the mass flow rate of acetone recovered = mass flow rate of acetone in top product = mass flow rate of acetone in feed - mass flow rate of acetone in bottoms.

By means of a plate column, acetone is absorbed from its mixture with air in a non-volatile absorption oil. The entering gas contains 20 mole percent acetone, and the entering oil is acetone-free. Of the acetone in the air, 98.5 percent is to be absorbed, and the concentration of the liquor at the bottom of the tower is to contain 8 mole percent acetone. The equilibrium relationship is ye=1.85xe. Plot the operating line and determine the minimum number of stages....

A tube is run from the bottom to the top of the Grand Canyon (a depth of 1800 m). If the pressure at the top is 1.0X105 Pascals and the pressure at the bottom is 1.1X105Pascals, what must the velocity of the fluid be at bottom if the velocity at the top is 2 m/s? How can the opening having a cross-sectional area of 0.5 m2 be adjusted to get water to come four times as fast?

A distillation column with a total condenser is separating acetone from ethanol. A distillate concentration of xD = 0.90 mole fraction acetone is desired. Since CMO is valid, L/V = constant. If L/V is equal to 0.8. The distillation column has a partial reboiler that acts as an equilibrium contact. If the bottoms composition is xB = 0.13 mole fraction acetone and the boilup ratio V/B= 1.0, find the vapor composition leaving the second stage above the partial reboiler. a)...

A 19.4-kg box is being pushed from the bottom to the top of a frictionless ramp. When the box is pushed at a constant velocity, the nonconservative pushing force does 58.0 J of work. How much work is done by the pushing force when the box starts from rest at the bottom and reaches the top of the same ramp with a speed of 1.50 m/s?
