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.
Name the micro structural products of 4340 alloy steel specimens that are first completely transformed to austenite, then cooled to room temperature at the following rates:
Determine the values of the constants a and c and state the units and draw the path on a PV diagram also draw Path on the diagram and calculate the heat and work interchanges between the system and surroundings.
Consider a diatomic gas, N2, at 298 K. This gas is compressed reversibly and adiabatically from 15 dm3 to 5.0 dm3. Assume that the heat capacity of this gas is CV=5R/2, and that it behaves ideally. Calculate the final temperature, T2, of the gas.
Adsorption and Membrane Processes
Determine the maximum layer of the hydrogel membrane that would result in an oxygen concentration of at least 1.104 mol/mL everywhere in the capsule.
Carry out a sensitivity analysis on the adipic acid project described in Example 9.5. Investigate the sensitivity of the 10-year NPV to variation in total fixed capital (-20% to +50%), annual gross profit (-20% to +30%), and project construction s..
Write balanced equations for the combustion of each component of the fuel gas.
Calculate the work done in the isothermal reversible expansion of one mole of CH4 (g) from 1.00 dm3 to 10.00 dm3 at 300 K. Treat methane as a van der Waals gas. The van der Waals gas constants for methane are: a=2.3026 dm6⋅bar⋅mol−2 and b=0.043067 dm..
Choose an initial guess for reactor temperature and pressure within the range provided and simulate the process described - Determine a metric to quantify the reactor performance then use this parameter to optimize the reactor temperature and pressu..
A substance, A2B, has the composition by mass of 60% A and 40% B. What is the composition of AB2 by mass?
The mole fraction of ammonia in exit gas from the tower is 0.003. Assuming isothermal operation and considering the following equilibrium data calculate the height of the packed bed.
For an ideal gas (this is an assumption that can be made under certain conditions including low pressure and high volume in which it is assumed that the molecules in a system either do not touch OR their collisions are completely elastic), the pressu..
