Explain the graphical design procedure for finding the reactor size for adiabatic operations ofPlug flow and Mixed flow reactors.(May-2005 & Dec-2005) and The flowthrougha tubularreactor, inwhicha first order irreversible liquid phase reaction takes place, is increased by 20% and in order to maintain the same fractional conversion it isdecided to change the reactor operating conditions. The reaction has an activation energy of4kcal/mol and the initial temperature is 150oC. Find the new operating temperature of thereactor.(Dec-2004 & Dec-2005) and Discuss the stability criteria for exothermic reactions in Mixed flow reactors
The gases enter the condenser at 230 °C and leave at 50 °C. The cooling water enters the tubes at 20 °C and leaves at 50 °C. Suggest suitable materials of construction for the shell and the tubes.
Determine the minimum electric potential difference (in volts) that must be applied to accelerate an a-particle so that on interaction with a hydrogen atom, a ground state electron will be excited to n = 6
A recovery of 95% of particles greater than 100 μm is required. The minimum operating temperature will be 10 °C and the maximum 30 °C. Design a hydro cyclone system to handle 1200 liters/min of this slurry.
Elaborate on the hierarchy of control measures used in Industrial Hygiene How would you calculate the noise problem at the factory and what control measures would you consider before you recommend the supply of hearing protection to personnel ex..
Develop project plans for the design and construction of the following processes. Use Figure 1.2 as a guide to the activities that must occur. Estimate the overall time required from launching the project to the start of operation.
Design Options for Recovery of Acetic Acid from Aqueous Solution. The project involves the comparison of two methods for recovery of acetic acid from an aqueous solution. Your client is planning to add additional acetic acid production capacity of..
Need to make 250 ml of a 0.100 M solution of aluminum from a 5M stock of aluminum nitrate. What do you do?
A crystallization process requires operation at -5º C. The refrigeration system can reject heat to cooling water that is available at 35º C. If a single refrigeration cycle has an efficiency of 60% of Carnot cycle performance then estimate the cos..
For parts (a), (c), (d), (f), and (h) of Problem 10.20, determine the approximate percentages of the microconstituents that form. (a) Rapidly cool to 250(C (480(F), hold for 103 s, then quench to room temperature.
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..
Determine the minimum required numerical value of the dimension b of the posts in term of mm and
1. It is desired to use 28.32 m 3 /min of air (metered at a pressure of 101.3 kPa and 294.1 K) in a process. This amount of air which is at rest enters the fan suction at a pressure of 741.7 mm Hg and a temperature of 366.3 K and is discharged at a p..
