1. A constant-volume tank consists of a mixture of 120 grams of methane (CH4) gas and 600 grams of O2 at 25 degrees C and 200 kPa. The contents of the tank are now ignited, and the methane gas burns completely.
If the final temperature is 1200K, determine (a) the final pressure in the tank, (b) the dry analysis of the product stream and (c) the heat transfer during the process. Please note that no nitrogen participates in this reaction.
2. Determine the highest possible temperature that can be obtained when liquid octane (C8H18) at 25 degrees C is burned steadily with air at 25 degrees C.
A 30 mol% feed of benzene in toluene is to be distilled in a batch operation. A product having an average composition of 45 mol% benzene is to be produced. Calculate the amount of residue, assuming α = 2.5 and W0 = 100.
Plot the system curve on the pump characteristic given in Figure and determine the operating point and pump efficiency. Properties of the fluid: density 900 kg/m3, viscosity 1.36 mN m-2 s.
Develop a process schematic. Assume that this process is continuous. Show each product stream illustrating the impurity level with respect to the feed entering the particular separator.
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..

Under the mannich reaction, after the initial amine-formaldehyde reaction, could xylene act as a substrate to stabilize the reaction if the reaction does not stabilize during or prior to dehydration and clearing? In synthetic chemistry, amine-form..
A mixture of acetone and isopropanol containing 50 mol% acetone is to be distilled continuously to produce an overhead product containing 80 mol% acetone and a bottoms containing 25 mol% acetone. If a saturated-liquid feed is employed, if the colu..
Test the knowledge and understanding of the concepts and procedures for process instrumentation and communication systems used in process industries.
A liquid mixture consisting of 100 kmol of 60 mol% benzene, 25 mol% toluene, and 15 mol% o-xylene is flashed at 1 atm and 100°C. (a) Compute the amounts of liquid and vapor products and their composition.
questiona personal protective equipment are only used when it has proven impractical to control occupational hazards by
Ethane (C2H6) can be dehydrogenated to ethylene (C2H4), which can be dehydrogenated further to acetylene (C2H2). A reactor is fed with ethane and steam at a 1:1 mole ratio (The steam simply acts as a diluent). If the reactor runs at 1 atm and the rea..
A 1 m^3 isolated chamber with rigid walls is divided into two compartments of equal volume. The partition permits transfer of heat. One side contains a nonideal gas at 5 MPa and 300 K and the other side contains a perfect vacuum. The partition is rup..
