Question Paper

Paper II
Section A
1. Answer any four of the following:
a. Define theoretical amount of air and excess air supplied for combustion of coal and sulphur
b. Define heat of reaction. How do you calculate heat of reaction at a given temperature and pressure
c. What are the ideal reactors? Emphasise the assumptions involved in defining the same
d. The entropy of the universe is ever increasing. Discuss
e. How do you analyse kinetic data collected in ad experimental batch reactor finally to arrive at the rate equation for the given reaction
2. A fuel gas containing CO2: C25H42: CO: 33.8%, H2: 40.6%, C12H44: 11.2% and N2: 5.3% is burnt with 30% excess air. Calculate the fuel gas (burner outlet gas) analysis on dry basis. Assume complete combustion in the burner
3. For the catalytic dehydrogenation of 1-butene (C4H8) to 3-butadiene (C4H6) C4H8 → C4H6 H2 carried out at 900 K and 1 atm, and with a ratio of 10 mol of steam per mol of butene, determine the extent of reaction at equilibrium. Determine the same in absence of the steam too
4. In an experimental catalytic packed-bed reactor, using a fixed feed rate of FA0 10kg-mol/hr, for the reaction A → the following kinetic data were collected Find the rate equation

Section B

c. What are the permissible limits of the constituents in the ambient air for residential and protected areas in India
d. Write short notes on: HAZOP/HAZAN studies
e. What factors you take into consideration in determining a chemical plant layout
2. How is paper produced commercially? Describe paper production from the raw materials, with the help of a neat flow sheet
3. Answer the following:
a. What is greenhouse effect? Discuss how various greenhouse gases contribute to the effect. What are your suggestions to minimize the greenhouse effect
b. How do ground level concentration of pollutant emitted from a chimney vary with meteorological conditions
4. Answer the following:
a. Define fixed capital and working capital. How do you arrive at them
b. Discuss briefly the utility of PERT/CPM charts
