1. If all of the sulfur in the coal reacts to form H2S1 determine the air requirements for the Claus plant in kmol and standard m3 per kg of coal fed to the process.
2. Estimate the temperature to which the CO-H2 stream must be cooled to condense of the inlet CO, assuming ideal gas behavior and that CO is the only condensable component in the system. (The dependence of the vapor pressure of CO on temperature is given in Table 3-7 of Perris Chemical Engineer? liandhook.41 Determine how well the assumption of ideal gas behavior is satisfied by using the temperature calculated the first part of this question and the system pressure to estimate a compressibility factor for the product gas from the condenser using Kay's rule.
3. Determine the standard heats of Reactions. Discuss the purpose of feeding oxygen to the reactor.
4. Assuming no heat is lost to the surroundings, estimate the temperature of the gas and slag leaving the gasifier. (Hint: Choose the elements at 250C and 1 atm as reference states, and estimate Ht of coal from the higher heating value obtained using the Dulong formula)
5. At what rate (kW) is heat transferred to or from (state which) the methanol synthesis reactor to maintain its operation at 200°C You may assume that the recycle stream is at 40°C, and the fresh feed is at - 20°C.
