A storage vessel (1 million L) contains Ethylene (C2H4) 20% vol., Propane (C3H8) 40% vol and Butane (C4H10) 40% vol. at a pressure of 250 Psig. 1) Calculate LFL and UFL for this mixture in pure oxygen and air. Calculate LOC for the mixture assuming that LOC MILE = {x,LOC, 2)Using the stoichiometric concentrations for each component (see below), calculate the value of "z" based on the combustion of CmHx + 2O2 = ...... Calculate UFL and LFL in air using m, x, and z values. Compare and contrast the results of section (1) and (2). 3) Construct the flammability diagram using the results of section (2) only. 4) Find the LFL and UFL in pure oxygen from the flammability diagram and compare and contrast with the results of section (1). Attention: you can make reasonable assumptions and justify. If you need additional data use available resources (handbooks, internet, etc). The references should be addressed in detail. C2H4 + 302 = 2 CO2 + 2 H2O C3H8 + 5 O2 = 3CO2 + 4H2O C4H10 + 6.5 O2 = 4CO2 + 5 H2O
