Formaldehyde is a common preserative agent used in a wide variety of products ranging from pressed wood, cosmetics, embalming fluids and vaccines to list a few examples. It can be made by oxidizing (reacting) methane with air as shown below: CH4 (g) + O2 HCHO + H20 Calculate the components in the exit stream as well as the change in enthalpy for the system (i.e. determine Q). Assume that air is added in 50% excess and the reaction goes to 90% completion. 100 mol/h CH4 25C 150C Air Stream Components 100C To be determined QIN
