New Belgium Brewery has offered to donate spent grains from its operations to a CSU heating plant. As the heating plant engineer, your job is to evaluate whether it is feasible to use this material as fuel. Chemical analysis of the grains revealed the following composition: 14.4 wt% C 6.2 wt% H 78.8 wt% O 0.6 wt% S You placed 1.0 kg of the material into an evacuated lab reactor and heated it in the absence of air. When the batch was complete, the contents were returned to standard temperature and pressure (STP). At STP, an ideal gas occupies 22.4 L/mol. Only CO, CO₂, SO₂, and H₂O were detected in the exit gases, and no unburned material was left in the reactor. First, perform a DOF analysis for the process. While there are multiple ways, here treat the input stream (grains) as a mixture of different elements with known composition.
