Transcribed Image Text:Problem 4
You have developed a genetically engineered strain of a methanotroph bacteria (a bacteria that feeds
on methane) that produces formaldehyde, a compound used in a variety of medical applications, and for
the storage and preservation of biological tissue samples. The two main metabolic reactions involving
methane (relevant enzymes not shown) are:
CH4O2HCHO H20
CH4 202 CO2 2H20
You cultivate these bacteria in a bioreactor by feeding 100 mol/s of a 50 mol% methane, 50mol% oxygen
stream, and recover the produced formaldehyde from the effluent.
on extents of reaction to
a) Draw and label a flowchart of the process. Use a DOF analysis ba
determine how many process variable values must be specified for the remaining variables to be
calculated
b) Derive expressions (equations) for the product stream flow rates in terms of extents of
reactions
c) If the fractional conversion of methane is 0.9 (i.e. 90% of the incoming methane is consumed),
and the fractional yield of formaldehyde is 0.855 (i.e. 85.5% of methane entering the system is
converted to formaldehyde), calculate the molar composition (mol fraction of each component)
of the reactor output stream.
