Fuel cells can be powered by the reaction between formic acid and oxygen as following As formic acid and oxygen react together inside the fuel cell, it produced both electrical power and heat. While there is no shaft work produced by the fuel cells, this electrical power produced by the fuel cells can be considered as the shaft work term when you perform the energy balance. A fuel cell is being supplied with 100. liters per minute of pure formic acid at 1 atm and 25 °C. Air is also fed to the fuel cell to supply the oxygen. The air is fed at 1 atm and 25 °C and at 100% excess. The fuel cell operates at 70 °C so that the gas stream leaving the fuel cell is also at 70 °C. The gas stream leaving the fuel cell contains no formic acid. The fuel cell transfers heat to the surroundings at a rate of 1.50 x 103 kW.

Terephthalic acid (TPA) is synthesized from -xylene (PX) in the
process C8H10 +302 – C8H6O4 +2H2O shown below. A fresh feed of pure
liquid PX combines with a recycle stream containing PX and a
solution (S) of a catalyst (a cobalt salt) in a solvent (methanol).
The combined stream, which contains S and PX in a 3:1 mass ratio,
is fed to a reactor in which 90% of the PX is converted to TPA. A
stream of air at 25...

Hydrogen and oxygen gases are utilized as reactants for fuel cells. Hydrogen gas is oxid side to generate protons and electrons which move to the cathode side to react with oxygen to produce electricity and water as byproduct. Molecular weight: M(H2) -2 g/mol, M(O)-32 g/mol, M(H-0) - 18 g/mol. Detailed reactions in each side are described below: ized in the anode (-) side: | (+) side: Cell: H2 → 2H+ + 2e- E" 0.00V 202 + 2H+ + 2e-→ H2O...

1) In a batch culture, formic acid (HCOOH) is produced using bacteria. For each mole of glucose (C H206) utilized by the bacteria, 2.40 moles of cells (CH1.8000 1No.26), 1.70 moles of formic acid, 1.90 moles of gaseous CO2, and some H20 are formed. Oxygen (O2) and ammonia (NH3) were consumed. Glucose, ammonia and 18,350 kg of water were fed to the reactor and inoculated with the bacteria. Air is pumped into the reactor and during the entire process 6000...

A fuel gas containing 95 mole% methane and the balance ethane is burned completely with 25% excess air. The stack gas leaves the furnace at 900°C and is cooled to 450°C in a waste-heat boiler, a heat exchanger in which heat lost by cooling gases is used to produce steam from liquid water for heating, power generation, or process applications. (a) Taking as a basis of calculation 100 mol of the fuel gas fed to the furnace, calculate the amount...

The combustion of fuel in your car engine requires oxygen gas, which is supplied as air (21% oxygen molecules) into the engine. Consider a car that is using 100% ethanol, C2H5OH, as fuel. If your engine intakes 3.7L of air per minute at 1.00 atm and 25°C, what is the maximum volume of ethanol (0.789g/mL) that can be burned in one minute?

You are the design engineer for a natural gas co-generation power facility shown in the diagram below. You have been asked if the facility's exhaust gas can be fed to a greenhouse in order to grow plants without having to add a make up stream of air to cool it. This can be done if the temperature of the facility's exhaust gas is less than 130°F (54.4°C) In steady state, the Gas engine is fed a stream of natural gas...
