Hydrogen production calculation
Thread Content
Dear experts, my company plans to build a facility for producing hydrogen through the conversion of natural gas light hydrocarbons, with a capacity of 20,000 NM3/h. At present, I need to calculate the amount of raw materials required; however, my calculations yield very different results – I get 4.6 NM3 of hydrogen per unit of natural gas, which obviously cannot be correct, but I am unable to identify the error in my calculations. Could anyone among the experts provide me with the calculation formulas for hydrogen production? Thank you
Know the composition of natural gas, list the chemical reaction equations, including losses, OK
4.6 NM3 of hydrogen per unit of natural gas? What unit do you mean by unit?
Theoretically, 1 cubic meter of natural gas produces about 4 units of hydrogen; losses also need to be taken into account. In our case, the hydrogen production from natural gas is around 2.8 to 3 units per cubic meter
One molecule of methane produces 4 molecules of hydrogen; by subtracting the amount of hydrogen in the purge gas, we obtain the approximate hydrogen production amount. I estimate that your feed volume will be around 6,200
