Answer to Question #264877 in Chemical Engineering for maina

Question

Hydrogen can be produced using a process called coal gasification. It is desired to supply nearly pure oxygen to this process. Oxygen is separated from nitrogen out of the air (79 mol% nitrogen and 21 mol% oxygen) via a process known as cryogenic distillation. A cryogenic distillation unit has a feed of 2000 kgmol/hr air. The top stream has 1400 kgmol/hr nitrogen and the bottom stream has 320 kgmol/hr oxygen. a. Draw and label the flowchart of the process in block diagram. b. Write balances on the oxygen and nitrogen to determine the unknown component molar flow rates.

Answer 1

This converts the coal or biomass into gaseous components—a process called gasification. The resulting synthesis gas contains hydrogen and carbon monoxide, which is reacted with steam to separate the hydrogen. Fermentation: Biomass is converted into sugar-rich feedstocks that can be fermented to produce hydrogen .hydrogen is supplied almost entirely from fossil fuels, with more than 70% generated from natural gas and around 27% generated from coal.
