Suppose a membrane separator, operating at 8 atm and 350 °F, is used to separate the H2 and CO2. Assuming the fluid behaves as an ideal gas, determine: SCFH going into the separator The true volumetric flow rate going into the separator The molar flow rates of H2 and CO2 leaving the separator The mass flow rate of H2 and CO2 leaving the separator
Problem #2:
As discussed earlier in the semester, a hydrotreater removes sulfur from organic compounds and saturates aromatics and olefins for fuel production. To perform these reactions, H2 must be added to the molecules. To get this needed hydrogen, Steam Methane Reforming (SMR) is used to convert steam and methane to CO2 and H2.
CH4 + 2H2O à CO2 + 4H2
Suppose a membrane separator, operating at 8 atm and 350 °F, is used to separate the H2 and CO2. Assuming the fluid behaves as an ideal gas, determine:
- SCFH going into the separator
- The true volumetric flow rate going into the separator
- The molar flow rates of H2 and CO2 leaving the separator
- The mass flow rate of H2 and CO2 leaving the separator
Since you have posted a question with multiple sub-parts, we will solve first three sub parts for you. To get remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.
The standard cubic feet per minute is SCFM. This is usually calculated at the temperature of fifty-nine degrees Fahrenheit. The pound mole per hour is converted into SCFM. The volumetric flow rate can be calculated from the ideal gas law where the molar flow rate is present with pressure and temperature. The stoichiometric equation is used to obtain the molar flow rates of hydrogen and carbon dioxide .
