Question

During manufacture of Hydrogen through the Bosch Process, separation of carbon dioxide can be done by:

• A. mixing the solution with excess steam
• B. passing the solution through cold water under 30 atm
• C. passing the solution through the ammoniacal cuprous chloride solution
• D. passing the solution through caustic potash solution

Answer 1

Answer: (B), (D)

The correct options are
B

passing the solution through cold water under 30 atm

D

passing the solution through caustic potash solution

$C{O}_2+H_2$ solution is passed through cold water under the pressure of 30 atm or it is passed through the caustic potash solution which dissolves the carbon dioxide.

$2KOH+C{O}_2⟶K_{2}C{O}_3+H_{2}O$
