1. A process for treating a carbon dioxide and/or hydrogen sulfide containing gas comprising:

  • a) sending a feed gas containing carbon dioxide and hydrogen sulfide through a carbon dioxide and/or hydrogen sulfide absorber unit containing a lean solvent to produce a loaded solvent containing a majority of said carbon dioxide and/or hydrogen sulfide from said feed gas and a treated gas;

    b) regenerating said loaded solvent in a carbon dioxide and or hydrogen sulfide removal system; and

    c) recovering energy from at least one solvent stream to boost pressure of at least one other solvent stream wherein at least one hydraulic turbocharger is used to recover said energy wherein said energy is recovered in a form of electricity.
