  • Mass Balances on CO2 Absorption/Stripping Process

    Typical absorber/stripper flow sheet for CO2 capture. The absorption/stripping system can be placed at the end of new or existing coal fired power plants with NOx and SOx controls. Amine solvents are used since they react with CO2 under certain conditions. A lean solvent (low CO2 concentration) is fed into the top of the absorber.

  • Mass balance - Wikipedia

    A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem ...
