Abstract
A system and method for optimizing operation of a rotating packed bed desorber or regenerator wherein a rich solvent is input and CO2 product and lean solvent are output includes collecting condensed water from a regeneration section of a rotating packed bed desorber system. The collected condensed water is then repressurized and reheated to generate steam and the steam is injected into the rotating packed bed desorber or regenerator as stripping vapors while heating rich solvent.
Claims16
A method for optimizing operation of a rotating packed bed desorber or regenerator system wherein a rich solvent is input and CO2 product and lean solvent are output, the method comprising:
- collecting condensed water from a regeneration section of a rotating packed bed desorber system;
- repressurizing the collected condensed water;
- reheating the collected condensed water to generate steam;
- and
- injecting the generated steam to the rotating packed bed desorber or regenerator as stripping vapors while heating the rich solvent.
A system for optimizing operation of a rotating packed bed desorber or regenerator wherein a rich solvent is input and CO2 product and lean solvent are output, the system comprising:
- a knockout separator collecting condensed water from a regeneration section of the rotating packed bed desorber or regenerator;
- a pressure pump configured to repressurize collected condensed water;
- a steam generator positioned downstream of the pressure pump, the steam generator configured to reheat the collected condensed water to generate steam;
- and
- an injector configured to inject the generated steam to the rotating packed bed desorber or regenerator as stripping vapors while heating the rich solvent.
