Integrated optimized horizontal boxed amine carbon capture system for post combustion emissions

An apparatus to capture carbon dioxide from a post combustion exhaust, such as from an engine, comprising;

• feeding hot exhaust through ducting or piping to a rectangular boxed, and horizontally arranged series of vertical contactor vessels;
• cooling the engine exhaust with a direct counter current contact water spray using mass and heat transfer arrangement in an internal chamber;
• directing the cooled exhaust through an internal channel to a second internal chamber to be contacted by a direct counter current contact chilled lean liquid CO2 absorbent (e.g., amine) spray using mass transfer arrangement to capture carbon dioxide;
• directing the carbon dioxide reduced exhaust stream through another internal channel to a third or more internal chamber(s) to be contacted a second or more time(s) by a direct counter current contact chilled lean liquid CO2 absorbent (e.g., amine) to remove additional carbon dioxide;
• and
• directing the carbon dioxide depleted exhaust stream through another internal channel to a subsequent internal chamber to be contacted by a direct counter current contact water spray and mass transfer arrangement to prevent entrained liquid CO2-rich absorbent from leaving the vessel to atmosphere.

A method to capture carbon dioxide from a post combustion exhaust, such as from an engine, said method comprising the following steps;

• feeding hot exhaust through ducting or piping to a rectangular boxed, and horizontally arranged series of vertical contactor vessels;
• cooling the engine exhaust with a direct counter current contact water spray using mass and heat transfer arrangement in an internal chamber;
• directing the cooled exhaust through an internal channel to a second internal chamber to be contacted by a direct counter current contact chilled lean liquid CO2 absorbent (e.g., amine) spray using mass transfer arrangement to capture carbon dioxide yielding a resulting carbon dioxide reduced exhaust stream;
• and
• providing at least one of the following steps:
• directing the resulting carbon dioxide reduced exhaust stream through another internal channel to a third or more internal chamber(s) to be contacted at least one more time by a direct counter current contact chilled lean liquid CO2 absorbent (e.g., amine) to remove additional carbon dioxide resulting in a the carbon dioxide depleted exhaust stream;
• and
• directing the carbon dioxide depleted exhaust stream through another internal channel to a subsequent internal chamber to be contacted by a direct counter current contact water spray and mass transfer arrangement to prevent entrained liquid CO2-rich absorbent from being released as a gas into the atmosphere.
