Separations With Ionic Liquid Solvents

A method comprising:

• providing a process stream comprising an acid gas;
• capturing at least a portion of the acid gas from the process stream by an ionic liquid solvent;
• and
• recovering at least a portion of a captured acid gas from the ionic liquid solvent.

A system comprising:

• a process stream comprising a gaseous component;
• a separator comprising an ionic liquid solvent, wherein the separator receives the process stream, wherein the ionic liquid solvent captures at least a portion of the gaseous component;
• a captured stream exiting the separator and comprising the captured gaseous component captured in the ionic liquid solvent;
• and
• a regenerator to receive the captured stream, wherein the regenerator regenerates the ionic liquid solvent and emits at least a portion of a recovered gaseous component.
