Gas Purification Apparatus with Eductors

A system includes an eductor configured to contact an acid gas stream with a primary stream including an aqueous metal chelant and release an eductor outlet stream including CO2 gas and aqueous metal chelant. A chamber is connected to an outlet of the eductor, and the chamber is configured to receive the eductor outlet stream. The chamber includes a sidewall defining a gas outlet and a primary stream outlet such that the chamber is configured to separate the eductor outlet stream into a CO2 gas stream and the primary stream. The eductor includes a motive fluid inlet, and the primary stream extends from the motive fluid inlet to the primary stream outlet such that the primary stream is configured to circulate the aqueous metal chelant from the chamber to the eductor.
