A process for removing acid gases using a basic salt activated with a non-sterically hindered diamino compound. |
摘要 |
<p>Acidic gases containing carbon dioxide are removed from a normally gaseous mixture by absorbing CO2 from the gaseous mixture with an aqueous solution comprising a basic alkali metal salt or hydroxide and an activator or promoter system for the salt or hydroxide which contains (i) at least one non-sterically hindered diamino compound defined as a diamine having both a primary and a tertiary amino moiety wherein the primary amino moiety is attached to a primary carbon atom or as a diaminoalcohol having a tertiary amino moiety separated by four methylene groups from a primary amino moiety and having at least one hydroxyl group, and (ii) an amino acid, and desorbing at least partially the absorbed CO2 from the aqueous solution.</p> |
