Abstract: The proposed techniques relate to removing heat stable amine salts (HSAS) from a contaminated aqueous amine absorption solution containing amine in salt form generated during an amine-based acid gas recovery operation, while reducing or avoiding discharging any liquid waste. At least a portion of the HSAS is removed from the contaminated aqueous amine absorption solution in an amine reclamation unit to produce a waste stream containing dissolved salts and/or acids, and a regenerated amine absorption solution containing a reduced amount of the heat stable amine salts. The waste stream is further treated by oxidizing the waste stream into an oxidized product stream comprising CO2, water, and nitrogen. Optionally, the concentration in dissolved salts and/or acids of the waste stream can be increased prior to oxidation. The oxidation can advantageously be operated in a combustion unit that produces a flue gas directed to acid gas recovery as part of an integrated process.

Abstract: Processes for removing heat stable amine salts from a contaminated aqueous amine solution are proposed comprising passing a feedstream of the contaminated aqueous amine solution in an electrodialysis zone comprising at least one repeat unit with an amine solution compartment for receiving the feedstream, a waste compartment, and an anion source compartment receiving an anion source stream or a bi-polar membrane disposed for providing anions balancing the heat stable anions. Monitoring of an anion source-related parameter being correlated to the anion source concentration of the anion-depleted source stream, or of a waste parameter being correlated to an acid concentration of the waste stream, is performed to further adjust an addition of the anion source or a removal of the waste stream in accordance with the monitored parameter.

Abstract: A method for removing heat stable base salts, such as amine salts, is disclosed. The method of the present invention can be used to reduce the level of heat stable salts in a solvent gas stream in an acid gas removal process. A solvent in which the lean acid gas loading is high is first stripped to achieve an acceptable lean gas loading. The lean solution is then reclaimed using one or more methods. The purified base or amine solution can be used again to remove acid gases from a gas stream. A process for recovering acid gas from an acid gas stream is also disclosed. The process also comprises a reduction of the level of heat stable salts in the solvent gas stream.

Abstract: A process for purifying polyethylene glycol dimethyl ethers (PGDE) based absorbent (known as Selexol®) having acidic contaminants and salts thereof, this process being particularly useful in an acid gas removal loop process (known as Selexol® process). A base, such as ammonium hydroxide (NH3OH), is added to the absorbent to partly of fully convert the acid into simple salts. The salts are removed in an electrodialysis cell. The base can be added directly to the absorbent either from a fresh chemical feed or as base contained in the re-generator's generator's reflux stream. Alternatively the base can be added directly into the electrodialysis unit. The solution is diluted before electrodialysis. The absorbent can be simultaneously diluted and neutralized using reflux from the regeneration section that contains dissolved ammonia. The purified solution can be used again to remove carbon dioxide, hydrogen suphide, sulfur dioxide, mercaptans and other acid gases from a gas stream.
