A plant for treating a feed gas having an H 2 S concentration of less than 10% and comprising carbon dioxide, comprising: - a first absorber which receives: - the feed gas; and - a portion of a lean hydrogen-sulfide-selective solvent; - and which is configured to: - promote absorption of hydrogen sulfide from the feed gas by the portion of the lean hydrogen-sulfide-selective solvent; and to - produce a first hydrogen-sulfide-enriched solvent; and to - produce a first overhead product enriched in carbon dioxide and substantially depleted in hydrogen sulfide; - a second absorber which receives: - another portion of the lean hydrogen-sulfide-selective solvent; and - a portion of a hydrogen-sulfide-rich gas: - and which is configured to produce: - a second hydrogen-sulfide-enriched solvent; and - a second overhead product enriched in carbon dioxide and substantially depleted in hydrogen sulfide; - a regenerator which receives: - a combined hydrogen-sulfide-enriched solvent formed by combining the first hydrogen-sulfide-enriched solvent and the second hydrogen-sulfide-enriched solvent; - and which is configured to: - produce the lean hydrogen-sulfide-selective solvent; and to - promote formation of the hydrogen-sulfide-rich gas; - and an acid gas incineration unit which receives: - a combined first overhead product and second overhead product enriched in carbon dioxide and substantially depleted in hydrogen sulfide; - and a sulfur plant which receives: - another portion of the hydrogen-sulfide-rich gas; - and which is configured to: - produce a tail gas. - a first absorber which receives: - the feed gas; and - a portion of a lean hydrogen-sulfide-selective solvent; - the feed gas; and - a portion of a lean hydrogen-sulfide-selective solvent; - and which is configured to: - promote absorption of hydrogen sulfide from the feed gas by the portion of the lean hydrogen-sulfide-selective solvent; and to - produce a first hydrogen-sulfide-enriched solvent; and to - produce a first overhead product enriched in carbon dioxide and substantially depleted in hydrogen sulfide; - promote absorption of hydrogen sulfide from the feed gas by the portion of the lean hydrogen-sulfide-selective solvent; and to - produce a first hydrogen-sulfide-enriched solvent; and to - produce a first overhead product enriched in carbon dioxide and substantially depleted in hydrogen sulfide; - a second absorber which receives: - another portion of the lean hydrogen-sulfide-selective solvent; and - a portion of a hydrogen-sulfide-rich gas: - another portion of the lean hydrogen-sulfide-selective solvent; and - a portion of a hydrogen-sulfide-rich gas: - and which is configured to produce: - a second hydrogen-sulfide-enriched solvent; and - a second overhead product enriched in carbon dioxide and substantially depleted in hydrogen sulfide; - a second hydrogen-sulfide-enriched solvent; and - a second overhead product enriched in carbon dioxide and substantially depleted in hydrogen sulfide; - a regenerator which receives: - a combined hydrogen-sulfide-enriched solvent formed by combining the first hydrogen-sulfide-enriched solvent and the second hydrogen-sulfide-enriched solvent; - a combined hydrogen-sulfide-enriched solvent formed by combining the first hydrogen-sulfide-enriched solvent and the second hydrogen-sulfide-enriched solvent; - and which is configured to: - produce the lean hydrogen-sulfide-selective solvent; and to - promote formation of the hydrogen-sulfide-rich gas; - produce the lean hydrogen-sulfide-selective solvent; and to - promote formation of the hydrogen-sulfide-rich gas; - and an acid gas incineration unit which receives: - a combined first overhead product and second overhead product enriched in carbon dioxide and substantially depleted in hydrogen sulfide; - a combined first overhead product and second overhead product enriched in carbon dioxide and substantially depleted in hydrogen sulfide; - and a sulfur plant which receives: - another portion of the hydrogen-sulfide-rich gas; - another portion of the hydrogen-sulfide-rich gas; - and which is configured to: - produce a tail gas. - produce a tail gas.
