    Abstract: A syngas treatment plant is configured to remove sulfurous compounds from syngas in a configuration having two flash stages for a physical solvent to so enrich the acid gas to at least 40 mol % H2S or higher as required by the Claus unit and to flash and recycle CO2 back to the syngas feed. Contemplated methods and configurations advantageously remove sulfur to less than 10 ppmv while increasing H2S selectivity at high pressure operation to thereby allow production of an H2S stream that is suitable as feed gas to a Claus plant.

    Abstract: Acid gas is removed from a feed gas using a physical solvent that is regenerated using successive flashing stages after heating of the rich solvent using low-level waste heat that is preferably produced or available within the acid gas removal plant. Especially preferred waste heat sources include compressor discharges of the refrigeration system and/or recompression system for CO2, and/or (low level) heat content from the feed gas.

    Abstract: Controlled RVP C5+ products are produced from feed gas in configurations and methods in which a heavier portion of the feed gas is fractionated into several streams having distinct RVP and in which a C5+ stream is produced from the lighter portion of the feed gas. The so formed streams are then combined to produce C5+ products with controlled RVP. Thus, RVP control is achieved without the need for external products for blending process streams derived from the feed gas.

    Abstract: Contemplated methods and configurations use a cooled ethane and CO2-containing feed gas that is expanded in a first turbo-expander and subsequently heat-exchanged to allow for relatively high expander inlet temperatures to a second turbo expander. Consequently, the relatively warm demethanizer feed from the second expander effectively removes CO2 from the ethane product and prevents carbon dioxide freezing in the demethanizer, while another portion of the heat-exchanged and expanded feed gas is further chilled and reduced in pressure to form a lean reflux for high ethane recovery.

    Abstract: A sulfur species-containing feed gas is processed in a treatment plant in which COS is hydrolyzed, and in which so produced hydrogen sulfide and other sulfur species are absorbed in a lean hydrocarbon liquid. The sulfur species in the so formed rich hydrocarbon liquid are then subjected to catalytic conversion into disulfides, which are subsequently removed from the rich solvent. Most preferably, sulfur free lean solvent is regenerated in a distillation column and/or refinery unit, and light components are recycled from the rich hydrocarbon liquid to the absorber.
