The present invention relates to a process for recovering sulfur (S), carbon dioxide (CO2) and hydrogen (H2) from a gaseous stream, the process comprising: providing a first gaseous inlet stream and optionally a second gaseous inlet stream, both gaseous inlet streams comprising hydrogen sulfide (H2S) and CO2; a sulfur recovery step for recovering sulfur (S) from at least a portion of the H2S provided by the gaseous inlet stream to produce a liquid phase containing sulfur (S); a CO2 recovery step for recovering at least a portion of the CO2 provided by the gaseous outlet stream; and an H2 recovery step for recovering at least a portion of the H2 provided by the gaseous outlet stream. 本发明涉及一种从气态流中回收硫(S)、二氧化碳(CO2)和氢气(H2)的方法，该方法包括：提供第一气态入口流和可选地第二气态入口流，这两个气态入口流均包含硫化氢(H2S)和CO2；硫回收步骤，该硫回收步骤用于从由气态入口流提供的H2S的至少一部分中回收硫(S)，以产生含硫(S)的液相；CO2回收步骤，该CO2回收步骤用于回收由气态出口流提供的CO2的至少一部分；以及H2回收步骤，该H2回收步骤用于回收由气态出口流提供的H2的至少一部分。
