ABSTRACT:
A gas (1) comprising hydrogen sulfide, carbon dioxide, and hydrocarbon contaminants is treated in a plant (FIG.2) in a configuration in which waste streams are recycled to extinction. In especially preferred aspects of contemplated methods and configurations, hydrogen sulfide and other sulfurous components are converted to a sulfur product (37), carbon dioxide (44A) is separated at a purity sufficient for enhanced oil recovery or sale, and hydrocarbon contaminants are purified to a marketable hydrocarbon product (49).
