METHOD AND APPARATUS FOR CONVERTING HYDROGEN SULPHIDE TO HYDROGEN AND SULPHUR

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to chemistry and can be used in producing hydrogen and sulphur. Initial gas, which is an acidic gas containing hydrogen sulphide, undergoes first separation in a first separation device to obtain a first purified fraction of hydrogen sulphide, where the first purified fraction of hydrogen sulphide contains at least approximately 90 vol. % hydrogen sulphide; said first purified fraction containing hydrogen sulphide is then taken for hydrogen sulphide dissociation in a dissociation device to convert the first purified fraction of hydrogen sulphide into a dissociated first fraction of hydrogen sulphide, where the dissociated first purified fraction of hydrogen sulphide contains elementary hydrogen and elementary sulphur. The dissociated first purified fraction of hydrogen sulphide undergoes second separation in a second separation device to obtain a hydrogen-rich fraction containing elementary hydrogen and a hydrogen product from the hydrogen-rich fraction in a third separation device. ^ EFFECT: invention increases efficiency. ^ 69 cl, 1 dwg
