FIELD: technological processes.
SUBSTANCE: invention relates to the technology of gas desulfurization and the recovery of enriched desulfurization solution and can be used in the processing of coal, the development of oil and gas, oil refining and petrochemical production. Desulfurization-regeneration system contains a suspension bed reactor filled with a desulfurization suspension, a gas-liquid separator, a fixed bed reactor, an instantaneous boil-off evaporator and an oxidative regeneration tank. System combines primary desulfurization in a suspension layer with deep desulfurization in a fixed bed. Spent desulfurization solution can be regenerated by reacting the oxygen-containing gas with an enriched solution, and the resulting lean solution can be reused in the process as a desulfurization suspension.
EFFECT: high efficiency of desulfurization, simplicity of the process, low investment in equipment and the absence of secondary pollution.
