A refining system for refining a feed gas comprising hydrocarbons and hydrogen sulfide having a first concentration of hydrogen sulfide includes a first part for producing a stream of a first processed feed gas, a second part for producing a second stream of a second processed feed gas from the stream of the first processed feed gas using a separation process for H2S removal. The second part includes a cyclonic separator (40) with a first inlet (42) and a second inlet (44,47,144) and that is arranged for: receiving at the first inlet the stream of first processed feed gas, receiving at a distal side of the second inlet a flow of additive component, the additive component being a solvent for hydrogen sulfide; spraying from the second inlet the flow of additive component into the first processed feed gas stream so as to form a mixture of sprayed additive and first processed feed gas, and creating at a first outlet (7) a first flow of the second processed feed gas and at a second outlet (46) a second flow of substantially hydrogen sulfide containing liquid, the second processed feed gas having a second concentration of hydrogen sulfide, the second concentration being relatively lower than the concentration of the stream of the first processed feed gas, received at the first inlet. |
