成果简介	NOVELTY - Method of treating spent caustic stream generated from hydrogen sulfide (H2S) rich hydrocarbon stream treating unit involves (i) providing a H2S rich hydrocarbon stream comprises of H2S, mercaptan sulfur, (sulfurdioxide) SO2; (ii) reacting the H2S rich hydrocarbon stream with an aqueous caustic stream to form spent caustic stream in a H2S treating section; (iii) radiating the spent caustic stream with ultraviolent radiation in photolytic reactor and obtaining fuel hydrogen H2and treated sulfidic stream; and (iv) recycling treated sulfidic stream and obtaining the treated spent caustic solution. USE - Method of treating spent caustic stream generated from H2S rich hydrocarbon stream treating unit. ADVANTAGE - The method and system leads to the reduced consumption of the fresh aqueous caustic as it is regenerated by the process and is recycled in a process. Further, the spent caustic treated in the photolytic reactor leads to obtain the high valuable fuel H2, which is the most promising zero emission non-fossil fuel energy carrier and has a lot of commendable properties such as highest energy content per unit mass, wide flammability range, the lowest flashpoint (-230℃), high octane number of 130, very high flame speed with low ignition delay time. The method can be utilized in all refineries and gas plant that generate sulfidic spent caustic. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a system for treating spent caustic stream generated from the H2S rich hydrocarbon stream treating unit.
