Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization, in particular to a device for treating trace carbon disulfide in cracking carbon five. Background Art

[0002] Petrochemical enterprises produce C5 mainly from atmospheric and vacuum units and naphtha or straight-run gasoline cracking units. The output of C5 is generally below 100,000 tons / year, and the scale is relatively small. Saturated C5 with less olefins is generally used to blend finished gasoline, while unsaturated C5 with higher olefins is mostly used as a polymerization raw material for producing petroleum resins or other chemical products.

[0003] Research and analysis show that the sulfur forms in C5 mainly include organic sulfur such as sulfide, mercaptan, carbon disulfide, and thiophene. The C5 produced by some equipment may also contain a small amount of hydrogen sulfide, carbonyl sulfide, and disulfide. When treating the trace carbon disulfide in C5, high-temperature distillation is generally used. After adding a desulfurizer, the C5 is heated at a high temperature to cause distillation. The cracked C5 is separated and discharged from the top, while the sulfur compound components are discharged from the bottom, thereby achieving effective carbon disulfide treatment and separation.

[0004] However, during the addition process of the existing desulfurizer, it is generally injected directly through a feed pipe, which makes the desulfurizer easily accumulate locally, thereby affecting the rapid mixing of the desulfurizer and C5. Therefore, the present application proposes a device for treating trace carbon disulfide in cracking C5. Utility Model Content
