| World' s leading ammonia based desulfurization project in SRU units——Sinopec Jinlin Project |
| After comprehensive testing by authoritative testing institutions, all indicators of the absorber have reached the design requirements. |
| JNEP signed a contract with Sinopec Jinling Branch for the project of tail gas treatment system of 150000 T / a sulfur recovery unit. In this project, Claus tail gas and other waste gas from 150000 T / a sulfur recovery unit is put into the incinerator for peroxide incineration, and all hydrogen sulfide and organic sulfur in the tail gas will be converted into sulfur dioxide to ensure that H2S + COS + CS2 ≤ 10ppm to meet the requirements of ammonia desulfurization. After waste heat recovery, incineration flue gas is sent to ammonia based desulfurization unit. Inlet of desulfurization unit: actual flue gas volume 74347 Nm3 / h, flue gas temperature 270 ℃, sulfur dioxide content 18400mg / Nm3; After the operation of the desulfurization unit, the sulfur dioxide emission concentration in the outlet flue gas is less than 50mg / Nm3, the desulfurization efficiency should is less than 99.8%, and the ammonia slip is no more than 5mg / Nm3; The utilization rate of ammonia is not less than 99%. All the stats can meet the emission standard. |
