Considering the sulfuric acid-containing gas (such as H₂S and SO₂) in the waste gas of the Shanghai Petrochemical Acrylonitrile Apparatus, an injection, absorption, and desulfurization technology is developed for the pilot test of sulfur-containing waste gas in the acrylonitrile apparatus, under the operating conditions of the apparatus and the characteristics of the waste gas. A single hydraulic jet swirl core tube is adopted to study the effects of H₂S gas concentration, SO₂ gas concentration, NaOH absorption concentration, and intake air amount on desulfurization efficiency. Results show that under the smooth operation of the apparatus, the absorption efficiency of H₂S gas and SO₂ gas can continuously reach 85 % and 70 % respectively. The absorption efficiency is increased with the increased concentrations of H₂S gas and SO₂ gas as well as the increase of the liquid volume of the absorption liquid. However, the absorption efficiency decreased as the amount of air intake increases. The findings can serve as valuable reference for the use of injection, absorption, and desulfurization technology in engineering applications.

考虑到上海石化丙烯腈装置废气中的含硫酸气体（如H ₂ S和SO ₂），开发了一种进样，吸收和脱硫技术，用于上海石化丙烯腈装置的中试。丙烯腈装置，在装置的操作条件和废气的特性下。采用单个水力喷射旋流芯管研究H ₂ S气体浓度，SO ₂气体浓度，NaOH吸收浓度和进气量对脱硫效率的影响。结果表明，在装置运行平稳的情况下，H ₂ S气体和SO ₂的吸收效率气体分别可以连续达到85％和70％。随着H ₂ S气体和SO ₂气体的浓度增加以及吸收液体的液体体积的增加，吸收效率增加。然而，吸收效率随着进气量的增加而降低。这些发现可为工程应用中注入，吸收和脱硫技术的使用提供有价值的参考。
