Embodiment 1
[0079] Use as figure 1 The treatment method and device shown use acid gas and NaOH solution as raw materials to carry out the reaction. CO in acid gas 2 The volume fraction is 7%, H 2 The volume fraction of S is 92%, and the volume fraction of hydrocarbons is 1%. The mass concentration of NaOH solution is 38%.
[0080] In Example 1, the first-stage reactor and the second-stage reactor adopt a venturi reactor, and the third-stage reactor and the fourth-stage reactor adopt a rotating bed reactor. The venturi reactor and the rotating bed reactor can be in the field General purpose Venturi reactor and rotating bed reactor.
[0081] In Example 1, the volume flow ratio of the reaction product liquid of the second path circulating back to the primary reactor to the total reaction product liquid of the primary reactor is 5:6. The volume flow ratio of the second reaction product circulating back to the secondary reactor to the total reaction product of the secondary reactor is 1:2. The v...
Embodiment 2
[0084] Use as figure 2 The process method and system shown, in Example 2, the primary reactor and secondary reactor are used image 3 The Venturi reactor, the three-stage reactor and the four-stage reactor shown use rotating bed reactors.
[0085] In Embodiment 2, the volume flow ratio of the reaction product circulating back to the first reactor through the absorption liquid inlet of the first reactor to the total reaction product of the first reactor is 5:8. The volume flow ratio of the reaction product circulating back to the first reactor through the circulating liquid inlet of the first reactor to the total reaction product of the first reactor is 5:24.
[0086] The volume flow ratio of the reaction product circulating back to the secondary reactor through the absorption liquid inlet of the secondary reactor to the total reaction product liquid of the secondary reactor is 1:3. The volume flow ratio of the reaction product circulating back to the secondary reactor through the...
