Description
Technical field
The present invention relates to chemical equipment technical fields, and in particular to a kind of reactor that reaction is come into full contact with convenient for fluid,
And a kind of device for carrying out desulfurization to gas by slurry method.
Background technique
Slurry method desulfurization technology, also known as SDT slurry method or slurry method, may be implemented it is highly selective, expeditiously removing contain
Hydrogen sulfide in sulphur gas.The medicament that slurry method desulfurization uses is " unformed FeOOH (Amor-FeOOH) ".Hydroxyl oxygen
Change iron (FeOOH) desulfurization and regeneration principle is: the Sulfur capacity of FeOOH is big, with hydrogen sulfide H2The sulphur iron chemical combination that S reaction generates
Object is sulfydryl iron sulfide (FeSSH), and the sulfydryl iron sulfide of generation is regenerated by dioxygen oxidation, is converted into FeOOH, simultaneously
Elemental sulfur is precipitated.FeOOH after regeneration is recycled, and FeOOH is by desulfurization regeneration repeatedly, and granularity is gradually
Become smaller, is more advantageous to raising desulfuration efficiency.
Specific reaction mechanism are as follows: (1) hydrogen sulfide is dissolved in water and dissociates into HS-、H+Ion: H2S+A [alkali or water]=
HS-+HA+。(2)HS-、H+Lattice ion OH of the ion with FeOOH-、O2-Displacement generates sulfydryl iron sulfide FeSSH and water:
FeOOH+2H2S→FeSSH+2H2O.(3) redox reaction occurs under aerobic conditions for sulfydryl iron sulfide, generates hydroxyl oxidation
Simultaneously sulphur is precipitated in iron: FeSSH+O2→FeOOH+2S↓.Three reaction equations of above-mentioned reaction mechanism are merged, 2H is obtained2S+O2→
2H2O+2S↓.Whole process is H2S is oxidized to the reaction of elemental sulfur, and FeOOH only plays a part of catalyst, this
Body does not consume.FeOOH desulfurization has the characteristics that one is important: H2S is not removed with molecular conformation by FeOOH, and
It is first to dissociate into HS in the moisture film on FeOOH surface-、H+Ion, then with the Lattice Oxygen O in FeOOH2-And lattice
Hydroxyl OH-Ion exchange is carried out, therefore reaction process is rapid.
The device that slurry method desulfurization technology uses is double tower device, respectively absorption tower and regenerator, tower absorption, a tower

Enter shaftless fluid reactor 1 through the valve on piping, the sulphur in FeOOH (FeOOH) and natural gas in poor slurries
Change hydrogen (H2S) reaction generates sulfydryl iron sulfide (FeSSH).Purified natural gas is automatic by 3 top of slurries gas knockout drum
Control valve enters gas transmission line.The rich slurries of 3 bottom of slurries gas knockout drum are after Liquid level adjusting valve is adjusted, into follow-up process.
Since the reactor of actual participation reaction is composed of multiple shaftless fluid reactors 1, so can be according to operating condition
Difference determine optimal numbers shaftless fluid reactors 1, optimize reaction process.According to gas transmission sulfide hydrogen (H2S requirement),
The valve of shaftless 1 two sides of fluid reactor is adjusted to increase or shorten the length of response path, to ensure purified natural gas
Middle hydrogen sulfide (H2S) content is less than 20mg/m3, to ensure the quality and efficiency of desulfurization.
