Description
Technical field
The utility model relates to a kind of system for removing hydrogen sulfide in molten sulfur, belongs to molten sulfur degasification technical field.
Background technology
In the partial devices in the field such as coal, oil and natural gas, can produce hydrogen sulfide containing gas, hydrogen sulfide is hypertoxicity material, needs strictly to process.At present, the main technique of process hydrogen sulfide is claus process, and this process application is very extensive.Kraus process process hydrogen sulfide technology generally comprises following steps:
1, H
2s partial oxidation: part H
2s and O
2reaction generates SO
2;
2, claus reaction: SO
2with H
2s reacts generting element S (gas), and element S condenses into molten sulfur, unreacted H after condenser cooling
2s and SO
2remove next stage reactor, repeat above-mentioned steps;
3, the unreacted waste gas of final stage removes tail gas treating unit.
H containing more dissolving from the molten sulfur that condenser reclaims
2s and hydrogen polysulfide (H
2s
x), total content is generally 250 ~ 450 μ g/g.H
2s is the virose gas of tool, is also inflammable gas simultaneously.When transporting, storage, in the process such as use, H in molten sulfur
2s discharges, on the one hand serious environment pollution, and etching apparatus, threat operator ' s health, go back the security incident such as fire hazard or blast time serious on the other hand.In addition, more H is contained in Molten sulphur
2s, the fragility of solid sulfur product can significantly improve, and affects the quality of sulfur product.Therefore, the molten sulfur reclaimed from condenser has to pass through depriving hydrogen sulphide process, just can enter next step operation.It is generally acknowledged, total H in molten sulfur
2s should higher than 15 μ g/g.Common liquid sulphur degasification technique has following several: circulation degassing method, bubbling degassing method, air oxidation process etc.
Circulation degassing method is in molten sulfur degasification pond, inject a small amount of catalyzer (being generally basic catalyst), impels hydrogen polysulfide to decompose, then makes hydrogen sulfide escape into gas phase, with sweep gas-N by the circulation-sprinkling process of molten sulfur degasification pump
2by H
2s drives out of, and waste gas steam injector is drawn in burner for producing sulfur or tail gas burning furnace and burns.Shortcoming be in molten sulfur pond the residence time long, be greater than 24 hours, in degassed rear molten sulfur, hydrogen sulfide content is less than 50ppm, molten sulfur entrucking and forming unit peculiar smell still larger.Basic catalyst generally uses ammonia and quinoline etc.Ammonification easily forms ammonium salt NH
4hS, can be adsorbed on impact heat transfer on heating steam coil pipe, easily cause molten sulfur evacuation pipeline to block.During use quinoline, on-the-spot chemical industry peculiar smell is larger.
Bubbling is degassed is the degassed pond by special bubbling facility, air dispersion being injected molten sulfur pond, by the H dissolved in molten sulfur
2s stripping enters gas phase, and waste gas vapor steam blaster is drawn to tail gas burning furnace and burns, and enters the SO that tail gas burning furnace can increase sulfur recovery unit
2emission concentration 100 ~ 200mg/m
3.After some enterprises bubbling, tail gas enters caustic treater alkali and neutralizes, but caustic treater is often blocked by sulphur powder, need irregularly clear up, cumbersome.
Air oxidation process is the fixed bed degassing tower by designing separately, carry out degassed under the effect of catalyzer (alumina base), molten sulfur is sent into degassing tower after pump promotes and cools together with pressurized air at the bottom of tower, under catalyst action, oxygenizement occurring, is sulphur by Oxidation of Hydrogen Sulfide.Lower because there is catalyzed reaction temperature, generate molten sulfur and be deposited on catalyst surface, easily cause catalyzer to harden inefficacys, device run stability is poor, hydrogen sulfide content instability in molten sulfur.
