Dye administers action scheme, and the wherein implementation of Filter Tuber For Clean Coal application plan effectively improves the air dirt caused by coal use
Dye problem.In numerous Coal Clean occupation modes, coal vaporization production combustible gas (water-gas) is to Substitute coal direct fired technology
It is a kind of more efficient, clean coal utilization mode.Coal Gasification Technology is in our building material industries, especially ceramic industry at present
Using the most universal.Although the concentration of flue gas pollutants that water-gas burning generates compared with coal directly burns is relatively low, especially
Particle concentration is relatively low, but such as SO2The concentration of emission of equal sour gas is still very high.Reason is to produce water-gas process
About 95% sulphur (S) is with H in middle coal2S, the situation of organic sulfur is run into water-gas, and most of factory's coal gas at present
It stands and desulfurization equipment is not installed, finally with SO in water-gas combustion process2Situation is present in flue gas.Although in addition, factory
Gas station is mounted with electrical tar precipitator, eliminates most of tar, but still has a small amount of tar to be present in water-gas, with dampening coal
The combustion decomposition of gas generates flue gas pollutant.Therefore as can carrying out deep desulfuration and oil removing to it before water-gas burning, then
The concentration of flue gas pollutants of water-gas burning and exhausting can be lower, more meets the objective of cleaning coal utilization, while also avoiding follow-up
Flue gas desulfurization problem.
Currently, it is domestic seldom for the patent of desulfurization of water gas, technology report, but with coal gas, oven gas, natural gas
For waste methanol, synthesis ammonia, synthetic oil factory have gas fine de-sulfur process, generally using low-temp methanol absorption process,
The methods of NHD (polyethylene glycol dimethyl ether) absorption process, fine desulfurization process by dry.In addition, patent 201610115440.0 discloses one kind
The method of raw gas decarbonization, desulfuration, by dehydration, filtering, the first cooling procedure, the second cooling procedure and etc. realize that coal gas is de-
Carbon desulfurization, but this method equipment is more, complex process, and especially by gas cooling to -90~-60 DEG C, pressure will increase to 3.5
~8Mpa requires height to process equipment, and energy consumption is high.Patent 201510375624.6 disclose a kind of super desulfurizing agent and
Preparation method, super desulfurizing agent are that solid is made of carrier and active component, are prepared using excessive infusion process, use takes off
Sulphur technique is dry process.Patent 201410632507.9 discloses a kind of synthetic raw gas depth fine desulfurizing technology and its dress
It sets, by what titanium-based cobaltmolybdate catalyst, what Zinc oxide desulfurizer and level-one multi-function fine desulfurizing agent, realizes deep desulfuration,
But the sulfur removal technology that the technology uses is dry process, and equipment is more, complex process.
As it can be seen that the country develops more unstripped gas sulfur method, but process equipment in industries such as synthesizing methanol, ammonia at present
It is complicated, investment operating cost is high, directly replication application can not arrive the field that gaseous fuel is done with water-gas, while domestic in the neck
Domain also lacks desulfurization technological reserve.
