Description

The processing method of the foul waste gas of a kind of sulfur-bearing and dust

Technical field

The present invention relates to the processing method of the foul waste gas of harmful constituents such as method, particularly sulfur-bearing that the foul waste gas of a kind of sulfur-bearing and dust handles, dust, hydro carbons volatile matter.

Background technology

In the oil refining enterprise; Catalyst is indispensable core product; In producing the catalyst process; Because catalyst needs processes such as heating, roasting, thereby Catalyst Production equipment will produce the complex waste gas that various components such as containing dust, sulfide (hydrogen sulfide and sulfur-containing organic compound), VOCs (organic volatile), ammonia mix inevitably.The long-term activity of worker possibly cause diseases such as respiratory system, digestive system, reproductive system in the environment that is polluted by these materials, also possibly cause body disease and carcinogenic; When seriously polluted, also can make the people produce dizziness, larynx painful, feel sick, acute poisoning symptom such as vomiting.

These waste gas components are complicated, not only cause the odor pollution of surrounding enviroment, also worker health threatened.Therefore must administer this type waste gas.This type waste gas characteristics are that exhausted air quantity is little, the intermittent generation, and Dust Capacity is big, and component is complicated.

Traditional exhaust gas treatment method such as absorption method, burning method, Production by Catalytic Combustion Process, condensation method, absorption process etc. can not be administered this type waste gas well.The used adsorbent of existing absorption method directly adsorbs this type of waste gas makes adsorbent bed obstruction very soon easily, thereby treating apparatus can not be moved.Because this type of waste gas intermittently produces, thereby there is high, the less economical shortcoming of energy consumption in burning method.Though the Production by Catalytic Combustion Process energy consumption reduces, waste gas component is complicated, and also there is the beds blocking problem simultaneously in the easy poison deactivation of catalyst.Condensation method and absorption process only can be removed the part component in this type of waste gas.

CN01127539.1 has introduced a kind of method that purifies hydrogen sulfide, and CN1133568A has introduced the method that a kind of absorption process is removed hydrogen sulfide.CN91110451.8 has introduced the method for recovering solvents in a kind of hydro carbons process.These methods all only can be removed hydrogen sulfide or hydro carbons.Foul waste gas improvement for sulfur-bearing and dust does not still have better method.

" petrochemical industry environmental protection " 2005 28 the 4th phases of volume have been introduced the improvement method that adopts absorption process purification of sulphur-containing sewage jar waste gas.This method adopts the secondary absorption process to handle acid water pot waste gas, and absorbent is an alkaline solution.The tail gas that several sour water jars and alkaline residue jar are extracted through jet pump earlier with alkali lye blended absorbent in venturi mixer; In alkali liquid tank, carry out gas-liquid separation; Absorb processing through one-level alkali lye absorption tower and secondary deodorant absorption tower then, be pooled to the laggard smoke stack emission of deodorant jar gas-liquid separation at last.But this technology only can transform the sulfide oxidation that absorbs, but does not remove the ability of hydro carbons.

" design of sulphur phosphorus and powder technology " the 6th phase in 2004 has been introduced the waste gas that adopts solid absorbent adsorption cleaning sour water jar.This method adopts the swage adsorbent that this waste gas is handled, and has obtained certain effect.But this method only purifies hydrogen sulfide, and other pollutant does not purify, and also there is safety problem in adsorbent.

Existing absorption method is all used the single hop bed, adopts active carbon or NACF usually.Patent CN03254728.5CN03254729.3, CN200410023944.7, CN02805902.6 and CN00118594.2 have all proposed by active carbon hydro carbons to be adsorbed, and carry out steam desorb condensing and recycling or vacuum desorption solvent then and absorb the method that reclaims.Patent CN03254728.5 CN03254729.3 has proposed the device that a kind of absorption method oil gas reclaims respectively, adopts active carbon as adsorbent, and the hydro carbons behind the vacuum desorption absorbs as liquefied gas or diesel oil.With active carbon or NACF is adsorbent, and its advantage is that adsorbance is bigger, and adsorption efficiency is higher, and discharging tail gas reaches the environmental protection index requirement easily.

But above-mentioned method is handled this type of waste gas of the present invention and uneconomical; In the sulfur-bearing involved in the present invention and the foul waste gas of dust, the VOCs amount is less, and needing further after the recovery, processing just has value; For the value that VOCs embodied that is reclaimed, and uneconomical.

In addition, for the sulfide in this type of waste gas, adopt traditional sulfur recovery technology more uneconomical, the sulfide concentration that the present invention relates to is less than 1% (volume ratio), and traditional sulfur recovery technology concentration of hydrogen sulfide is generally more than 10% (volume ratio).

Summary of the invention

Deficiency to above-mentioned prior art; The present invention proposes the purification method of the foul waste gas of a kind of sulfur-bearing and dust; The occasion of sulfide, ammonia and hydrocarbon gas that the present invention can be applicable to produce in the various production processes is specially adapted to the foul waste gas that the Catalyst Production device produces.It is simple that the present invention has flow process, no safety issue, the advantage that the adsorbent life-span is long.

The processing method of sulfur-bearing of the present invention and dust foul waste gas comprises following content: waste gas adopts the liquid-absorbent dust removal process, and the liquid-absorbent dust removal process can remove harmful miscellaneous material through solid absorbent then.Wherein the liquid-absorbent dust removal process is an absorption and washing liquid with the aqueous solution that contains additive, and additive comprises cleaning agent, and additive can also comprise alkaline matter or oxidant.Cleaning agent is the material with cleaning organic matter function, specifically can use in surfactant, washing agent, emulsifying agent, the dispersant etc. one or more.The cleaning agent consumption is 0.1%~50% of an absorption and washing liquid by weight, is preferably 2%~20%.

Absorption and washing can adopt various suitable equipment, as being packed tower washing facility, whirlwind washing facility, self-excitation spray washing equipment, plate type washing equipment, Venturi scrubbing equipment, hypergravity absorption equipment, mechanical induction spray washing equipment, catheter type absorption and washing equipment etc.The air speed of waste gas in absorption and washing equipment is 100h -1~20000h -1, preferred 200~5000h -1, liquid-gas ratio is 0.2~50L/m 3, preferred 0.5~20L/m 3, 1.0~15L/m most preferably 3

Composition according to waste gas in the absorption and washing liquid can add other additive types; For example contain hydrogen sulfide in the waste gas more for a long time; Can add alkaline matter and absorb,, can when adding alkaline matter, add oxidant if organic sulfur compound content is more in the waste gas.Above-mentioned additive can make the sulfide part in the absorption and washing dust removal process in the waste gas remove, and reduces the load of follow-up desulfuration adsorbent.

The kind of solid absorbent can be selected according to the kind of objectionable impurities in the waste gas, can adopt desulfuration adsorbent to purify like sulfur-containing compound, and volatile organic matters such as hydro carbons can adopt and take off the hydrocarbon adsorbent purification.Desulfuration adsorbent with take off hydrocarbon adsorbent and can use the conventional adsorbent in this area, can be active carbon type desulfurizing agent, metal oxide type desulfurizing agent, alkali type desulfurizing agent etc. like desulfuration adsorbent.Taking off hydrocarbon adsorbent can be materials such as silica gel, aluminium oxide, molecular sieve, zeolite, active carbon.Desulfuration adsorbent with take off hydrocarbon adsorbent and can be seated in the absorber, also can be seated in respectively in the different adsorption device.Waste gas is earlier through desulfuration adsorbent, then through taking off hydrocarbon adsorbent; Can pass through desulfuration adsorbent then earlier through taking off hydrocarbon adsorbent; Also can and take off hydrocarbon adsorbent and mix use desulfuration adsorbent.Desulfuration adsorbent with take off the flow of the consumption of hydrocarbon adsorbent, the concentration of sulfide and hydro carbons in the waste gas, and the factors such as operation cycle that designed are definite according to waste gas.

In the foul waste gas of hydrocarbon-containifirst and dust; The less dust of particle generally is difficult for removing with common cleaning dust mode; The dust that does not remove has certain influence to follow-up waste gas treatment process, particularly to adopting the fixed bed waste gas treatment process to have bigger influence, because these dust deposits are in ADSORPTION IN A FIXED BED agent or catalyst; Can cause bed to stop up, shorten service cycle.Common cleaning dust method can not the possible reason of this type of effective elimination dust be that dust granules is less; Has bigger outer surface; These dust granules are easy to adsorb the weak organic matter of hydro carbons isopolarity in the waste gas, dust granules is become have hydrophobic particle.Since the hydrophobicity of particle, and absorption and washing solution is the aqueous solution, under surface tension effects, hydrophobic particle is difficult for being washed down in the entering wash solution, and major part is got back in the gas phase again behind the gas-liquid two-phase surface collision.The inventive method is destroyed the hydrophobicity on dust granules surface through in cleaning solution, adding cleaning agent, reduces to absorb the washing lotion surface tension, can dust granules be washed smoothly to absorb in the cleaning solution.In absorption and washing liquid, add additives such as alkaline matter and oxidant, can absorbing waste gas in part sulfide, reduce the load of subsequent treatment process, prolong service cycle.If sulfide concentration is lower in the waste gas, after cleaning dust, can directly discharge.

Through the present invention, can eliminate the odor pollution of sulfur compound, hydro carbons and dust, after handling through the present invention, purified gas can reach national relevant emission standards, and purification efficiency is high, and the device periphery of loss stench can be eliminated odor pollution fully.
