Description
Technical field
Patent of the present invention belongs to field of Environment Protection, is related to the process of sulfur-containing waste water and sulfurous gas it is adaptable to chemical industry, especially
It is applied to the industry that crude benzole hydrogenation, gasoline and diesel hydrogenation, heavy-oil hydrogenation etc. have sulfur-containing waste water and sulphur-containing exhaust gas simultaneously.
Background technology
With industrial expansion, sulfur dioxide causes atmospheric pollution and its harm, has been increasingly becoming environment of concern
Problem, hydrogen sulfide is colourless gas, has strong rotten egg abnormal smells from the patient, hydrogen sulfide gas have combustibility and explosivity, blast
Lower limit is 4%, and the upper limit is 45.5%, and this gas is a kind of never poison, also for asphyxiating and irritative gass, the maincenter to people
Nerve and the organ such as respiratory system and heart have the position of infringement, especially brain and mucosal contact, have serious danger to human body
Evil property.Therefore, control the discharge of sulfur dioxide, for controlling atmospheric pollution, improve the ecological environment and have very important meaning.
The process of gaseous sulfur dioxide, typically using two kinds of processing methods of dry and wet:
Dry desulfurization process is most to belong to gas-solid reaction, and relatively lower speed, flue gas flow velocity in the reactor is slower,
Response time is long, therefore equipment is huger, but the flue gas cool-down after desulfurization is less or does not lower the temperature, therefore is not required to heat (power consumption is few) again,
Discharge diffusion can be met require.Additionally, secondary pollution is few, no fouling, blocking, reliability is high.
Dry desulfurization typically processes the less gas sweetening of sulfur content it is adaptable to fine de-sulfur.
Its basic process of wet method is to wash flue gas with desulfuration solution, and mass-transfer progress is general fast compared with gas-solid, equipment
Relatively small, efficiency higher (90%), reliable.Major defect is；Complex process, floor space is big, and investment cost is high, only
Cigarette temperature after change is relatively low, and it need to be heated again, spreads with after profit discharge.
Wet desulphurization is mainly different according to product, and from different methods, conventional has limestone or Calx washing method
(lw), the method is most of generates sub- gypsum solid, is generally individually oxidized to Gypsum Fibrosum, can abandon as waste residue, also recyclable
Gypsum Fibrosum, because its desulfurizing agent is cheap and easy to get, therefore application is very wide, changes hands into hard scale with pipe content in reactor, produces a large amount of simultaneously
Waste residue, environmental protection impact yet suffers from.Sodium sulfite circulates washing method, obtains concentration sulfur dioxide gas, and compressible one-tenth price is higher
Sulfur dioxide liquid, may be made as sulphuric acid or sulfur product, desulfurization degree 95%.This method shortcoming is: investment is big, and operating cost is relatively
High (alkaline consumption is high), due to the generation of sulphite in system, the thing followed is the reduction of ph value and corrodes aggravation it is adaptable to have
The area of alkali source adopts；Catalytic desulfurization antacid may also be employed, that is, utilize activated carbon adsorption by under the sulfur dioxide removal in relation by marriage gas
Come, then generate dilute sulfuric acid with steam reaction.But the process of dilute sulfuric acid is also a big problem.Existing industrial be most frequently with de-
Sulfur method is Crouse's doctor treatment, the method technical maturity, and product is sulfur, can be directly as production marketing.But the method
Equipment investment is big, the process of the sulfurous gas of suitable atm number.
The industries such as oil refining, petrochemical industry, pharmacy, fuel and process hides all can produce substantial amounts of sulfur-containing waste water in producing kind, gives up
Sulfide in water is toxic, corrosivity, and has stink, environment is caused greatly pollute, and can be to waste water structures
Normal operation produces a very large impact, therefore produce, life in sulfur-containing waste water must be dealt carefully with.
In the waste water that different industries are discharged, sulfur content and component differ greatly, so processing method is also different, from from
Divide in reason method, be broadly divided into physical chemistry and process and biochemical processing method two big class, the main technique adopting mainly has: chlorination
Method, neutralisation, aeration, oxidizing process, the sedimentation method, vaporizing extract process, electrochemical oxidation process, supercritical water oxidation method, resin method etc. are several
Big technique.
Refine industry and hydrogenation industry in petrochemical industry, it is different to be typically based on unit scale, the sulfur-containing waste water producing and
The amount of sulfurous gas is also different, is hydrogenated with industry on a large scale, and the sour gas scale of construction is big, typically adopts Claus method and absorbs oxidation
Method, wherein with Recovered sulphur as major technique, but the investment of Clause method sulfur production sulphur is big, and output is low, and operating cost is high, adds sulfur
Sulphur price is gradually reduced, and profit is low, and Claus method desulfurization applies in general to the process of atm number sulfurous gas, and little tolerance contains
Sulfur gas cannot adopt this method, and the process Dou Ling producer of the sulfur-containing tail gas of small-scale device extremely has a headache all the time；Contain
Hydrogen sulfide is then proposed by sulfur waste water using vaporizing extract process, then adopts the alkali liquor absorption hydrogen sulfide such as lime water, ultimately generates nuisanceless
Gypsum Fibrosum.
