Description

The device of process molten sulfur pond tail gas and the processing method of molten sulfur pond tail gas

Technical field

The invention belongs to petrochemical industry and field of Environment Protection, specifically, the invention provides and a kind ofly process the device of molten sulfur pond tail gas and the processing method of a kind of molten sulfur pond tail gas.

Background technology

China advocates energy-saving and emission-reduction work always, requires strict control sulfur dioxide in air discharge capacity.National departments concerned is fermenting revision discharge standard of air pollutants, requires that newly-built sulphur unit sulfur dioxide emissioning concentration is less than 400mg/Nm 3(even require that some areas concentration of emission is less than 200mg/Nm 3).Sinopec is just actively pushing forward green low-carbon development strategy, reduction sulphur unit SO 2 from fume concentration of emission is striven for one of world-class important indicator as oil refining plate, requires that sulfur dioxide emissioning concentration in 2015 reaches world-class levels (400mg/Nm 3), Some Enterprises reaches world lead level (200mg/Nm 3).With world lead level (200mg/Nm 3) corresponding to, the Hydrogen Sulfide Tail Gas content entering incinerator after requiring Crouse's tail gas of sulphur to purify must be less than 50mg/Nm 3, existing Crouse's tail gas of sulphur treating apparatus all can not reach, and must develop new technology or increase new first grade desulfurizing device, this will cause energy consumption high, and investment is large.

For the process of the molten sulfur pond tail gas of Crouse's sulphur recovery unit, original method is directly imported in water scrubber by tail gas, after washing, go incinerator to burn then emptying, such processing method causes absorption tower very easily to block, substantially every 2-3 month device and pipeline just there will be blocking, and the tail gas sulfur content after process exceeds standard, and causes environmental pollution.

And other are for the exploitation of hydrogen sulfide-containing tail gas treatment technology, the feature do not related to for molten sulfur pond tail gas processes especially.As disclosed a kind of sulphur recovery and exhaust gas processing device and method thereof in CN100544807C, be characterized in that this device has thermal response section, catalyst reaction section and Reducing and absorption section, there is certain desulfurized effect, to desulfurization treatment system, there is applicability widely, reduce the amounts of hydrogen needed for tail gas hydrogenation, thus reduce the risk of sulfur dioxide (SO2) emissions.

For another example, a kind of method simultaneously removing hydrogen sulfide and sulfur dioxide is disclosed in CN100473448C, make to contact with water or containing the aqueous solution for the first different-phase catalyst of desulfurization with the gas of sulfur dioxide containing hydrogen sulfide, to utilize sulfur dioxide to carry out oxidation of sulfureted hydrogen, process is to a certain extent carried out to the hydrogen sulfide in tail gas and sulfur dioxide.

For another example, a kind of method removing hydrogen sulfide from hydrogen sulfide-containing tail gas is provided in CN102019141A.Technical process of the present invention: the 1. preparation of catalyst; 2. the catalyzing, oxidizing and purifying technique that in hydrogen sulfide-containing tail gas, the process for purifying process of hydrogen sulfide or hydrogen sulfide absorption and oxidation substep carry out.Hydrogen sulfide is oxidized to elemental sulfur and realizes resource, also can solve the pollution problem of hydrogen sulfide to a certain extent.

Obviously, disclosed said method does not all consider the feature of molten sulfur pond tail gas, namely the molten sulfur wherein carried secretly drips, and molten sulfur drips not treated, easy blocking water scrubber column plates etc., cause device to stop work, and impact is produced, and will be discharged in air in the form of sulphur dioxide after burning, cause environmental pollution.In addition, also there is the problems such as series of problems such as equipment investment is large, maintenance cost is high, the consumption of amine liquid is many, tail gas sulfur-bearing is high in these methods, along with China is to the further attention of environmental problem, to the further raising that sulfur dioxide in air discharge capacity requires, new molten sulfur pond tail-gas deep high-efficiency desulfurization technology is adopted to be trend of the times.
