Description
Technical field
The invention belongs to industrial waste gas processing technology field, it is related to a kind of Acidic Gas Treating and generates product reusing integral
Group technology.
Background technology
Requirement of the country for environmental protection at present is higher and higher, will be also increasingly stringenter to the control of pollutant discharge amount, sulphur,
The pollutant that two kinds of elements of nitrogen are formed has to reach the relevant discharge standard of country, thus the processing of two kinds of sulphur, nitrogen elements and
Recycling gradually obtains the attention of enterprise, recycles H in sour gas at present2The main technique of S has：Using Claus+SCOT methods as representative
The Dry recovery technique for producing sulphur, withLip river Kate method+product purification is the hydrometallurgic recovery for producing sulphur of representative
Technique, using ATP/SOP as the extracting sulfuric acid of representative/thiamine recovery technique.Deamination technology generally uses sewage stripping survey line to take out
Ammonia technology prepares ammonium hydroxide, or prepares ammonium salt using the pickling of sour gas containing ammonia technology.
Since this century the '30s improvement Claus methods realize industrialization, with H2S sour gas is that the sulphur of raw material returns
It receives process units to be rapidly developed, exploited especially since eighties of last century the fifties and Sulfur-Containing Crude and natural
Gas industrially generally uses elementary sulfur in Claus+SCOT recycling sour gas, the basic principle of Claus method sulfur recovery technologies
It is：Use partial combustion process by the H of one third at high-temperature region (burner for producing sulfur)2S burns into SO2, then remaining H2S and
Burn the SO generated2Reaction generates elementary sulfur.In order to improve sulfur recovery rate then again through low temperature conversion device, in the effect of catalyst
Lower H2S and SO2Continue Claus reactions and generates sulphur.
Lip river Kate's sulfur recovery technology belongs to wet processing, can be used to handle the gas that any type contains hydrogen sulfide
Body, low to the concentration of hydrogen sulfide requirement in sour gas, device operating flexibility is big, is adapted to raw gas flow and sulfide concentration
It is fluctuated in wide range.Lip river Kate's sulfur recovery technology basic principle is to use iron ion complex compound liquid catalyst
Agent, at normal temperatures by H2S is directly translated into elementary sulfur.Meanwhile iron ion catalyst is reduced into ferrous ion, used catalysis
Agent recycles after being regenerated with air oxidation.
ATP sour gas Sulphuric acid ammoniums are the patented technologies of Austrian PP companies, using its SOP sour gas process for preparing sulfuric acid as base
This, sour gas relieving haperacidity is combined finally with sour gas pickling Sulphuric acid ammonium by H in sour gas2S and NH3It recycles completely, most
Acidic Gas Treating obtains the production technology of ammonium sulfate at last, and SOP techniques are wide in range to the concentration of hydrogen sulfide requirement of air inlet, can be from percentage
Zero it is several to 90 or more percent, device operating flexibility is big, be adapted to raw gas flow and sulfide concentration larger
Fluctuation in range.SOP technique basic principles are that all element sulphur oxidations in sour gas are converted to SO by burning2, reaction equation
For：H2S+3/2O2→SO2+H2O.Then pass through reactor, under the action of catalyst by SO2It is converted to SO3, contain SO3Reaction
Object is sent to the condensation of glass tube condenser and generates sulfuric acid, and reaction equation is：SO3+H2O→H2SO4。
The above process chart is as shown in Figure of description Fig. 1.
At present in commercial plant element sulphur primary product, be generally divided into the hydrogen sulfide and acid water in low point of gas
Hydrogen sulfide, wherein with the formal adjoint of ammonia, general tupe is hydrogen sulfide containing raw material gas water to nitrogen, is filled through industry
Generation sour gas fed downstream device carries out sulphur or sulfuric acid processed after setting processing respectively.The long flow path handled in this way, energy consumption is high, holds
Easily form recontamination.
Invention content
In view of the problems of the existing technology, a kind of Acidic Gas Treating of present invention offer and generation product reusing integral group
Technique is closed, acid water is directly produced purified water and sour gas containing ammonia by the present invention by common process, and low point of gas passes through conventional work
Skill, directly production low point of gas of purification and the sour gas containing a small amount of ammonia；2 strands of sour gas are introduced into pickling in deammoniation tower, bottom of tower generates
Ammonium sulfate, then prepares solid ammonium sulfate, and tower top output purification sour gas prepares sulfuric acid, and the sulfate moieties re-injection generated
Deammoniation tower carries out the group technology of pickling, and the present invention prepares from raw material, generates target product, product reuse carries out integrated system
It closes, forms a set of Association Technology Devices, while energy-saving and emission-reduction, can also reduce plant investment and installation area.
The Acidic Gas Treating of the present invention and generation product reusing integral group technology, follow the steps below：

After coming, send to deammoniation tower；
(2) the raw material acid water of sewage stripping unit is detached ammonia and hydrogen sulfide by common process from acid water
After out, send to deammoniation tower；
(3) sewage stripping list in low point of desulfurization unit in step (1) generates sour gas containing ammonia and step (2)
The sour gas containing ammonia that member generates enters deammoniation tower after merging；After the sour gas containing ammonia that upstream is come enters deammoniation tower, through on deammoniation tower
Sulfuric acid under portion's spray carries out pickling, removes the ammonia in sour gas, and deammoniation tower lower liquid is the ammonium sulfate that reaction generates,
Tower top is the deamination sour gas after pickling, and the sour gas after deamination enters incinerator burning, and the gas after burning enters Sulphuric acid
System response generates sulfuric acid, and the sulfuric acid re-injection of generation returns deammoniation tower and carries out pickling, and extra sulfuric acid carrying device forms sour gas
It handles, the integration of product reuse.
Wherein, the deammoniation tower be carbon steel+316L liner forms, homogenous material form for example dual phase steel, fiberglass,
PTFE, carbon steel+other liner forms, as carbon steel inner lining glass fiber reinforced plastic, carbon steel liner PTFE or itself or other materials add other linings
Form, such as 316L inner lining glass fiber reinforced plastics, two-phase steel lining PTFE；There is partition board in tower reactor, is separated out circulation fluid up and down, the tower reactor
Internal partition can be cancelled, and return tank is separately provided outside tower to change deammoniation tower form.
Compared with prior art, the features of the present invention and advantageous effect are：
The key position formed a connecting link in the present invention is deammoniation tower, and in the process of running, Acidic Gas Treating is qualified, product sulphur
Acid, which generates, to be stablized, sulfuric acid re-injection deamination operational excellence, and economic benefit is relatively high.
