Description
Technical field
The invention belongs to oil equipment field, and in particular to a kind of integrated device based on triazine solution desulfurization and
Method, specifically a kind of hydrogen sulfide used applied to gas field well site and yard in triazine solution removal natural gas（H2S）
Triazine solution desulfurization automatic cycle, fluid infusion integrated device and method.
Background technology
If contain H from the natural gas of stratum extraction2S, not only can cause to corrode, can also bring environment to equipment and pipeline
Pollution, it is therefore necessary to remove H2S.According to the number of contained element sulphur quality in natural gas, the desulfurization process of natural gas can be advised
Mould is divided into low latent sulfur content（Elementary sulfur less than 0.1t/d）, in dive sulfur content（The elementary sulfur of 0.1~30t/d）With the latent sulfur content of height
（Elementary sulfur higher than 30t/d）Scale.
Purification for low latent sulfur content natural gas, domestic generally use ferric oxide solid dry desulfurizing process.The technique
Desulfurization principle is that with hydrogen sulfide chemical reaction generation Fe2S3, chemical equation Fe occur for solid oxidation iron2O3+3H2S→
Fe2S3+3H2O, this processing mode needs to carry out blocked operation using two desulfurizing towers, when a desulfurizing tower reaches saturation,
Another desulfurizing tower must be switched to and carry out desulfurization, while desulfurizing agent must also be replaced, thus this mode operates again
It is miscellaneous, time-consuming and laborious, and since spontaneous combustion easily occurring after waste desulfurizing agent and air contact, waste desulfurizing agent recycling difficulty is big.
External generally use liquid sulfur removal technology carries out purified treatment to low latent sulfur content natural gas, only just has in north America region
More than 1000 set liquid desulfurizers put into operation.Liquid desulfurizing agent is a kind of emerging sulfur elimination, and foreign applications are relatively broad, but state
Interior experiment just starts, its is of low cost, desulfurization is rapid, Sulfur capacity rate is high, using convenience, both can be natural with sulfur-bearing in retort
Moment reaction occurs for gas, can also inject collection feed channel, reach the effect of moment desulfurization.Liquid sulfur removal technology is to use triazines
The aqueous solution and H of compound2Irreversible chemical reaction generation thiadiazine occurs for S, so as to reach H in removing natural gas2The purpose of S.
Since the desulfurization product generated is water-soluble liquid, therefore its is safe, and waste desulfurizing agent easily recycles.Triazine takes off
Sulphur principle:Triazine belongs to a kind of cyclic amine, is provided simultaneously with the essential characteristic of amine.PH is usually 10~11.Nitrogen-atoms is strong on ring
Electron attraction cause the carbon on triazine ring that there is electrophilic property.When nitrogen-atoms protonates, carbon atom on meeting reinforcing ring
Electrophilicity, promotes piperazine to strengthen the nucleophillic attack reactivity of hydrogen sulfide and other nucleopilic reagents.These structural properties make 1,3,5
One or three (2- ethoxys) perhydro-s-triazines become good hydrogen sulfide remover.

（1011）.
A kind of 10. application process of the integrated device based on triazine solution desulfurization, it is characterised in that：Sulfur-containing gas lead to
Cross defeated bypass line outside natural gas（202）It is directly entered exhaust line（3）It is outer defeated, or after blow-down pipe is vented, then through into
Gas pipeline（2）Into absorption tower（1）Interior, triazine solution is by desulfurizing agent entrance（103）Into absorption tower（1）It is interior, sulfur-containing gas
Counter current contacting, moment chemically react in tower with triazine solution, remove the hydrogen sulfide in sulfur-containing gas, purified day
Right gas is through exhaust line（3）It is outer defeated, open electric emergency block valve（601）, block valve one（602）, discharge opeing electric control valve
（603）, block valve two（604）, the waste liquid after sulfur-containing gas and triazine solution reaction is through blowdown pipeline（6）Discharge；
Triazine solution after reaction is exported through desulfurizing agent（104）Discharge is again by circulating pump（401）It is pumped into absorption tower（1）It is interior, carry out
Circular response, passes through online H2S detector（302）Set hydrogen sulfide content value, online H2S detector（302）
The hydrogen sulfide content of natural gas after detection purification, the automatic start fluid infusion pump when detecting that hydrogen sulfide content reaches setting value
（501）, while open discharge opeing electric control valve（603）, absorption tower is set by Fork LIquid Level Switch（1）Interior high liquid level and low
Liquid level, absorption tower（1）Interior triazine solution level closes discharge opeing electric control valve when being reduced to the low liquid level value of setting（603）, inhale
Receive tower（1）Interior triazine solution level closes fluid infusion pump when being increased to the high liquid level value of setting（501）.
