Description
Technical field
The invention belongs to petrochemical industry and field of Environment Protection, relate to the minimizing technology of a kind of high concentration hydrogen sulfide gas, be suitable for
In high concentration hydrogen sulfide gas removal process.Specifically, the invention provides high concentration hydrogen sulfide gas minimizing technology and
Device.
Background technology
H2S is a kind of colourless irritative gas, has strong rotten egg abnormal smells from the patient, polar molecule, and relative molecular mass is
34.08, odor threshold is about 0.00041ppm, relative density be 1.19(atmospheric density be 1), fusing point is-85.5 DEG C, boiling point
For-60.4 DEG C, soluble in water and ethanol.
Hydrogen sulfide is present in the production processes such as petrochemical industry, papermaking and weaving, and harm is relatively big, can cause equipment corrosion, meeting
The health of environment and human body is caused bigger harm.In the industrial production, hydrogen sulfide activity is very big, electrochemistry weight-loss corrosion,
Sulphide stress corrosion and hydrogen embrittlement can make pipeline cause strong corrosion, thus cause great security incident；Simultaneously as
Never poison, the cental system of human body or respiratory system can be brought irreversible infringement, calomel poisoning Symptoms by hydrogen sulfide
For photophobia, shed tears, eye twinge, watery nasal discharge, foreign body sensation, nasopharynx scorching hot, and with dizzy, headache and the symptom such as weak；Moderate intoxication
After can occur immediately giddy, headache, weak, Nausea and vomiting, shakiness of walking, cough, dyspnea, throat itch, chest compression
The symptoms such as sense, disturbance of consciousness, Eye irritation symptom is strong, have shed tears, photophobia, the sensation of eye twinge；May cause during severe intoxication
Take action the states such as blunt, confusion, stupor and pulmonary edema cerebral edema, finally dead because of respiratory paralysis.Hydrogen sulfide is toxicity
One of atmosphere pollution greatly, it is necessary to its discharge is strictly controlled." emission standard for odor pollutants " GB14554-
