Hydrogen Sulfide Explosion Factors
On hydrogen sulfide explosion
If hydrogen sulfide is used, the gas is highly toxic and explosive. The risk of its explosion is related to all things and cannot be ignored.
Factors of hydrogen sulfide explosion
Concentration
Hydrogen sulfide is in the air, and its concentration reaches a certain range, before there is a risk of explosion. When it is within the explosion limit range, it is easy to explode when encountering ignition sources. If in a closed place, hydrogen sulfide accumulates but does not disperse, and the concentration gradually rises, reaching the lower limit of about 4.0% and the upper limit of about 46.0%, when it is exposed to open flames, static electricity, etc., it will explode suddenly, and it will be like thunder. The destruction will hurt people, which is a serious disaster.
Danger of ignition source
The ignition source is the fuse of hydrogen sulfide explosion. Open flames, such as unextinguished cigarette butts and welding fires, can instantly explode hydrogen sulfide. Static electricity is also not to be underestimated. When materials are transported and gas flows, static electricity is generated due to friction. If it cannot be removed in time, the charge will accumulate. Once discharged, the energy will be enough to cause hydrogen sulfide to explode. Electrical equipment failures, such as short circuits and overloads causing electric sparks, are also potential sources of ignition, causing the risk of explosion.
Balance of oxygen content
An appropriate amount of oxygen is necessary for the combustion and explosion of hydrogen sulfide. Although hydrogen sulfide does not require a large amount of oxygen for combustion and explosion, the normal oxygen content in the air is about 21%. If the oxygen content in the environment is suitable, hydrogen sulfide and oxygen are mixed to form a combustible mixture. If the oxygen content is too low, the combustion cannot be sufficient, and the explosive power may be reduced; if it is too high, the reaction will be more violent and the explosion hazard will be even greater.
Danger of confined space
In confined space, such as mines, storage tanks, sewers, etc., once hydrogen sulfide leaks, it is not easy to spread. In a limited space, the concentration rises rapidly, and if the ignition source exists, the explosion is very easy to occur. Space is limited, and the pressure wave generated by the explosion has no way to vent, and the destructive power is doubled. The surrounding structure and personnel are
Strategies to prevent hydrogen sulfide explosions
To avoid the scourge of hydrogen sulfide explosions, multiple measures should be taken. At the source, strengthen monitoring, and set up a sensitive hydrogen sulfide monitor to know its concentration in real time. The workplace must be well ventilated, with strong ventilation devices to disperse hydrogen sulfide so that its concentration is far below the explosion limit. Strict control of ignition sources, no open flames are allowed to enter dangerous areas, equipment is well grounded, and static electricity is accumulated. Regular inspection of electrical equipment to ensure its safe operation. Operating in confined spaces, ventilate and replace first, measure the oxygen content and hydrogen sulfide concentration, confirm safety before entering, and set up special personnel to monitor.
In summary, the factors of hydrogen sulfide explosion can be effectively prevented in order to reduce its harm and ensure the safety of people and things.
