In nature, hydrogen sulphide is a colourless chalcogenic hydride gas with an unpleasant aroma akin to rotten eggs. The gas poses a threat to the environment and the general public’s health and is poisonous by nature. When exposed for a long time to high levels, this hazardous gas can cause shock, coma, and death in addition to causing eye, nose, and throat irritation, headaches, and dizziness. The typical sources are animal and human waste, wastewater treatment facilities, crude oil, volcanic eruptions, and hot springs.

Technology We Use

What technology is being used in H2S Sensor?

One of the most popular techniques for estimating the amount of H2S in the atmosphere is the electrochemical method of monitoring. This approach involves feeding a sensor containing electrodes—a working electrode, a counter electrode, and an ion conductor—a sample of air.

H2S interacts with the electrolyte and is oxidised, producing ions and water molecules. The amount of current generated by these ions in the sensor is exactly proportional to the amount of hydrogen sulphide present in the surrounding air.

H2S Sensor Calibration

Calibration involves comparing your instrument or device measurement to the actual/standard measurement. The precision of the apparatus and the traceability of the measurements can both be ascertained through calibration. For accurate calibration, the sensor is exposed to H2S in the desired range. The target gas is referenced using the NIST standard gas cylinder. The typical ambient parameters utilised for sensor calibration are: 23 + 3 °C temperature, 50 + 15% relative humidity, 0.9-1.1 atm pressure, and 0.05 m/s air velocity. The sensitivity of the sensor may change when the environment changes, although this can be easily remedied.

About Hydrogen Sulfide (H2S) Gas

When organic substances break down without oxygen, a chemical called hydrogen sulphide is created. Additionally, this gas can be found in volcanoes, oil drilling operations, and sewers. This gas has a foul smell and is toxic and corrosive. H2S and air have a strong explosive potential. Before changing into other oxides, it hangs around in the atmosphere for a few hours.

Major sources of H2S are naturally occurring:

– It is found during oil extraction and operation
– Sewers have a high concentration of H2S due to anaerobic reactions.
– Solid organic compounds containing sulfur reacting with oxygen.
– There is a high concentration of H2S in wastewater treatment plants.
– Volcanos are also a major source of H2S.

Although it is possible to eliminate H2S from the environment, these methods are only used in experimental research and are not practical. The only reliable method for detecting the gas for any preventative and corrective actions is monitoring. We can only prevent interaction with this dangerous gas by taking preventative and corrective measures.

Some corrective measures to prevent and avoid the gas:

– Avoid open disposal animal waste
– Avoid open sewers as there can be a high concentration of H2S.
– Proper ventilation for the area where you detect the gas.
– Gas masks when exposed.

Health & Environment Impact of H2S Gas

Get to know the effects of hydrogen sulfide gas to our health.

H2S is a foul-smelling gas that has a very negative impact on the human body and, in severe cases, can even cause death. When exposed to the gas at high levels, it results in the following symptoms:

– Affects the person’s ability to sense smell

– Eyes, nose and throat irritation

– Breathing difficulties

– Shock, convulsions

– Coughing, dizziness, nausea

– Headache, coma, death

One of the key substances in charge of causing acid rain is H2S. Sulfuric acid is created as a result of the reaction with airborne water molecules. Additionally, it is a strong corrosive agent that destroys metal structures and shortens their lifespans, which costs the government money.

Environmental Impacts:

– Increases the chances of leakage of other harmful gases in environment

– Persists for longer duration in environment

– Convertible to sulfur dioxide and sulfuric acid

– Induces toxicity in plants at high levels

– Inhibits growth of plants

– Affects vegetation, constructed building, agriculture

Frequently Asked Questions
(FAQs)

1. Will this H2S sensor come along with a digital board or not?

A digital board is not included with the sensor, however one should be purchased separately if one is required. A USB microcontroller and a digital board are provided by Prana Air; both must be connected.

2. What conditions are used for calibration?

The typical ambient parameters utilised for sensor calibration are: 23 + 3 °C temperature, 50 + 15% relative humidity, 0.9-1.1 atm pressure, and 0.05 m/s air velocity. Although the sensitivity of the sensor may change due to changes in the environment, this is easily remedied.

3. What is the warranty period of H2S sensor?

Prana Air only offers a 6-month warranty on manufacturing flaws.

4. What connectivity is used in H2S sensor?

A digital board and a USB microcontroller are additional features of Prana Air. The USB to UART Bridge is linked to the H2S sensor by the DGS.

5. How dangerous is hydrogen sulfide?

According to OSHA regulations, the peak limit for the general industry is 50 ppm, and the personal exposure limit for that sector is 20 ppm. In extreme circumstances, the level of gas can rise up to 2000 ppm. Conjunctivitis, nausea, teary eyes, coughing, loss of smell, and high exposure levels of 1000–2000 can result in almost instantaneous death. The gas is combustible by nature and has the ability to start a fire, which might be fatal.

6. How do I know I am at high risk of exposure?

High risk exists for those who live close to open gutters, drains, sewers, and channels. Additionally, there is a substantial risk of exposure for those who work in the mining, agriculture, textile, paper, and pulp manufacturing, sewer and wastewater treatment, and sanitation sectors.

7. What symptoms will I feel if I am exposed to hydrogen sulfide?

The degree of exposure affects the symptoms of exposure. Acute (shorter-duration) exposure to hydrogen sulphide can cause symptoms like nausea, skin and eye irritation, headaches, and convulsions. Chronic (longer-lasting) exposure causes extremely quick sleepiness, cutaneous frostbite injury, and in some cases, even death.

8. What measures can I take to protect myself from hydrogen Sulfide?

Use of Prana monitors continuously Having H2S sensors will enable you to recognise when this gas is present in a dangerous level, allowing you to take precautions like avoiding areas where H2S emissions are known to occur, closing the windows of your home whenever the level increases or an odour is noticed, donning gas masks, and avoiding visiting nearby sewage and waste treatment facilities. Installing engineering controls in workplaces, however, is the most effective way to prevent H2S exposure.
