Desulfurization and deodorization filter "Corline" for removing corrosive gas hydrogen sulfide.

basic information

● Four Important Points About Hydrogen Sulfide 1. It has the potential to occur "anywhere" if conditions are right. It can occur not only in hot spring areas, landfill sites, wastewater treatment plants, laboratories, sewage treatment facilities, cleaning plants, and oil refineries, but also in other locations. 2. It can "naturally occur" if conditions are right. Hydrogen sulfide is naturally produced when organic compounds containing sulfur are reduced and decomposed by bacteria. Even in the presence of mold on ham that ends up on your dining table, a small amount of hydrogen sulfide is generated. 3. Effects of hydrogen sulfide on the human body. The danger of hydrogen sulfide lies in the fact that at certain concentrations, it can cause olfactory paralysis, leading to a "loss of smell." Even if there is no odor, the concentration can rise unnoticed, and prolonged exposure can lead to accidents. 4. Effects of hydrogen sulfide on electronic devices. Even in trace amounts, hydrogen sulfide can have corrosive and other adverse effects on all electronic devices, including computers, PLCs, and various measuring instruments. Additionally, as electronic circuit boards have become more densely packed in recent years, new electronic devices may fail due to the effects of hydrogen sulfide after being replaced. Concentration affecting electronic devices: from 0.003 ppm (which is significantly lower than the 0.02 ppm at which humans can detect odor).

Applications/Examples of results

● Metal Product Processing Factory (Water Treatment Facility) Sulfuric acid used for cleaning metals can generate high concentrations of hydrogen sulfide depending on the wastewater treatment conditions. To eliminate odors generated from the water treatment facility, a deodorization unit with a fan that sucks in gas is installed above the treatment facility to remove the unpleasant smells in the surrounding area. ● Chemical Processing Facility in the Factory (Wastewater Treatment Equipment) Used for the removal of hydrogen sulfide odors generated from the factory's chemical facilities, wastewater treatment equipment, and drainage pits, as well as for corrosion prevention of electronic devices. Equipment that processes sulfuric acid and other sulfur-rich chemicals used for cleaning can produce high concentrations of gas. Hydrogen sulfide can damage electronic devices in surrounding equipment and may adversely affect equipment in other buildings. ● All-Solid Battery Research Facility (Emergency Exhaust Equipment) In all-solid batteries (lithium-sulfur batteries), hydrogen sulfide may be generated if the cells are damaged. In research facilities, there are tests that intentionally damage cells to confirm safety, and the hydrogen sulfide generated there is removed and safely discharged outdoors. ● Food Factory (Manufacturing Equipment) Many foods contain "sulfur," and hydrogen sulfide can be generated depending on the processing conditions. The hydrogen sulfide and odors generated during the food manufacturing process (equipment) are removed using a desulfurization and deodorization filter called "Coraline," which is utilized for exhaust to prevent pollution.
