Hydrogen sulfide gas countermeasure 'Koro Shooter' from pulp and waste paper processing
Koro Shooter
One-time removal of hydrogen sulfide gas generated from the sulfuric acid treatment and wastewater treatment facilities of recycled paper, board, and cardboard manufacturing plants. Protects control equipment from hydrogen sulfide gas.
Hydrogen sulfide gas is a highly corrosive and harmful gas. Exposure to hydrogen sulfide gas can cause corrosion (rust) on the copper and silver parts of equipment, leading to equipment failure. The Coro Shooter removes hydrogen sulfide gas and prevents equipment failure due to corrosion. Hydrogen sulfide gas is generated in sulfuric acid treatment and wastewater treatment facilities at recycling, paperboard, and cardboard manufacturing plants. Even trace amounts of hydrogen sulfide gas that do not affect human health can have a significant impact on equipment. Hydrogen sulfide gas at levels of just a few tens of ppb can cause equipment failure due to corrosion. By installing the Coro Shooter inside the control panel where the equipment is housed, you can purify the air inside the panel and prevent equipment failure caused by hydrogen sulfide gas. Since it can be installed directly in the panel, it is a simple and low-cost solution for addressing hydrogen sulfide gas. ＊＊＊＊Exhibition Information＊＊＊＊ We will be exhibiting at the Sewerage Exhibition 25 in Osaka. Event Period: 2025/7/29-8/1 Booth Number: 2-317

basic information
The Koro Shooter employs a chemical adsorption method that uses chemical adsorbents to react with and eliminate hydrogen sulfide gas. Unlike physical adsorption, which attaches hydrogen sulfide gas like activated carbon, the chemical adsorption method transforms hydrogen sulfide gas into a different substance, eliminating concerns about gas re-release. Additionally, compared to photocatalytic methods, the adsorption speed is 5 to 10 times faster, resulting in a very high removal efficiency, allowing for the immediate removal of incoming hydrogen sulfide gas. The rapid removal speed minimizes the risk to equipment.

Applications/Examples of results
The hydrogen sulfide gas generated by the sulfuric acid treatment and wastewater treatment facilities in recycling paper, board, and cardboard manufacturing plants is removed to protect the surrounding equipment from corrosion failures caused by hydrogen sulfide gas. In some cases, a coating is applied to the base of the equipment as a gas countermeasure, but the coating cannot be applied to the connector parts. Unless the hydrogen sulfide gas is removed, it is impossible to prevent corrosion failures caused by hydrogen sulfide gas. Additionally, coating processing is costly and takes a long time, making it difficult to procure replacement equipment immediately if a failure occurs. Furthermore, due to the recent semiconductor shortage, inverters and relay switches that are vulnerable to hydrogen sulfide gas are experiencing long lead times, making it challenging to procure replacement parts if the machinery fails. By installing a corrosion shooter, it contributes to the safe operation of the factory and enables the reduction of opportunity losses due to equipment failures. It is being adopted in paper mills across the country.
