Arsenic is a highly toxic pollutant that is widely present in raw materials and emission systems in fields such as petrochemicals, metallurgy, and environmental protection. Even a small amount of arsenic can cause catalyst poisoning, equipment corrosion, and environmental exceedances, seriously threatening production safety and ecological health. The arsenic removal agent, as a specialized functional material for targeted arsenic removal, has become a core necessity for industrial purification and environmental governance.
I. Why Remove Arsenic? How Harmful Is Arsenic?
- Poisoning Catalysts: In the production of polypropylene and ethylene, trace amounts of arsenic in raw materials can quickly poison precious metal catalysts, significantly reducing activity and lifespan, and directly raising production costs.
- Polluting the Environment: After the emission of arsenic-containing wastewater and exhaust gas, it will pollute water bodies, soil, and the atmosphere. Through the food chain, it can accumulate over time and cause skin damage, internal organ diseases, and even cancer.
- Corroding Equipment: Arsenic and its compounds will erode reactors, pipelines, and other devices, shortening the service life of equipment and increasing safety hazards.
China and international environmental protection standards have extremely strict control over arsenic content. Efficient and stable arsenic removal is the bottom-line requirement for compliant production in the chemical and environmental protection industries.
II. What is the Arsenic Removal Agent?
The arsenic removal agent is a specialized purification material with adsorption as its core mechanism. It loads active components onto a carrier to have a strong affinity for arsenic, fixing arsenic ions on the surface of the material to achieve deep arsenic removal from raw materials or fluids.
III. What Core Advantages Does a High-Quality Arsenic Removal Agent Have?
1. High Arsenic Removal Rate: Targeted adsorption of arsenic, without affecting the main components of the raw materials, with stable accuracy rate of purification.
2. Large Adsorption Capacity: One ton of catalyst can handle more materials, extending the replacement cycle and reducing operating costs.
3. Good Mechanical Strength: Resistant to impact and wear, strong bed layer stability, suitable for long-term continuous production.
4. Wide Operating Adaptability: Can cope with arsenic-containing systems of different concentrations and phases (gas/liquid), with stable performance in complex environments.
The RAs978 arsenic removal agent, RAs988 arsenic removal agent, and RAs998 arsenic removal agent produced by Shandong Xunda Chemical Industrial Group Co., Ltd. are mainly used for arsenic removal from raw materials such as propylene and ethylene, featuring good arsenic removal effect, large arsenic removal capacity, and convenient use, and their comprehensive performance has reached the level of imported catalysts.
Arsenic Removal Principle:
3CuO+2AsH3→Cu3As+As+3H2O
3CuO+2AsH3→3Cu+2As+3H2O
The arsenic removal agent is the invisible guardian in chemical production and environmental pollution control. It efficiently, stably and at a low cost resolves the problem of arsenic pollution, safeguarding the safety of the industrial chain and the ecological environment. With the increasingly strict environmental protection standards and the development of high-end chemicals, high-performance and customized arsenic removal agents will continue to be upgraded, providing key support for the green and low-carbon transformation of the industrial sector.
