Mercury adsorbent

Achieving reliable removal of gaseous mercury and long lifespan.

Our company manufactures and provides a specialized mercury adsorbent that efficiently adsorbs and removes gaseous mercury contained in exhaust gases. In addition to the conventional lead sulfide (PbS) based adsorbents with proven track records, we have recently developed a new type of adsorbent that uses copper sulfide (CuS) as the adsorbing component, allowing us to offer optimal proposals tailored to various applications and requests. This adsorbent achieves a very high mercury removal rate of 95-98% under operating conditions of an adsorbent layer thickness of 1,500mm and a gas flow rate of approximately 0.2m/s. This high performance is due to the adsorbent's high reactivity and uniform component distribution, making it suitable for a wide range of exhaust gas treatment sites, including various factories and power plants. Moreover, unlike activated carbon-based adsorbents, there is no decrease in removal performance due to moisture in the exhaust gas, allowing for stable high efficiency to be maintained over long periods. Additionally, its performance is less likely to be compromised in environments where sulfur dioxide (SO₂) gas coexists, with expected long operational lifetimes ranging from several years to a maximum of about 10 years. 【Features】 ■ High removal efficiency ■ Low pressure loss ■ Long lifespan ■ Contains almost no Pb (lead) in the adsorbent *For more details, please download the PDF or feel free to contact us.
