Solution Overview
Problem
Existing wireless communication systems fail to address the challenges of existing wireless communication systems fail to efficiently remove elemental and oxidized mercury from waste liquid, with activated carbon injection technology being costly and its mercury removal efficiency is affected by NOx and SO2.
Innovation Solution
Utilization of metal sulfides (e.g., FeS2, CuS, CuS, CuFeS2) as mercury removal adsorbents, which contact with flue gas and waste liquid, adsorbing and converting Hg0 from flue gas and oxidized mercury from waste liquid into stable mercury sulfide compounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If activated carbon injection technology is used for mercury removal, then mercury removal capacity is improved, but operational cost increases
Solution Approach 1:
The patent replaces expensive activated carbon with cheap metal sulfide particles that can be injected directly into the flue gas stream. These metal sulfide particles serve as disposable adsorbents that react with mercury to form stable sulfide compounds, providing effective mercury removal at lower operational costs.
Solution Approach 2:
The patent changes the chemical composition parameter of the adsorbent material from activated carbon to metal sulfides (such as FeS2, CuS, CuFeS2). This parameter change fundamentally alters the removal mechanism from physical adsorption to chemical reaction, improving both effectiveness and cost-efficiency for simultaneous removal of Hg0 and Hg2+.
2Reliability
If activated carbon injection is used, then mercury removal is achieved, but removal efficiency is affected by NOx and SO2 interference
Solution Approach 1:
The patent changes the chemical reactivity parameters of the adsorbent by using metal sulfides instead of activated carbon. Metal sulfides selectively react with mercury species (Hg0 and Hg2+) through chemical reactions to form stable mercury sulfide compounds, while showing reduced sensitivity to interference from NOx and SO2 present in the flue gas and waste liquid.
Solution Approach 2:
The patent converts the potentially harmful interaction between adsorbents and flue gas components into a beneficial selective reaction. Metal sulfides preferentially react with mercury species even in the presence of NOx and SO2, effectively converting the complex flue gas environment from a source of interference to a condition where selective mercury removal can proceed.
