AI Technical Summary
Existing ammonia-based desulfurization processes face challenges in controlling ammonia leakage and aerosol generation during absorption, leading to inefficient desulfurization, high energy consumption, and increased operational costs due to the interdependence of absorption, oxidation, and concentration processes, with current methods focusing on post-treatment rather than source control.
A method and apparatus that control aerosol generation by phase-wise solution composition and reaction conditions, including controlling oxygen and water content, absorption temperature, and using multiple phases of ammonium sulfite and sulfate solutions to coordinate absorption, oxidation, and concentration, reducing the need for post-treatment methods like wet electricity and multi-phase water washing.
Achieves high-efficiency desulfurization and dedusting while minimizing ammonia leakage and aerosol generation, reducing energy consumption, and simplifying the process flow, thereby meeting stringent emission standards and lowering operational costs.
