Summary: MgO nanofluids show better desulfurization effect in wet desulfurization process compared to MgO slurry by improving desulfurization efficiency. The density and viscosity of MgO nanofluids increase with concentration, but decrease with temperature. Properly reducing particle size can enhance the desulfurization efficiency of MgO absorbent in removing SO2 from flue gas.

Summary: This study presents experimental and modeling results on the removal of SO2 and combustion particles in a pilot-scale wet electrostatic scrubber. The experiments showed that increasing the spray charge density improved the absorption efficiency of SO2, and further enhancement was achieved with corona pre-charging. Similarly, increasing the spray charge density and corona pre-charging potential improved the overall particle capture efficiency. The results accurately described the absorption of SO2 in certain configurations and the particle capture in another configuration, but further research is needed for other conditions.

Summary: This study investigates the use of a Wet-Oxidative Scrubber (WOS) for controlling both SO2 and NOx emissions from exhaust flue-gases. The results show that the WOS can simultaneously remove SO2 and NOx, and the presence of SO2 in the flue-gas enhances the oxidative mechanisms, leading to improved NOx removal efficiency. A predictive model based on experimental dosages of NaClO2 is developed to predict the performance of the WOS unit, including de-SOx and de-NOx efficiencies as well as wash water pH.

Summary: Coke oven gas is an important byproduct used as an energy substitute for natural gas in the steel industry, but it requires treatment to remove impurities like ammonia and hydrogen sulfide. Developing a more efficient absorption process is crucial due to the increasing use of coke oven gas and stricter emission regulations. A model was created to evaluate solutions for greater hydrogen sulfide removal, with the best configuration showing a 5% increase in efficiency. This aligns with efforts towards environmentally responsible solutions and also resulted in a 15% reduction in raw materials costs.

Summary: Exhaust gas from navigation is a significant contributor to air pollution, especially in coastal and port cities. The installation of a hybrid exhaust gas cleaning system (EGCS) has become popular for reducing SO2 emissions due to its flexibility and efficiency. This study developed a detailed model of hybrid EGCS to investigate the impacts of important factors on the SO2 absorption and crystallization processes. A comparison between seawater and magnesium-based absorbents in terms of SO2 absorption was conducted, highlighting the adaptability of magnesium-based absorbents to temperature and SO2 concentration. Additionally, the safe operating ranges of magnesium-based absorbents were studied to prevent scaling and ensure the safe operation of EGCS. An operation strategy for different absorbents was proposed to enable adjustments based on seawater temperature, pH, and emission standards, offering valuable insights for the design and operation of EGCS.
