Taking the zinc smelting plant as example, the flue gases are initially absorbed by the ZnO pulp, followed by deep desulfurization using the NaOH solution or CaO pulp (Hanif et al. 2020; Shi et al. 2021). However, the cost of NaOH is high up to 15% of zinc metal (the main product in zinc smelting plant), greatly weakening the profit margin.
