Intensification of hydrogen sulfide absorption by diethanolamine in industrial scale via combined simulation and data-based optimization strategies

Removal of hydrogen sulfide in the gas phase by carbide slag modified bentonite

“…2,3 Currently, the industrial removal of H 2 S is primarily performed by wet removal methods, but the green removal of H 2 S is difficult. [4][5][6] Dry desulfurization methods are simple, stable, and produce little secondary pollution. [7][8][9] Adsorption is the most commonly used dry desulfurization method, but during the H 2 S adsorption, the loss of adsorbent is large, which decreases the desulfurization effect and increases the cost of its removal and purication.…”
