Investigation on the condensation behavior of the trace element zinc in (Ar/H2O/HCl/H2S) gas mixtures and its practical implications in gasification-based processes for energy and power generation

•Zinc condensation behavior is investigated under gasification conditions.•Influence of the (HCl/H2S) gas mixtures on zinc condensation behavior is studied.•Scheil-Gulliver cooling model provides a good reference for condensation analysis.•The mechanisms for zinc condensation processes in gas mixtures are proposed.•Potential applications in IGCC power plants and future directions are discussed.
