Desulfo-gypsum originates from electric power plants that use flue-gas desulfurizer. This paper analyses the character of desulfo-gypsum and discusses the feasibility and process of manufacturing desulfo-gypsum particleboard. The results showed that desulfo-gypsum could be used for producing gypsum particleboard (GPB) and the properties of GPB were better than that using natural gypsum.
Feb 06, 2019· Gypsum that comes from coal plants is called flue-gas desulfurization gypsum, as it comes from the process that scrubs sulfur out of the smoke stacks to reduce air pollution. The gypsum that is recovered has good quality, says Dick. The gypsum particles are small and uniform in size making them quite reactive.
