Comparison of Gypsum Dewatering Technologies at Flue Gas Desulfurization Plants

Recovering gypsum from flue gas desulfurization (FGD) plants is becoming more important as the technical feasibility of substituting FGD gypsum for natural gypsum in traditional applications such as wall board, cement and soil conditioners has been demonstrated. It is estimated that there are over 200 new coal-fired plants and over 1000 upgrades of existing coal-fired plants in various stages around the world. An important aspect of gypsum recovery is the solid-liquid separation technology that is used.

Evaluating thin-cake pressure filtration using the BHS Autopress technology

Chemical Processing Magazine

Thin-cake pressure filtration technology offers an alternative to agitated nutsche filters and centrifuges for solid-liquid separation,cake washing, and drying. Complicating this process is the number of competing technologies and options that can be employed to accomplish these steps. For example, most pharmaceutical processes will use either an agitated nutsche filter or a centrifuge for the separation and washing step. This article discusses the use of the thin-cake Autopress pressure filter as an alternative to agitated nutsche filters and centrifuges. The results are applicable to specialty chemical and other applications with similar process crystals and requirements.
