BHS-Sonthofen Process Technology has supplied three larger than average indexing belt filters for the production of hydrofluoric acid. The key requirement for the design of the belt filters was particularly high chemical resistance given the strong acidic product attributes of the source material. BHS employed acid-resistant metallic materials and special plastics which offer maximum safety combined with high product quality. The plant has been in operation since the end of 2021.. BUSS-ChemTech in Pratteln, Switzerland, is internationally known as a supplier of customized and innovative process technologies for the chemical and aluminum industries. The company supports customers worldwide with its holistic solutions for chemical reaction processes, for example in the production of halogen-containing basic chemicals such as hydrofluoric acid, aluminum fluoride, phosgene, and their by-products. Recently, BUSS delivered the full process solution and the appropriate key-equipment for a project involving the production of hydrofluoric acid. In this case, a new, more environmentally friendly technology was used that converts fluorosilicic acid into silicon dioxide and valuable hydrofluoric acid. The latter can be further processed for profit, thus eliminating the need for costly neutralization and disposal. Indexing belt filter enables maximum yield To get this innovative project moving, BUSS relies on filtration technology from BHS. For the conversion process, the BHS experts provided the indexing belt filter of type BF 300, a continuously operating, horizontal vacuum filter.
