Plants have been supplied in the range 10,000 to 55,000 MTPY to operate with one process line to provide a high yield of hydrofluoric acid with efficient raw materials consumption. A high plant availability of 320-330 operating days per year is achieved and annual maintenance amounts to 4% of initial capital investment.
Product hydrofluoric acid is tailored to meet your requirements. Anhydrite, the calcium sulphate by-product, is sold to the building industry and cement industry.
The Prereactor is a special feature of our process technology. It is used for the initial reaction between fluorspar and sulphuric acid and it is such an efficient mixer with a high conversion rate that it is possible to use essentially the stoichiometric ratio of sulphuric acid to fluorspar. This allows a lower temperature range in the rotary kiln and therefore the rate of corrosion is considerably reduced. This achieves long operating campaigns for the plant and results in major savings in operating costs.
