(1) Raw materials: produce 1 ton of hydrofluoric acid consumption of fluorite (97%) of 2.2 to 2.35 tons, sulfuric acid and 2.6 to 2.8 tons. Actual consumption related to fluorite quality, technology, production and management. Our raw materials consumed in the production technology has been close to the international advanced level. (2) Cold consumption: at design temperature or -15 ℃ -10 ℃ operating temperature, produce 1 ton of hydrofluoric acid to consume 80 to 1,200,000 kcal of refrigeration. The amount consumed is much larger than the international advanced indicators, there should be a greater decline in space; the underlying data and the design or production process which is mainly used in the process indicators related to process control, process control and only the index is set at an appropriate value, only It can reduce the energy consumption of the section. (3) Fuel: hydrofluoric acid to produce 1 ton of coal consumed 300kg ~ 350kg, wherein the heating value of coal by 5500kcal / kg meter. Calorific value compared with theoretical calculations, energy utilization rate is only 20 to 30%.
