 (1) Expanded hydrofluoric acid production equipment, after 72 hours of continuous production examination, each fluorinated product of hydrogen fluoride fluorite (powder) (standard YB /T 5217, calcium fluoride content of not less than 97%) consumption higher than 2.25 tons, comprehensive water consumption shall not exceed 1 ton, the average annual comprehensive energy consumption shall not exceed 450 kilograms of standard coal.

(2) Hydrofluoric acid production enterprises should develop a recycling economy, improve energy utilization and fluorite, fluoride gypsum slag and other comprehensive utilization of resources level.

Fluoride gypsum slag calcium sulfate content shall not be less than 90%, calcium fluoride content shall not exceed 2%, sulfuric acid content shall not exceed 0.5%, the comprehensive utilization rate must be 90% (including the signing of long-term contract commissioned processing use).

 (3) New or expansion device of hydrofluoric acid, the water recycling rate should not less than 95%.

Existing hydrofluoric acid production enterprises should be through transformation, through transformation can not reach, to stop production or exit on schedule.
