On March 9, the Ministry of Industry and Information Technology formally issued the “Entry Conditions for HF Industryâ€, which stipulated that in addition to the stable and reliable fluorite and other resource guarantees, the new hydrogen fluoride installations must enter economic development zones with certain conditions. Existing hydrogen fluoride production enterprises that are not in the development zone may not add new production capacity except for safety and environmental protection reforms. Access conditions stipulate that new hydrogen fluoride production facilities must enter into development zones with environmental capacity and safety capacity, possessing comprehensive utilization facilities for the treatment and recycling of fluorine-containing pollutants, as well as storage and transportation facilities for hazardous chemicals, and vigorously developing circular economy. In terms of scale, the total scale of hydrogen fluoride in newly-built production enterprises shall not be less than 50,000 tons/year, and the production capacity of a single set of equipment shall not be less than 20,000 tons/year. In terms of technology, it is forbidden to use fluorite as raw material and adopt water direct absorption technology to newly construct and expand hydrofluoric acid production equipment. In respect of energy consumption, the access conditions stipulate that the newly-built, rebuilt or expanded hydrogen fluoride production unit, after continuous 72-hour production assessment, the consumption of fluorspar (powder) per ton of hydrogen fluoride product shall not be higher than 2.25 tons, and the comprehensive water consumption shall not be higher than 1 ton. The average annual comprehensive energy consumption shall not exceed 450 kg of standard coal.
