In order to optimize the allocation of fluorine resources and establish a resource-saving, environment-friendly, and intrinsically safe fluorine chemical industry system, the Ministry of Industry and Information Technology released the “conditions for the access of hydrogen fluoride industry†(hereinafter referred to as “accessâ€). The "conditions") impose stringent conditions on the new hydrogen fluoride production capacity in terms of industrial layout, scale, technology, equipment, and environmental protection indicators.
In an interview with reporters, Mei Shengfang, an expert in China's fluorosilicone organic materials industry association who participated in the drafting of the “Entry Conditions,†stated that the introduction of this policy is based on the protection of national strategic resources. After China introduced the restrictive measures for fluorite resources, many companies converted fluorite resources into hydrogen fluoride products, resulting in the emergence of new production capacity. At present, the operating rate of the hydrogen fluoride industry in China is only 50%, and the production capacity is in excess. Taking full account of the internal and external needs of the "12th Five-Year" hydrogen fluoride industry, the introduction of "Entry Conditions" can well control the new production capacity and ease the current situation of excess capacity.
In terms of industrial layout, the “Entry Requirements†requires that new production facilities or enterprises must enter development zones that have environmental and safety capacity, have facilities for the comprehensive utilization of fluoride-containing pollutants and resources, and storage facilities for hazardous chemicals. Existing hydrogen fluoride production enterprises that are not in the development zone shall not add new hydrogen fluoride production capacity, and encourage these enterprises to suspend production or relocate to the development zone. In addition to the development and production of high-purity, ultra-clean electrons and other industries dedicated to hydrogen fluoride products and the production of hydrogen fluoride for their own use of raw materials, new construction, expansion of non-raw materials for hydrogen fluoride production facilities.
In terms of scale, technology and equipment, the “Entry Requirements†requires that the total annual production capacity of an enterprise should not be less than 50,000 tons, and the annual production capacity of a newly-built unit should not be less than 20,000 tons. Newly-built, rebuilt or expanded hydrogen fluoride production facilities should adopt advanced technology and energy-saving, environmental protection, and safety equipment. At the same time, a fluorine-containing dust collection and utilization system, a fluorine-containing wastewater treatment system, and a fluorine-containing slag resource recycling system should be supported. It is forbidden to use fluorite as a raw material and adopt a direct water absorption process to newly construct and expand hydrofluoric acid production facilities.
The “Entry Requirements†stipulates strictly the various environmental protection indexes of hydrogen fluoride production enterprises: The consumption of fluorspar (powder) per ton of hydrogen fluoride product shall not exceed 2.25 tons, the comprehensive water consumption shall not exceed 1 ton, and the annual average comprehensive energy consumption Not more than 450 kg of standard coal, the water cycle utilization rate shall not be less than 95%; Fluorine-containing gypsum slag ** Calcium content shall not be less than 90%, *** content shall not exceed 2%, ** content shall not exceed 0.5%, Annual comprehensive utilization The rate must be above 90%. Newly built, rebuilt or expanded hydrogen fluoride production facilities must meet the above environmental protection requirements. Existing hydrogen fluoride production enterprises must meet the above requirements by the end of 2013, otherwise they will stop production or withdraw from production on schedule.
