calcium carbide industry access conditions (revised in 2014)

,

,

In order to further curb blind investment, resolve the contradiction of overcapacity guide the healthy development of calcium carbide industry,

formulates these access conditions in accordance with relevant national laws, regulations industrial policies in accordance with the overall requirements of structural adjustment, effective competition, energy conservation consumption reduction, environmental protection safe production. I. layout of production enterprises According to the principle of "balanced population, resources environment, unified economic, social ecological benefits", the provincial industrial authorities should comprehensively consider resource reserves, energy supply, environmental capacity market dem, focus on the merger reorganization layout optimization of calcium carbide production enterprises in accordance with the concept of upstream downstream supporting development, no more isolated calcium carbide production plants will be added. (1) within scenic spots, nature reserves, drinking water source protection areas, key control areas for the prevention control of air pollution other areas that need special protection, within 2 kilometers outside the boundaries of urban planning areas coal resources areas, as well as on both banks of major rivers, highways, railways waterways, as stipulated by the State Council, the relevant departments of the state the people's governments of provinces (autonomous regions municipalities directly under the central government) It is not allowed to have mixed places such as food, medical facilities, medical facilities, medical facilities, medical facilities, etc. within 1 kilometer of the residential area, medical facilities, medical facilities, medical facilities, etc. (2) the newly-built or exped calcium carbide production plants must enter the industrial park with corresponding downstream industries supporting them; the existing calcium carbide production enterprises shall enter the industrial park before the end of 2020, form a close relationship with the downstream industries, so as to make the pollutants, by-products residues produced by calcium carbide production be comprehensively treated utilized. 2. Scale, technology equipment shall control the total capacity of calcium carbide. In principle, it is forbidden to build new calcium carbide projects. The new calcium carbide production capacity must be replaced by equal or reduced amount, the replaced capacity must be removed before the completion of new production capacity. Strengthen technological progress speed up the elimination of backward production capacity. (1) the advanced closed calcium carbide furnace must be adopted in the newly-built or exped calcium carbide production plant.

Encourage the development adoption of mechanized automatic discharging devices. Water cooled or air-cooled closed cooling tower is encouraged for cooling circulating water system. 3. Safety alarm facilities must be provided, video monitoring system must be set up in main production links to ensure continuous normal operation. (3) the existing calcium carbide enterprises must meet all the requirements of (2) above by the end of 2015. We should encourage existing enterprises to reduce excess capacity through merger reorganization, improve scale operation, develop reasonably. 3. Energy consumption comprehensive utilization of resources (1) newly built or exped calcium carbide production units, the electric energy consumption per ton of calcium carbide (converted into stard gas output of 300 L / kg) is less than 3200 kwh, the comprehensive energy consumption is less than or equal to 1.0 tons of stard coal. The existing calcium carbide production units should meet the above stards by the end of 2015. After the implementation of the new national stard of energy consumption quota per unit calcium carbide product, it shall be implemented in accordance with the new national stard. (2) the furnace gas of calcium carbide furnace must be 100% recycled comprehensively utilized, it is encouraged to be used for the production of chemical products with high added value. (3) the powder within the production boundary must be comprehensively utilized. (4) encourage the recovery utilization of sensible heat waste heat in calcium carbide production. Under the condition of mature technology, the sensible heat waste heat must be recycled in the newly-built exped calcium carbide production units. 4. Environmental protection (1) environmental assessment must be carried out in accordance with the law for the construction or reconstruction of calcium carbide production plants. All calcium carbide production must meet the national environmental protection requirements. The emission of air pollutants from calcium carbide furnace must conform to the emission stard of "ferroalloy smelting furnace" in "emission stard of air pollutants for industrial furnaces" (GB9078-1996).
