On January 10, the Ministry of industry and information technology released the draft of the implementation plan for cleaner production technology in titanium dioxide, coating, yellow phosphorus, chromium salt and barium carbonate for public consultation. According to these plans, the energy consumption, harmful waste gas and carbon dioxide emission of the five industries will be greatly reduced by 2014 through the implementation of cleaner production technologies such as the chlorination titanium dioxide boiling chlorination production technology and the selection of suitable experimental machine production process technology for the production of solvent based coatings

according to the plan, the annual production capacity of titanium dioxide industry adopting chlorination titanium dioxide production technology will reach 300000 tons by 2014, and the popularity of boiling chlorination production technology in chlorination titanium dioxide production will reach 60%; The continuous acidolysis production technology of titanium dioxide by sulfuric acid process, waste acid concentration technology of tail gas waste heat, heat utilization technology of sulfur titanium co production, acid hydrolysis black residue recovery technology, titanium dioxide top record of 16, and the comprehensive utilization technology of ferrous sulfate by-product reached 50% in the production of titanium dioxide by sulfuric acid process; The comprehensive utilization technology of gypsum, a byproduct of titanium dioxide, was applied and popularized. Due to the application of these technologies, it is estimated that by 2014, the whole industry can save 460000 tons of standard coal, reduce 384000 tons of waste residue and 480million cubic meters of harmful waste gas

the coating industry will focus on the development of environment-friendly coating technology represented by waterborne wood coatings, as well as the fully enclosed integrated production process technology of solvent based coatings and the clean production technology of amino resin. It is estimated that by 2014, the proportion of Waterborne Wood Coatings in wood coatings will reach 15%, and the fully enclosed integrated production workers will be 2.2 v= ω D × (3) formula (3) the popularization rate of the technology in the production of solvent based coatings reaches 10%. By applying these technologies, 139000 tons of oil resources and 27000 tons of chemical oxygen demand can be saved annually

by promoting the technology of deep purification and utilization of yellow phosphorus tail gas in the yellow phosphorus industry, by 2014, the utilization rate of yellow phosphorus tail gas will not be less than 90%, the utilization rate of electric furnace slag will not be less than 95%, the comprehensive energy consumption per ton of product will reach below 2.6 tons of standard coal, and the whole industry will realize the annual energy saving of 1.14 million tons of standard coal and the emission reduction of 3.2 million tons of carbon dioxide

the chromium salt industry should adopt cleaner production processes such as alkaline solution oxidation of ferrochromium to produce chromate, pneumatic fluidized tower type continuous liquid-phase oxidation to produce sodium chromate, potassium system sub molten salt liquid-phase oxidation and calcium free roasting, saving 325000 tons of standard coal, reducing 710000 tons of chromium slag and 3.65 billion cubic meters of waste gas

the barium carbonate industry will strengthen the construction of demonstration projects such as the utilization technology of rotary furnace tail gas waste heat boiler and the application of rotary furnace electrostatic precipitator technology. By adopting cleaner production technology, it is estimated that by 2014, the annual output of the whole industry will be about 700000 tons, 77400 tons of standard coal will be saved, and 1.12 million tons of wastewater will be reduced
