SMM News: Great Wisdom AAStocks Newswires November 13 hearing, was placed high expectations "titanium dioxide industry access" was first disclosed. China Coating Industry Association, Branch Secretary Guo Xinrong titanium dioxide industry in 2013 annual meeting of the titanium dioxide industry sources, the manuscript of this revision, the major increase in the allocation of resources and resource recovery, process advanced features, process system energy parameters, cogeneration 4 new Terms Act (sulfuric acid) process routes.
He said that the current "titanium grade 2 sheet dioxide industry access" to other content changed little, before the official announcement next year, there will be further revised and improved. To be adopted "the titanium dioxide industry access conditions" of "Terms" adjustment, upgrade and healthy development of China's titanium dioxide industry.
But several participants to the great wisdom agency insiders analysis, "titanium dioxide industry access" new four provisions limiting effect on the titanium dioxide industry is small, while the access conditions can really implement surviving in challenge.
** Resource allocation and resource recovery terms **
Allocation of resources and recycling provisions: first, provides an important indicator of the production process of acid hydrolysis rate and the recovery of titanium dioxide, etc., requires companies to adopt advanced technology to promote industrial upgrading.
Among them, the sulfuric acid production process systems acid hydrolysis rate ≥98.5% acid solution and the whole process of titanium dioxide yield of ≥88%, the chloride process titanium dioxide production yield of the whole process of ≥92%.
Secondly, according to introduced, said that no matter what the medical titanium plate dioxide production process, its byproducts process must establish a "resource recycling system," which is the revised version of a very important part.
(1) For the chloride process capacity, made the following four requirements: First, encourage the use of high-grade titanium-rich material TiO2≥90%, improve the utilization of resources from the source; secondly, we must build a separate chlorination collecting slag and slag processing step being performed in a closed residue field stockpiling; then, the production of hydrochloric acid by-product recycling and building a database storage utilization; and finally, the waste generated by molten salt chlorination comprehensive utilization of the remaining portion of the slag in seepage field stockpiling.
(2) For the sulfuric acid production process, made the following three requirements: First, the acid hydrolysis residues must enter the resource recovery mode can be: flotation recovery process, "Asian dissolved salt technology" disposal and recycling magnetic separation process and other options; secondly, the recovery of ferrous sulfate heptahydrate way, must be "self, outsourcing, trade" and other ways to quantify treatment byproducts 100%, where conditions permit, to encourage the use of "slag, mine" mixed mode regulation of ferrous sulfate heptahydrate generation and use; and finally, recycling titanium gypsum, has become one of the sulfuric acid production can "sustainable development", highlighting the contradictions can not be avoided. Revised highlighted the "recycling" of the quantization scale. Namely: the proportion of harmless treatment compliance after open dumps or landfills generate total ≤70%; into the cement industry and building materials industry recycling rate ≥30%.
Guo Xinrong concluded that build and promote the process of titanium dioxide byproducts resource recycling system is a complex system engineering local government, titanium dioxide business and the whole society; traditional values and local interests will face a conflict; it must be adapted to local conditions, not to engage in "blanket", firmly and unswervingly.
Terms ** ** process advanced features
Terms of process advanced features: whether the country is "encouraged" process and the "new limit class" process, revision should have clearly defined the current domestic and international advanced technology, in order to avoid and prevent "flattened capacity expansion." drawbacks, promote industrial upgrading and technological progress.
(1) titanium tetrachloride crude chloride process titanium dioxide focus "gas-phase oxidation" process and titanium sponge "magnesium electrolysis" technology feature differences, encourage boiling chlorination process; titanium tetrachloride purification chloride process of encouraging the use of organics except vanadium resource conservation process.
(2) sulfuric acid process must be introduced and the use of "continuous acid hydrolysis process" (to give compliance period) and the "waste acid enrichment technology."
** ** Process system energy parameters Terms
Terms of energy technology system parameters: revision of energy consumption indicators, using the (National Energy Board) recently organized to discuss the preparation of indicators, as a unified evaluation scale.
** Cogeneration (sulfuric acid) process route Terms **
Cogeneration (sulfuric acid) process route provisions: provisions in different regions, different environments and different resource allocation conditions to encourage the appropriate area to build "sulfur × titanium" co-production of industrial clusters.
(1) business (Park) location perovskite abundant resources, encourage construction of "sulfur - Titanium" cogeneration system.
(2) business (park) there are other "sulphate" allocation of resources, advocate building "sulfur × titanium" system.
