Scope
GB/T 35254-2017 is the English-translated version of 烟气集成净化专用碳基产品.
GB/T 35254-2017 covers carbon-based products made specially for integrated flue gas purification. Clause 1 states that the standard specifies the terms and definitions, the classification, the main indicators and technical requirements, the test methods, the inspection rules and the marking, packaging, transportation and storage.
The same clause applies it to the carbon-based products used for the integrated removal of sulfur dioxide, nitrogen oxides, mercury and other pollutants from coal-fired power plant flue gas, non-ferrous metal smelting tail gas, sintering tail gas, coking flue gas and waste incineration flue gas, and adds that dedicated carbon-based purification products used to remove those pollutants from other flue gas may also refer to the standard.
The document is built as eight clauses, namely scope, normative references, terms and definitions, categories, main indicators and technical requirements, test methods, inspection rules and marking, packaging, transportation and storage, with four normative annexes on the 4 h sulfur capacity and cyclic sulfur capacity test, the test of the rate of denitrification, the testing of mercury content and the bulk density test.
Clause 3 defines integrated purification as a flue gas purification method for the synergistic removal of sulfur dioxide, nitrogen oxides, mercury and other pollutants, defines the special carbon-based product as a carbon-based material with a certain adsorption and catalytic capacity dedicated to integrated flue gas purification, and defines the 4 h sulfur capacity as the mass fraction of sulfur dioxide adsorbed per unit weight of carbon-based product within 4 h under the specified test conditions.
Clause 2 cites GB/T 6678-2003, GB/T 6682, GB/T 7702.1, GB/T 7702.7, GB/T 7702.9, GB/T 7702.10-2008, GB/T 7702.15, GB/T 16429, GB/T 20451, GB/T 30202.2 and GB/T 30202.3.
The draft on the page stops at the end of clause 3, so the technical requirements and the test methods are not shown. The page gives the standard as a recommended national standard under ICS 13.020.40 and Chinese classification J88, with an estimated 26,276 words, and derives it from National Standards Bulletin 2017 No. 32. It was issued on 29 December 2017 and has applied since 1 July 2018.
