T/GPCIA 0004-2022 Ethylene cracking of mixed carbon eight
Basic Information
Scope
Scope: This document specifies the technical requirements, test methods, inspection rules, and marking, packaging, transportation, storage, and safety of ethylene cracking mixed C8. This document is applicable to mixed C8 produced by ethylene plants, which can be used as raw materials for styrene extraction plants. Main technical content: Table 1 Technical requirements for ethylene cracking mixed C8 Item Indicator Appearance Transparent liquid, no free water Density (20℃), kg/m3 ≤940 Toluene, w% ≤2.5 Ethylbenzene, w% Measured value Xylene, w% Measured value Styrene, w% ≥12 Total C8, w% ≥30 C8 and above components, w% ≥80 a Total C8 refers to the sum of ethylbenzene, xylene, and styrene components. b C8 and above components refer to all components following ethylbenzene (including ethylbenzene) in the order of chromatographic peaks.
