(Specification)Standard Specification for Xylenes for p-Xylene Feedstock
Standard Specification for Xylenes for <i>p</i>-Xylene Feedstock
ABSTRACT
This specification covers xylenes for p-xylene feedstock. Xylenes for p-xylene feedstock shall conform to the following requirements: p-xylene minimum weight percent, ethylbenzene maximum weight percent, toluene maximum weight percent, C9 and higher boiling aromatic hydrocarbons maximum weight percent, nonaromatic hydrocarbons maximum weight percent, nitrogen maximum weight percent if needed, sulfur maximum content, appearance, chloride if needed, color, and distillation range.
SCOPE
1.1 This specification covers xylenes for p-xylene feedstock. These xylenes typically are extracted from reformate.
1.2 The following applies to all specified limits in this specification: for purposes of determining conformance with this specification, an observed value or calculated value shall be rounded off “to the nearest unit” in the last right hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.4 Consult current OSHA regulations, suppliers' Material Safety Data Sheets (MSDS), and local regulations for all materials used in this specification.
