この概要は現在英語のみで提供しています。

適用範囲

This standard applies to stable light hydrocarbons (also known as natural gasoline) extracted from natural gas condensate or crude oil in oil and gas fields. It covers liquid petroleum products primarily composed of pentanes and heavier hydrocarbons, with a final boiling point not exceeding 190°C. It is not applicable to other light hydrocarbon mixtures outside this specific extraction and processing scope.

技術要求

The standard categorizes stable light hydrocarbons into two grades (No. 1 and No. 2) based on their saturated vapor pressure ranges. No. 1 is designated strictly as a petrochemical feedstock, while No. 2 can be used as both a petrochemical feedstock and a blending component for motor gasoline. It mandates specific limits for distillation characteristics, including 10% evaporation temperature, 90% evaporation temperature, and final boiling point to ensure the product's volatility profile meets operational safety and processing needs. Seasonal adjustments for vapor pressure limits are defined for No. 2 products to accommodate summer and winter conditions. The standard sets strict sulfur content thresholds to minimize environmental impact and equipment corrosion. It also requires the product to be free of mechanical impurities and water, and mandates limits for copper strip corrosion to ensure material compatibility. Additionally, a minimum Saybolt color requirement is specified exclusively for No. 1 grade products. Compliance with these technical parameters is mandatory for all manufacturers and suppliers.

試験方法

The standard outlines specific testing procedures to verify compliance, including the Reid method for determining saturated vapor pressure and atmospheric distillation characteristics testing. Sulfur content is primarily measured using ultraviolet fluorescence methods, though alternative energy-dispersive X-ray fluorescence or coulometric methods are permitted for standard checks, with the former reserved for arbitration. Visual inspection is required for mechanical impurities and water, while the Saybolt colorimeter method and copper strip corrosion tests are utilized for quality assurance.

よくある質問

What products are regulated under GB 9053-2013?

It applies to natural gasoline extracted from gas condensate or crude oil, primarily composed of pentanes and heavier hydrocarbons, with a final boiling point not exceeding 190°C.

Are there any updates from the previous version of GB 9053?

The 2013 version updated seasonal definitions for vapor pressure, added alternative testing methods for sulfur content, and incorporated new safety requirements under GB 12268, while removing previous inspection rules and appendix content.

How does GB 9053-2013 differ from ISO standards?

It references several methods aligned with international standards, such as ASTM D86 for distillation and ASTM D5453 for sulfur content, but maintains specific domestic compliance protocols for Chinese market entry.
