Foreword
This standard is a revision of GB9053-88 "Stabilized Light Hydrocarbons". The main contents of this revision include:
1. Added a preface to the drink;
2. Added the definition of stable light hydrocarbons:
3. The latest standards that are more suitable for stable light hydrocarbons are adopted in the cited standards in Chapter 2. The sampling method used SY/T0543-94 instead of GB4756--84. The distillation method used GB/T6536-1997 instead of GB6536-88; GB 150--1998 was added;
After standard cleaning and rectification, the reference number of the standard There have also been changes, so corresponding adjustments have been made; 4. Added Chapter 6.4 Judgment Rules for the Quality of Stable Light Hydrocarbon Products in Chapter 6 Inspection Rules. This standard will be implemented from September 1, 1998. From the effective date of this standard, Appendix A, which replaces GB9053-88, is the standard appendix.
This standard is proposed by China National Petroleum Corporation. This standard is under the technical jurisdiction of China National Petroleum Corporation Planning and Design Institute. This standard was drafted by China National Petroleum Corporation Daqing Oilfield Construction Design Institute. The main drafters of this standard: Ba Xili, Sun Daijun, Zhou Xiqing, and Xiong Liangfu. This standard was first published in April 1988.

Saturation vapor pressure, extended range, mechanical impurities and moisture items must be inspected for each batch of delivery. Stainless steel corrosion items shall be randomly inspected once a month. 6.2 Sampling shall be carried out in accordance with SY/T543-94. The delivery unit shall determine the quality according to the sampling test results of the storage tank or specified transfer point of the shipped product. If it is qualified, the product shall be issued and a product quality certificate shall be issued. Certificate of conformity and product mark card. 6.3 The receiving unit has the right to randomly inspect the quality of the issued products. If it is found that the quality of the product does not meet the requirements of this standard, it may request re-inspection of the retained samples and use the analysis results of the retained samples as the basis for arbitration. The samples are kept for three months. 6.4 The main indicators of the product include saturated vapor pressure, distillation range, sulfur content, mechanical impurities and moisture. If any one of them is unqualified, the product is unqualified. If both copper sheet corrosion and color indicators are unqualified, the product is unqualified.

A3.2 When this product is transported by tanker, No. 1 The product must be transported using a pressure tank truck that is suitable for the saturated vapor pressure of the product. If such a tank truck is not available yet, a liquefied petroleum gas tank truck can be used instead. For No. 2 products, current gasoline tank trucks or gasoline iron drums can be used for transportation. .A3.3. The unit that provides containers shall ensure that it provides clean pressure vessels that meet the requirements of these regulations. The shipping unit should accept its "factory certificate" or *inspection certificate, and it must be filled within the validity period of use. If there is a dispute over the determination of the degree of qualification, it will not be filled. A3.4 For No. 1 products, it must be Use closed loading and unloading methods. For No. 2 products, close loading and unloading should be used as much as possible. When conditions are not met, the oil loading pipe should be extended to the bottom of the tank to fill the oil, and the gas at the top of the tank should be led to a safe place for discharge. All crane tubes must be electrostatically grounded. A3.5 The maximum filling volume of this product must not exceed 85% of the tank volume. A3.6 After filling the oil tanker, tanker, and oil drum, add a sealing gasket to the normal pressure container. Tighten the cap and close the valve of the pressure vessel to prevent leakage. The transportation department must carefully check the seals and protect them during storage and transportation to avoid accidents during loading and unloading. When opening and closing the cover and connecting the union, special non-fire tools must be used, and iron tools such as chisels and hammers must not be used to strike to avoid accidents
A3.8 See A1.3 for safety regulations during tank truck transportation. A3.9 When transported by tanker, the tanker must be equipped with anti-static, dry powder fire extinguisher and automobile smoke exhaust fire extinguisher. 21
