This specification is revised according to the notice of the former China National Petroleum Corporation (98) Technical Supervision No. 33 and the Henan Petroleum Exploration Bureau Survey and Design Institute on the "Crude Oil Stabilization Design Technical Specification" SYI0069~-92. This revision solicited opinions from relevant units and absorbed the scientific research results and experience of crude oil stabilization device design and construction in recent years. In addition to the revision of the content and structure of SY/0069=-92, it also added chapters on safety and environmental protection, oil tank hydrocarbon vapor recovery, and device design for special environments.
This specification is interpreted by Henan Shirun Exploration and Design Institute. This specification was proposed by China National Petroleum Corporation. This specification was proposed by the Oilfield Engineering Construction Design Professional Standardization Committee. This specification will take effect from the date of entry into force, and will replace SY70069-92. This specification was first issued in November 1992, and this is the first revision. Editor: Henan Petroleum Exploration and Design Institute. Main drafters: Zheng Youlin, Pan Yuqi, Liu Zilin, Zhou Tuhua, Yuan Zhijun, Bai Junsheng, Wang Xiaohui.

3 Basic regulations
3.0.1 The purpose of crude oil stabilization is to reduce the evaporation loss of crude oil and to ensure the safety of crude oil during transportation. 3.0.2 The collection and treatment process before crude oil enters the stabilization device must be closed. 33 The stabilization of crude oil is measured by the saturated vapor pressure of the stabilizing crude oil. The saturated vapor pressure of the stabilizing crude oil should be determined based on the light component content in the crude oil, the storage and external transportation conditions of the stabilizing crude oil, and the design value of the saturated vapor pressure of the stabilizing crude oil at the storage temperature should not exceed 0.7 times the local atmospheric pressure. 3.0.4 The test method for crude oil saturated vapor pressure shall be carried out in accordance with the provisions of the current national standard "Reference method for measuring saturated vapor pressure of crude oil" GB/T11059. 3.0.5 The test method for crude oil evaporation loss shall be carried out in accordance with the provisions of the current petroleum and natural gas industry standard "Measurement of crude oil loss in oil fields" SY267: The evaporation loss of newly-generated crude oil shall be predicted by simulation calculation according to the collection and storage conditions. 30.6 The evaporation loss rate of crude oil in the oil field is less than 0.2% (mass fraction). It cannot be stabilized. However, when it can achieve better economic benefits in combination with other processes, it can also be treated.
3..7 The scale of crude oil storage should be appropriate to the oil production of the oil field (or block) under its jurisdiction, and the allowable fluctuation range is 80% to 20%. 308 The annual operation time of the original stable installation is pulled up on the natural gas installation operation street system- The gas from the crude oil stabilization device shall not be directly used as fuel. The collected condensate is strictly prohibited from being transported and stored. It must be stabilized or stored in a closed manner. The light hydrocarbons in the stabilization process shall meet the requirements of the current national standard "Light Hydrocarbons in Stabilization" GB9053, or be added to other chemical products. 3.0.10 The scale of the crude oil stabilization device shall not be less than 30:10a. It shall be planned in a coordinated manner with crude oil dehydration, natural gas treatment and processing, external heating, cogeneration, etc., to make rational use of energy and improve oil-gathering and transportation. The overall economic benefits of the treatment system
