　　模块：核心规定

　　Module: Core Regulations

　　油气收集系统：

　　Oil and gas collection system:

　　- 储罐区：区分“直接连通”和“单罐单控”两种收集方式，装船设施需设置船岸安全装置（含快速切断阀、含氧量检测等）

　　-Tank area: distinguish between "direct connection" and "single tank single control" collection methods, and ship loading facilities need to be equipped with shore safety devices (including quick shut-off valves, oxygen content detection, etc.)

　　- 装载系统：装车/装船油气收集管道应设切断阀，装船栈桥根部陆域侧需设远程控制切断阀（距码头前沿≥20m）

　　-Loading system: The oil and gas collection pipeline for loading/shipment should be equipped with a shut-off valve, and a remote control shut-off valve should be installed on the land side at the root of the loading dock (at least 20m away from the dock front)

　　回收/处理装置：

　　Recycling/processing equipment:

　　- 油气浓度＞30g/m时宜采用回收装置（吸附、吸收、冷凝等物理方法）；≤30g/m时宜采用处理装置（燃烧、氧化等化学方法）

　　-When the oil and gas concentration is greater than 30g/m, it is advisable to use a recovery device (physical methods such as adsorption, absorption, condensation, etc.); When ≤ 30g/m, it is advisable to use treatment devices (chemical methods such as combustion, oxidation, etc.)

　　- 装置设计规模应考虑110%超负荷运行能力，适应油气浓度波动

　　-The design scale of the device should consider a 110% overload operating capacity to adapt to fluctuations in oil and gas concentration

　　安全与环保：

　　Safety and Environmental Protection:

　　- 管道设计压力≥1.0MPa，真空管道≥0.1MPa外压，阀门、管件材质需与管道匹配

　　-Pipeline design pressure ≥ 1.0MPa, vacuum pipeline ≥ 0.1MPa external pressure, valve and pipe fitting materials need to match the pipeline

　　- 尾气排放需满足国家有机气体控制指标，换热器压降≤300Pa，凝缩液禁止排入污水系统

　　-The exhaust emissions must meet the national organic gas control standards, with a pressure drop of ≤ 300Pa in the heat exchanger, and condensed liquid must not be discharged into the sewage system

　　3.修订亮点

　　3. Revision highlights

　　适用范围扩展新增煤化工企业及储罐区、装船系统的油气回收要求，解决原标准覆盖不全问题。安全措施强化明确储罐区和装船设施的防爆、防雷、防静电设计，新增吸附罐失电保护、反应器超温联锁等条款。环保指标升级尾气排放限值与现行环保标准联动，推动低碳技术应用。

　　Expand the scope of application to include oil and gas recovery requirements for new coal chemical enterprises, storage tank areas, and shipping systems, and solve the problem of incomplete coverage of the original standards. Strengthen and clarify the explosion-proof, lightning protection, and anti-static design of storage tank areas and loading facilities, and add clauses such as adsorption tank power loss protection and reactor overheating interlock. Upgrading environmental indicators and linking exhaust emission limits with current environmental standards to promote the application of low-carbon technologies.
