　　模塊：核心規定

　　Module: Core Regulations

　　油氣收集系統：

　　Oil and gas collection system:

　　- 儲罐區：區分“直接連通”和“單罐單控”兩種收集方式，裝船設施需設置船岸安全裝置（含快速切斷閥、含氧量檢測等）

　　-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.)

　　- 裝載系統：裝車/裝船油氣收集管道應設切斷閥，裝船棧橋根部陸域側需設遠程控制切斷閥（距碼頭前沿≥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/處理裝置：

　　Recycling/processing equipment:

　　- 油氣濃度＞30g/m時宜采用回收裝置（吸附、吸收、冷凝等物理方法）；≤30g/m時宜采用處理裝置（燃燒、氧化等化學方法）

　　-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.)

　　- 裝置設計規模應考慮110%超負荷運行能力，適應油氣濃度波動

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

　　安全與環保：

　　Safety and Environmental Protection:

　　- 管道設計壓力≥1.0MPa，真空管道≥0.1MPa外壓，閥門、管件材質需與管道匹配

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

　　- 尾氣排放需滿足國家有機氣體控制指標，換熱器壓降≤300Pa，凝縮液禁止排入污水系統

　　-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.修訂亮點

　　3. Revision highlights

　　適用范圍擴展新增煤化工企業及儲罐區、裝船系統的油氣回收要求，解決原標準覆蓋不全問題。安全措施強化明確儲罐區和裝船設施的防爆、防雷、防靜電設計，新增吸附罐失電保護、反應器超溫聯鎖等條款。環保指標升級尾氣排放限值與現行環保標準聯動，推動低碳技術應用。

　　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.
