氫氣相關化學製程被相當廣泛地應用在化學工業之生產流程,典型的製程有不飽和碳氫化合物的氫化反應(例如烯類)、氨氣的合成及金屬氧化物之還原反應以提煉金屬。由於氫氣與氧或空氣混合氣體具有很寬廣的爆炸範圍(4~75%),且氫氣最低引火能量(MIE)只有0.03 mJ,極易導致強烈爆炸情況。另外氫氣易於擴散,其擴散速率為空氣的4倍,可在極細的間隙逸散,尤其在高溫,會透過鋼材或其他金屬材料,引起氫氣侵蝕的問題。而一般氫氣相關化學製程如烯類氫化反應,必須在較嚴苛的操作條件下進行,且是呈現放熱反應。故一旦發生製程偏離,將可能引發不預期的反應或失控反應,而導致意外事故。
本研究是藉由搜集歷年來氫氣相關化學製程之意外事故,對事故發生過程做深入分析,以了解其潛在之危害源。再利用根源分析(Root Causes Analysis)方法,由這些不期望發生的意外事故,如火災、爆炸等有系統的去追溯造成該事故之各種原因,並探討應該採取那些合適的措施及設置那些安全防範設施,以降低或消除危害源。最後再將上述這些因果關係,發展一套簡易的氫氣相關化學製程危害分析資料庫。使得不需專家的協助,即能直接應用於製程開發及工廠操作階段,可供製程安全設計、危害分析及安全操作之參考。
Hydrogen related chemical processes have been widely used in the production processes of the chemical industry. The typical processes include the hydrogenation of the unsaturated hydrocarbon compounds (for example alkenes), the synthesis of ammonia, and the reduction of metal oxide for metal refining. Hydrogen gas has very wide explosion limit (4~75%) and very low minimum ignition energy (0.03mJ) and is thus highly vulnerable to fire and explosion. Moreover, diffusion rate of hydrogen is 4 times higher than that of the air rendering the hydrogen to permeate easily even in small gaps. Hydrogen may also pass through the steel or other material, especially in high temperature, causing hydrogen attack. On the other hand, most hydrogen related chemical processes, for example alkenes hydrogenation, have to operate under rigorous condition and are also exothermic. Any process deviation may lead to unexpected reactions or runaway reactions and resulted in incident.
This study analyzes the safety of the hydrogen related chemical process by collecting a variety of relevant incidents. By using Root Causes Analysis (RCA) method, the causes and potential hazards of the incident are identified. Methods to reduce or eliminate the potential hazards are also provided. All these information are summarized and build into a database for analyzing the hazards in hydrogen related processes. The database can be used with ease even for novice engineers in assessing hazards in hydrogen related processes during process design or operation.
