• 中文摘要： 本文是探討如何利用加速熱卡計 ARC(accelerating rate calorimeter)反應系統所得之數據,來設計反應器或儲槽的壓力洩放系統,用來克服由於反應器內過高之壓力所造成的爆炸行為而導致的工業災害問題。本文所採用之程序是利用苯乙烯合成聚苯乙烯之聚合反應,由於該程序在反應過程中會放出大量的熱量,因此會造成反應器內溫度及壓力的急劇上升,所以我們便採用此一典型的高溫、高壓程序來說明反應器壓力洩放系統的設計過程; 當然,此設計理論亦可應用到其他的反應系統上。由模擬結果得知,起始劑濃度及單體濃度的改變會影響到反應器內最大壓力及最大溫度的值,也就是說當起始劑及單體濃度增加時,反應器需要較大的洩放管徑來排放高壓氣體。但是當過壓(overpressure)愈大時,其洩放管徑就愈小,原因是當反應器內之壓力還不是很高時,洩放管之閥便開啟以供排放高壓氣體,故不需要較大的洩放管徑。
• 英文摘要： This paper discusses how to use the simulation data obtained from the accelerating rate calorimeter (ARC) model to design the emergency relief systems for chemical reactors and storage vessels to overcome the problem of reactor explosions resulted from excessive pressure and thus the disastrous incidents can be avoided. Here the styrene polymerization reaction is chosen as the reaction system to describe the designing of the emergency relief system by the ARC data. The simulation results show that the change of the initial and the monomer concentration will influence the maximum temperature, pressure, and the rate of temperature rise in the reactor. In other words, when the initial and the monomer concentration increase, a larger vent diameter will be needed to release the fluid. The simulation results also illustrate that in the designing of the emergency relief system, the larger the overpressure is, the smaller the vent diameter will be needed.
