本文讨论的两种风化方法是对水中溢油受17影响的相对简单的风化过程的近似。其他更复杂的风化方法也可用于提供风化的原油样品, 例如由 Brandvik 和 Faksness35描述的循环水槽。所提出的方法的优点是, 它们需要简单的设备, 并且可以很容易地在实验室环境中进行。由此产生的风化原油随后在本议定书的易燃性和燃烧效率研究中发挥作用, 如 "代表性成果" 一节所?...

就地在水中燃烧溢油是一种海洋溢油反应方法, 它通过燃烧并将其转化为烟尘和气体燃烧产品, 将溢油从水面上除去。此响应方法在埃克森美孚1和深水地平线2漏油期间成功应用, 并经常被提及为北极3、4、5 的潜在溢油响应方法. ,6。确定就地烧油是否成功的两个关键参数是溢油反应方法, 即燃油的易燃性和燃烧效率。第一个参数, 易燃性, 描述了如何容易点燃燃料, 并可能导致火焰蔓延到燃料表面, 导致完全发展的火灾。第二个参数, 燃烧效率, 表示石油 (在 wt%) 的数量, 有效地从水面上被大火清除。因此, 在原位燃烧条件下, 了解不同原油的易燃性和预期燃烧效率是相关的。
为就地燃烧目的而在水上点火是一个实际问题, 在点火系统上进行定性讨论5,7,8,9。将溢油点火作为二进制问题的实用方法, 并将油标为 "可燃性" 或 "不可燃性" (例如Brandvik、Fritt-拉斯穆森、 et al.10) 然而, 从根本观点看是不正确的。理论上, 任何燃料都可以被点燃, 给出适当的点火源。因此, 对各种不同原油类型的点火要求进行量化, 以更好地了解将其标记为 "不可燃性" 的原油的性质是相关的。为此, 本发明的方法可用于研究油的点火延迟时间, 即入射热流、油的临界热流及热惯量, 如: 加热油的难度. 
在前面的研究中, 我们假设控制燃烧效率的主要参数是对燃料表面的热反馈11, 它是池直径的函数。该理论解释了燃烧效率的表观池大小依赖性基于实验室研究报告低燃烧效率 (32-80%)8,12,13和大规模研究 (水池直径≥2 m)报告高刻录效率 (90-99%)14,15,16。本文所讨论的方法旨在对所提出的理论进行测试。通过将小规模实验室实验引入到恒定的外热流中, 可以在受控实验室条件下模拟大型池火灾的高热反馈。因此, 所开发的方法可以通过改变外部热流, 有效地研究燃烧效率作为直径的函数。
除了外部热流来模拟较大规模的就地燃烧操作, 实验设置的特点是冷却浮油的冷水流量, 模拟的冷却效果的海流。讨论的方法还与新鲜的和风化的原油兼容。原油的风化描述了在水溢出后影响原油的物理和化学过程, 例如挥发性成分的损失和与水混合形成油水乳剂 (例如, AMAP17)。蒸发和乳化是影响原油可燃性的两个主要的风化过程18和模拟这些风化过程的协议包括在讨论的方法中。
在此, 我们提出了一种新的实验室方法, 确定原油的可燃性和燃烧效率的条件下, 模拟就地燃烧作业在海上。以往对原油可燃性和燃烧效率的研究具有可比性和不同的方法。在水的19和北极温度20下, 研究了新鲜和风化原油作为外热流作用的可燃性。燃烧效率研究通常侧重于不同类型的新鲜和风化的原油和环境条件的固定规模 (例如, Fritt-拉斯穆森, et al.8Bech、Sveum、 et。21). 最近一项关于化学牧民所含原油燃烧的研究, 以作者的知识为基础, 首先研究了类似条件下的小型、中型和大型实验的燃烧效率13。然而, 由于进行此类实验所需的大量时间和资源, 大规模的实验并不容易用于参数研究。所提出的方法的主要优点是, 它允许同时研究在半现实条件下原油的可燃性和燃烧效率。通过容易重复的实验, 将这两种原油参数作为不同油型和 (模拟) 池直径的函数结合起来, 在实践中是行不通的。

experimental procedure for laboratory studies of in situ burning : flammability and burning efficiency of crude oil

提出了通过两个实验实验室设置同时研究新鲜风化原油可燃性和燃烧效率的新方法。实验是容易重复的与操作的规模实验 (水池直径≥2 m), 同时仍然具有相当现实的就地燃烧条件原油在水。实验条件包括一个流动的水分层, 冷却浮油和外部热流 (高达50千瓦/米2), 模拟高热量反馈到燃料表面的操作规模原油池火灾。这些条件使对原油池火灾的燃烧效率进行控制的实验室研究相当于操作规模试验。该方法还根据临界热流、点火延迟时间、入射热流的作用、点火时的表面温度和热惯量等方面提供了对原油点火要求的定量数据。此类数据可用于确定点火源的所需强度和持续时间, 以点燃某种新鲜或风化的原油。该方法的主要局限性是, 流动水分层对燃烧原油作为外热流作用的冷却效果尚未完全量化。实验结果清楚地表明, 流动的水分层确实改善了该安装程序在原位燃烧条件下的代表性, 但在何种程度上, 这种表示是准确的目前还不确定。然而, 该方法具有最逼真的就地燃烧实验室条件, 目前可同时研究原油在水中的可燃性和燃烧效率。

图 5显示了使用步骤2中描述的方法在多天内蒸发掉的轻质原油的蒸发曲线, 损失为 30 wt%。这一数字清楚地表明, 在蒸发风化的第一天 (19 小时) 之后, 蒸发率大大降低, 这就使得协议中提到的停顿。
图 6显示了点火延迟时间, 它是由锥形加热器 (步骤7、图 2-3...
