用于分析钻井液中所含的至少一种烃的设备及相关方法
摘要：
设备包括提取器(53)，所述提取器具有出口(71)，在所述出口处对气流取样。所述气流包含至少一种待分析的烃和至少一种干扰化合物。输送管线(54)连接至所述提取器(53)的所述出口(71)以便将所述气流输送至分析器(55A)，所述分析器包括能够测量这种气流中所含的所述至少一种待分析的烃的检测器。所述设备包括定位在所述提取器(53)与所述检测器之间的化学反应器(141)。所提取气体的至少一部分被输送通过所述化学反应器(141)，在所述化学反应器中进行至少一种干扰化合物的选择性催化反应，而所述至少一种待分析的烃没有任何实质反应。
摘要（英）：

An device comprises an extractor (53) having an outlet (71) at which a gas stream is sampled. The gas stream contains at least one hydrocarbon to be analyzed and at least one interfering compound. A transport line (54) is connected to the outlet (71) of the extractor (53) to transport the gas stream to an analyzer (55A), wherein the analyzer comprises a detector being able to measure at least one of the hydrocarbons to be analyzed contained in this gas stream. The device comprises a chemical reactor (141) located between the extractor (53) and the detector. At least a portion of the extracted gases is transported through the chemical reactor (141) where a selective catalytic reaction of at least one interfering compound is carried out without any substantial reaction of at least one of the hydrocarbons to be analyzed.
