Gas flaring is a common practice in the oil and gas industry, where droplets of flowback water with varying levels of dissolved salts (mainly composed of sodium and chloride) often become entrained in the flared gas. In this study, we examine the mixing state of the aerosol produced by a laboratory flare with and without entrained droplets of sodium chloride solutions. The resultant aerosol is cross-examined using several different methods, including: transmission electron microscopy (TEM), tandem measurements using a CPMA and a differential mobility analyzer (DMA), tandem measurements using a centrifugal particle mass analyzer (CPMA) and a single particle soot photometer (SP2), and Raman spectroscopy. A focus is placed on two-dimensional distributions of properties and the kind of morphological information contained therein. The TEM and CPMA-SP2 measurements both show that the majority of soot particles were internally mixed with salt, while TEM and CPMA-DMA measurements indicate that there are also a large number of isolated salt particles.

气体燃烧是石油和天然气行业的常见做法，其中含有不同浓度溶解盐（主要由钠和氯化物）的回流水液滴通常会夹带在燃烧气体中。在这项研究中，我们检查了实验室耀斑产生的气溶胶的混合状态，其中夹带和不夹带氯化钠溶液液滴。使用几种不同的方法对生成的气溶胶进行交叉检查，包括：透射电子显微镜 (TEM)、使用 CPMA 和微分迁移率分析仪 (DMA) 的串联测量、使用离心颗粒质量分析仪 (CPMA) 和单个颗粒的串联测量烟尘光度计 (SP2) 和拉曼光谱。重点放在属性的二维分布和其中包含的形态信息类型。
