An experimental methodology for inferring brine dissolution rate in monoethylene glycol (MEG) solutions at different temperatures using a webcam combined with a mathematical model is presented. The measurement system is designed to track the RGB (red, green, and blue) colour variations during the dissolution process. A dynamic model augmented with the population balance equation is applied to describe the dissolution process. Moreover, the dissolution rate is consistently related to the temperature and MEG concentration through the driving force based on the Gibbs energy and chemical affinity. The applied low‐cost measurement apparatus proved to be a useful resource for tracking the dissolution dynamics in a wide range of undersaturation.

使用低成本仪器和种群平衡模型推断NaCl在乙二醇水溶液中的动力学溶解

提出了一种使用网络摄像头结合数学模型来推断不同温度下单乙二醇（MEG）溶液中盐水溶解速率的实验方法。该测量系统旨在跟踪溶出过程中RGB（红色，绿色和蓝色）的颜色变化。用人口平衡方程扩充的动态模型用于描述溶出过程。此外，基于吉布斯能量和化学亲和力，通过驱动力，溶解速率始终与温度和MEG浓度相关。实践证明，所应用的低成本测量仪器是跟踪各种欠饱和状态下溶解动力学的有用资源。
