Abstract

In this work a new laser-hydrothermal apparatus is designed to evaluate nucleation of scale minerals at temperature up to 250°C, its reliability is proven by measuring induction time data of barite from 90°C to 250°C at various Saturation index (SI) values, with the objective that such a design would contribute to the scale-related research at extreme temperature. Background solution (e.g. 1m NaCl) in a borosilicate glass bottle was placed inside a hydrothermal reactor. GC oven was used for temperature control and a modified Nd-Fe-B magnetic stirrer under the oven was used for stirring. A PFA tubing was selected to be the part with contact with solution for corrosion control. Using a 0.5 ml sample loop in two separate 6-ways switch valves, Ba2+ and SO42-concentrated solutions were simultaneously injected into a background solution. After supersaturation was initiated, a laser beam penetrated through the sight glasses installed on the both sides of the reactor to record the turbidity change during the nucleation process. Induction time (tind) of Saturation index (SI) values from 0.34 to 1.02 was measured at temperatures from 90°C to 250°C. Data correlates well with data from previous laser test at 90°C in a regular beaker experiment. The induction time (tind), that is, how fast a supersaturated solution induces nucleation and crystal growth to form detectable turbidity, decrease with temperature at a fixed SI value. For example, tind of 93 minutes at 150°C decreases to about 2 minutes at 250°C under the the same SI value of 0.65, indicating that increasing temperature facilitates the nucleation process at certain supersaturation levels. This temperature impact can be attributed both by thermodynamics and kinectic aspects.

新型激光水热装置在高达250°C的温度下研究结垢矿物的成核和抑制作用
在这项工作中,设计了一种新的激光热液装置来评估温度高达250°C的水垢矿物的成核,通过测量90°C至250°C的重晶石在各种饱和指数(SI)值下的感应时间数据来证明其可靠性,目的是这样的设计将有助于极端温度下水垢相关的研究。本底溶液(如1m NaCl)装在硼硅酸盐玻璃瓶中,置于水热反应器内。采用气相色谱炉进行温度控制,炉下采用改进的钕铁硼磁力搅拌器进行搅拌。选择PFA管作为与溶液接触的部分进行腐蚀控制。在两个单独的6通开关阀中使用0.5 ml样品环,将Ba2+和so42浓缩溶液同时注入本底溶液中。过饱和启动后,激光束穿过安装在反应器两侧的视镜,记录成核过程中的浊度变化。在90°C ~ 250°C温度范围内测量了饱和指数(SI)值为0.34 ~ 1.02的诱导时间(tind)。数据与之前在90°C的常规烧杯实验中进行的激光测试数据具有良好的相关性。诱导时间(tind),即过饱和溶液诱导成核和晶体生长形成可检测浊度的速度,在固定SI值下随温度降低。例如,在相同SI值为0.65的情况下,150℃下93分钟的温度降低到250℃下2分钟左右,说明温度的升高有利于在一定过饱和水平下的成核过程。这种温度影响可以从热力学和动力学两个方面来解释。
