As a potential replacement for CH4 hydrates in the petroleum industry and as an environment-friendly secondary refrigerant in the chemical industry, CO2 hydrates are proven for several industrial applications. Most of the studies on CO2 hydrates are mainly conducted in bench top facilities with very limited research work in the flow loop. A newly built high-pressure flow loop was used to investigate the effect of four parameters (initial pressure, temperature, flow rate, and liquid loading) on CO2 hydrate formation. The process of hydrate formation and its morphological evolution in the flow loop were observed visually and analyzed. The experimental results revealed that the gas consumption increased as the initial pressure increased; however, it decreased with the increase of the temperature, flow rate, and liquid loading. The effect of the induction time on CO2 hydrate formation was also analyzed in detail.

使用流路试验研究二氧化碳水合物形成的动力学
作为CH 4的潜在替代品石油工业中的水合物,以及化学工业中作为环境友好的二次制冷剂,CO 2水合物已被证明可用于多种工业应用。关于CO 2的大多数研究水合物主要在台式设备中进行,在流动回路中的研究工作非常有限。新建的高压流动环路用于研究四个参数(初始压力,温度,流量和液体负荷)对CO 2的影响水合物的形成。肉眼观察并分析了水合物在流动回路中的形成过程及其形态演变。实验结果表明,气体消耗随着初始压力的增加而增加。但是,随着温度,流量和液体载量的增加而降低。诱导时间对CO 2的影响 还详细分析了水合物的形成。
