| 1 | Influences of different types of magnetic fields on HCFC-141b gas hydrate formation processes显示文摘In this study, visualizations and experiments are carried out on the influence of static and rotating magnetic fields on the characteristics of HCFC-141b gas hydrate formation, such as crystallization form, formation temperature and induction time. It has been found that a proper rotating magnetic field can considerably improve the low-pressure gas hydrate formation process, especially in increasing the formation temperature and shortening the induction time. The mor- phology of the gas hydrate formation appears rather complex and compact. However, a proper static magnetic field can make the gas hydrate crystal more organized, which will be benefit to heat transfer. | SHU Bifen MA Xiaolin GUO Kaihua LI Jianhong | 2004 | Science China Chemistry2004，47，5： | 14 |

| 5 | 管道内天然气水合物沉积实时监测系统研究显示文摘随着油气资源的开发逐渐向深海推进,天然气水合物在管壁处的沉积极易造成深海管道堵塞,严重威胁管道的安全运行,为此设计了一套水合物沉积层厚度变化的检测装置,监测水合物的沉积情况。该装置通过信号发生器产生激励,将管道内水合物沉积层厚度转换为电压信号,以实时监测水合物层生长过程。为准确描述管内水合物沉积层的实际厚度,基于水合物沉积层内部结构,构造了分形结构,通过水合物沉积层的电导率模型,将电压信号与管道内水合物沉积层实际厚度进行关联,最终由变化的电压信号得到管道内水合物沉积层的实际厚度。基于搭建的水合物沉积层厚度变化检测装置进行了管道内水合物沉积层成长实验,通过电导率模型将实验得到的电压信号转换为水合物沉积层厚度,判断管道内水合物是否生成及沉积情况。结果表明,在水浴温度为-2℃和-4℃的两种工况下,电导率模型转换的沉积层厚度与根据天然气消耗量计算得到的沉积层厚度相差20%左右,证实了此一体化设备能精确检测管道内水合物沉积层厚度。 | 曲顺利 刘翔 王武昌 | 2023 | 低碳化学与化工2023，48，2： | 0 |

| 7 | Methane hydrate crystal growth on shell substrate显示文摘Hydrate crystals growth on the surface of methane bubble(hydrate film)in pure water was studied by using a high-pressure visible microscope under the conditions of subcoolingΔT=5.44-13.72 K and methane concentration differenceΔC=2.92-8.19 mol·L^(-1).It was found the hydrate film is porous and the hydrate crystals grow towards the liquid phase on the film substrate.The crystal morphology and growth rate are affected byΔT andΔC.WhenΔT<8.82 K andΔC<4.12 mol·L^(-1),the hydrate grows into scattered columnar crystals,and the axial growth rate of the crystal gradually decreases.WhenΔT>8.82 K orΔC>4.12 mol·L^(-1),the hydrate crystals grow in dendritic shape,and the axial growth rate increases first and then decreases.The perimeter and area of the growing hydrate crystals were measured,and the fractal dimension of hydrate crystal under differentΔC andΔT was calculated.The results show that the fractal dimension of columnar hydrate crystal is greater than 3.When3.87 mol·L^(-1)<ΔC<4.20 mol·L^(-1) and 7.4 K<ΔT<8.8 K,the fractal dimension of columnar hydrate crystal is greater than 4;The fractal dimension of dendritic hydrate crystal is less than 3.WhenΔC>4.77 mol·L^(-1),ΔT<8.52 K,the fractal dimension of dendritic hydrate crystal is less than 2. | Xin Jiang Baojiang Sun Zhiyuan Wang Wantian Zhou Jiakai Ji Litao Chen | 2022 | Chinese Journal of Chemical Engineering2022，35，3： | 0 |
