H2S是一种有毒有害气体,故天然气在使用之前必须进行脱硫处理。而超重力旋转填料床因其在巨大的剪切力作用下,极大地强化了传质,大大增加了设备的生产能力,且装置尺寸远远小于传统塔设备。超重力技术与氧化还原法结合在天然气脱硫领域具有较好的应用价值。因此,建立一个实用可靠的传质系数模型,对超重力技术脱硫的研究具有重要意义。用甲烷和硫化氢的混合气模拟含硫天然气,并在某中试装置中用络合铁氧化还原法进行脱硫。根据所得的数据及旋转填料床中气液接触的特性,包括气体流量、液体流量、转子转速对体积传质系数的影响,采用Matlab进行相关数据拟合分析,得到传质系数经验模型。对经验模型进行分析对比,根据超重力装置中气液传质的特性对经验模型进行了改进,得到最终的传质系数经验模型。最后,将建立的传质系数经验模型与实验得到的数据进行对比验证。经分析对比,模型与实验数据吻合程度较高,平均偏差仅为0.12%,且该模型可以外推到其他体积与该超重力装置近似的装置,但气体流量应为1~10m3/h,液体流量为0.1~1 m3/h,转速为100~1 500 r/min。As the H2S in natural gas has toxicity, desulfurization is necessary before use of natural gas. Because of the huge shear stress of rotating packed bed, it will greatly improve the transfer rate coefficient and greatly increase the production capacity of the device. The device size is much smaller than conventional tower. High gravity technology combined with redox has good application value in the field of natural gas desulfurization. So establishing a practical and reliable mass transfer coefficient model is important for desulfurization of high gravity technology. The data in a pilot plant by chelated iron desulfurization redox has been got with a mixture of methane and hydrogen sulfide simulations of natural gas. According to the data and characteristics of gas-liquid contact in rotating packed bed, the effect of gas flow rate, liquid flow rate and rotor speed on volumetric mass transfer coefficient were studied. Using Matlab to fit analysis related data, the empirical models of mass transfer coefficient were obtained. Finally, comparisoning the mass transfer coefficient empirical model and experimental data, the analysis and comparison results showed that the model has high degree of agreement with the experimental data, and the average deviation is only 0.12%. The model can be extrapolated to other similar device which has similar volume with the high gravity device, but the gas flow should be in the range of 1-10 m3/h, the liquid flow of 0.1-1 m3/h, and the speed of 100-1 500 r/min. H2S is a toxic and harmful gas, so natural gas must be desulfurized before use. Due to its huge shearing force, the super-gravity rotating packed bed greatly enhances the mass transfer and greatly increases the production capacity of the equipment. The size of the device is much smaller than that of the traditional tower equipment. The combined application of gravity technology and redox has good application value in the field of natural gas desulfurization. Therefore, to establish a practical and reliable mass transfer coefficient model is of great significance to the research of desulphurization by over gravity technology. Sulfur gas is simulated with a mixture of methane and hydrogen sulfide and desulfurized using a complex iron redox method in a pilot plant. Based on the obtained data and the characteristics of gas-liquid contact in the rotating packed bed, including the effects of gas flow rate, liquid flow rate and rotor speed on the mass transfer coefficient, Matlab was used to conduct the fitting and analysis of related data to get the empirical model of mass transfer coefficient. The empirical model is analyzed and compared. Based on the characteristics of gas-liquid mass transfer in the super gravity device, the empirical model is improved, and the final empirical model of mass transfer coefficient is obtained. Finally, the established empirical model of mass transfer coefficient is compared with the experimental data. After analysis and comparison, the model is in good agreement with the experimental data, and the average deviation is only 0.12%. The model can be extrapolated to other devices with similar capacity to the super gravity device, but the gas flow rate should be 1 ~ 10m3 / h. Flow rate of 0.1 ~ 1 m3 / h, speed of 100 ~ 1 500 r / min. As the H2S in natural gas has toxicity, desulfurization is necessary before use use natural gas.
