| Abstract | 研究了盐水体系中环戊烷-甲烷水合物生成过程中的温度变化,分析了体系的热量损失。在初始温度为4.0℃和压力为8.5MPa的条件下,考察了不同气液比R(gl、环戊烷与水体积比rv和盐度w(NaCl对釜内最高温度T(max的影响。实验表明,T(max受rv和w(NaCl影响显著,而受R(gl影响较小,其中T(max随rv的增加呈现先增后减的趋势,随w(NaCl的增加则呈现递减的趋势。在R(gl为0.786、rv为0.556的条件下,w(NaCl为0%、3.5%、6.0%和7.0%盐水体系的T(max分别为21.3℃、12.6℃、11.5℃和10.7℃。由热量分析发现,体系的主要热量损耗表现为体系向环境中的散热,加快釜内水合物生成速率和提高体系绝热效果,有利于提高水合物生成热的热量有效利用率,从而提高T(max。 |
| Other Abstract | The system temperature change and heat loss in the process of cyclopentane-methane binary hydrates formation in the system containing brine at 4.0℃ and 8.5MPa were investigated. The values of the maximum temperature (Tmax were measured under different conditions, including gas/liquid volume ratio (Rgl, cyclopentane/water volume ratio (rv and salinities of the solutions (wNaCl. The experimental results show that rv and WNaCl have a significant influence on Tmax while Ro has a little effect on Tmax. The optimum Ro and rv are 0.786 and 0.556, respectively. Under the optimized conditions, the values of Tmax are 21.3℃, 12.6℃, 11.5℃ and 10.7℃ obtained in the brine system with WnaCl of 0, 3.5%, 6.0% and 7.0%, respectively. In addition, the heat analysis indicates that the major heat is consumed via heat radiating from the inner reactor to the outside cold environment. Therefore, accelerating the formation rate of hydrates in the reactor and improving the insulation properties of insulating layer are helpful to enhance the heat efficiency and Tmax in the process of the cyclopentane-methane binary hydrates formation. |
