甲烷水合物再汽化分解动力学模型建立
Kinetic model investigation of regasification of methane hydrate
摘要
Abstract
Hydrate regasification experimental study were performed for gas storage as hydrate, and the effect of temperature, dissociation pressure and hydrate quantity on hydrate dissociation rate were studied. The results indicated that hydrate dissociation rate decreased because of a buffering effect when the hydrate quantity was large in the reactor, but dissociation rate could increase by lowering dissociation pressure, and hydrate dissociation rate was controlled by the driving force of dissociation, which depended on heat transfer rate and dissociation pressure. According to the mechanism analysis of hydrate regasification, a model of regasification of methane hydrate was proposed based on heat transfer and equation of hydrate dissociation rate. The gas production rate of hydrate regasification was calculated by using the model and the results were basically in agreement with the experimental results. Analysis of disagreement between the experimental and calculated results was made.关键词
