吸收器内出现非等温吸收解析层的讨论

Discussion on Desorption Layer in the Nonisothermal Absorbing Tower

非等温吸收时，吸收器内存在着传质与传热的共同作用，通过传质、传热共同作用的数学模型，可求得吸收器内温度、组成沿接触面积的变化特性，从变化曲线可以找到吸收器内出现“解析层”的部位，宽度及原因。从而为防止“解析层”的出现提供依据。

Iin this paper,through presenting the mathematical model based on mass and heat transfer in the nonisothermal absorbing tower,characteristics Of change on temperature and composition were obtained along contact surface. From characteristic curve of change,position.thickness and reason of desorption layer were obtained.
