中文摘要 | 本文乃探討一CMSMPR結晶槽於恆含固量及恆滯留時間操作時,溶液中雜質對晶體成長與成核之影響。文中闡示成長率與成核率在恆過飽和度與恆含固量兩種不同情況下之區別。若操作變數與二速率間之關係分別以冪次式表之,則可導出在恆含固量操作時,成長率與成核率之數學式,並藉以判別雜質對此二速率之影響。其變化則隨原速率方程式中過飽和度與雜質之冪次而定。文獻中報導當雜質存在時,成長率增加則成核率下降,有時則反之,此二種現象均能以推導之速率方程式解釋之。 |
英文摘要 | Utilizing power forms, in which the impurity concentration is included, to represent the growth and nucleation rates, a mathematical analysis is carried out to examine the impurity effects on the growth and nucleation rates in a continuous mixed-suspension mixed-product removal (CMSMPR) crystallizer under constant suspension density and constant residence time. The predicted various impurity behaviors are related to the kinetic orders of supersaturation and impurity concentration in the separate rate equations. Several systems studied in the literature follow the proposed models. |
