The engineer designing an ion exchange column operation usually will prefer to work with the simplest kinetic model and linear driving force approximations. The weakness ofthis approach is that any driving force law only regards the momentary exchange rate as a hnction of the solute concentration in the bulk solution and the average concentration in the particle, neglecting the effect of concentration profiles in the particle

Often in multiple-effect evaporators the concentration of the liquid being evaporated changes drastically from effect to effect, especially in the latter effects. In such cases, this phenomenon can be used to advantage by staging one or more of the latter effects. Staging is the operation of an effect by maintaining

The solids-liquid separation process can be accomplished by filtration or centrifugation. Centrifuges magnify the force of gravity to separate phases, solids from liquids or one liquid from another. There are two general types of centrifuges: Sedimentation Centrifuges-where a heavy phase settles out from a lighter phase

Historically, sterile bulk pharmaceutical manufacturing processes, prior to filling operations, have followed general bulk pharmaceutical guidelines. As technology and equipment have improved

The widespread use of advanced control and process automation for biochemical applications has been lagging as compared with industries such as refining and petrochemicals whose feedstocks are relatively easy to characterize and whose chemistry is well understood and whose measure￾ments are relatively

The purpose ofthis chapter is to review various forms of solids dryers and auxiliary components. It is intended to be a practical guide to dryer selection (as opposed to the theory of drying, which is addressed in various technical manuals referenced in the bibliography). From a microscopic

一、 什么是越轨 社会成员偏离或违反现存的社会规范的行为。 注意：指现存的社会规范：为什么是现存的：（1）动态的。（2） 地域限制。 前面第二章文化部分学习过，社会规范是动态的，它随时间的变 化而变化，从而人们对行为是否违规的认定，也会发生变化。 因此：在理解该定义时，用现存限定一下较好
