La chromatographie d’extraction combine les avantages de l'échange d’ions et de l'extraction par solvants dont elle conserve le principe. L'agent extractant est fixé sur un support inerte, une poudre de Téflon ou de composé minéral disposée comme phase stationnaire dans une colonne. Cette méthode s’est peu développée, peut-être parce que la mise en œuvre de l'extraction liquide/liquide est plus rapide, sans doute aussi parce que les coefficients de distribution sont souvent à l'avantage des échangeurs d’ions et que les phases aqueuses sont polluées par le solvant. 1, record 1, French, - chromatographie%20d%26rsquo%3Bextraction

All [the] difficulties have been overcome with the development of the Degrémont-ECI (Continuous Ion Exchange) process which uses two types of apparatus generally combined in a single installation: The compacted bed system in which the resin is kept in a compact state during the fixing period by an upward flow of liquid pressing it against a top drainage system; The fluidized bed system in which the resin is held in suspension in an upward flow of liquid. Each ion exchange unit comprises: a fixing column, optionally a resin-raw liquid separation column, a regeneration column, a washing column. 1, record 2, English, - continuous%20ion%20exchange

Dimensionless number which like its reciprocal, the Bodenstein number, characterises the degree of dispersion, being zero for plug-flow and infinity for perfect mixing. It may be calculated experimentally from tracer studies.

The smaller the dispersion number, the less severe the backmixing. It is apparent that increasing linear velocity or bed depth will decrease the dispersion number and thus the backmixing. At higher conversion levels, the effect of backmixing on reactor performance is more severe than at lower conversions.

Le réacteur se présente sous forme d’une colonne garnie par un lit fixe d’enzymes immobilisées. On peut l'alimenter soit à flux descendant, soit à flux ascendant. Dans le cas idéal, toutes les molécules traversent le réacteur à la même vitesse et y séjournent donc pendant le même temps. On dit alors que l'on a un écoulement piston. Dans la réalité, il y a un certain échange de matière par diffusion, ce qui se traduit par l'apparition d’une distribution des temps de séjour(DTS). Cette DTS est caractérisée par le critère de PECLET :(...) Pour un écoulement piston, P est infini(D=0). Pour un réacteur parfaitement homogène P=0(D=[infini]). Le réacteur à lit fixe réel a un comportement intermédiaire entre ces deux cas extrêmes : P diminue d’autant plus que les phénomènes de diffusion sont importants et la courbe de DTS devient de plus en plus large. 1, record 6, French, - crit%C3%A8re%20de%20Peclet

Where the enzyme is expensive then the extra cost of immobilization, with its attendant promise of catalyst re-use, may be less than the cost of continually adding more enzyme to the reaction system. Thus the criterion of re-use of enzyme is important; so too is the stability of the immobilized enzyme in relation to the average residence time of substrate within the reactor. In order to obtain a high yield of product a balance must be struck between flow rate, reactor volume, and enzymic activity. High flow rates and small reactor volumes will give a small residence time and thus, for high product yield, will require a highly active enzyme preparation. Increasing the reactor volume will increase the residence time but will, at least in the case of the packed bed reactor, increase the quantity of immobilized enzyme required and thus the cost of the process. 1, record 13, English, - residence%20time

In an idealized reactor, all the fluid elements would spend the same time in the reactor. But in most real reactor systems, there would be a distribution of residence times of different fluid elements due to nonideal flow characteristics.

Le réacteur à lit fixe [...] se présente sous forme d’une colonne garnie par un lit fixe d’enzymes immobilisées. On peut l'alimenter soit à flux descendant, soit à flux ascendant. Dans le cas idéal, toutes les molécules traversent le réacteur à la même vitesse et y séjournent donc pendant le même temps. On dit alors que l'on a un écoulement piston. Dans la réalité, il y a un certain échange de matière par diffusion, ce qui se traduit par l'apparition d’une distribution des temps de séjour. 1, record 13, French, - temps%20de%20s%C3%A9jour
