Application de la mesure de viscosit\u00e9 dans la concentration de liqueur noire<\/h2>\n\n\n\n

Premi\u00e8rement, le<\/strong> processus<\/strong> de r\u00e9cup\u00e9ration est optimis\u00e9<\/strong> en br\u00fblant les<\/strong> solides concentr\u00e9s dans une<\/strong> chaudi\u00e8re de r\u00e9cup\u00e9ration. De ce fait, le contr\u00f4le de la viscosit\u00e9 <\/a>est imp\u00e9ratif afin de stabiliser la concentration de la liqueur noire; avant d\u2019entrer dans la chaudi\u00e8re de r\u00e9cup\u00e9ration.
Une concentration instable de liqueur noire g\u00e9n\u00e8re des d\u00e9chets; une surconsommation; augmente les co\u00fbts de l’approvisionnement en \u00e9nergie; les \u00e9missions de fum\u00e9e; et oblige \u00e0 des op\u00e9rations de maintenance fr\u00e9quentes engendrant des temps d’arr\u00eat qui baissent la productivit\u00e9 globale de l\u2019usine.<\/p>\n\n\n\n

Deuxi\u00e8mement, l’installation d’un viscosim\u00e8tre de process en ligne apr\u00e8s \u00e9vaporateur ou concentrateur; permet de r\u00e9guler l\u2019extrait sec de liqueur noire, qui suivra le cycle d\u2019op\u00e9rations s\u2019il est dans les param\u00e8tres optimum de combustion, ou retournera dans la colonne d’\u00e9vaporation dans le cas inverse.
Le viscosim\u00e8tre MIVI <\/a>ne d\u00e9rive pas dans le temps. Mont\u00e9 dans n\u2019importe quelle position \u00e9tudi\u00e9e sp\u00e9cifiquement \u00e0 chaque process pour \u00e9viter le colmatage. La gamme de viscosit\u00e9 du capteur est adapt\u00e9e aux diff\u00e9rentes compositions de la liqueur noire.<\/p>\n\n\n\n

Troisi\u00e8mement, l’optimisation des chaudi\u00e8res de r\u00e9cup\u00e9ration par le contr\u00f4le de la viscosit\u00e9 indique une r\u00e9duction de 3 \u00e0 20% de la fr\u00e9quence des lavages \u00e0 l’eau. L’installation du viscosim\u00e8tre de process MIVI contr\u00f4le avec pr\u00e9cision de niveau de concentration de la liqueur noire et standardise son approvisionnement pour une combustion efficace. Finalement, des \u00e9tudes ont d\u00e9montr\u00e9 que le suivi r\u00e9gulier de la viscosit\u00e9<\/strong> de la liqueur noire dans un proc\u00e9d\u00e9 global d’optimisations. Ce qui peut ainsi repr\u00e9senter pour certaines usines des \u00e9conomies de plus de 1 million de dollars par an.<\/p>\n\n\n\n
