Abstract

Un procédé de déshydratation des résidus des sables bitumineux, en ligne et en temps réel, mesure en ligne un ou plusieurs parmi une concentration des matières solides, une teneur en argile et un débit dun flux de résidus, et une concentration de floculant dun flux contenant du floculant. Après avoir combiné une quantité de flux contenant du floculant à un flux de résidus, le flux de résidus enrichi en floculant est assujetti au cisaillement, basé initialement sur la mesure prise et mélangé dans un dispositif de cisaillement dynamique pour obtenir des résidus floculés. Des images ou des longueurs de corde des résidus floculés sont obtenus de façon continue en ligne et en temps réel avant une étape de séparation. Des signaux indiquant un état de floculation des résidus floculés sont dérivés en ligne et en temps réel à laide dimages, de longueurs de corde ou des deux, pour contrôler automatiquement, en temps réel, le cisaillement appliqué pour commander la capacité de déshydratation et la limite délasticité des résidus floculés.
