Abstract: A method for treating and disposal of fluid fine tailings utilizes two stages of thickening prior to disposal of the thickened tailings. The fluid fine tailings are adjusted to a sand-to-fines ratio of 0.5 to 1.3 using hydrocyclones or centrifuges in required. In a first stage of thickening a first flocculant is added to the fluid fine tailings which are fed to one or more conventional thickeners to produce a pumpable thickened tailings underflow having a solids content of between about 20 wt % to 40 wt %. The pumpable thickened tailings underflow is centrifugally pumped through a pipeline towards a disposal area. Adjacent the disposal area a second flocculant is added to the pumpable tailings underflow in a second stage of thickening to flocculate the tailings sufficient to produce a secondary thickened tailings underflow which when deposited has a solids content of about 50 wt % or higher at least one day after disposal. Alternatively, the second flocculant can be added prior to a paste thickener located adjacent the disposal area to further thicken the secondary thickened tailings underflow to a solids content of about 65 wt % for direct disposal at the disposal area.
Abstract translation: 用于处理和处理流体细尾矿的方法在处理增稠的尾矿之前利用两个阶段的增稠。 使用所需的水力旋流器或离心机将流体细尾矿调整至0.5至1.3的砂 - 细比。 在增稠的第一阶段，将第一种絮凝剂加入到流体细尾矿中，这些尾矿进料到一种或多种常规的增稠剂以产生固体含量在约20wt％至40wt％之间的可泵送的增稠尾渣下溢。 可泵送的加厚尾矿下溢通过管道离心泵送到处置区域。 在处置区域附近，在第二增稠阶段将第二絮凝剂添加到可泵送尾矿下溢中，以使尾矿絮凝足以产生二次增稠的尾矿下溢，当沉积的固体含量为约50重量％或更高至少一天时 处置后。 或者，可以在位于邻近处理区域的糊状增稠剂之前加入第二种絮凝剂，以进一步使次级增稠尾渣下沉至约65wt％的固体含量，以便在处置区域直接处理。

Abstract: A vapor blow through avoidance method, process and system for oil producing wells developed based on an innovative theory of vapor blow through pump. The system consists of casing gas remover, dynamic fluid level detector and downhole pump. Process includes adjusting casing gas remover and or pump rate based on result of comparison of the detected dynamic fluid level with the pre-set target dynamic fluid level; therefore, it prevents vapor in annular space blowing through pump and optimizes the well production. The avoidance system applies to single or group and horizontal or vertical wells.

Abstract: Embodiments of a feedwell discharge a solvent treated bitumen-containing froth feed to a froth settling vessel at a Richardson number less than 1.0. Feed is discharged from feedwell inlets to the vessel, either located at a center of the vessel or at a perimeter wall of the vessel along a substantially horizontal path across the vessel. The high velocity maximizes the horizontal path. As the velocity is reduced along the path and as a result of collision in the vessel with the perimeter wall or with feed entering the vessel from an opposing inlet, the feed separates into diluted bitumen and solvent which rises in the vessel for discharge as an overflow product and a waste stream, comprising water, solids and asphaltenes, which settles to the bottom of the vessel to be discharged as an underflow. A relatively uniform clarification zone forms above the inlets submerged in the vessel.
