... energy requirements when compared to thermal oil recovery methods. Warm VAPEX Experiment The experiments for the investigation of warm VAPEX process were conducted in a rectangular packed model. Fig. 1 shows a schematic of the experimental setup used. Liquid n-pentane was pumped at constant flow rate...

... the annular space between two cylindrical pipes for constructing the slice-type sand-filled models. The cylindrical geometry makes the model more compatible with higher pressures without making them too heavy and cumbersome. Side by side Vapex experiments were conducted in the cylindrical models...

... observes several compositional changes during Vapex experiments in the laboratory, especially when working with conventional heavy oils such as those from the Lloydminster Area of Canada. Via physical model studies involving different heavy oils, it was seen that compositional changes occur in the oil...
