Application of vapex process for light crude oil

The objective of this study is to investigate the applicability of Vapex process on Garzan crude oil. Experiments were performed with Hele-Shaw cell using two different solvents (propane and butane) at three different injection rates (20,40, and 80ml/min). For both Vapex solvents, oil production rates increased with injection rates for Garzan crude oil. Instantaneous asphaltene rate for Garzan oil showed fluctuated performance with propane solvent. Butane showed almost constant degree of asphaltene precipitation. For asphaltene precipitation, propane gave better results than butane in almost all injection rates for Garzan crude oil.
