Abstract

Produced water quality has become an increasingly large area of concern for the oil production industry. A great deal of scientific research has been carried out to determine the consequences of exposure of produced water on the environment. Some of this research has given alarming results. Also, some of the toxic components in produced water may cause irreversible damage to the surrounding environment. Because of this potential risk, very considerable efforts oil separation technologies and researches are being expended. The corrugated plate interceptor is an efficient technique used for oil/water separation from 30 µm to150µm. In the present work, a two-dimensional mathematical model has been developed to investigate the effect of different Reynolds numbers (Re) and droplet diameter (d) on the corrugated plate interceptor performance (efficiency and catch length). The properties of water flow are solved using continuous phase governing equations (Eulerian approach). After that discrete phase equation of motion is solved, through the water moving stream (Lagrangian approach). The governing equations were solved between two corrugated plates using a finite volume FLUENT solver. The investigation showed that the separation efficiency is inversely proportional to the Reynolds number and directly proportional to the oil droplet diameter. It also shows that when the Reynolds number is less than 10 and the droplet diameter great than 30 µm the separation efficiency is almost 98%.
