Abstract
Large volumes of Produced Water (PW) are being generated to surface facilities from underground reservoirs during the process of oil and gas extraction. PW is a mixture containing a complex composition of organic and inorganic pollutants threatening the environment. A huge load of salt in PW is mainly depending on the geological framework of the reservoir. In this study, we investigated a lab-scale evaporation-crystallization process coupled with ventilation for the recovery of valuables salt from PW treated by sand filtration. The results show two successive crystallizations of 96,62% and 92,25% Sodium chloride (NaCl), respectively. The effect of ventilation on the acceleration of the crystallization is noticeable.
