“…The most common brine treatment technologies in a ZLD system are brine concentrators and brine crystallizers [25,26]. In our previous work Salih et al [27] and Salih and Al-Alawy [28], the treatment of oilfield produced water from the East Baghdad oilfield with TDS = 86 g/l using three stages of the ZLD system namely oil skimming, coagulation/flocculation, and forward osmosis processes were studied. The best temperature and time for oil skimming were 40 °C and 2.5 h. which gave 95.8% removal for oil content.…”

This study investigated the application of the crystallization process for oilfield produced water from the East Baghdad oilfield affiliated to the Midland Oil Company (Iraq). Zero liquid discharge system (ZLD) consists of several parts such as oil skimming, coagulation/flocculation, forward osmosis, and crystallization, the crystallization process is a final part of a zero liquid discharge system. The laboratory-scale simple evaporation system was used to evaluate the performance of the crystallization process. In this work, sodium chloride solution and East Baghdad oilfield produced water were used as a feed solution with a concentration of 177 and 220 g/l. The impact of temperature (70, 80, and 90 °C), mixing speed (300, 400, and 500 rpm), feed concentration (177 and 220 g/l), and time (0.5-9.5 h) on the crystallization performance for oilfield produced water treatment were investigated on evaporation rate and recovery. The recovery increased with increasing temperature and mixing speed while decreasing with an increase in feed concentration. Pure water and salts were recovered from the concentrated produced water, the recovery of pure water at 80 °C, 400 rpm, and 220 g/l feed concentration was 82.22 and 81.35% after 5.5 h for NaCl solution (i.e., simulated oilfield produced water) and oilfield produced water, respectively.

Recent Perspectives on the Management of Formation Water Generated from Hydrocarbon Reservoirs

et al. 2023

View full text Add to dashboard Cite

The water associated with oil and gas reservoirs is formation water (FW), which is generated at the surface during hydrocarbon production. The major challenges associated with the treatment of FW are higher contents of oil and grease, high salinity, suspended solids, organic pollutants, traces of heavy metals, and undesired microbes. To meet the stringent requirements for the usage and disposal of FW, various treatment methods have been developed and implemented in the oil industries for the sustainable management of generated FW from the hydrocarbon reservoir. This article aims to summarize the aspects related to the treatment of FW like the generation, available treatment methods, and prevailing challenges. The basics and working principles of individual methods have been described along with relevant examples for the treatment of FW. In addition, the combined/hybrid methods for the treatment of FW have also been discussed to improve overall efficiency. Hybrid methods have shown a better performance than conventional techniques and need to be implemented for effective treatment of the voluminous FW to meet stringent environmental standards for reuse and discharge.

Due to human indifference and reckless oily wastewater production from industry, environmental or ecological pollution has become a challenge for our planet. Oily industrial wastewater mostly released by oil fields, refineries, cars, palm oil sectors, and many others is one of the biggest dangers. Oil and water can be virtually completely separated using membrane-based technologies. However, these technologies still face challenges in upholding efficiency over extended periods due to membrane fouling induced by oil droplets mixing with the membranes. Therefore, to overcome these challenges, the creation of polymeric, ceramic, and metallic-based membrane materials with enhanced performance is the focus of research in this field. In this review, various published approaches applied for treating industrial wastewater by using Ceramic Membranes integrated with nanoparticles were focused initially. Then, a modified experimental procedure from the literature for wastewater treatment process by using ceramic membranes is discussed. The majority of studies indicate nearly total oil rejection and increased outputs. Silicon carbide (SiC), Titanium dioxide (TiO2), Aluminum Oxide (Al2O3), Iron Oxide (Fe2O3) Powdered Activated Carbon (PAC), Zirconium dioxide (ZrO2), Alumina powder (Al), Silica (SiO2), Graphene Oxide (GO), and Silver (Ag) are identified potential nanoparticles to mix with ceramic membranes for wastewater treatment application.
