Treatment of Oil-Sands Produced Water by Electrocoagulation
… However, the industry consumes a large amount of water, which is not economical. Significant capital and operating costs have been invested by the oil industries in the treatment of this contaminated water every year. Our objective is to develop new treatment solutions for the removal of …

Examination of produced water from the Al-Hamada oilfield, Libya.
Produced water is generated to the surface from oil production. Because of the complex composition of produced water (a mixture of different organic and inorganic compounds and residues of oilfield chemicals - added to aid oil water separation) and due to the outcome of increasing volume and effect …

Desalination of Produced Water via Gas Hydrate Formation and Post Treatment
… a two-step desalination process, in which produced water is cleaned by forming gas hydrate in it and subsequently dewatering the hydrate to remove the residual produced water trapped in between the hydrate crystals. All experiments were performed with pressure in the range of 450 to 800psi …

Pretreatment of Oilfield Produced Water using Ionic Liquids for Dissolved Air Floatation
… production of oil and gas, a larger amount of produced water (PW) will be generated. Produced water poses a risk to the environment, because it contains persistent toxic and carcinogenic constituents. The dissolved air floatation (DAF) process is the most widely used technique in the world for …

Treatment of Produced Water Using Dissolved Air Flotation (DAF) Technique and Ionic Liquids
As population grows, more water and oil resources are needed to make more products. In addition, more contaminants are also created due to daily uses. Consequently, environment protection will be a necessary duty for everyone. As produced water is a by-product from the oil production process, and …

Modeling Sensible Heat Driven Direct Contact Membrane Distillation Treatment of Oilfield Produced Water
… heat to drive DCMD treatment of oilfield produced water. Algorithms for performance prediction of instantaneous and counter-current DCMD flow were developed. These algorithms used equation-based models of heat transfer, mass transfer, concentration polarization, and counter-current flow to …

Predictions of produced water quality and quantity for spatially-distributed wells in Niobrara formation
… the oil and gas industry are the availability of water for well construction and disposal of the produced water. Produced water is typically only treated for a limited number of constituents, and common disposal options have been deep well injection, evaporation or discharge to wastewater …

Screening of Polymeric Membranes and Optimization of Operating Conditions for the Treatment of Produced Water
Produced water is the largest volume of waste stream obtained from oil and gas production. It affects both aquatic and terrestrial eco-systems if discharged directly into the environment. If the water is treated, it could represent a solution for water scarcity, and would reduce the impact on the …

Desalination systems for the treatment of hypersaline produced water from unconventional oil and gas processes
… associated with hydraulic fracturing is water resource management, as large quantities of water are both consumed and produced by the process. The management of produced water, the stream of water associated with a producing well, is particularly challenging as it can be hypersaline, with …

Improvement to hydrocyclone used in separating particles from produced water in the oil and gas industry.
Hydrocyclone is used to separate particles from produced water. It can be used in different industries, including oil and gas, water treatment and pharmaceutical (among others). The hydrocyclone can effectively separate particles larger than 10μm, but the efficiency is greatly reduced when the …

Screening of Microfiltration and Ultrafiltration Ceramic Membranes for Produced Water Treatment and Testing of Different Cleaning Methods
… a physical treatment method, was used to treat produced water (PW). Two ceramic microfiltration (MF) membranes and two ceramic ultrafiltration (UF) membranes were tested. The treatment target was to reach a contamination level suitable for further treatment by nanofiltration (NF)/reverse osmosis …
