Treatment of petrochemical wastewater and produced water from oil and gas

Abstract

Wastewater in petrochemical processes and produced water from oil and gas production remain a challenge for the industry to minimize their impact on the environment. Recent research and development of treatment technologies for petrochemical wastewater and produced water from oil and gas industries published in 2018 were summarized in this annual review. Great efforts and progresses were made in various treatment options, including membrane processes, advanced oxidation, biological systems, adsorption, coagulation, and combined processes.Practitioner points Treatment technologies for petrochemical wastewater are reviewed. Research development in produced water from oil and gas industries is summarized. Reviewed technologies include traditional, advanced, and innovative processes.

Photocatalytic degradation of oily waste and phenol from a local South Africa oil refinery wastewater using response methodology

“…Usually, these techniques work by gravity separation and are not effective without the application of coagulation which then increases the cost of chemical usage [21][22][23] . In this regard, several technologies have been proposed including; adsorption, biological systems, membranes, microwave-assisted catalytic wet air oxidation (hydrothermal oxidation), and advanced oxidation processes (AOPs) [22][23][24][25][26][27] . Unfortunately, some of these technologies are associated with many drawbacks including residual sludge generation, low efficiency, reaction rate, and operational conditions control within a specified temperature and pH for the treatment of ORW [28][29][30] .…”

Advanced Bioreactor Treatments of Hydrocarbon-Containing Wastewater

“…Importantly, the choice of a treatment method in each case is determined by the source of wastewater, the diversity and levels of contaminants, and the subsequent intended use of treated effluents. Recent developments in treatment technologies for petrochemical wastewater and produced water from oil and gas industries are reviewed by Wei et al [5]. Treatment of petroleum wastewater usually involves two stages, firstly, physical (mechanical) pre-treatment to remove free oil & grease fractions and suspended particles.…”

“…Several techniques that are used as advance treatment methods for reducing the effluent contamination level to allowable limits for discharge into water bodies include membrane filtration and electrodialysis [29,30], adsorption [31], biological systems [5], advanced oxidation [5] and electrochemical processes [32]. Of these, sorption methods are advantageous because their performance and cost efficiency are compatible with other techniques for petroleum removal, and sorbents are reusable after regeneration.…”

“…The complexity of the wastewater composition and stringent discharge limits require combinations of several treatment methods. There are several reviews published recently on the treatment of petrochemical wastewater [3][4][5] including biological methods [6,7]. This review focuses on advanced bioreactor technologies, including hybrid and integrated physico-chemical and biological systems.…”

Wastewater purification technology by two­stage treatment in electrical device of a compact local installation

“…A review of recent improvements in wastewater purification at oil refining facilities is given in [15,16], which describes various modern electrochemical technologies: membrane filtration, UV treatment and other methods of destabilization of sorption treatment emulsions.…”
