Oil and Gas Wastewater Treatment
Benefits of the Arvia Water Treatment system to the Oil and Gas industry:
Reduction in environmental footprint by reusing water
Simple and easy to operate with minimal manpower and maintenance
Scalable treatment to meet pressures to increase capacity and easily adjusted as requirements change
Water Use in the Oil and Gas Industry
The oil and gas industry is faced with several challenges including rising utilities prices, fluctuating oil prices, pressure to forever expand capacity and improve on environmental strategy. Water is a key component throughout the production process from onshore and offshore facilities to oil refineries and the management of wastewater is one of the main environmental challenges faced by oil and gas organisations.
Produced water is a by-product of oil and gas extraction and the composition is highly dependent on the type of rock the water has been in contact with as well as the chemicals used during the extraction process. The required treatment of produced water varies dependent on its intended purpose:
- Reuse for industrial process water or irrigation
- Surface disposal to the sea, subject to local environmental regulations and charges
- Injection into a disposal well
However, due to increasing environmental awareness and regulations, disposal to surface waters is becoming less commonplace and reuse is becoming more widely adopted in order to protect the environment and save money.
Oil and Gas wastewater treatment process
Arvia’s Nyex™ treatment processes are most successfully deployed as a final ‘polishing’ step in the oil and gas industry for the removal of the following:
- BTEX (refers to the chemicals benzene, toluene, ethylbenzene and xylene)
- NPDs (N,N′-Di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine)
- PAHs (Poly Aromatic Hydrocarbons)
- Organic acids (eg Benzoic acids)
- Alkyl phenols
- Dispersed hydrocarbons
- Biocides
Typically, Nyex™ would be part of a treatment train to remove the final recalcitrant organic contaminants and can be paired with a functionalised ion exchange to remove the inorganic contaminants. The systems are designed to treat the most complex wastewaters and are optimised for each application to preferentially treat pollutants of concern.
As a result, treated wastewater can be reused in the production process and therefore reduce freshwater intake.
Removal of BTEX and PAHs from Oil and Gas Wastewater
The Nyex™ range of wastewater treatment technologies are well suited for the final removal of persistent organic contaminants. BTEX compounds are among the most abundantly produced chemicals in the world...
