Environmental Services, Oil and Production Waste Management

NT&S has been providing environmental and oil production waste treatment services in Libya since 2006, having replicated its capabilities in Iraq in 2013.

Our services include:

  • Drilling and Production Waste Management (NORM, cuttings, fluids)
  • Oil Sludge Recovery and Treatment (Oil, Water, Solids)
  • Waste Transportation, Storage and Recycling
  • Drill Cuttings Treatment
  • Filtration Services

Drilling and Production Waste Management (NORM, Cuttings, Fluids)

NT&S Energy capabilities are focused on thorough project planning in order to ensure good handling and minimization of drilling and production waste. NT&S Energy ensures proper management of the waste so that they can be perfectly treated, stored and reused again as much as possible without having to dump excess amounts that could harm the environment. Our scope of treatment include bio remediation, thermal treatment, mechanical and chemical separation, fixation, desorption and/or incineration.


Oil Sludge Recovery and Treatment
(Oil, Water and Solids)

Taking in consideration the type of contamination and the categorization of the products to be treated, NT&S Oilfield engineers design fit for purpose reclamation processes based on international best practices and the specific condition of the site in order to put back the site in its original condition.


Waste Transportation, Storage and Recycling

NT&S Oilfield Services operate a large fleet of vacu-um trucks, centrifuges, and frac tanks, thermal de-sorption plant in order to efficiently remove and transport liquid, semi-solid and solid waste materials (both hazardous and non-hazardous) from surface impoundment, dip tanks and other chemical & fuel storage tank, treat and recondition the contaminated fluids or other waste in order to be reused.

Bioremediation

Bioremediation by the NT&S Environmental team presents a very cost-effective solution for remediation of hydrocarbon contaminated soils and waters, where conditions are suitable to achieve remediation in the required timeframe. The effectiveness of bio-remediation relies on the presence of conditions that encourage the growth of bacteria. Oxygen, nutrients and moisture are required for bioremediation of hydrocarbons in soil, and the process can be hampered by extreme temperatures, chemicals at toxic levels and salt.

Pre-treatment to remove free oil and salt water, will improve the efficiency of the solids bioremediation process.

In its simplest form, bioremediation involves placing windrows of soil, however in this case, the limited space and proximity of surface waters may mean that engineered cells are proposed, to allow control of the soil condition, in a smaller footprint.

Dryers and Centrifuge

NT&S has a range of dryer and centrifuge units for physical separation of waste an important first step in reducing volumes for handling and separating materials into predominantly oils, waters and solids to allow further treatment by other technologies. Sol-ids, oil and liquid effluent from the separators are very unlikely to meet the remediation target, but would be suitable for further treatment by bioremediation or thermal desorption and condensation.

Filtration Services

Our commitment to our customers is to provide on-site treatment of contaminated fluid (production water, drilling or completion fluids) to minimize the impact on the environment before disposal. We can re-move 99% of all hydrocarbons and heavy metals with our combined trailer mounted, DE filter press + Dual Cartridge units which is an economical, simple and robust system that:

  • Removes wide range of solid sizes and high dirt loads, up to 10000PPM
  • Treats high flow rates up to 10 – 25 BPM
  • Produce clean fluid up 2 micron absolute Beta5000 and NTU < 10NT

Equipment

Description
The APEX process separates oily wastes into three (3) components oil phase, water and cleaned solids. The plant nominal treating capacity is 20 tons of waste per hour. It offers a high operating capacity, low energy use, low carbon footprint, and a closed loop process.

Process
The waste is separated by reacting with the APEX chemicals in an aqueous solution followed by a series of operations removing and washing of the sol-ids and a separation of the oil and water phases. The process includes the next main steps: The first stage involves conditioning, screening and washing of oversize materials and free settling that allows for classification of the solids.

In the second stage the oily fines slurry is heat-treated and then separated into 3 phases by means of centrifugation. At the last step oil is collected for transport and the water containing chemical is circulated and reused in the process.

We have a number of accessible units available within our group including 2 currently in Kuwait.

Description
Wastes are heated between 90 to 560 °C to volatilize water and contaminants. A carrier gas stream transports volatilized contaminants to the treatment system.

Process
The process includes the next main steps: Screening to remove large objects, like rocks, cobbles and debris. Soil heating into a rotary dryer. Contaminants destruction into a thermal oxidizer at 900oC. Effluent gas stream treatment, filtration and neutralization. Soil conditioning.

Applicability
Volatile and semi volatile organic compounds as can be founds in Iraq OBM.
