VWS MPP Systems Water Treatment for Removing Dissolved and Dispersed Hydrocarbons
VWS MPP Systems is a company of Veolia Water Solutions and Technologies (VWS) and part of the oil and gas division within VWS.
MPP Systems is a business activity specialized in developing, marketing, manufacturing and servicing water purification systems and water treatment systems based on macro porous polymers (MPP) for the offshore industry.
Water purification system – Macro Porous Polymer extraction technology
In the MPPE water treatment process, hydrocarbon-contaminated water is passed through a column packed with MPPE particles. The particles are porous polymer beads that contain a specific extraction liquid. The immobilized extraction liquid removes the hydrocarbon components from the process water. The purified water can either be reused or discharged.
Periodical in-situ generation of the extraction liquid is accomplished by stripping the hydrocarbons using low pressure steam. The stripped hydrocarbons are condensed and the separated from the water phase by gravity. The almost 100% pure hydrocarbon phase is recovered, removed from the system and left ready for recycling or disposal.
The condensed aqueous phase is recycled into the system. The application of two columns allows continuous operation with simultaneous extraction and regeneration. A typical cycle is one hour of extraction and one hour of regeneration.
Hydrocarbon removal – with MPPE to <1PPB
MPPE technology can reduce dissolved and dispersed hydrocarbons such as aliphatics, aromatics, polyaromatics and halogenated (chlorinated) hydrocarbons with 99.9999% removal. MPPE technology can be applied in offshore produced water, industrial process water, industrial wastewater and ground water in a wide variety of markets including the offshore, gas and oil, chemical, coatings and pharmaceutical industries.
MPPE to remove dissolved and dispersed hydrocarbons
Dissolved and dispersed components that can be removed from produced water include:
- Aromatics (benzene and xylene (BTEX))
- Polyaromatics hydrocarbons (PAHs)
- Naphtalenes, phenanthrenes, dibenzothiophenes (NPDs)
- Aliphatics; dispersed oil
- Hydrophobic parts of corrosion, scale and hydrate inhibitors and H2S scavengers
- TEOX / TEOC (total extractable organics)
- Halogenated hydrocarbons (such as chlorinated, bromated etc.)
- All other "hydrophobic" components (e.g. CS2, THT)
Other components that are also but partly removed (up to 80% depending on the conditions) are alkylated phenols, (ortho-, meta-, para-) cresols, higher alcohols and ethers.
MPPE can withstand complex produced water environments containing salt, methanol, glycols, corrosion inhibitors, scale inhibitors, H2S scavengers, demulsifiers, defoamers and dissolved (heavy) metals.
MPPE water purification system benefits
The main benefit of the MPPE water purification system is zero harmful discharge:
- MPPE reduces the environmental impact factor (EIF) with 95-99% (EIF is a produced-water management tool used by Norwegian industry)
- Separated hydrocarbons practically pure for use and re-use
- No waste stream/sludge formation
Ideal for upstream process integration, MPPE is a highly compact water purification system that is also robust, reliable, fully automated, remote controllable (via laptops and mobile phones), easy to operate and flexible. The MPPE material performance is guaranteed during the operational life of the unit at a fixed annual fee irrespective of the number of changes of the MPPE material.
MPPE ensures extremely high separation performance, proven competitiveness compared with air stripping / activated carbon, steam stripping and bio-treatment systems. MPPE’s energy consumption is 50 times lower than standard steam stripping.
MPPE water purification technology enabled anaerobic operations at ambient temperature without interference from dissolved iron, heavy metals, surfactants, salt and polar compounds. Biological fouling is prevented by the periodic in-situ regeneration afforded by steam.
Remote controllable mobile MPPE units are available for offshore field testing.
MPPE fits present and future emission regulations
Major multinational companies like TOTAL, NAM (Shell/Exxon), Hydro, Albemarle, Solvay, Gaz de France and Woodside have ordered and installed MPPE units onshore and offshore.
Offshore emission regulations in the North East Atlantic from <40ppm will be reduced to 30ppm. Total emissions must be reduced in 2006 with 15% compared to reference year 2000.
Future emission restrictions are also considered for dissolved hydrocarbons such as Aromatics (BTEX) and poly aromatic hydrocarbons (PAHs, NPDs) having a toxic impact on the environment. MPPE has a proven record in removing these toxic components with >99.99% and so contributes strongly to emissions with zero environmental impact.
The MPPE technology to be installed can be made flexible in such a way that it can cope with present and future regulations by tailoring the required performance at the lowest cost.
