MACRO POROUS POLYMER EXTRACTION (MPPE)

Veolia Water Technologies MPP Systems has developed a one step process that will remove both dissolved and dispersed hydrocarbons from water.

Macro Porous Polymer Extraction (MPPE) can reduce organic concentrations in contaminated water from thousands of ppm to low ppb levels in order to meet discharge limits. These turnkey systems offer guaranteed performance at fixed annual costs.

 

Industries

  • Offshore gas/condensate/(F)LNG produced water
  • Shale oil and shale gas produced water
  • Oil & gas downstream
  • Chemical/Specialty chemical
  • Pharmaceutical
  • Coatings/Resins
  • Electronic Industries

 

Applications

The MPPE technology is applied in water streams where toxic constituents are present. Therefore the main applications are in:

  • Offshore Gas/condensate/(F)LNG produced water
  • Shale oil/ shale gas produced water
  • Industrial waste and process water
  • Groundwater Remediation

 

Basically the MPPE technology removes the toxic content of the water streams and creates a discharge that is Zero Harmful to the environment.

In Onshore (waste-, process-, groundwater) and near shore applications very often additional BOD/COD requirements limits are required by local legislation. In such situations the MPPE technology is combined with a tailor made bio treatment to achieve the total BOD/COD discharge requirements at most competitive costs.

Where ever possible we aim at combining both, waste- and groundwater treatment in one MPPE unit. In real life the toxic hydrocarbons that are present in the wastewater are very often also present in the groundwater due to historical spills. In this way the investment into one MPPE unit can be optimized.

 

Gas/Condensate/ (F)LNG Produced Water

MPPE for Zero Harmful Discharge

MPPE removes dissolved and dispersed toxic hydrocarbons:

  • Aliphatic (dispersed oil)
  • Aromatic (BTEX)
  • Polyaromatics (PAHs)
  • NPD (Naphtalenes, Phenanthrenes, Dibenzothiophenes)
  • Toxic (Hydrophobic) constituents of field chemicals (e.g. inhibitors)

 

100% water and hydrocarbon recovery:

  • Separated hydrocarbons practically pure for (re)use
  • No waste stream/sludge formation

 

Robust and can withstand:

  • Salt, methanol, glycols
  • Corrosion inhibitors
  • Scale inhibitors
  • H2S scavengers
  • Demulsifiers
  • Defoamers etc.
  • Dissolved (heavy) metals

 

Industries:  Gas (F)LNG worldwide

MPPE is applied in countries with aware environmental legislations. Currently MPPE units are operating in the North East Atlantic (OSPAR area), Norway, The Netherlands, and Australia.

Clients: Shell, NAM (Shell/Exxon), Total, Statoil, Woodside, INPEX

Groundwater Remediation

Toxic hydrocarbons in groundwater can be found dissolved in water diffused over the area. At higher concentrations they can be present as DNAPLs (dense non-aqueous-phase liquids) or LNAPLS (light non-aqueous-phase liquids) creating an enduring source of toxic contaminant supply to the water phase.

MPPE benefits:

  • Ideal for handling a broad range of toxic hydrocarbons (e.g. aromatics, PAHs, chlorinated/halogenated, PCBs, MTBE)
  • Able to cope with unexpected higher inlet compositions at no additional costs
  • No iron removal needed (anaerobic process)
  • Robust, can withstand e.g. Salts, humic acids, surfactants, heavy metals, dissolved/suspended solids, high/low pH etc.
  • No sludge formation (as with iron removal andbiotreatment)
  • Scope for combination with other ground- and also waste water streams in one unit
  • Has been succesfully applied in surfactant and alcohol

Macro Porous Polymer Extraction (MPPE) is a highly effective technology for removing dissolved and dispersed hydrocarbons from water by means of liquid-liquid extraction.

The extraction liquid is immobilized in MPP particles applied in a packed bed.

The MPPE system is fully automated, remote controlled with a guaranteed separation performance for the operational life of the unit.

 

MPPE Process Description

 

 

In the MPPE process, water containing hydrocarbons is passed through a column packed with MPPE particles. The Macro Porous Polymer particles contain a specific extraction liquid.

The immobilized extraction liquid removes the hydrocarbons from the water. Only the hydrocarbons, which have an afinity for the extraction liquid, are removed. The purified water can then either be reused or discharged.

Periodical insitu regeneration of the extraction liquid is accomplished by stripping the hydrocarbons with low-pressure steam. The stripped hydrocarbons and steam are condensed and the hydrocarbons are separated from the water phase by gravity.

The almost 100% pure hydrocarbons phase is recovered, removed from the system and ready for use/reuse. The aqueous phase (condensed steam) is recycled within the system. The application of two columns allow continuous operation with simultaneous extraction and regeneration. A typical cycle is one hour of extraction and one hour of regeneration.
