Membrane contactor applications

In a membrane contactor the membrane separation is completely integrated with an extraction or absorption operation in order to exploit the benefits of both technologies fully. Membrane contactor applications that have been developed can be found in both water and gas treatment. Several recently developed applications that have been introduced...

Off shore produced water treatment with pertraction

During the production of oil and gas also water is produced. This produced water contains dispersed and dissolved oil components. The impact of offshore emissions of produced water on the environment and the treatment of technologies for it are currently under discussion. Emission limits tend to become stricter. Ihe new membrane based extraction...

Novel Regeneration Methods For Strongly Acidic Metal Treatment Baths (Craft Regenabath): Final report of TNO acrivities

REGENABATH: Novel Regeneration Methods For Strongly Acidic Metal Treatment Baths

Flue gas treatment with membrane gas absorption

Dutch researchers from the TN0 Institute have developed a technique to carry out gas-liquid contacting operations using hollow fibre membranes in combination with an absorption liquid. The method known as membrane gas absorption, aims to combine the advantages of membrane technology (compactness, flexibility) with absorption processes ...

Flue gas treatment with membrane gas absorption

Membrane gas absorption is a new, efficient and flexible way to carry out gas-liquid contacting operations with hollow fibre membranes. Advantages of gas absorption membranes over conventional G-L contactors are: -High specific surface area and rapid mass transfer resulting in very compact and low weight equipment; -Gas and liquid flow are...

Membrane gas absorption environmental applications

More tight environmental legislation makes it necessary to develop new separation technologies that operate not only very efficient but also flexible. In many cases retro fit installations are required which put also constrains on volume and weight of the equipment to be installed. Membrane gas absorption is a new technolog with such interesting...

Integratie van pertractie met de regeneratie van absorptievloeistoffen

Pertractie is een nieuwe techniek voor de reiniging van proces of afvalwaterstromen verontreinigd met apolaire koolwaterstoffen zoals aromaten, gechloreerde koolwa-terstoffen of PAK's. Het pertractie proces is reeds succesvol op pilot plant schaal gedemonstreerd op verschillende industriële locaties. Aangetoond is dat regeneratie van het...

Membraangasabsorptie voor het beperken van emissies naar lucht

Voor het beperken van emissies naar lucht met membraantechnieken komt membraangasabsorptie het meest in aanmerking. Membraangasabsorptie is een nieuwe uitvoeringsvorm van een gasvloeistof contactapparaat. Hiermee is het mogelijk om zeer efficiënt stoffen als S02, HCl, H2S, CO2, NH3, O3 en waterdamp uit gasstromen te verwijderen. In de...

Membrane Gas Absorption

Membrane gas absorption processes are absorption processes utilising hollow fibre membranes as contacting media for gas and liquid flows. The principle of operation and engineering aspects are discussed, followed by discussion of a number of typical applications. Benefits in terms of operation, efficiency and costs are shown to exist for a...

Een luchtreiniger gebaseerd op gasabsorptie in membranen: Nieuwe ontwikkeling

Tabaksrook bevat enkele honderden chemische verbindingen, zowel in de deeltjes-als in de gasfase. In vertrekken waar wordt gerookt kunnen niet-rokers hinder en irritatie ondervinden door onvrijwillige bloot-stelling aan tabaksrook. Bestaande richtlijnen voor ventilatie van woningen en kantoren zijn onvoldoende om een goede luchtkwaliteit te...

Removal and reuse of sulphur dioxide from flue gas with a membrane absorber: final report

A membrane absorber is a new type of gas-liquid contactor based on hollow fibre membranes. The units display the following features: high removal efficiency, small volume, independent gas and liquid flow, simple operation, excellent upscale-upability, no entrainment, flooding or channelling. A development program has been carried out for the...

Membrane technology in carbon dioxide removal

The application of membrane technology in carbon dioxide removal was investigated for a number of different gasstreams. These gasstreams have been defined in the framework of the Dutch national programme on carbon dioxide removal and are typical of streams occurring in present and future electricity generation plants based on fossil fuels ...
