POREFLON™ Module Application Examples
■Small oil separators
Sumitomo Electric has launched a treatment system for oil-contaminated wastewater. Incorporating POREFLON™ Modules that are excellent in oil separation and alkali resistance, this system is designed to separate wastewater contaminated with a high level of oil from manufacturing processes into oil/suspended substances and filtrate without using chemicals.
This system helps manufacturers reduce environmental burdens and costs by reducing the volume of industrial waste and recovering alkaline cleaning and degreasing agents.
■Wastewater treatment at oil refinery in Taiwan
A large oil refinery in Taiwan uses POREFLON™ Modules to treat large amounts of wastewater. Seventy percent of the wastewater purified by POREFLON™ is reused as industrial water in the plant (water amount reused per day: 6,000 m3). POREFLON™ filters out contaminants such as oil and other organic substances stably and relatively free from clogging. Its chemical resistance allows itself to be cleaned of contaminants by the use of a strong alkali. The user appreciated and selected POREFLON™ due to the material’s durability and stable performance, which enables it to be used for a long period of time.
■Treatment system for water from oil fields
Interstitial water dug out when mining oil is contaminated with oil and turbid substances and is therefore required to be purified before it is released, reinjected into the ground, or reused.
Treatment of oil-field water is an area where Sumitomo Electric’s POREFLON™ Modules excel. We are conducting various tests for commercialization, aiming at its use in shale gas fields, currently the focus of attention. Sumitomo Electric is also working on development of an innovative oil-field water treatment system that incorporates an adsorption tower (marked with an asterisk in the figure) to perform pretreatment before the POREFLON™ Module. This innovative system performs advanced water treatment for reuse of water, uses no coagulants that require treatment of residue (insoluble substances separated by filtration or other processes), and treats oil-field water at low cost.
