Extraction technology to produce high-quality process oils in the Middle East
The new solvent extraction plant for the production of eco-friendly, high-quality process oils (TDAE, Treated Distillate Aromatic Extract) based on the EDL license allows customers to meet the latest environmental and quality requirements and to expand their product portfolio. The new solvent extraction plant will be designed under consideration of new resource-saving technologies.
As part of the licensing, EDL carries out the required laboratory tests and prepares the PDP (Process Design Package) for the plant and the FEED (Front End Engineering Design) for the extractor section.
EDL Test Facilities
The required process parameters and the optimum process conditions are determined in EDL’s own test facilities based on customer and product requirements as well as the hydraulic data of extractor internals. This allows a safe design of the plant for the entire range of feedstock available at the customer.
High-quality products in two extraction steps
The basic principle of EDL’s technology to obtain high-quality base and process oils from vacuum distillates (lube cuts) and deasphalted oil (DAO) is a two-stage extraction process.
In a second extraction stage using a proprietary solvent mixture, DAE and RAE are transformed into high-quality process oils such as Treated Distillate Aromatic Extract (TDAE) and Treated Residual Aromatic Extract (TRAE) having a low level of polycyclic aromatic hydrocarbons (PCA).
Eco-friendly atoxic process oils for the tire industry
DAE and RAE are required as tender oils to produce rubber products, such as tires, hoses, belts, cable insulation, floor coverings
In addition to solvent extraction EDL also grants licenses for other technologies to produce base oils, process oils, waxes and other high-quality specialty products, such as DEWAXING / DEOILING, MICRONIZATION,
"Granting the license for the two-stage extraction technology gives proof of the fact that customers rely on our eco-friendly technologies. By further expanding our technology portfolio, for example with
