Directa Plus plc, a leading producer and supplier of graphene-based products for use in consumer and industrial markets, has announced the completion of industrial field testing of Grafysorber® at an oil treatment plant of OMV Petrom, a leading Romanian integrated oil and gas company and one of the largest in Southern Europe. The tests demonstrated that the deployment of Grafysorber improved the quality of water used for the injection process (further details provided below). The parties will now work together on the second phase of trials to expand the tests to treat a further contaminant.
Giulio Cesareo, CEO of Directa Plus, said: “Working with a leading organisation such as OMV Petrom, and in an industrial setting, is a tremendous endorsement of the strength of our Grafysorber® solution and its potential. We believe Grafysorber is a revolutionary material with a unique oil adsorption capability that has multiple environmental applications. We are delighted to progress to the next phase of testing with OMV Petrom and look forward to establishing a long relationship with them. This achievement further underpins the potential and importance of our recently-announced agreement with Sartec to develop innovative continuous process equipment to optimise Grafysorber utilisation for the oil & gas industry.”
The purpose of the field tests was to trial the ability of Directa Plus’ Grafysorber, which was used in a dedicated treatment facility on a site of OMV Petrom, to remove petroleum hydrocarbons from produced water so that it could be used as injection water. The field tests demonstrated positive results in the industrial decontamination of produced water. In particular, Grafysorber was successful in significantly reducing the concentration of total petroleum hydrocarbons (TPH) in the produced water to less than 0.5ppm.
Other features observed during the field tests included:
High versatility: Grafysorber performed well in both high and low TPH concentrations.
High efficiency: The TPH concentration was quickly lowered to the desired value.
Sustainability: Only a small amount of Grafysorber was required to achieve the desired value. In addition, the used Grafysorber proved to be reusable up to 4-5 times, which meant that no waste was generated during the test. This complements the eco-friendly nature of Grafysorber, which is a 100% carbon material and does not contain any plastic.
Full compatibility: Grafysorber was able to be used alongside other additives to improve water clarification.
