Oil Sludge Plant with Three-Phase Separation Approved: Estedama and Saudi Aramco Visit Flottweg Together

Estedama Environmental Solution is a company based in the eastern region of Saudi Arabia that specializes in providing a wide range of industrial and environmental services, including the treatment and recycling of hazardous industrial waste. In June 2023, the company purchased an oil sludge plant with a pretreatment system, three-phase separation system, and conveyor technology to handle the separated phases from the separation technology specialist Flottweg. In total, the order included an oil sludge plant with several pretreatment stages, a chemical dosing system, a Flottweg Tricanter® three-phase separation system, and storage facilities for the separated phases. The fully mobile plant was completed and subsequently approved during Estedama's visit to Vilsbiburg in January 2024. The commissioning of the oil sludge plant is expected to take place in the second quarter of 2024.

Oil Sludge Plant to Be Used at Saudi Aramco in the Future

The mobile container plant planned by Flottweg and Estedama was tailored to individual requirements and will be used for Saudi Aramco soon for oil sludge recycling. Saudi Aramco is the largest oil company in the world. The mobile plant will now make it possible for oily sludge to be separated into three main parts: oil, water, and solids. This will not only conserve resources, but will allow for oil to be recovered at the same time, which is a positive thing when it comes to environmental concerns. Flottweg’s Tricanter®, which enables efficient three-phase separation, is at the center of the plant.

Visit to Flottweg’s Headquarters and Production

Alongside Saudi Aramco, Faleh Aldossary, General Manager at Estedama Environmental Solution, visited the separation technology specialist to give the plant's final acceptance. Faleh Aldossary and the visitors from Saudi Aramco gained a glimpse into the cutting-edge production of the separation technology specialist in order to get a picture of the company's quality and expertise themselves and be able to visit the entire oil sludge plant. For Estedama, this is already the second project to be implemented with Flottweg. After purchasing the first oil sludge plant with a Tricanter® Z4E and a separator AC2006, the container plant has now been upscaled.

Michael Hohenthanner, who coordinated and implemented the project as project manager, is satisfied with the progress: “The planning and implementation of the mobile container plant for oil sludge recycling has gone extremely well in recent months. In collaboration with Estedama, we have developed an advanced solution for separating oil, water, and solids from sludges from ponds, lagoons and storge tanks. During the final acceptance on site together with Estedama and Saudi Aramco, the visitors were very excited about the produced plant. Follow-up orders placed, such as for a mobile skid system with a Tricanter Z6E, chemical dosing system, pretreatment tanks, and pump stations to be produced for Estedama in the coming months, are proof of our successful cooperation.”
