Prayon Technologies (PRT)

Prayon Technologies (PRT), the licensing division of Prayon, is internationally renowned for its phosphate production technologies. Currently, plants fitted with Prayon technology are responsible for one third of worldwide phosphoric acid production. Prayon’s notable achievements include more than:

• 130 references in over 30 countries

• 120 production processes

• 65 validated phosphate rock types.

Experts at PRT dedicate themselves to designing easily operable and highly reliable phosphoric acid plants. This expertise comes from the company’s know-how and its track record with production plants gained during more than 70 years of experience. Prayon incorporates the very latest process developments into its plant designs to benefit all of the phosphoric acid producers the company works with.

PRT offers the widest range of technologies for phosphoric acid production. Each of the company’s five processes has its own characteristics. This allows Prayon to offer its partners successful tailor-made production options. The ability to deliver operationally successful phosphoric acid plants is reinforced by incorporating premium-quality equipment specifically designed by Profile, the process filtration and liquid equipment division of Prayon.

Alongside the traditional route for producing feed phosphates from high-grade phosphoric acid, Prayon now offers two cutting-edge technologies that can use low-grade phosphate rock as a starting material.

These innovative processes can significantly reduce production costs while generating feed phosphates of the same grade.

Prayon is aware that technological innovation will be vital for improving production processes to meet the needs of future generations. This includes developing technologies that are able to capture and use recycled raw materials. These will allow the phosphate industry to convert waste into valuable products while at the same time increasing the size of available phosphate resources.

PRT works closely with phosphoric acid producers to ensure they meet local environmental regulations. Reliable Profile-designed equipment, such as gas scrubbers and towers, enable businesses to reach high performance levels with close to zero emissions. The liquid bleed from these systems is either cleverly recycled into the process or concentrated to generate valuable co-products. Technologies are available to selectively remove deleterious and unwanted impurities (As, Cd, F, SO_4, Mg. etc.).

Prayon has also developed leaching technologies – chemical beneficiation processes – for magnesium (Mg), cadmium (Cd) and total organic carbon (TOC). These can be added as stages between the existing mechanical beneficiation and the phosphoric acid plant. These beneficiation innovations will enable phosphate rocks with high Mg, Cd and TOC contents to be used in the production of high-grade fertilizers such as DAP, while meeting environmental standards and optimising production efficiency.

Our in-depth process knowledge and understanding is the key to getting the best from a phosphoric acid plant. Prayon, through its wide range of services, always accompanies the owner at each and every stage of their project – starting by providing a tailor-made plant design all the way through to offering consultancy services during plant operations.

The company’s expertise encompasses:

• Lab to semi-industrial scale testing and validation

• Plant simulation training

• Technical surveys

• Operational excellence through data management and plant optimisation.

Profile

Expert guidance

In the demanding world of phosphoric acid production, equipment knowledge is vital, but it is the understanding of the entire process that truly makes a difference. That’s where Profile, a division of Prayon, excels, thanks to its ability to work hand-in hand with Prayon Technologies, the process experts.

Delivery, support & maintenance

Profile ensures that state-of-the-art practices are implemented by integrating our experts into your phosphoric acid plant project – from its inception to the end of the production cycle. This approach leverages the best industrial machinery available, as well as optimising Key Performance Indicators.

Our range of services include mounting supervision, site commissioning, and start-up assistance. Contracts are honoured, and quality products are guaranteed, thanks to the expertise of Profile’s field engineers.

Delivering the right service at the right time is also crucial. Our team’s rapid reaction in troubleshooting situations aims to save precious production time. We are dedicated to addressing any challenge swiftly – ensuring minimal disruption to your operations.

Annual audits are the cornerstone of proactive maintenance. Rather than waiting for issues to arise, our predictive maintenance approach anticipates maintenance needs, significantly reducing the need for reactive and remedial action. Through these audits, we share best practices, train production and maintenance teams, and optimise current equipment with the latest product developments.

Our Service, your benefits

Profile has a focus on enhancing operational performance with a commitment to:

• Increase production: Optimise processes and machinery for higher output.

• Product improvement: Utilise the latest advances to improve product quality.

• Cost reduction on total cost of ownership: Implement efficient practices to reduce overall costs.

• Avoid production stops: Proactive maintenance and rapid troubleshooting to prevent costly downtimes.

• Expert coverage: Benefit from the combined expertise of Profile and Prayon Technologies.

• Original quality spare parts: Ensure reliability and performance with our supply of original, high-quality spare parts.

Building partnerships

Profile believes in the power of partnership, as our success is built on trust and collaboration. We deliver not only equipment and services but also satisfaction and peace of mind.

Our unparalleled mechanical expertise is also supported by Prayon Technologies, who bring a comprehensive understanding of phosphoric acid production routes. This synergy ensures that Profile’s clients benefit from a holistic approach to process optimisation

Two new faces join the Profile team!

Profile recently welcomed two new colleagues to the team: Jean-Luc Vangramberen, Operations Manager and Giuseppe Giambarresi, Engineering Manager (see photo). Both bring complementary expertise that will further strengthen Profile’s development and structure, supporting its ambition to deliver premium-quality equipment to the phosphate industry worldwide.

Giuseppe Giambarresi, Engineering Manager, joined Profile in June 2025 to oversee the design excellence in Profile equipment. Supported by a team of specialised industrial designers, he develops new projects and customises our product portfolio – including Prayon filters, process agitators, gas scrubbers and Praysep™ droplet separators.

With a strong background in industrial design and mechanical engineering, Giuseppe is passionate about modernising the way Profile approaches equipment development. “My mission is to standardise in a rigorous way how our equipment is engineered, closely collaborate with the rest of Prayon’s team, keeping us as a premium-quality, innovative company and partner,” he explains.

Jean-Luc Vangramberen, Operations Manager, was recent integrated into the Profile team, and quickly embraced the division’s many ongoing projects. As Operations Manager, he now supervises field engineers and coordinates project implementation on site, ensuring Profile’s reputation for reliability and responsiveness continues to grow.

With more than 27 years of experience in metal manufacturing – particularly in stainless steel and special alloys – Jean-Luc brings a deep understanding of complex assemblies and operational excellence. “I’ve always been driven by customer satisfaction,” he comments. “Delivering high-quality equipment and ensuring smooth project execution is what motivates me every day.”
