Arab Client Orders DOING's six DY-15 batch tire pyrolysis units and two new type DY-15 waste oil distillation units

In December 2025, DOING, a manufacturer of pyrolysis and waste oil distillation equipment, announced a large order with a client from Kingdom of Saudi Arabia (KSA). The order includes six DY-15 batch tire pyrolysis units and two new type DY-15 waste oil distillation units. The client's business model is centered on tire processing and export, and this new project will enable them to have their own refining capacity to produce marketable fuel oil products.

DOING stood out during the contract signing process not only because of its equipment specifications, but also because of its proven, project-based capabilities to anticipate and mitigate the inherent risks of new refinery projects. Arab clients were most concerned about equipment reliability, especially given their lack of comprehensive refinery operation experience. Issues such as equipment stability, oil yield, environmental compliance, and safe operation by untrained personnel caused them considerable anxiety. Considering the client's situation, the DOING team did not adopt generic specifications but instead drew upon real-world case studies from similar projects in similar regions to address these concerns.

Operational handover and capability building: Recognizing the client's lack of experience, DOING outlined the support provided in previous projects, including operating procedures, staff training, and on-site commissioning plans. The DOING team provides on-site installation guidance, and engineers provide on-site training to local workers, including daily monitoring and basic troubleshooting methods, as well as a remote monitoring system for rapid troubleshooting. Furthermore, DOING has completed equipment installation and training in hundreds of countries and regions. This extensive practical experience greatly enhanced the Arab client's confidence in partnering with DOING.

Equipment Selection: The batch tire pyrolysis unit fully considers cumulative wear and corrosion issues. Key welds are reinforced using corrosion-resistant alloys, and it is equipped with multi-layered safety interlocking devices and emergency procedures based on actual failures. DOING's new solid catalyst waste oil distillation unit is based on extensive testing of various waste oils. The catalyst formulation has been repeatedly tested by the DOING technical team to ensure stability and high-purity output, with a recovery rate of up to 90%. Furthermore, its user-friendly control system reduces the learning curve for the team, making the complex catalytic process easy to operate.
