Column Trays

Many traditional column trays struggle when dealing with viscous media like coal tar or polymer solutions, leading to significant drops in separation efficiency. However, Sutong's Gradient Aperture Fixed Valve Trays are specifically engineered for such challenges. Our innovative design features valve holes optimized for different viscosity levels – larger in low-viscosity areas and smaller where viscosity is higher. This ensures uniform vapor distribution and sustained high efficiency. Furthermore, our trays are treated with a specialized oleophobic coating that actively repels viscous fluids, preventing build-up and maintaining optimal performance. In fact, our technology has been proven in demanding coal-to-oil projects to retain over 95% efficiency, significantly outperforming standard trays which often drop below 70% in similar conditions. Choose Sutong for reliable separation, even with the toughest media.

Strong foaming in systems can cause significant product loss and contamination due to mist carry-over. To effectively combat this, Sutong employs a robust combination of technologies in our column trays. We integrate a Triple-Stage Swirl Vane Demister which efficiently captures fine liquid droplets as small as 50μm, dramatically reducing carry-over rates to as low as 1.5%. Complementing this, our Rectangular-Trapezoidal Guide Floating Valves are designed with guide baffles that actively prevent the formation and aggregation of large, troublesome bubbles. This dual-action approach ensures minimal product loss and high product purity. Our technology's effectiveness is validated in critical applications like ship exhaust gas cleaning, where it meets the stringent IMO 2020 standards with a desulfurization efficiency of 98.5%. Trust Sutong to deliver clean and efficient separation, even in foaming environments.

We understand that modifying existing tower support structures can be a major concern during revamps, involving significant costs and extended downtime. Sutong's Modular, Split-Type Design for column trays directly addresses this challenge. Our trays are engineered with support beam spacing that is fully compatible with both ASME and EN standards, with an extremely precise tolerance of just ±2mm. This means you can often replace your old trays with our advanced designs without the need for costly structural alterations. Furthermore, we provide detailed design drawings, including 3D models, within just 48 hours, allowing for swift planning and execution. Our commitment to seamless integration is highlighted by a project for Mitsubishi Japan where we retrofitted their U-shaped floating valves in just 4 weeks – a fraction of the 12 weeks typically required by other solutions. Upgrade your tower with Sutong for a faster, simpler, and more cost-effective revamp.

Operating in extreme conditions like cryogenic air separation or highly corrosive environments demands exceptional material integrity. Sutong rises to this challenge by employing advanced materials like Hastelloy C276 reinforced with laser micro-cladding. This high-performance alloy offers superior resistance to pitting corrosion, boasting a Pitting Resistance Equivalent Number (PREN) greater than 40 and certified under ASTM G48. It also maintains its structural integrity at ultra-low temperatures, with a leakage rate of less than 0.01% at -196℃. This ensures reliable and safe operation in even the most demanding applications. Our material selection is further validated by certifications from leading industry bodies like Det Norske Veritas (DNV) for LNG projects. Choose Sutong for column trays built to last, no matter the extreme conditions.
