ATV floating valve trays – an innovative patented product from XieLian Company. The technical approach behind ATV trays involves a comprehensive optimization of the tray structure and related components within the tower, thereby achieving a significant improvement in the performance of these trays. Its reliable performance has been proven in hundreds of commercial applications in distillation towers; not only is it dependable in operation, but its higher mass transfer efficiency and product yield also bring significant economic benefits to customers. Key Innovations in ATV Tray Technology – Optimization of the Floating Valve Structure • The trapezoidal shape of the valve surface allows for more fine dispersion of the gas flow, reducing mist entrainment. • The trapezoidal opening on the valve surface exerts a forward force on the liquid flow, reducing backmixing and enabling a more uniform distribution of gas and liquid. • The gas flow is emitted in two layers, facilitating better contact between gas and liquid, which helps improve separation efficiency and operational flexibility. • Floating valves with and without guide holes are arranged in a certain proportion, thereby eliminating mass transfer dead zones and liquid level gradients. • Reduced turbulence under the valve surface leads to a lower pressure drop across the tray. • By arranging floating valves with and without guide holes in appropriate proportions in different areas, it is possible to achieve the following outcomes: eliminating mass transfer dead zones on the tray, ensuring uniform liquid distribution, and improving production efficiency. Eliminating liquid level gradients on the tray also results in a more uniform gas-liquid distribution, enhancing production capacity. Key Innovations in ATV Tray Technology – Bubble Promoters • The gas flow loosens the liquid flowing out of the downcomer, making it easier to form bubbles. • It prevents leakage in the inlet area. • It ensures uniform gas flow distribution. • This helps improve production efficiency, production capacity, and operational flexibility. Key Innovations in ATV Tray Technology – Optimization of Feed and Extraction Structures • Design of the reflux distributor • Design of the feed distributor • Design of the transition section • Design of the extraction structure • Design of the reboiler return structure. Features of ATV Fixed-Valve Trays • Similar structure and performance to ATV floating valves, with relatively lower costs. • The operating range can reach 60% of the designed capacity. • No moving parts, no mechanical wear, and excellent anti-clogging properties. In addition to its high-performance ATV floating valve trays, Xielv also offers conventional trays such as floating valve trays, sieve trays, bubble trays, fixed-valve trays, tongue-shaped trays, and mesh trays. It also provides various types of trays and materials that customers may need, including integral trays, baffled trays, cross-flow trays, circular trays, horseshoe-shaped trays, jet trays, and high-speed trays.
