Valve technology for distillation trays (such as FLEXIPRO floating valves)
The latest valve technology that simultaneously achieves energy saving, high efficiency, and high capacity.
The performance of a distillation column is greatly influenced by the contact efficiency between vapor and liquid on the trays, and the valve structure is a crucial factor directly related to energy efficiency, processing capacity, and operating range. Conventional sieve holes and T-type movable valves are effective, but they have challenges such as: - Vapor tends to be biased upward - Insufficient mixing near the deck - Limitations in stability during load fluctuations The latest FLEXIPRO floating valve features a design based on CFD analysis and actual machine testing, providing the following advantages: - Suppression of liquid entrainment with downward vapor flow - Improved mass transfer efficiency through strong mixing at the deck level - Uniformization of froth through forward extrusion action - Significant reduction of weeping at low loads with an extrusion molding structure - A wide operating range (approximately twice the turn-down of T valves) As a result, it is possible to achieve up to a 35% increase in processing capacity and energy savings compared to conventional valves. In the case of a diisobutylene separator, effects such as approximately 30% reduction in equipment weight have been confirmed through tower diameter reduction, tower height reduction, and tray spacing optimization, leading to CAPEX reduction.
