Metal Wire Gauze structured packing consist of proprietary designed metal wire mesh with corrugated sheets which are aligned and placed vertically.
The wire structures slopes are reversed in other sheets stacked with alternating 90 degree orientation of each layer resulting in inclined flow passages and a relatively high surface area. This allow thin liquid films to be continuously spread across the tower as liquid flows through the packing. Capillary action and high surface areas result in maximum exposure to high mass transfer efficiency, low pressure drop and large flow rate. TPU Gauze packing product series includes commonly used BX, CY types, generally applied in vacuum distillation, normal pressure distillation and absorption processes of matters hard to separate or thermal sensitive.
The key advantage of wire gauze structured packing is the high separation efficiency even at very small liquid loads along with its low pressure drop and small liquid hold-up, making it very suitable for distillation of thermally sensitive products.
BESTN wire gauze structured packing is supplied with surface areas: 250m2/m3, 500m2/m3, 750m2/m3, 1000m2/m3, 1200m2/m3. Surface area can be customized by adjusting the corrugation height level for your special requirement.
Features
