Metal wire gauze structured packing can be used in specialty chemical processing.
Metal wire gauze structured packing is an important milestone of the development of clear and neat filling. This kind of filling consists of arranged wire mesh pieces pressed into corrugation. Obliquity of corrugation is 45° or 60° and the neighbor two pieces are of opposite directions. When filling into the column, upper and lower filling trays cross by 90. It has advantages of high effectiveness, low pressure drop and large flow rate. This product includes BX, CY types, generally used 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.
Metal wire gauze structured packing can be used in specialty chemical processing.
Metal wire gauze structured packing has excellent transfer efficiency.
