Corrugated packing: the development of structured packing is an important milestone, which fill the screen by the pressure into a sheet arranged in corrugated, corrugated sheet angle of 30 degrees or 45 degrees, the two adjacent corrugated sheet in the opposite direction, filling in the tower When installed, up and down two 90-degree staggered stacked packing. With high efficiency, low pressure drop and flux characteristics of products are BX, CY type, commonly used in heat-sensitive substances difficult to separate and vacuum distillation, atmospheric distillation and absorption process.
