Mesh structured is an important milestone in the development, such as corrugated packing by the pressure of the screen from film arranged, corrugated chip angle of 30 degrees or 50 degrees, adjacent the opposite direction the two corrugated films, filling in the tower, the next two 90-degree staggered stacked packing. With high efficiency, lower pressure drop and the flux of the advantages of large, products are AX, BX, CY type, commonly used in the difficult matter of separation and heat-sensitive vacuum distillation, atmospheric distillation and absorption process.
