The packing has
advantages such as light, high capacity, low pressure drop, large
specific surface area, easy replacement, etc. It is widely used in unit
operations like rectification, absorption and extraction.
The material¡¯s heat
resistance reaches 100¡æ for PP and 150¡æ for PVDF. The packing sheet may
be perforated with small holes to increase mass transfer efficiency. If
the separation requirement is not high, it needs no perforation on the
surface. In this way the sheet stiffness can be ensured.
