A novel paralleling spiral packing with high efficiency used in sophisticated rectification is developed. It can solve the existing problem of efficient amplification effect of filler. The experiment results indicate that this packing has superior properties of higher efficiency and lower resistance than that of normal silk-packing, especially in mass transfer.
