Using efficient, low-resistance packing or trays to reduce the operating temperature of the tower and thereby save energy； 2. The multi-effect distillation method is employed, similar to multi-effect evaporation, to utilize secondary steam in order to achieve energy savings ； 3. The principle of heat pump compression is employed to make further use of the secondary steam; there are methods using mechanical compressors and steam jet pumps to compress the secondary steam, increasing its pressure so that it can be utilized ； 4. The coupled distillation method is employed to link the secondary vapors from different columns together, based on the varying operating temperatures of each column, thereby allowing the secondary vapors from certain columns to be utilized in other columns. Others include ensuring proper insulation and reasonably controlling the reflux ratio
