Embodiment 1
[0027] Still taking the annual processing of 50,000 tons of fusel oil as an example, the feed composition of fusel oil is 40% methanol, 6% ethanol, 2% isopropanol, 2% n-butanol, and 50% water. use as figure 2 As shown in the energy-saving rectification system and rectification method of the present invention, the total system needs to consume 16092.7kw of heat utilities, and the purity of the target product in the output of each tower does not decrease. Therefore, the rectification and purification energy-saving process of the present invention can save 23% of the thermal utility consumption of the whole system.
Embodiment 2
[0031] Still taking the annual processing of 80,000 tons of fusel oil as an example, the feed composition of fusel oil is 30% methanol, 10% ethanol, 5% isopropanol, 5% n-butanol, and 50% water. use as figure 2As shown in the energy-saving rectification system and rectification method of the present invention, the total system needs to consume 25111.1kw of heat utilities, and the purity of the target product in the output of each tower does not decrease. Therefore, the rectification and purification energy-saving process of the present invention can save 167% of the heat utility consumption of the whole system.
