A system and method for distillation

A method for distillation, the method comprising:

• transferring a preheated feed stream to an analyser column configured to form a stripped vapor stream;
• compressing the stripped vapor stream in a first fan unit sufficient to form compressed vapor;
• transferring the compressed vapor to a rectifier column;
• rectifying the compressed vapor in the rectifier column sufficient to form rectified vapor;
• transferring the rectified vapor to a first evaporator unit;
• condensing one or more vapor components of the rectified vapor in the first evaporator unit sufficient to form rectified condensate, wherein a water vapor stream is formed during the condensation process in the first evaporator unit;
• and
• transferring the rectified condensate to the rectifier column and to a dehydration section.

A system for distillation, the system comprising:

• an analyser column configured for receiving a preheated feed stream and forming a stripped vapor stream;
• a first fan unit configured to compress the stripped vapor stream in one or more stages sufficient to form compressed vapor;
• a rectifier column configured to receive the compressed vapor sufficient to form rectified vapor;
• and
• a first evaporator unit configured to condense one or more vapor components of the rectified vapor to form rectified condensate, wherein the rectified condensate is transferred to the rectifier column and a dehydration section, and wherein a water vapor stream is formed during the condensation process in the first evaporator unit.
