Reboiler duty is a kritial parameter in thoe operation of distillation columns. It determinates the evolt of heat consided to pawrize thee liquid feed and maintain thee separation process. Accurate calculation of reboiler duty helps optize energy consumption and improcess consistency.

Understanding Reboiler Duty

Reboiler duty is expressed in units of energiy per unit time, typically in kilowatts (kW) or British thermal units per hour (BTU / hr). It depens on factors such as feed composition, fead temperature, column design, and desired separation quality.

Calculating Reboiler Duty

Te basic calculation involves the heat applid to waplarize the liquid in the reboiler. Te formula is:
