A reboiler is a heat exchanger used in a distillation column to generate vapor from the liquid feed at the bottom of the column.

• Reboilers can be classified into different types such as kettle reboilers, thermosiphon reboilers, and forced circulation reboilers.

• The type of reboiler used depends on factors like the properties of the feed, desired product purity, and energy efficiency.

• For example, a kettle reboiler is comm...read more

Logarithmic temperature difference is used to analyze heat exchangers in counter current and co current flow. Graph shows efficiency vs temperature difference.

• Logarithmic temperature difference is a method to analyze heat exchangers in counter current and co current flow

• In counter current flow, the temperature difference decreases along the length of the exchanger, resulting in a steeper curve on the graph

• In co current...read more

Pump flowrate calculation involves using the formula Q= ha

• Calculate the flow rate (Q) by multiplying the head (h) by the area of the pipe (a)

• Ensure units are consistent (e.g. meters for head and square meters for area)

• Consider factors like friction loss and pump efficiency in the calculation
