Heat Transfer

Achieve optimal heat recovery in a kettle exchanger

Improve operations by avoiding buildup of sensible duty or by using baffles

Das, T., Consultant

Hydroprocessing units such as hydrotreaters and hydrocrackers, and other units such as vacuum distillation towers, visbreakers, fluid catalytic crackers, etc., involve considerable heat consumption and subsequent heat recovery. Heat recovery is mainly achieved with reactor effluents, fractionator pumparounds or overhead condensing vapors, depending on a plant’s process flowsheet. Invariably, this heat is used to preheat feed or generate steam. Some recoveries take place in a kettle-type heat exchanger. Kettle exchangers are mainly used for boiling in the shell side—e.g., steam generation. Normally, cold liquid entering the exchanger is close to its boiling point with respect t
