Thermal process integration in the AVDU A12/2 crude distillation unit during winter operation

A pinch analysis of the AVDU A12/2 crude distillation unit processing 2 million tons of crude oil per year is made. A pinch retrofit of the recuperative heat-exchange system of the unit is performed. It is shown that the implementation of the proposed project will reduce the arbitrary energy consumption by 60%, which corresponds to a reduction in specific fuel consumption from 36 to 13 kg per ton of refined oil.
