Abstract:

The study presents the calculation of material and heat balances of an atmospheric-vacuum distillation unit for processing crude oil from the Komsomolskoye field with a capacity of 170 m³/h. Based on true boiling point (TBP) data, mass yields of product fractions within the boiling ranges n.k.–180 °C, 180–240 °C, 240–350 °C, 350–466 °C, and >466 °C were determined. The total material balance was closed at 142,970 kg/h (100%). Heat calculations for the atmospheric and vacuum furnaces were performed, and the total required fuel heat capacity was determined to be 32.687 MW. The calculated fuel gas consumption was 3,372.47 m³/h, corresponding to 33.7% of the available gas resource. The obtained results allow assessment of the technological and energy performance of the atmospheric-vacuum distillation unit under the specified operating conditions.
