Applying process design software for capacity increase and revamp of distillation units

摘要

The paper presents the results of feasibility study for increase of crude processing capacity and improves of energy efficiency of crude oil distillation units. Results introduce that boosting up the distillation capacity was solved while keeping the flexibility of units for processing different type crude oils. Analysis of heat exchanger network resulted significant reduction in fuel consumption and in CO_2 emission (93 × 10~6 GJ year~(-1) and 3,030 tCO_2 year~(-1), respectively). Modification of furnace of one of the distillation units showed 63 GJ kt _(crude)~(-1) saving in energy and 4.5 tCO_2 kt_(crude)~(-1) decrease in emission.
