Abstract
본 연구에서는 에너지 소비가 큰 원유증류공정을 대상으로 한 최적설계의 일환으로 장치비용과 운전비용을 최소화하도록 공정의 최적운전조건을 구하였다. 증류공정은 각 단위공정 사이에 상호연관성이 매우 크므로 각각의 단위공정에 대한 최적화를 수행한 기존의 방법과는 달리, preheat train, 상압 및 감압 증류탑과 경질 납사 안정기 등의 전체 증류공정을 대상으로 하여 동시에 최적화 작업이 수행되었다. 이를 통하여 pumparound 열량, 탑의 압력, 원유 예열공정의 온도 및 압력 등을 구하였으며 최적화의 결과치를 기존 공정의 경우와 비교하였다. 최적화의 경우 원유예열공정에서 약 20,000,000 Kcal/h의 에너지 절감을 가져올 수 있었으며, 연간비용을 목적함수로 고려하여 최적화 한 결과 연간비용은 10,649,000 US$/y에서 9,185,230 US$/y로 감소하여 14%의 비용을 절감할 수 있었다.
This paper considers the optimal operating conditions to minimize the annual capital and operating cost of a crude distillation unit, which consumes enormous energy. Reflecting on the complexity of intervention and interconnection among each unit, optimization task was carried out for the whole crude distillation unit including preheat train, atmospheric/vacuum distillation column, light naphtha stabilizer, etc. Optimization results were compared with those from commercial plant of which capacity is 150,000 BPSD. From this comparison, we can save 20,000,000 Kcal/h in the optimal case. It is also concluded that annual capital and operating cost was reduced from 10,649,000 US$/ to 9,185,230 US$/y, which is equivalent to 14% cost saving.
