중잔유의 500 MW급 가스화 복합발전 적용 성능 평가
Performance Evaluation of Heavy Residual Oils in the 500 MW IGCC Plant
초록
원유 정제 잔류물인 중잔유(heavy residual oil)를 발전연료로서 500 MW급 IGCC 플렌트에 적용하였을 때의 성능을 평가하기 위한 방안으로 전적씨스템 모사 방법을 사용하였다. 모사에 적용한 중잔유는 visbreaker residue와 butane asphalt및 국내 정유공장으로부터 입수한 asphalt였으며, 씨스템 모사 방법의 검증을 위해서 중잔유의 가스화반응 모사 결과를 기타 중잔유를 사용하는 IGCC 플랜트에 대하여 같은 모사 방법을 적용하였다. 모사 결과, 중잔유의 가스화 반응은 1,300oC에서 진행하였을 때 가스화 반응에 의해 생성된 생성가스(raw gas)의 발열량은 2,750-2,800 kcal/m3 범위였고, 발전 효율은 43%이상으로 발전 연료로서 적합한 성능을 나타내었다.
As a way to evaluate the performance of the IGCC process with fuels from petroleum refineries, heating values of the raw gas as well as the plant efficiency were simulated by employing the static process simulation technique. Fuels chosen were visbreaker residue, butane asphalt and a asphalt from one Korea Refinery. In order to verify the simulation technique, simulated results of a visbreaker residue were compared first with actual demonstration plant data published from Shell Co. and then the simulation technique was applied to the cases of other fuels, butane asphalt and a Korean refinery asphalt. At the gasifier temperature of 1300℃, simulation results showed that heating value of raw gas produced from residual oils was in the range of 2,750-2,800 kcal/m3 with the plant efficiency over 43%. The results exhibit the technical and economical viability of using heavy residual oils from petroleum refineries as successful fuels in IGCC power plants.
