Abstract
본 발명은 이중 칼럼 극저온 공기 분리 사스템을 이용하여, 연소 터빈 압축기로부터의 압축 공기의일부분을 냉각하여 정제하고, 그 결과 생성된 냉각 공기의 제1부분을 일 팽창시키고, 그 팽창 공기를 저압 칼럼으로 유입함으로써 통합되는 고압 연소 터빈에 관한 것이다. 그 결과로서 생성된 냉각 공기는 재냉각되고, 유량 억제되어 고압 칼럼으로 유입된다. 질소 생성물 흐름은 터빈 연소기로 복귀되고, 이 질소 생성물 흐름의 일부분은 선택적으로 냉각되고, 유량 억제되어, 고압 칼럼으로 재순환된다. 바람직하게는 ,고압 칼럼이 연소 터빈 공기 압축기로부터의 압축 공기의 절대 압력이 약 20% 내지 약 85%의 범위에 있는 절대 압력에서 작동한다. 선택적으로, 고농도 산소 액체 또는 고농도 질소 액체는 질소 생성물의 수용가 적은 기간 중에는 고압 칼럼으로 부터 배출되어 저장되고, 질소 생성물의 수용가 많은 기간 중에는 저압 칼럼으로 추가 공급하기 위해 저장소로 부터 배출된다. 이와는 다르게, 고순도 액체 산소가 산소 생성물의 수요가 적은 기간 중에는 저압 칼럼으로 부터 배출되어 저장되고, 산소 생성물의 수요가 많은 기간 중에는 저장소로부터 배출되어 , 고압 칼럼으로부터 배출된 산소 생성물을 보충한다.
