Abstract
본 발명은 400 내지 1300nm 파장의 단색광 시그날을 상기 구역(9)의 2개 이상의 지점에서 레이저 원(1), 빔 분할기(2) 및 광학 섬유(3,3a)에 의해 동시에 통과시켜 C8-C10의 방향족 탄화수소 이성질체 혼합물을 분리하는 것에 관한 것이다. 다색 시그날은 상기 지점의 위치에서 센서(4)에 접속된 광학 수신 섬유(5,5a)에 의해 400 내지 3500cm-1의 라만 효과에 상응하게 수용된다. 분광기(6)로 얻은 라만 스펙트럼으로 혼합물의 화학 조성을 측정했다. 분석 절차를 반복하고, 상기 혼합물내에서 이성질체의 농도에 대한 프로파일을 재구성시키고, 처리 및 조절 수단에 의해 분리 공정의 하나 이상의 작동 변수(11,12)로 참조물의 농도 프로파일으 비교한다.The present invention simultaneously transmits a monochromatic light signal having a wavelength of 400 to 1300 nm by simultaneously passing through the laser source 1, the beam splitter 2 and the optical fibers 3, 3a at two or more points in the region 9, and C 8 -C. To separating an aromatic hydrocarbon isomer mixture of 10 . The multicolor signal is received correspondingly to the Raman effect of 400 to 3500 cm -1 by the optical receiving fibers 5, 5a connected to the sensor 4 at the location of this point. The chemical composition of the mixture was measured by Raman spectrum obtained with the spectroscope (6). The analytical procedure is repeated, the profile for the concentration of isomers in the mixture is reconstructed and the concentration profile of the reference compared to one or more operating variables (11, 12) of the separation process by treatment and control means.
