<글 하단에 Naphtha Isomerazation 프로세싱과 관련하여,
참고로, 본인은 화학공학과 출신은 아닙니다.
궁금한 점입니다.
1. C5/C6 Isomerization Processing의 정확한 목적은 무엇입니까.
(본 프로세싱을 통해 얻는 주 생산물이 Gasoline인데, 화학식은 같고 구조식이 다른 이성질화가 Gasoline을 얻는것과 어떤 연관성이 있는지 모르겠습니다.)
2. C5/C6 Isomerization Processing을 통해 Octane(C8)을 높일 수 있다는 것은, Benzene 제거나 DIH/DIP 등의 Processing과 함께 하기 때문인지요.
혹은, C5/C6 Isomerization Processing 자체만을 통해서도 high Octane이 생성된다는 것입니까.
답변 바라겠습니다.
감사합니다.

Today, UOP remains at the forefront of this technology, offering a broad range of processing options for light naphtha (C5/C6) including upgrading of low octane streams and elimination of benzene.
We offer two Isomerization options to meet your needs. The UOP Penex™ process and the UOP Par-Isom™ process are fixed-bed processes that
improve the octane of C5/C6 streams by isomerizing normal components to branched components using
UOP’s high-activity catalysts. The reaction conditions promote isomerization and minimize hydrocracking.
These processes are capable of saturating Benzene and can be incorporated into a variety of processing schemes to upgrade low octane C5/C6 streams to products with octane ranging from 80 RONC up to 93 RONC. There are three common options:
- Hydrocarbon Once-through – the light naphtha passes through the isomerization reactor only once. Normal paraffins are converted to iso paraffins but the conversion is limited by equilibrium. Typical product octanes are in the 80-84 RONC range.
- Isomerization/DIH – A de-isohexanizer is used to recover and recycle unconverted normal hexane and low octane hexane isomers to the reactor system. RONC values of 87-89 can be achieved.
- DIP/Isomerization/Super DIH – Using a de-isopentanizer upstream of the Isomerization reactor to remove isopentane and a de-ioshexanizer downstream to recover and recycle low octane hexanes, RONC values of 90-93 can be achieved.
