연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

An adsorptive separation process is set forth for recovery of two gas products in high recovery and high purity using adsorption, depressurization low pressure purge, evacuation and repressurization. Depressurization and purge effluents are recycled to feed and optionally pressure equalizations are performed after the adsorption and after the evacuation as well as a pressure equalization using the low pressure effluent.

A pressure swing adsorption process for recovery of two gas products at high recovery and high purity from a feed gas stream containing said products wherein a first gas product is a less strongly adsorbed component and a second gas product is a more strongly adsorbed component, comprising: (a) introducing a feed gas stream at elevated pressure containing said less strongly adsorbed component and said more strongly adsorbed component into one of a plurality of parallel adsorptive beds filled with an adsorbent selective for said more strongly adsorbed com...
