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.

A vapor based liquid purification system and process utilizes an evaporator for evaporating a liquid into a vapor and a vapor condenser for condensing the vapor into the processed liquid. The vapor condenser has a stator and a rotor, with the rotor disposed for rotation about the stator. The stator and the rotor each have protrusions proximate to an inlet of the vapor condenser. These protrusions cooperate to draw vapor from the evaporator into the vapor condenser. The stator and the rotor each further have at least one axially extending ridge. These ridges cooperate to move a mixture of the vapor and the processed liquid towards at least one drain in the rotor where the processed liquid is communicated to an outlet of the vapor condenser. A multi-level vapor based purification system may also be utilized. With the multi-level vapor based purification system a vertically oriented conduit provides fluid communication between a vented vessel containing liquid and the evaporator, which is at a height greater than the vented vessel such that the vertically oriented conduit has a length effective to create a low-pressure region within the evaporator.
