Title:
A SEPARATION METHOD AND SEPARATION APPARATUS OF ISOTOPES FROM GASEOUS SUBSTANCES
Document Type and Number:
WIPO Patent Application WO2003076053
Kind Code:
A8
Abstract:
A isotopic gas of high purity is obtained at low cast, wherein for example, in a case of separating <13>CH4 from methane gas and obtaining <13>CH4 of high purity, the enrichment of <13>CH4, using the difference in adsorption of <12>CH4 and <13>CH4 onto an adsorbing material, is performed up to a certain concentration, and thereafter, <13>CH4 is enriched by a separation method by distillation that uses the difference in boiling point.
