IIR document
Parameter optimization of successive stages of the technology for obtaining 3He isotope from natural helium.
Number: pap. n. 720
Author(s) : BONDARENKO V. L., GRAFOV A. P., KUPRIYANOV M. Y.
Summary
The problem of 3He shortage can be solved by cryogenics by means of commodity helium, which is a natural mixture of 4He-3He isotopes. The structural scheme of a laboratory unit with description of the work process and parameters is given. An industrial technology, consisting of three stages: filtration, rectification and sorbtion, is written about. The enrichment ratio selection method, according to adjacent technological stages of 3He production from the commodity helium, on an assumption of ensuring minimum specific energy costs for thermostating, is given.
