Abstract
Method and Apparatus for separating at least one CO isotope compound, especially isotope compound 13C16O, from natural CO, comprising: a rectification column system (110) comprising a plurality of rectification sections (112,114,116,118,120) arranged adjacent to one another in a chain-like manner, including an upper rectification section (112) and a plurality of lower rectification sections (114,116,118,120), each rectification section comprising a heating means (112a,114a,116a,118a,120a) to maintain evaporation of liquid present therein, provided that the heating means (112a) of the at least one of the plurality of rectification sections (112) is provided to comprise a heat pump cycle (112b).
Claims20
A method for separating at least one CO isotope compound from natural CO, comprising:
- subjecting a CO feed stream to rectification in a rectification column system (110) comprising a plurality of rectification sections (112,114,116,118,120) arranged adjacent to one another, including an upper rectification section and a plurality of lower rectification sections, wherein, during operation of the rectification column system, evaporation of liquid present in the rectification column is achieved by heating liquid in each rectification section by heating means provided in each rectification section,
- wherein heating of at least one of the plurality of rectification sections is provided by heating means comprising a heat pump cycle (112b), and heating of at least one further rectification section of the plurality of rectification sections is provided by means comprising an electrical heater.
An apparatus for separating at least one CO isotope compound from natural CO, comprising:
- a rectification column system (110) comprising a plurality of rectification sections (112,114,116,118,120) arranged adjacent to one another, including an upper rectification section (112) and a plurality of lower rectification sections (114,116,118,120), each rectification section comprising a heating means (112a,114a,116a,118a,120a) to maintain evaporation of liquid present therein,
- wherein the heating means (112a) of at least one of the plurality of rectification sections (112) comprises an external heat pump cycle (112b), and the heating means of at least one further rectification section of the plurality of rectification sections comprises an electrical heater.
