| titleOfInvention | Using heptafluoro-propane as the method for medium centrifugation separation of carbon isotope |
| abstract | A method of using heptafluoro-propane as medium centrifugation separation of carbon isotope, comprising the following steps: purify natural heptafluoro-propane；By purified gaseous state heptafluoro-propane, it is passed through gas centrifuge, each relative molecular mass component in heptafluoro-propane will form different distributions in centrifugal force field, adjust feed flow, adjust essence, lean nozzle pressure, liquid nitrogen cold trap rewinding is used at fine fodder end, lean end respectively simultaneously, and maintains the air for reclaimer system to divide within 2Pa using vacuum pump；After system continuous operation to carbon isotope abundance distribution is stablized, concentration/dilution carbon isotope is obtained.Of the invention using heptafluoro-propane as the method for medium centrifugation separation of carbon isotope, low energy consumption, separation is larger, the large-scale production suitable for cascade form.Separating medium heptafluoro-propane is common extinguishing chemical, and the lean generated after centrifuge separation still can be used as extinguishing chemical normal use, and this method is used for the separation of carbon isotope, has technical feasibility. |
