Research description
Elaboration of 13C isotope separation technology by cryogenic distillation of carbon monoxide
Introduction
13C isotope separation and production represents a major interest on an international scale. The project aims at researching, designing and implementing an experimental model of a 13C isotope separation technology with the intention of data gathering that would allow for a further development of a productive installation.
Objectives
The main objective of the project is the research, design and implementation of the experimental equipment used for a 13C isotope separation that would lead to experimental data necessary for designing an actual separation technology. More specific, the objectives are as follows:
- Research, design and implementation of the installation and the elaboration of a production method and an advanced purifying technology of CO for a 500 liters/ 24 hours.
- Research, design and automatization of the experimental installation for cryogenic separation of 13C isotope.
- Elaboration of the separation technology by cryogenic distillation of CO and data gathering for a further production facility of a 1000 grams 13C/ year capacity.
- Dissemination of the results.
Methodology
Each objective in the project would be attained by an intensive study of the chemical and physical properties of 13C isotope and of the separation process followed by mathematical calculus and design of the installation. Finally, the experimental model of the separation technology would be tested for data gathering.These data and several separation experiments would create the possibility to implement an actual 13C isotope separation installation to be used for production purposes.
Achievements
The project would lead to results as follows: new information regarding physical and chemical processes involved in the separation of stable isotopes, gas purification, slow process automatization; elaboration of the experimental model of a cryogenic distillation installation; CO production and advanced purification up to concentrations below 1 ppm and for impurities having the freezing point above 82K; full automatization of a complex installation working at 82K and 10-5 tor; elaboration of the 13C separation technology; experimental data gathering; creating the premises for further development and technological transfer.
