Opis:
Results of an extensive research program, aimed at finding new, more efficient activators of carbon dioxide absorption into aqueous carbonate/bicarbonate solutions are presented. Both single amines (2-ethyl-aminoethanol, 2-isopropyl aminoethanol, piperazine, tetraethylenepentamine, N-ethyl-piperazine and glicyne) and amine mixtures have been investigated. Absorption rate measurements were conducted in a laminar-jet absorber. Reaction rate constants for the particular activators were determined. Mixtures of aliphatic amines with cyclic amines, as well as mixtures of cyclic amines with cyclic amines were found to exhibit synergetic effect. Such amine mixtures might be used as new promoters for CO2 absorption in carbonate solutions in the modified Benfield process.

Opis:
Important issue in the perspective of nuclear energy development in the near future is the partitioning and transmutation (P&T) of spent nuclear fuel. For years the European Commission (EC) has sponsored this scientific activity through the Framework Programmes (FP). One of the milestones for P&T is the development of accelerator driven systems (ADS). Extensive research in this field was carried out within the EUROTRANS project of 6th FP of EURATOM. Part of this research was devoted to testing and development of reactivity monitoring techniques in ADS. This paper concerns the methods of the reactivity measurement using the pulsed neutron source (PNS). Due to the fact that basic methods devoted to determine the core reactivity are derived from point kinetics, while real subcritical core kinetics differs from this model, there is a need to improve these methods in order to deal with the observed spatial effects. There are several ways to make these methods work properly and finally it should be possible to achieve this. However, they still need a validation which is supposed to be done within next FP project FREYA.

Opis:
Measurements of the absorption rate of carbon dioxide into aqueous solutions of N-methyldiethanoloamine (MDEA) and 2-ethylaminoethanol (EAE) have been carried out. On this basis a mathematical model of the performance of an absorption column operated with aqueous solution of a blend of the above amines at elevated temperatures and pressures have been proposed. The results of simulations obtained by means of this model are described. The work is a part of a wider program, aimed at the development of a new process.
