For environmental reasons, the CO2-rich permeate stream from the gas treatment process must be re-injected into the reservoir. The associated gas of an oil-producing field in off-shore Brazil is treated to remove water, hydrocarbon condensate, H2S and CO2.

This document presents the implementation of a cryogenic distillation column in Aspen HYSYS by setting the thermodynamic principles upon which the simulation is founded and verifying isotopic separation models with experimental data available in the literature. The present work proposes the use of a commercial dynamic process simulator such as Aspen HYSYS given its abilities to overcome the challenges described. Dynamic simulation tools are key in the analysis and design of tritium processing systems and the use of commercial simulators can be especially valuable to this end and may add capabilities in terms of standardization of industrial-scale fusion plant modeling and conjunction of operator training systems, human-machine interface and process monitoring and control. The design of the ITER’s Isotope Separation System can still undergo major changes due to its close contact with the Water Detritiation System and this will be decisive in the design of future DEMO detritiation facilities. 169, August, Pages: (online)Ĭryogenic distillation is the best candidate for hydrogen isotopic separation in fusion power plants. The amount of purge gas required depends on the released gas and on the gas purge composition, as well as the size and design of the flare.Įduardo Iraola, José María Nougués, Luis Sedano, Josep Anton Feliu, Lluís BatetĢ021. The most common method for the prevention of air infiltration through the stack exit is to introduce purge gas. Infiltration of air can lead to flame burn back, which in turn could initiate a destruction detonation in the system. The risk associated with this contraction is the depression of the header below atmospheric pressure, allowing outside air to enter into the flare system. The rate of contraction velocity is accelerated if cooling leads to condensation of the contained gas components. During a relief of hot gases, contraction of the gases could occur due to the cool-down to ambient conditions. October, Pages: 81 – 84ĭuring a flare release, the temperature of the flare network has a strong dependence on the relief source and on ambient conditions.
