In the pool type Fast Breeder Reactors the roof structure is penetrated by a number of pumps and heat exchangers which are cylindrical in shape. Argon gas in reactor is sandwiched between the free surface of sodium and the roof structure and can flow in the annular space between the ... En savoir plus

Metal hydride based thermal energy storage systems belong to the category of heat storage systems which rely on reversible thermo-chemical reactions to store and release heat. Specifically, these systems utilize metal/alloy hydride decomposition (endothermic) and formation (exothermic) ... En savoir plus

This study allows to establish the possibility to carry out the pyrolysis of mixtures of ethane-propane in an existing steam-cracking reactor (SCR) originally designed for ethane pyrolysis. The final goal of this study was to minimize new investments, e.g. a purchase of new equipment, ... En savoir plus

Oxygen delignification is a technology established worldwide and a common operation in pulp mills that use Kraft cooking. The reasons for using this technology are the reduction of organochlorine compounds in the effluents, and economy of chemicals in the bleaching stage. The objective ... En savoir plus

Intermediate heat exchanger (IHX) in a pool-type liquid metal cooled fast breeder reactor is an important heat exchanging component as it transfer heat from the radioactive primary sodium in the pool to the non-radioactive secondary sodium. The secondary sodium ultimately heats up water ... En savoir plus

Sustainable wastewater management has stimulated the exploration of innovative technologies, such as electrochemical nutrient recovery, which promises efficient recovery and reuse of vital nutrients, reducing environmental impacts and resource wastage. This study presents the modeling of ... En savoir plus

A general purpose stainless steel micro reactor setup for methane conversion is being designed for research purposes. We intend to design and build a modular device that would be able to manage different types of reactions depending on the installed modules. The device should be able to ... En savoir plus

Gas to liquid (GTL) technology can convert methane from the natural gas to liquid fuels and other valuable hydrocarbons which can then be quickly and efficiently transported. The catalytic Fischer-Tropsch (FT) synthesis is the most critical step of the GTL process, as it is in this step ... En savoir plus

A defining characteristic of atomic layer deposition (ALD) is the sequential exposure of a surface to self-limiting, saturating reactions. Temporal ALD operates through intermittent purge cycles, while spatial ALD relies on physical separation accomplished by delivering reactants through ... En savoir plus

The AC losses that superconducting magnet systems experience during transient events are an important design consideration in fusion reactors. We present results on the approach for calculating AC losses in the high temperature superconducting (HTS) toroidal field (TF) magnets of the ... En savoir plus
