Parametric Analysis and Optimization of Nuclear Assisted Electrolytic Hydrogen Production System for On-site Applications

By Rupsha Bhattacharyya, Sachin Kamath

Abstract: The use of compact water electrolyser units as an alternative source of hydrogen to the high pressure hydrogen cylinder banks used at present in nuclear and thermal power reactors for turbo-generator rotor cooling applications has been analysed in this work. Financial metrics have been used for assessment of the technology substitution in the nuclear industry in India, primarily by comparing the levelised costs of onsite hydrogen generation in small generators …

Suitability of Methyldiethanolamine (MDEA) and Piperazine (PZ) for Improving CO2 Absorption Efficiency Using Rotating Packed Bed (RPB) Technology: A Modeling and Simulation Study

By Isaac Jato, Umar Farouk Aliyu, Atuman Samaila Joel, Olumide Olu Olubajo

Abstract: Carbon dioxide (CO2) capture and storage (CCS) is an essential technology for reducing atmospheric CO2 emissions and mitigating climate change, especially in fossil-fuel power generation. However, the high cost of CCS technologies has hindered their widespread adoption. In this study, we modeled CO2 removal using a rotating packed bed (RPB) technology using Visual Fortran and Aspen Plus software. We made use of a blended amine solution including different molar concentration …
