Comparison of Technologies for CO2 Capture from Cement Production — Part 2: Cost Analysis
(Journal article; Peer reviewed, 2019)This paper presents an assessment of the cost performance of CO2 capture technologies when retrofitted to a cement plant: MEA-based absorption, oxyfuel, chilled ammonia-based absorption (Chilled Ammonia Process), ... -
Reliability framework for power network assessment
(Journal article; Peer reviewed, 2019)Reliability of power system in terms of investments in network maintenance and restructuring for power distribution network has gained importance due to increase in distributed generation. To determine the reliability of ... -
Multi-Ejector Concept: A Comprehensive Review on its Latest Technological Developments
(Journal article; Peer reviewed, 2019)The adoption of the EU F-Gas Regulation 517/2014 and the resulting development of the multi-ejector concept have led carbon dioxide to take center stage as the sole refrigerant (R744) in several applications. Therefore, a ... -
Cavities in Mass-Impregnated HVDC Subsea Cables Studied by AC Partial Discharge Measurements
(Journal article; Peer reviewed, 2019)Partial discharge measurements have been used for studying shrinkage voids in the insulation of mass-impregnated high voltage DC subsea power cables. Three 4.5-m long cable samples were subjected to ac partial discharge ... -
