Organic Rankine Cycle with Pure and Mixed Working Fluids for LNG Cold Energy Recovery
(Journal article; Peer reviewed, 2019)Liquefied Natural Gas (LNG) contains a large amount of cold exergy, which is normally wasted during the regasification process. Organic Rankine Cycles (ORCs), which have been widely employed for low-temperature waste heat ... -
Oxy-combustion coal based power plants: study of operating pressure, oxygen purity and downstream purification parameters
(Journal article; Peer reviewed, 2014)Oxy-combustion coal based power plants are considered one of the cost effective ways to produce CO2 emission free electricity. Recovery of compression heat and the latent heat from the flue gases can further improve the ... -
Prediction of Condensed Phase Formation during an Accidental Release of Liquid Hydrogen
(Peer reviewed; Journal article, 2022)Hydrogen can be adopted as a clean alternative to hydrocarbons fuels in the marine sector. Liquid hydrogen (LH2) is an efficient solution to transport and store hydrogen onboard of large ships. LH2 will be implemented in ... -
A Risk Aspect of Periodic Testing on Pressure Relief Valves
(Peer reviewed; Journal article, 2022)A pressure relief valve (PSV) is a key safety barrier to prevent the catastrophic rupture of pressure equipment in a process plant. The safety function of a PSV is to open and relieve the pressure when the equipment pressure ... -
‘Safety Hunting’: a Serious Gaming Approach for Industrial Safety Training
(Peer reviewed; Journal article, 2023)Current operational safety training methods for the chemical process industry typically focus on acquiring and evaluating knowledge and technical know-how about safety measures and procedures. Although these are valuable ... -
Subsea Oil Spill Risk Management Based on Sensor Networks
(Peer reviewed; Journal article, 2020)The use of Wireless Sensor Networks (WSNs) in support of Dynamic Risk Assessment regarding oil spills still lacks a proper integration. WSNs enable prompt responses to such emergencies through an appropriate inspection, ... -
Synthesis of Heat-Integrated Water Networks with exergo-economic criteria
(Peer reviewed; Journal article, 2023)This paper considers the exergy analysis of Heat-Integrated Water Networks (HIWNs) rarely addressed in the literature. Two objective functions were analyzed, with the first minimizing the total annualized cost (TAC) and ... -
Techno-economic Analysis of Different Liquid Air Energy Storage Configurations
(Journal article; Peer reviewed, 2022)With the increasing use of renewables in energy systems, grid stability becomes a major issue due to the intermittent nature of energy sources such as solar and wind. To compensate for the unstable renewable energy sources, ... -
Techno-Economic and Environmental Assessments of Thermochemical Routes Integrated into the Brazilian Sugarcane Industry for the Production of Renewable Jet Fuel
