A Guideline for the Dynamic Barrier Management Framework Based on System Thinking
(Journal article; Peer reviewed, 2019)Accident investigations in process industry indicate that inadequate barrier management has been one of the main causes of many major accidents. Barriers degrade over time and at different rates, and these degradations may ... -
An evaluation of effects of fuel parameters and flue gas recirculation on NOx emissions through detailed chemical kinetics simulations
(Journal article; Peer reviewed, 2019)In this work the effects of fuel parameters and under grate flue gas recirculation (FGR) are investigated when applying staged air combustion of solid fuel for the purpose of NOx reduction. In addition to temperatures, ... -
An Integrated Approach to Support the Dynamic Risk Assessment of Complex Industrial Accidents
(Journal article; Peer reviewed, 2019)Recent major accidents in the offshore oil and gas (O&G) industry have showed inadequate assessment of system risk and demonstrated the need to improve risk analysis. While direct causes often differ, the failure to update ... -
An Approach to Update the Failure Rates of Safety Barriers Based on Operating Experience
(Peer reviewed; Journal article, 2022)Hazardous events in process plants like the leakage of dangerous substances can result in severe damage, and such an event is often defined as the TOP event of a fault tree analysis (FTA) in a quantitative risk analysis. ... -
Assessment of Transient NOx Reduction Potential in Wood Stoves
(Journal article; Peer reviewed, 2020)NOx emissions from wood stoves remain a significant concern, even though modern wood stoves are continuously improved regarding emissions due to incomplete combustion, e.g. particulates of organic origin. Today, state of ... -
Business intelligence for the analysis of industrial accidents based on MHIDAS database
(Peer reviewed; Journal article, 2021)Reducing the frequency and severity of accidents in industrial processes is a continuous open challenge. Learning from previous events represents a crucial instrument to ensure an improved design of industrial plants, ... -
Carbonization pressure influence on fixed carbon yield
(Journal article; Peer reviewed, 2018)Biocarbon, or charcoal, is receiving increased attention as an increasingly important reductant in metallurgical industries, and has as well many others uses, e.g. as high quality fuel or as activated carbon. Traditional ... -
CO2 reactivity assessment of woody biomass biocarbons for metallurgical purposes
(Journal article; Peer reviewed, 2016)Replacing the use of fossil reductants with biocarbons in metallurgical industries has a great potential with respect to reducing CO2 emissions and the contribution from this industry to the increasing greenhouse gas effect. ... -
Coal Based Power Plants Using Oxy-Combustion for CO2 Capture: Pressurized Coal Combustion to Reduce Capture Penalty
(Journal article; Peer reviewed, 2012)The goal of this paper is to design and study a new variation of an oxy-combustion coal based power plant with CO2 capture that employs a pressurized coal combustor. The concept is compared with an atmospheric pressure ... -
Comparison of risk-based maintenance approaches applied to a natural gas regulating and metering station
(Peer reviewed; Journal article, 2020)In the last decades, many researchers have directed their efforts towards the safety improvement of plants where hazardous substances are processed or handled. This attitude has led to developing strategic plans for ... -
