Investigating Microbiologically Influenced Corrosion Using Co-culture Biofilms
(2018-11-19)
A holistic understanding of microbiologically influenced corrosion (MIC) requires investigation of the underlying microbiological, metallurgical and electrochemical mechanisms. MIC studies are typically conducted using ...
Cumulative Risk Assessment to Analyze Increased Risk Due to Impaired Barriers in Offshore Facilities
(2019-04-09)
Investigation of past incidents always reveal deficiencies that are not directly equipment-related, but may be non-technical in nature, such as procedural deviation, inadequate communication etc. Past risk assessment models ...
Safer and More Efficient Reactor Design and Operation for N-Oxidation of Alkylpyridines – From a Perspective of Reactor Modeling and System Analysis
(2017-10-09)
This work aims to promote continuous manufacturing of fine chemicals and pharmaceuticals by proper reactor design and operation. These synthetically important yet potentially hazardous chemistries are conventionally carried ...
Effect of Dust Dispersion and Morphology on Dust Deflagration Hazard
(2019-04-05)
Dust explosions have led to numerous fatalities, injuries and property loss. Standards (ASTM, ISO etc.) mention a 20 L or a 1 m^3 apparatus to measure explosion parameters. These standards assume the dust particle size ...
Probabilistic Risk Assessment of Offshore Production Platform by Bayesian Network Application to HAZOP and Bow-tie Studies
(2016-12-02)
Successful risk management in an offshore oil and gas production platform requires accurate and up-to-date probability of occurrence of process safety events. Traditional hazard identification and risk assessment techniques ...
Application of Fuzzy Logic to Quantify the Uncertainty in Layer of Protection Analysis
(2017-01-23)
Layer of Protection Analysis (LOPA) is a widely used semi-quantitative risk assessment method. LOPA includes both frequency and consequence expressed in an order of magnitude approximation. Compared with Quantitative Risk ...
Multi-Objective Analysis of a Gas-to-Liquid (GTL) Process from Economic, Safety, and Environmental Perspectives
(2017-07-25)
One of the most important challenges facing chemical engineers today is developing more efficient processes that reduce the discharge of greenhouse gasses (GHG) and the usage of material and energy resources. Furthermore, ...
Improving Workplace Safety by Thinking About What Might Have Been: To What Extent, Why, and When Does Counterfactual Thinking Influence Workplace Safety Behavior?
(2017-06-29)
Human information processing theories of workplace safety suggest that cognition is an antecedent of safety behavior. However, little research has directly tested cognitive variables as predictors of workplace safety within ...
Thermal Hazard Analysis of Nitroaromatic Compounds
(2019-07-18)
Nitroaromatic compounds are among the largest group of industry chemicals. Due to the high bond-association energy (BDE) of the C-NO2 in nitroaromatic compounds (297 ± 17 kJ/mole), once the runaway reaction is triggered, ...
Process Hazard Evaluation and Safer Design for Oxidation of Secondary Alcohols to Ketones Using Hydrogen Peroxide
(2019-11-08)
Ketones are industrially produced in large quantities. They find application as solvents and polymer and pharmaceuticals precursors. Substantial efforts have been put towards a green oxidation of alcohols to ketones with ...
