Process Resilience Analysis Framework for Design and Operations
(2018-11-27)
Process plants are complex socio-technical systems that degrade gradually and change with advancing technology. This research deals with exploring and answering questions related to the uncertainties involved in the process ...
Application of Computational Fluid Dynamics (CFD) to Study Liquefied Natural Gas (LNG) Pool Fires
(2016-12-07)
Liquefied Natural Gas (LNG) pool fires pose a major risk to LNG facilities. The radiant energy from a LNG pool fire can be sufficiently high to threaten the structural integrity of the facility, plant personnel, fire ...
Chemical Kinetics of Organophosphorus Fire Suppressants
(2018-06-18)
Organophosphorus compounds (OPCs) have significant fire suppression capabilities but are not well understood. Chemical kinetics mechanisms can provide invaluable information about how OPCs suppress flames; however, the ...
Investigation of a Cost-Effective Method of Nitrogen Inerting of Multicomponent Hydrocarbon Gas Mixtures in Large Storage Tanks
(2018-08-01)
The heavy dependence of the world on oil and gas for daily activities has made it highly vital that we do not lose them to incidents such as fires, spills, etc. In addition to economic losses, these incidents also result ...
Efficient Nonlinear Optimization with Rigorous Models for Large Scale Industrial Chemical Processes
(2011-08-08)
Large scale nonlinear programming (NLP) has proven to be an effective framework
for obtaining profit gains through optimal process design and operations in
chemical engineering. While the classical SQP and Interior Point ...
Decontamination Foam for Chemical Spill Mitigation
(2016-05-27)
The release of hazardous chemicals poses a threat to individuals in the area of a release and to responders who attempt to limit the damage of the release. For a liquid phase spill, the most common decontamination technology ...
Probabilistic Risk Assessment Tool Applied in Facility Layout Optimization
(2016-06-01)
The severity of several chemical incidents occurred in the recent past has been attributed to improper layout arrangement or proximity of a chemical facility to a densely populated area although this is not a new problem. ...
Safety and Techno-Economic Analysis of Shale Gas to Butadiene Process
(2017-12-07)
The recent discoveries of substantial reserves of shale gas have significantly impacted butadiene production and prices. Shale gas offers a competitive feedstock that can be used to produce a variety of chemicals and ...
Hybrid Flammable Dust-Gas Cloud Ignition Using a Modified Standard Minimum Ignition Energy Device
(2017-12-12)
Hybrid dust-gas explosion is a persistent problem in process industries because of its ease of ignition as well as serious consequences. Ease of ignition is quantified by minimum ignition energy (MIE), which is associated ...
A Computational Fluid Dynamic Evaluation of Unconfined Hydrogen Explosions in High Pressure Applications
(2017-12-06)
Over the last few decades, the demand for hydrogen has significantly grown. Its high energy content and relatively small environmental effect make it an ideal energy source and chemical feedstock. However, the perceived ...
