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 ...
DEVELOPMENT AND APPLICATION OF PROCESS SAFETY INDICES IN EARLY DESIGN PHASE OF CHEMICAL SUPPLY CHAIN
(2018-08-06)
Supply chain network design and optimization are very important in decision making, which gives the ability to stakeholders to assess the massive supply chains to increase profit while minimizing risks. Risks in supply ...
Pipeline Risk Assessment Using Dynamic Bayesian Network (DBN) for Internal Corrosion
(2018-08-03)
Pipelines are the most efficient mode of transportation for various chemicals and are considered as safe, yet pipeline incidents remain occurring. Corrosion is one of the main reasons for incidents especially in subsea ...
Flammability Characteristics of Light Hydrocarbons and Their Mixtures at Elevated Conditions
(2018-11-01)
Accurate data of flammability limits for flammable gases and vapors are needed to prevent fires and explosions. The flammability limit is the maximum or minimum fuel concentration at which a gas mixture is flammable in a ...
Phase Equilibrium Studies on N-Oxidation Systems to Determine Homogeneous Mixture Conditions
(2018-10-24)
The N-oxidation of alkylpyridines is used in the pharmaceutical industries to synthesize alkylpyridine N-oxides that are involved in the production of analgesic and anti-inflammatory drugs. The synthesis process involves ...
Integration of Human Factors in Offshore Blowout Risk Assessment
(2015-11-30)
Human factors (HFs) are important factors to the Macondo well blowout, but traditional risk assessment has not addressed them. Some common methodologies for offshore drilling risk assessment are fault tree, event tree and ...
Data-Based Semi-Automatic Hazard Identification for More Comprehensive Identification of Hazardous Scenarios
(2017-05-30)
As chemical process plants have become more involved and complex, the likelihood of hazardous incidents has increased simultaneously. That is, the more complex a facility’s systems, the more factors engineers must consider. ...
Safety Problems Caused by Hydrate Formation in Deepwater Production Operation
(2017-07-27)
Although hydrate formation phenomenon has been identified for many years, this is still one of the most challenging problems in oil & gas industry as they are associated with flow assurance problems and safety issues. ...
