The upstream petroleum supply chain is inefficient and uneconomical because of the independence of the four complex and fragmented functions which comprise it. Crude oil exploration, trading, transportation, and refining are functions which may be integrated through unified decision-making facilitated by timely information exchange. This exchange has been problematic because the four business u...
The energy industry and in particular the Oil Refineries are extremely important elements in Iraq’s infrastructure. A terrorist attack on one oil refinery will have a catastrophic impact on oil production and the whole economy. It can also cause serious damage to the environment and even losses of human lives. The security of information systems and industrial control systems such as Supervisor...
Nonionic surfactant-stabilised oil-in-water emulsions offer a potentially useful vehicle for transporting heavy crude oils from oilfields to refineries or distribution terminals. Prior to refining, separation of the oil from the emulsion is necessary. Previous studies have suggested that heating the emulsion is sufficient for destabilisation and recovery of the oil. The present work examines th...
Oil refineries provide the lifeblood for global economic health, and disruptions to their operations have major worldwide impact. We are developing a large-scale intelligent refinery control system to assist human operators in controlling refineries during abnormal situations. Based primarily on reactive and procedural approaches to intelligent behavior, the Abnormal Event Guidance and Informat...
During 2010, outbreaks of serogroup C meningococcal (MenC) disease occurred in 2 oil refineries in São Paulo State, Brazil, leading to mass vaccination of employees at 1 refinery with a meningococcal polysaccharide A/C vaccine. A cross-sectional study was conducted to assess the prevalence of meningococci carriage among workers at both refineries and to investigate the effect of vaccination on ...
An Internet based Distributed Control System (DCS) is presented in this paper for monitoring real time data using ordinary web browser. Each DCS will be connected to the central server which will be the system web server. The proposed system is based on the three-tier client-server model. The application server is written in C#.Net. SQL database server 2005 is used for all the DCSs local databa...
Rapid industrialization and urbanization have increased the demand for both energy mobility services across globe, with accompanying increases in greenhouse gas emissions. This short paper analyzes strategic measures abatement of CO 2 emissions from oil refinery operations. A case study involving a large conversion shows that use post-combustion carbon capture storage (CCS) may only be practica...
