Analytic information technologies in oil refinery
Problems of constructing analytical information systems and their application in controlling industrial processes at oil refining enterprise are considered. Systems being focused on control decisions support problem are regarded. Basic tasks, arising at constructing such systems and the ways to overcome them are listed. The appearance of multipurpose analytical information system (MAIS) is deve...
متن کامل[Liver enzyme abnormalities among oil refinery workers].
OBJECTIVE Occupational exposure typical of an oil refinery may alter liver function among the workers. Thus, the objective of the study was to identify risk factors for liver enzyme abnormalities among oil refinery workers. METHODS The workers at an oil refinery in Northeastern Brazil underwent routine annual medical examination from 1982 to 1998. This case-control study investigated all the ...
متن کاملOptimal Scheduling of Refinery Crude-Oil Operations
This thesis deals with the development of mathematical models and algorithms for optimizing refinery crude-oil operations schedules. The problem can be posed as a mixed-integer nonlinear program (MINLP), thus combining two major challenges of operations research: combinatorial search and global optimization. First, we propose a unified modeling approach for scheduling problems that aims at brid...
متن کامل[Occupational accidents in an oil refinery in Brazil].
OBJECTIVE Work in oil refineries involves the risk of minor to major accidents. National data show the impact of accidents on this industry. A study was carried out to describe accident profile and evaluate the adequacy of accident reporting system. METHODS Data on all accidents reported in an oil refinery in the state of Rio de Janeiro for the year 1997 were organized and analyzed. The study...
متن کاملWireless Critical Process Control in Oil and Gas Refinery Plants
Wireless telemetry systems are now becoming a relevant topic in the field of critical process control in industrial plants and oil/gas refineries. In contrast to wire line communication, wireless links are inherently unreliable. This unreliability depends critically on the propagation environment of the radio-links as the layout of scattering objects (pipes and metallic structures) influences t...
