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...

The energy demand in our modern society is continuously rising, which clearly shows that fossil fuels will for many decades still play an important role – oil and natural gas are important energy resources in this picture. Nevertheless, oil and natural gas reserves are limited, and it is therefore a prioritized task to produce more oil and gas from existing wells and reservoirs for better explo...

−− This work presents a stochastic multiperiod model for representing a petroleum refinery. Uncertainty is taken into account in parameters such as demands, product sale prices and crude oil prices. In the present work, uncertainty is considered as a set of discrete scenarios, each representing a possible shifting of market expectations. Every environment is weighted through an expected probabi...

The prime aim of the current work was to illustrate the components existing in repeatedly used cooking oil and to develop an economical process for the production of fatty acids from low cost feedstock waste. The waste cooking oil was characterized by the occurrence of high molecular weight hydrocarbons and polymerized derivative of esters. Triacontanoic acid methyl ester, 2,3,5,8-Tetramethylde...

Water-soluble polymers have been used for a wide variety of applications due to their versatility. Watersoluble polymers are found in many different industries including agriculture, food, plastics, pulp and paper, mining, petroleum, textiles, and waste water treatment. Often, they are used as both processing aids and components of final products. Addition of water-soluble polymers to industria...

The evolution of modern technology for olive oil extraction has affected the industrial sector depending directly on the by-products obtained. The traditional three-phase continuous centrifugation process for olive oil extraction was introduced in the 1970s, notably to increase the processing capacity and extraction yield and to reduce labour. This three-phase manufacturing process of olive oil...

This paper describes the Syrian experience with respect to Naturally Occurring Radioactive Materials (NORM) waste produced by the Syrian oil industry. Three main categories of NORM waste were identified. First, hard scales from decontamination of contaminated equipment and tubular that are considered to contain the highest levels of radium isotopes (Ra, Ra, Ra); this type of waste being current...

The present study examined the biodegradation rate of benzene vapors in a two phase stirred tank bioreactor by a bacterial consortium obtained from wastewater of an oil industry refinery house. Initially, the ability of the microbial consortium for degrading benzene was evaluated before running the bioreactor. The gaseous samples from inlet and outlet of bioreactor were directly injected into a...

In order to conduct safe and efficient flow management of motor or transformer oil, it is necessary to implement specific waste oil analysis and treatment in order to protect the environment and people’s health and safety. The study presents analysis and treatment of waste oil in the electric power distribution companies, showing some data of the MH ''ERS” ZEDP “Elektro-Bijeljina” joint-stock c...

BACKGROUND Occupational and environmental exposure to petroleum refinery products poses a great threat to human health. This study aimed to assess the lung function and Fractional Exhaled Nitric Oxide (FeNO) among petroleum refinery workers. METHODS In this cross-sectional study, 112 participants (56 petroleum refinery workers with mean age 35.20 ± 1.62 years, and 56 age, weight, height, ethn...
