BACKGROUND Community concern about asthma prompted an epidemiological study of children living near a petrochemical refinery in Cape Town, South Africa. Because of resource constraints and the complexity of refinery emissions, neither direct environmental measurements nor modelling of airborne pollutants was possible. Instead a meteorologically derived exposure metric was calculated with the re...
The present work examined data obtained during the analysis of Hearing Reduction (HR) of Abadan Petroleum Refinery (Abadan PR) workers of Iran with a history of disease and injuries. To this end, all workers in the refinery were chosen. In this research, the effects of history of disease and injury including trauma, electric shock, meningitis-typhoid disease and genetic illness as well as conta...

Crude oil distillation (atmospheric distillation column with furnace) consumes about 50% of the energy required in oil refinery plant. To achieve further reduction of the energy required in oil refinery plants, it is required to investigate the crude oil distillation and to retrofit it for energy saving process. Recently, authors developed an innovative process design technology, self-heat recu...
background heat, chemical and organic pollution are three types of environmental pollution, caused by refinery and petrochemical industries. problems caused by hear and chemical pollutants are currently resolved to some extent but organic pollution such as poly aromatic hydrocarbons (pahs) are still considered as important problems of industry and environment. objectives a laboratory study was ...
This paper discusses different aspects of the optimization of the distribution of hydrogen in a petrol refinery through a network that connects production and consumption plants. Due to the lack of reliable information from the field measurements, a previous stage of data reconciliation is required. The hydrogen distribution problem can be formulated as a non-convex NLP one, which implies the p...
In the paper the problem of estimating the octane number of powerformed gasoline produced in a refinery is addressed. The model is designed in order to replace the existing measurement device during maintenance operation guaranteeing the continuity of product quality monitoring and control. Linear and nonlinear Moving Average models based on MLP neural networks have been designed to take into a...
Existing refinery distillation systems are highly energy-intensive, and have complex column configurations that interact strongly with the associated heat exchanger network. An optimisation approach is developed for existing refinery distillation processes. The optimisation framework includes shortcut models developed for the simulation of the existing distillation column, and a retrofit shortc...
