Inventory control of spare parts is essential to many organizations, since excess inventory leads to high holding costs and stock outs can have a great impact on operations performance. This paper proposes a methodology for effective spare parts inventory control, motivated by a case study at a large oil refinery. Different demand modeling techniques and inventory policies are evaluated using r...

This paper identifies and discusses critical factors that are important in effectively implementing risk-based decision making for corrective action. In addition, approaches are presented to address these factors. A corrective action project at an oil refinery is used to illustrate the ideas presented.

INTRODUCTION This study assessed the air exhaustion control of corrugated plate interceptor (CPI) oil separators in a refinery wastewater treatment plant for biodegradation of volatile organic compounds (VOCs) by deep activated sludge aeration systems. Three approaches were used to derive VOC emission factors: * (a) Calculating using the aeration rate and VOC gas-liquid equilibrium concentratio...

A chemical engineering approach for the rigorous construction, solution, and optimization of detailed kinetic models for biological processes is described. This modeling capability addresses the required technical components of detailed kinetic modeling, namely, the modeling of reactant structure and composition, the building of the reaction network, the organization of model parameters, the so...

In this present study the dissolved air flotation (DAF) system was investigated for the treatment of Kermanshah Oil Refinery wastewater. The effect of three parameters on flotation efficiency including of flow rate (outflow from the flotation tank), saturation pressure and coagulant dosage on chemical oxygen demand (COD) removal was examined experimentally. All the experiments were done under a...

Submit Manuscript | http://medcraveonline.com J Microbiol Exp 2015, 2(3): 00048 are the main oil constituent release by industrial and domestic sources, accumulation of dispensed oil and oil derivatives released, separated in oil Refinery and from storage tanks create huge environmental hazard [1-4]. Therefore controlled and monitoring system was adapted to prevent the release of hydrocarbon in...

The main objective of this study is to identify the inherent benefits associated with integrating a new petrochemical facility existing refinery. Petrochemical complexes heavily rely on feedstocks like naphtha and refinery gases, which are frequently produced in oil refineries, ensuring reliable supply essential raw materials. Integration between becomes necessary due their downstream position ...

Naphthenic acids and TAN are one of the ever-increasing crucial problems in oil, shale oil and sand oil industry and also environment protection. Furtherer, they increases the corrosion of some parts of a refinery and transport pipelines and also can create nanoemulsions and make complicated the refining process especially in desalters. To prevent these problems it is important to first obtain ...

The incidence of myelodysplastic syndrome (MDS) experienced by cohorts of 16,467 petroleum distribution workers and 28,554 oil refinery workers has been investigated. Study subjects were all those male employees first employed at one of 476 UK petroleum distribution centres or eight UK oil refineries in the period 1946-1974; all subjects had a minimum of twelve months employment with some emplo...
