This study examined the impact of Human Resource (HR) practices (selection, training, compensation, and appraisal) and participation on the financial performance of U.S. petrochemical refineries. Survey results from HR and Operations respondents indicated that appraisal and training were significantly related to workforce skills and that training and compensation were marginally related to work...

We present a methodology for automatic corrosion detection in digital images of carbon steel storage tanks and pipelines from a petroleum refinery. The database consists of optical digital images taken from equipments exposed to marine atmosphere during their operational life. This new approach focuses on color and texture descriptors to accomplish corroded and noncorroded surface area discrimi...

We present the prototype omVR, which is a Virtual Reality based safety training system in a petroleum refinery. It provides an advanced technique for personnel safety training and allows users to navigate through the training setup and interact with parts of the refinery. By using a head mounted display a high degree of immersion is achieved. omVR is the implementation of a training scenario, w...

The current study evaluates the performance of a pilot scale fed batch reactor (FBR), fo llowed by coagulation and sand filtration, for the treatment of an oil refinery wastewater. The total reductions in COD, BOD, oil contents and phenol were 95.11%, 94.30%, 99.47% and 100%, respectively, with FBR followed by coagulation and sand filtration. This FBR-coagulation-sand filtration treatment syste...

Due to the benefits reported on the use of continuous centrifugals in refineries elsewhere in the world, it was decided by Tongaat-Hulett Sugar Ltd to evaluate the Schultz, Tait and Greig (STG) continuous centrifugal at their sugar refinery in Durban, South Africa. This paper deals with the installation, commissioning and evaluation of the continuous centrifugal. Results of tests done on first ...

Traditional optimization of production system and utility system is carried out separately which cannot ensure that the entire refinery system is optimized globally. In this paper, a novel integrated approach is proposed to optimize process production planning and utility system operation simultaneously. A refinery-wide mixed integer nonlinear programming model is proposed and the traditional m...

background and objective: prevention of accidents—a crucial requirement in oil industries—involves hazard recognition, risk assessment, and corrective actions. the purpose of this study was to compare the etba and hazop techniques for risk assessment in a gasoline refinery unit. methods: in this case study, data were collected using process flow diagram, walking–talking through method, piping a...

Unpublished AIChE shall not be responsible for statements or opinions contained in papers or printed in its publications ABSTRACT The refinery business involves tasks spanning across several departments and using large amounts of data. These processes include crude procurement, logistics scheduling, storage (tank) scheduling and crude scheduling. Integrated decisions based on the entire supply ...

The effects of the energy crisis and rising demand have sparked development to improve efficiency in using fuel oil. According Indonesia's oil resources, increasing refinery capacity building mini refineries is essential secure local production. It more effective cost-effective construct a small with configuration starting flash unit or pre-fractionator, an atmospheric distillation unit, vacuum...
