In this article, modeling and optimization of power consumption of two–stage compressed air system has been investigated. To do so, the two – stage compressed air cycle with intercooler of FAJR Petroleum Company was considered. This cycle includes two centrifugal compressors, a shell, and a tube intercooler. For modeling of power consumption, actual compressors isentropic efficiencies and inter...

Equations of state should be tuned to reservoir conditions by PVT tests for phase behavior modeling. This tuning is achievable via an optimization method. In this work, simulated annealing algorithm is applied as a global optimization method to parameter optimization for PC-SAFT from the statistical associating fluid theory incorporating hard chain as reference fluid. The optimization parameter...

abstract petroleum pollution is one of the most common and dangerous pollutions that is due to petroleum industries such as refineries, and consequently of oil pipes and tanks leak causing environmental pollutions. one of the newest born technologies in this area is phytoremediation, in which plants are used for decreasing of petroleum pollution. this technology is used for remediation of soil,...

Effective and careful research has been performed by the Section of Mechanics Teaching and Research, Southwest Petroleum University on the content, status, student characteristics of the non-mechanical and non-civil-engineering engineering mechanics course system. Reform ideas and measures, which are also applicable to other common colleges, have been suggested in the course content and course ...

ABSTRACT Modeling of fluid flow and solute transport through fractured rock is an important component of engineering analysis in many disciplines including groundwater contamination, nuclear waste disposal, petroleum and gas production, mine excavation and geothermal production. Several studies have been conducted on single rock fracture using parallel plate model. An attempt has been made to s...

background: nowadays the eutrophication of water bodies is enhanced due to discharge of effluents and runoffs. therefore, there is a demand for the management of natural and artificial lakes to prevent or postpone this problem. lakes eutrophication is a complex process. therefore computerized models are very important tools to describe this process. although there are several models for this, b...

conclusions the results indicated that the model, compared with other models, was user-friendly and the desired results were obtained by a minimal data. materials and methods the current paper developed a process model. first, a sketch of nitrate and ammonia storage, their specifications and parameters were set out and created on a page, and then, mathematical relations of each process were set...

This paper focuses on ontology construction as a foundation for knowledge representation. We present here the processes of knowledge acquisition, analysis, and representation using a conceptual modeling tool, the Inferential Modeling Technique (IMT), as a basis for ontology construction. To illustrate the knowledge modeling process, we apply IMT for knowledge analysis in the domain of petroleum...
