Oil pipeline Supervisory Control and Data Acquisition (SCADA) systems monitor and help control pipes transporting both crude and refined petroleum products. Typical SCADA system architectures focus on centralized data collection and control – however, this system has vulnerabilities that decrease the overall security of the system, especially for an oil pipeline SCADA. Service-oriented architec...

The majority of overland transport needs for crude petroleum and refined products are met using pipelines. Numerous studies have developed optimization methods design these systems in order to minimize construction costs while meeting capacity requirements. Here, we formulate problems optimize the operations existing single liquid commodity pipeline subject physical flow pump engineering constr...

لوله های مدفون شده بطور گسترده ای در انتقال نفت و گاز بکار برده می شوند. در این میان عوامل گوناگونی تظیر عیوب و خوردگی داخلی و خارجی می تواند منجر به نشتی و شکست لوله و متعاقبا صرف هزینه های جانی و مالی گزافی گردد. در این پروژه با تحلیل اجزای محدود ترک در لوله های مدفون شده. ضرایب شدت تنش برای ترک های واقع در جداره داخلی و خارجی لوله های مدفون شده بدست آمد. بار اعمالی بر لوله از طرف خاک با اس...

A prototype least cost pipeline routing was performed using various data and GIS analysis. Ahvaz-Marun oil pipeline in south west of IRAN was chosen for development of the prototype. The Ahvaz-Marun pipeline was about 34-km and carries Ethan gas from Marun Petrochemical Company (MPC) to Ahvaz. A model was developed incorporating pipeline length, topography, geology, land use, stream, wetland, r...

The leakage of petroleum can lead to serious economical loss. How to find out leakage spot is the key technology that we will discuss in the paper. In this paper, we apply wavelet transform to solving the problem. Because the audio signal from the leakage spot is very weak, when the sound spreads to the ends, the signal tested by sensor has been sinked down by other noise signals. It is difficu...

Workers in the petroleum industry are potentially exposed to a variety of petrochemicals, including benzene or benzene-containing liquids. Although a large number of studies of petroleum workers have been conducted to examine leukemia and other cancer risks, few existing studies have investigated cell-type-specific leukemias. One of the major reasons for the lack of cell-type-specific analysis ...
