This work investigates the use of a specially designed cylindrical metal cell, in order to obtain complex permittivity and tanδ data of highly insulating High Voltage (HV) transformer oil samples. The data are obtained at a wide range of frequencies and operation temperatures to demonstrate the polarization phenomena and the thermally stimulated effects. Such complex permittivity measurements m...

Studies of the energy return on investment (EROI) for oil production generally rely on aggregated statistics for large regions or countries. In order to better understand the drivers of the energy productivity of oil production, we use a novel approach that applies a detailed field-level engineering model of oil and gas production to estimate energy requirements of drilling, producing, processi...

This paper describes the simulation setup applied in an introductory study in connection with implementation of subsea processing equipment at an already operating gas and oil field. The primary aim of the subsea processing equipment is to increase the oil recovery, but it is also considered as an important technological step forward. A subsea separation and boosting station is planned installe...

We have applied the SIPE system (a classical planning tool, see [1] ) to the Coast Guard’s problem of oil spill response. The Coast Guard has final responsibility for cleanup actions when an oil spill occurs in coastal waters. Oil spill actions fall into two types, "deploying" clean up equipment from the site near the coast where it is stored, and once deployment is complete, "employing" the eq...

The oil industry needs solid and reliable materials in almost all processes. By making nano-scale materials, lighter, more robust, and more robust equipment than today's products can be produced. Nanotechnology in the field of oil industry and its related industries, in addition to reducing the environmental hazards of this sector and the possibility of saving from harvesting of underground res...

Vegetable oil is one of the basic food items which is consumed by almost every human being in this universe. Therefore quality of vegetable oil should be good enough so that it accounts for healthy life. In vegetable oil manufacturing there are four major steps involved which are neutralization, degumming, bleaching and deodorization. Among these steps bleaching is the very important and critic...

This paper presents an operational synthesis of major oil spill response methods (mechanical, chemical, etc.) and the corresponding oil response equipment for sea context (booms, skimmers, etc.). We focus on important features of oil spill response, in order to formulate a decision-based database, capable of supporting the development of a complete oil spill response operation. Moreover, we cla...

Condition Monitoring of rotating equipment has been a very important aspect in the field of maintenance engineering. There are various types of condition monitoring techniques, namely: Vibration Analysis, Oil Debris Analysis, Ferrography, Temperature analysis. Among all these techniques, vibration analysis have gained much importance in the field of condition monitoring because of its accuracy ...
