Biodiesel is a non-petroleum fuel designed to run in a diesel engine. It can be made from a variety of different feedstocks, including virgin vegetable oil, waste cooking oil, and animal fats. The aim of this research was to compare and contrast biodiesel made from fish oil to other more traditional sources. In this paper I examined traditional biodiesel feedstocks available in coastal Alaska. ...

The article discusses the problems associated with metrological support of equipment for geophysical research, issues ensuring uniformity well measurements, creation Russian standards calibrating when determining porosity coefficients and oil, gas, water saturation, parameters defects during cementing technical condition casing strings water-oil-gas flow. creating full-fledged methods measuring...

Oil field assimilation needs a complex of facilities and service lines for oil recovery, transportation and refining. It includes wells, collection stations, pipelines, meters, separators, formation pressure maintenance equipment, roads and power lines. Oilfield assimilation depends on the geographical and climatic features of the field, such as the areas under existing buildings, areas taken u...

By analyzing the type and content of gas in oil, latent faults equipment can be found as soon possible, monitored at any time. In this paper, a degassing device based on headspace method is designed. The oil circuit adopts way pump battery valve to complete inlet discharge. Through stirring, dissolved reach dynamic balance gas-liquid two-phase, so realize rapid effective separation oil. At same...

Crude oil fouling of the equipment surfaces is a troublesome issue which leads to operating difficulties, economic penalties, increased environmental impacts, and health and safety hazards in petroleum industry. With a rough estimation, a minimum cost of equal to 4 million barrels of oil/year is required to be invested to offset the costs of crude oil fouling in Pre-heat Trains of Iranian oil r...

The main aim of the article is to present design laboratory test equipment, which appropriate for monitoring efficiency oil filters and system evaluating technical life engine oils in terms possible extension service intervals. functionality designed equipment filtration motor was verified by a practical experiment with verification measurement assessment suitability hydraulic circuit elements ...

one of the important issues in the field of organizational decisions is determine the optimal time of use the equipment. managers should take proper decision to repair, rebuild or replace the equipment, so that the greatest benefit and the least cost to the organization. in the military, moving units, items, equipment and manpower, is the part of the logistics system mission. in this regard, th...

This paper investigated the feasibility of developing alternative insulating nanofluid from a mixture Jatropha and Neem oils into which compositions 0.2 to 1.0 wt% titanium oxide nanoparticles were dispersed. FTIR, SEM–EDX XRD analyses carried out. The DC AC breakdown voltages measured analysed using Weibull statistical tool. In analysis, it was observed that characteristic field strength PJO i...

Power transformers are still equipment of primary importance within power grids. The recent paradigm changes registered in the field energy require interconnection electrical grids much larger areas, even up to level an entire continent. In this context, knowing state and that is essential aspect ensure safe operation conditions. present work related vulnerability oil–paper insulation systems d...
