Reduction of energy consumption and CO2 emissions are recognized as important issues in today’s world. In addition, oil and gas companies are looking for ways to increase their capacity and maximize system uptime in order to meet the global energy demand. To realize these goals, oil and gas facilities are looking for 261 STUDY OF LARGE VSI DRIVE SYSTEM FOR OIL AND GAS INDUSTRY

the effect of economic growth and free trade on environment and transnational pollutions is one of the most important current discussions in the field of environmental economics. nowadays, the economics, social and developmental consequences of the climatic changes around the world is increasingly accepted and approved. in fact, the environment is considered as one of the key elements for susta...

Regarding the increased energy consumption of the processes at the operational units in the National Iranian Oil Company, the present study analyzed energy consumption at one of the gas refineries. In this refinery, which is the main supplier of Fajr Jam refinery for the national gas network, as well as an injection into the oil fields of the Iranian South oil company, the pressure of gas after...

the aim of this paper is to assess the adaptation of iran’s energy policies to the kyoto protocol. in the past two decades, iran has experienced a considerable increase in greenhouse gas (ghg) emissions; in 2013 it was the world’s ninth largest emitter. although adapting to this protocol in iran’s energy and climate policies seems vital and urgent, its recent status is not promising. this paper...

This study explores the inter-relationships among economy, energy and CO2 emissions of 37 industrial sectors in Taiwan in order to provide insight regarding sustainable development policy making. Grey relation analysis was used to analyse the productivity, aggregate energy consumption, and the use of fuel mix (electricity, coal, oil and gas) in relation to CO2 emission changes. An innovative ev...

introduction energy is one of the most important commodities that make up a large proportion of international trade. among all the countries in the world, iran is known as semi-industrial developing country which is rich in energy such as non-renewable energy in particular fossil fuel. use of energy affects the environment in various forms of pollution. in the agricultural sector, the fao repor...

Global warming is attributed to increasing greenhouse gas emissions and mounting concentrations of carbon dioxide and other gases in the atmosphere. Since the middle of the 19th century, increasing worldwide anthropogenic activity is said to have given rise to a steady increase of carbon dioxide in the atmosphere. This is corroborated by direct measurement of CO2 concentrations at Mauna Loa Lab...

an increase in energy prices will decrease the fossil fuel consumption; on the other hand, the cost-push will encourage technology improvement for firms and households. these changes will affect the emission level.this paper studies the changes of yearly pollutant emissions after an energy price reform in iran. we apply a computable general equilibrium model which consists of 7 energy goods (el...

the continuous improvement of eaf performance is crucial for the increase in productivity and cost effectiveness and to render an environmental friendly process. rhi supports these targets by providing a diverse range of refractory and process solutions. chemical energy in practical operation by injection of gaseous media like oxygen and natural gas, and solid materials like carbon have become ...
