The purpose of this research is to evaluate the effectiveness of implementation Quality Management System (ISO 9001:2000) in gas processing plants of National Iranian Gas Company using balanced scorecard approach. More specifically, we chose the balanced scorecard framework to examine five well-known gas processing plants in National Iranian Gas Company from four different perspectives in order...

Refineries are a source of emissions of volatile hydrocarbons that contribute to the formation of smog and ozone. Fugitive emissions of hydrocarbons are difficult to measure and quantify. Currently these emissions are estimated based on standard emission factors for the type and use of equipment installed. Differential absorption light detection and ranging (DIAL) can remotely measure concentra...

Duckweed biomass is gasified in a thermochemical-based superstructure to produce gasoline, diesel, and kerosene using a synthesis gas intermediate. The superstructure includes multiple pathways for conversion of the synthesis gas to liquid hydrocarbons via Fischer−Tropsch synthesis or intermediate methanol synthesis. Low-temperature and high-temperature Fischer−Tropsch processes are examined us...

Methane is the second most important greenhouse gas (GHG) after carbon dioxide. Amount of methane emission from energy sector is increasing day by day with various activities. In present work, various sources of methane emission from upstream, middle stream and downstream of oil & gas sectors are identified and categorised as per IPCC-2006 guidelines. Data were collected from various oil & gas ...

The purpose of the present paper is that of researching the impact of corporate governance on financial performance, on a sample of 3 companies (Tamin Petroleum & Petrochemical Investment Co., Persian Gulf Petrochemical Industries Company and Parsian Oil and Gas Development Group), mainly from the chemical industry area, listed at Tehran Stock Exchange index, during the period 2011-2016. In thi...

Recently sulfolane has been detected in well water within the town of North Pole, Alaska. A plume was identified in groundwater, originating from a petroleum refinery, and the highest concentration measured in wells outside the refinery was 269 ppb as of January 2011. Due to the contamination, residents were being provided bottled water for use and additional wells were created outside the plum...

This paper presents an economic evaluation of gas to liquids (GTL) project using “South-Pars” gas field of Iran based on the latest actual performing GTL projects. Iran has the world’s largest reserves of natural gas and can satisfy the projected long-term market demand of GTL products which have lower pollution and higher quality than refinery products. The results of cost-benefit analysis sho...

background: the reliability and safety of gas refineries are strongly associated with the reliability of other parts of the system. defect and failure in one part of a system can cause total system breakdown or accident. the failure and damage in these equipment such as transformers and boilers results in not only the equipment damage and human injuries but also productivity reduction. the purp...
