in this paper, to address the effect of reactor performance and configuration of biodiesel production on subsequent process parameters (including mass & energy consumption, required facilities etc.) two diverse biodiesel production processes (from plant oil) were implemented/designed using aspen hysys v7.2. two series reactors were taken into account in these designs where in the first and seco...

this paper examines the causal relationship between energy use and real gdp for the period 1967-2002 in iran. the results of phillips- perron test indicate that the real gdp and the four categories of energy, i.e. coal, oil, gas, and hydroelectric energy are integrated of order one. besides, the johansen — juselius maximum likelihood co- integration tests imply the existence of granger causalit...

this paper surveys economic growth and energy consumption relationship by new econometric methods in different sectors of iran. this study uses panel error correction model and panel co integration and causality tests to investigate short run and long run relationship between energy and value added growth in different sectors of iran’s economy with regards to energy price in the time period of ...

Energy-efficient machining strategies are required to be implemented in daily practice to advance the competitiveness of the enterprises on global scale. Energy information, which currently not considered as an integral part of production data, is studied. A need is identified to integrate energy information into production program and solidify the knowledge for extensive reference. To effectiv...

This paper examines the causal relationship between energy use and real GDP for the period 1967-2002 in Iran. The results of Phillips- Perron test indicate that the real GDP and the four categories of energy, i.e. coal, oil, gas, and hydroelectric energy are integrated of order one. Besides, the Johansen — Juselius maximum likelihood co- integration tests imply the existence of Granger causalit...
