Schools play a vital role in creating a greener future. They will likely be the first place most students encounter determined efforts to conserve energy and water or to reduce waste. The method used in this article is comparative and matching method, by using ISO 14001, OHSAS 18001 and ISO 50001 standards.  Implementing energy management along with other standards is the main objective of pres...

In present paper, dynamic behavior and control of a fluidized bed reactor for polyethylene production has been considered. A double active sites model for Ziegler-Natta catalysts is used for simulation of polymerization reaction. Hydrodynamic behavior of the bed is modeled using a two phase model including bubble and emulsion phases in which bubble phase has plug flow pattern with different...
