1. Simulation, Control and Experimental Analysis of 1,3Butadiene Purification Unit

Rahbar Rahimi; Shirin Boulaqhi; Amir Ziarifar

Volume 13, Issue 4 , Autumn 2016, , Pages 33-45

Abstract
  Simulation of a process and analysis of its resulting data in both dynamic and steady-state conditions are fundamental steps in understanding the process in order to design and efficient control of system as well as implementing operational cost reduction scheme. In the present paper, steady and unsteady ...  Read More

2. Bubble formation on a single orifice in a gas solid fluidized bed using digital image analysis

A. Dehghan Lotfabad; S. Movahedirad; M.T. Sadeghi

Volume 13, Issue 1 , Winter 2016, , Pages 60-72

Abstract
  Digital Image Analysis (DIA) has been employed to characterize the time evolution of a bubble injected from a single orifice into a pseudo 2-dimansional gas-solid fluidized bed. The injected bubble diameter increased with the square root of time before detachment. During bubble free flight in the bed, ...  Read More

3. Modification of Montmorillonite and Prediction of Polymer/Clay Affinity Using Surface Properties and Lattice Model

Sh. Mehmandoust; M. R. Moghbeli1*; M. Dadban; H. Karimian

Volume 12, Issue 3 , Summer 2015, , Pages 41-54

Abstract
  "> Sodium montmorillonite (Na-MMT) was organically modified using 11- aminoundecanoic acid (AUA) and methacryloxyethyltrimethylammonium chloride (MAETAC) via cation exchange reaction. The effect of the modifier type and concentration on the structure and surface properties of the organically modified ...  Read More

4. Study on the Effect of Humidity on Electrical Properties of Copper-Silica Aerogel

N. Yasrebi; J. Moghaddas

Volume 12, Issue 2 , Spring 2015, , Pages 3-12

Abstract
  > Copper-silica aerogel was synthesized by the sol-gel method and was heated at 400, 500 and 600°C for 3 h in the air. The gained materials were named as sample (a), (b) and (c) respectively. Then all samples were characterized by FE-SEM, EDX and FTIR spectroscopy. For resistance measurements ...  Read More

14. Optimization of Integrated Low-Temperature Gas Separation Processes Using SA Method and Different Refrigerants
Volume 6, Issue 4 , Autumn 2009, , Pages 27-33

Abstract
  In low-temperature processes, heat rejected from separation columns is removed by refrigeration systems to heat sinks (reboilers & pre-heaters), process streams, other refrigeration streams, or external utilities. The need for efficient utilization and recovery of energy in sub-ambient gas separation ...  Read More

18. Study of Carbon Black Production with Optimized Feed to Predict Product Particle Size
Volume 4, Issue 1 , Winter 2007, , Pages 36-42

Abstract
  Carbon black or soot is a carbon rich material which is widely used as a modifier and filler. Usually carbon black is produced via thermal decomposition of heavy hydrocarbons. This process is too complex to be modelled fundamentally. In this study, the effect of reaction feed composition on the soot ...  Read More

19. Synthesis and Seeding Time Effect on the Performance of Nanostructure Sodalite Membranes
Volume 4, Issue 1 , Winter 2007, , Pages 54-70

Abstract
  > Secondary growth technique was successfully applied for the synthesis of nanostructure sodalite membranes with vacuum seeding on tubular α-Al2O3 supports. In the seeding process, a thin, uniform and continuous seeding layer was closely attached to the support external surface by the pressure ...  Read More

20. A Study of Flow and Mixing in Bubbly Gas-Liquid Pipe Flow Generated by a Grid
Volume 3, Issue 4 , Autumn 2006, , Pages 60-75

Abstract
  The spreading of a tracer in a bubbly two-phase grid-generated turbulent flow system is studied. In this work both particle image velocimetry (PIV) and planer laser-induced fluorescence (PLIF) are used to study the effect of the dispersed phase flow rate on the mixing characteristics of the tracer. The ...  Read More

21. A Detailed Investigation of Particulate Dispersion from Kerman Cement Plant
Volume 3, Issue 3 , Summer 2006, , Pages 65-74

Abstract
  The aim of this study was to investigate the particulate dispersion from Kerman Cement Plant. The upwind – downwind method was used to measure particle concentration and a cascade impactor was applied to determine particle size distribution. An Eulerian model, Gaussian plume model and an artificial ...  Read More
