  • Sensitivity Analysis of Water Flooding Optimization by Dynamic Optimization 

    Gharesheiklou, Ali Asghar؛ Mousavi-Dehghani, Sayed Ali (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2007-03-01)
    This study concerns the scope to improve water flooding in heterogeneous reservoirs. We used an existing, in-house developed, optimization program consisting of a reservoir simulator in combination with an adjoint-based ...

  • Prediction of Minimum Spout Velocity and Moisture Distribution of Ammonium Perchlorate Particles in a Spouted Bed Dryer 

    Kalbasi, Mansour؛ Bahramian, Ali Reza؛ Khorshidi, Jamshid (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2007-03-01)
    Ammonium perchlorate particles have been dried in a laboratory spouted bed dryer (screen-bottomed type) which is categorized as a fluidized bed dryer. The solid particles obtained in this process of drying were ...

  • Biodegradation of Effluents from Dairy Plant by Bacterial Isolates 

    Maghsoodi, Vida؛ Samadi, Akbar؛ Ghobadi, Zahra (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2007-03-01)
    Micro flora of the effluents from a dairy factory in Tehran(Pegah Dairy Processing Plant) were isolated and screened for their ability to reduce the organic matter content and COD of the effluents. 10 bacteria ...

  • Isolation and Characterization of Polygalacturonase Produced by Tetracoccosporium sp. 

    Aminzadeh, Saeed؛ Naderi-Manesh, Hossein؛ Khajeh, Khosro؛ Soudi, Mohammad Reza (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2007-03-01)
    Thirty-five fungal strains which isolated from vegetable wastes, were screened for the use of polygalacturonic acid as the sole carbon source. Twenty-five isolates were positive for polygalacturonase activity in cup-plate ...

  • Prediction of Hydrate Formation for the Systems Containing Single and Mixed Electrolyte Solutions 

    Shabani, Mohammad Mehdi؛ Rashtchian, Davood؛ Ghotbi, Cyrus؛ Taghikhani, Vahid؛ Khayat, Ghazaleh (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2007-03-01)
    In this work the effect of electrolytes on hydrate formation was investigated. To do so, a new model was used in predicting the hydrate formation conditions in presence of both single and mixed electrolyte solutions. ...
