Kinetics and Mechanism of Thermal Decomposition of Cobalt _I   ABSTRCT The thermal decomposition of cinnamate complexes of cobalt (II), nickel (II) and copper (II) was carried out using thermogravimetry (TG), derivative thermogravimetry (DTG) and differential scanning calorimetry (DSC). The kinetics and mechanism of the decomposition process were evaluated. The different stages of decomposition were…

  MATURITY IN THE PETROCHEMICAL INDUSTRY FEATURES, MOTIVES & C ABSTRACT Petrochemicals give the highest value from crude oil and natural gas but suffers from maturity like any other business. Petrochemicals companies are promoting their business in the direction from oil & gas commodities. Specialities and life science. Reasons of maturity are expired patents, low…

  Maximization of Egyptian Gas Oil Production Through the Opti Abstract Gas oil is the major fossil fuel consumed around the world. Global gas oil consumption is rising at a steadily fast pace because of its higher combustion efficiency (versus gasoline). The annual increase rate of gas oil consumption in Egypt is 7 % whereas,…

  MODELING ASPECTS OF ACTIVATED SLUDGE PROCESSE PART 2, Mathem   Abstract Mathematical process modeling and biokinetics of activated sludge process were reviewed considering different types of models. It has been evaluated the task group models of ASM1, and 2, and 3 versioned by Henze et al considering the conditions of each model and the…

MODELING ASPECTS OF ACTIVATED SLUDGE PROCESSES PART 1, PROCE Abstract Process modeling of activated sludge flocculation and sedimentation reviews consider the activated sludge floc characteristics such as: morphology viable and non-viable cell ratio density and water content, bioflocculation and its kinetics were studied considering the characteristics of bioflocculation and explaining theory of Divalent Cation Bridging…

Modeling of Hollow-Fiber Membrane System During Ultrafiltrat ABSTRACT: The present study aims to evaluate the performance of hollow fiber membrane module during ultrafiltration of aqueous solutions. The model is represented by a set of differential equations for permeate and residue pressure drop and volumetric flow rates in the axial direction, beside the principle equations of…

  NATURAL GAS, INVESTMENT STRATEGIES IN AN UNCERTAIN WORLD ABSTRACT: Natural Gas investment projects in developing countries (of which Egypt is a typical example) are one of the key industries in the evolving and continually changing energy market. It seems clear that the natural gas industry today is no longer limited by national boundaries, and…

Optimum Design of Heat Exchangers Networks,Part-2, case stud   Abstract: In this paper the computerized framework introduced in part-1 for Heat Exchanger Network Synthesis (HENS) with optimality conditions of achieving the least operating and capital cost has been applied on an industrial atmospheric distillation unit existing in one of the Egyptian refineries . The application…

Optimum Design of Heat Exchangers Networks Abstract: In this paper, we have developed a computerized framework for Heat Exchanger Network Synthesis (HENS) with optimality conditions of achieving the least operating and capital cost. The framework of HEN design involves the development three-computer programs, which applied sequentially to design an optimum HEN. The first program {Automatic…
