Ethylene Yield from a Large Scale Naphtha Pyrolysis Cracking Utilizing Response Surface Methodology

A Fuzzy Decision-Making Methodology for Risk Response Planning in Large-Scale Projects

Risk response planning is one of the main phases in the project risk management and has major impacts on the success of a large-scale project. Since projects are unique, and risks are dynamic through the life of the projects, it is necessary to formulate responses of the important risks. The conventional approaches tend to be less effective in dealing with the impreciseness of risk response p...

Coke Inhibition During Naphtha Pyrolysis

Simulation and Optimization of a Naphtha Thermal Cracking Pilot Plant

In thermal cracking plants, it is desired to apply an optimal temperature profile along the reactor to minimize the operation cost. In this article a simulator is developed by the use of a mathematical model, which describes the static operation of a naphtha thermal cracking pilot plant. The model is used to predict the steady state profiles of the gas temperature and product yields. Using ...

Optimization of Biodiesel Production from Castor Oil Using a Microwave Via Response Surface Methodology (RSM)

The purpose of this research work was to investigate the optimum operating conditions for biodiesel production from castor oil using a microwave. The Box–Behnken design of experiment was carried out using the Design Expert 7. A response surface methodology (RSM) was used to analyze the influence of the process variables (molar ratio of methanol to castor oil, catalyst concentration, reaction ti...

Increasing in the Extraction Yield of Environmentally Friendly Antifouling Agent from Pseudomonas Aeruginosa MUT3 by Response Surface Methodology (RSM)

In the present study, the solvent-solvent extraction of phenazine 1-carboxylic acid (PCA) as an environmentally friendly antifouling agent from pseudomonas aeruginosa MUT3 culture was investigated. Accordingly, after screening the extraction ability of various solvents, the combined effects of operating parameters such as solvent type (ethyl acetate, dichloromethane, and n...
