Simulation of a sachet water processing plant using an analogous electrical model

  This paper presents an electrical model for studying the process behaviour of a sachet water production plant. In this model, the mechanical components of the plant such as the connecting pipes, the water tanks and the water filter were represented by resistors, capacitors and an inductor, respectively. A state equation was developed as a mathematical model of the electrical circuit. In this equation,...

Performance of activated carbons in the catalytic wet peroxide oxidation (CWPO) of maleic acid

  Catalytic wet peroxide oxidation (CWPO) of maleic acid using palm fruit shell, peach stone and cashew nut shell as catalysts was investigated. Physical activation of pyrolised char with carbon dioxide was done at 900°C, 30 min holding time and heating rate of 20°C/min under nitrogen flowrate of 150 cm3/min. The activated carbons had maximum Brunauer Emmett-Teller (BET) surface areas of 389, 428 and...

Predictive modeling for an industrial naphtha reforming plant using a recurrent-layer artificial neural network

  In this research, a layered-recurrent artificial neural network (ANN) using back-propagation method was developed for simulation of a fixed-bed industrial catalytic-reforming unit, called Platformer. Ninety-seven data points were gathered from the industrial catalytic naphtha reforming plant during the complete life cycle of the catalyst (about 919 days). A total of 80% of data were selected as past...
