In this study, biodiesel production from castor oil has been investigated. Five independent variables including; methanol to oil (M:O) molar ratio, catalyst concentration, reaction temperature, time and stirring rate have been chosen to investigate their effect on biodiesel yield. Response Surface Methodology (RSM) via Rotatable Central Composite Design (RCCD) has been used to evaluate the influence...
Crude oil atmospheric distillation systems are an energy intensive processes; it was evaluated that the energy requirement for such plants is equivalent to a 2% of the total crude oil processed [1]. An existing crude oil atmospheric unit is very expensive to modify due its complex configuration and interactions, and existing constraints of structure, limited space area, matches, bottlenecked equipments,...
