In order to maximize the profit of a biodiesel production plant, one has to decide the numbers of unit productions and the values of controller parameters. This study addresses the problem by examining various control loops and process configuration within a process superstructure. The problem is formulated as a dynamic Mixed Integer Nonlinear Problem and is subsequently solved by using the Dynamic...
Waste cooking oil is a potential alternative of refined vegetable oil for biodiesel production due to its low cost and elimination of its disposal problem. The concentration of free fatty acids (FFAs) in WCO dictates the type of chemical treatment required for biodiesel production: a single esterification reaction is considered at high content of FFAs, whereas, a combination of estrification and transestrification...
In this study, we produce biodiesel from jatropha oil through enzymatic synthesis in a re circulated packed bed reactor (PBR). A solvent free system by three stepwise addition of one equivalent molar methanol in each step was chosen for this study. The enzyme was Lipozyme IM, a 1, 3 regiospecific immobilized lipase from Mucor miehei. Initially, we scrutinized the appropriate amount of lipase by varied...
The ENERFISH project aims to demonstrate a new poly-generation application with renewable energy sources for the fishery industry. The distributed energy system utilizes cleaning waste of a fish processing plant to produce biodiesel. The biodiesel is used to produce the locally needed cooling/freezing and heating energy. In addition, a power surplus is generated for the electricity network or local...
