Bleaching of Vegetable Oil using Organic Acid Activated Fuller’s Earth (Bentonite Clay)
Published In: GJRE Part: C: Chemical Engineering Volume: 15 Issue: 2 Vegetable oil is one of the basic food items which is consumed by almost every human being in this universe. Therefore quality of vegetable oil should be good enough so that it accounts for healthy life. In vegetable oil manufacturing there are four major steps involved which are neutralization, degumming, bleaching and deodorization. Among these steps bleaching is the very important and...
Analytical Study on Motion Behavior of Non-Spherical Particles in Incompressible Fluid with Presence of Electrostatic Force
Published In: GJRE Part: C: Chemical Engineering Volume: 15 Issue: 2 In this paper, the accelerated motion of non-spherical particles in an incompressible fluid in both the presence and the absence of electrostatic force was investigated. Differential transformation method (DTM) and a FORTRAN code was used to calculate the instantaneous velocity of particles. Regarding particles’ instantaneous velocity in the absence of electrostatic forc...
