 Abstract

Algae have emerged as one of the most promising sources for biodiesel production. Biological materials can be utilized for the production of energy by burning of biomass in the production of biofuels. The lipid and fatty acid elements of microalgae are converted to biodiesel via a transesterification reaction with methanol in the presence of a catalyst, to produce mono alkyl esters, which is generally known as biodiesel or fatty acid methyl esters (FAME). Biodiesel has gained much attention in recent years due to its eco-friendly nature, non-toxic characteristics, biodegradability and lower net carbon cycle compared to conventional diesel fuels. In the current study, carried out at laboratory-scale, potential algal species Chlorella vulgaris were collected from Kerala and employed as a feedstock for biodiesel production. The biofuel was determined to confirm the presence of biodiesel by Gas Chromatography - Mass Spectroscopy (GC MS), Fourier-Transform Infrared Spectroscopy (FTIR) and Thin Layer Chromatography (TLC).

 Abstract

- In this work, a cascade-forward neural network model has been developed to represent a reactive distillation process used for the production of biodiesel from an esterification reaction between palmitic acid and methanol. In order to obtain data for the network, the parametric utility of an Aspen HYSYS prototype plant of the process developed using Distillation Column Sub- Flow sheet and Wilson model as the fluid package was utilized. The neural network model developed had six input parameters (palmitic acid feed temperature, palmitic acid feed pressure, methanol feed temperature, methanol feed pressure, reboiler heat duty and reflux ratio), and the output parameter was the molefractionofthebiodieselobtainedfromthebottomsectionofthereactive distillation column. For the training of the neural network model, six different random number generators (Messene twister, multiplicative congruential generator, multiplicative lagged Fibonacci generator, combined multiple recursive generator, shift-register generator summed with linear congruential generator, and modified subtract with borrow generator) were tried by varying their seed numbers from 0 to 70, and the one with best performance, together with the corresponding seed number, was selected for the development of the cascade-forward neural network. The results obtained from the training and simulation carried out for the developed model showed the good representation of the process by the developed model because the estimated sum of absolute error, mean of absolute error, sum of squared error and mean of squared error of the model, which were the performance criteria used, were found to be favourable and had values of 1.16E-02, 1.93E-05, 5.46E-07, and 9.10E-10, respectively. Also, the performance of the developed model in predicting the mole fractions of the produced biodiesel was found to be very good as the sum of absolute error, the mean of absolute error, the sum of squared error and the mean of squared error, in this case, were estimated to be 8.39E-03, 1.40E-05, 2.17E-07, and 3.62E- 10, respectively. In conclusion, cascade-forward neural network has been demonstrated to be very good in modelling this complex reactive distillation process for the production of biodiesel.

 Abstract

In the recent days, there is a drastic rise in population so the domicile demands a clean and hygiene society. The study is aimed to line out the non-standard (2nd 3rd stage of vegetables) in markets, into embodiments. Lack of exertion in non-standard vegetables yields the annihilation that can be pragmatic relatively. The present methodology of bio-degradable waste management might be sophisticated and arduous is not well suited for upgraded technologies. To overcome these limitations we hereby propose a schematized way of handling bio-degradable waste using android application and ETL (Extract, Transform, Load) tool. Once the non-standard vegetables are ready for further exertion (raw materials, recycling, manures) the vendors can register their quantity, level, and their collective blend. The agencies in need of these non-standard vegetables can refer to details and collect. ETL is used for escalation of business intelligence as they convoke data from heterogeneous sources, run the workflow spasmodically and keeps track of statistics.

 Abstract

Flow through microchannels are of substantial importance as on date due to its multi-dimensional applications in modern electronic industries, Micro Electro Mechanical Systems (MEMS) as well as micro biological systems and various other applications. Hence, systematic studied are required for proper understanding of the flow behavior within a microchannel. In the present work, fluid flow and heat transfer characteristics within a microchannel of rectangular cross section is considered. The reduced form of the Navier-Stokes equation is valid for flow within microchannel as well. Thus, the Navier-Stokes and energy equations subjected to slip boundary conditions are solved by adopting various approximate analytical techniques. The velocity and temperature distributions are obtained under slip boundary conditions. The results obtained have been presented along a particular section of the channel and compared with the numerical solutions. By varying the aspect ratio of the channel, the accuracy of different approximate techniques has also been compared. It is observed that the accuracy level for the velocity as well as temperature profiles obtained in each technique depends on the aspect ratio.
