CAREER EPISODE – 1
A) Introduction
[CE 1.1]
This episode is about work performed on the production of biodiesel from sewage sludge. I worked on it to fulfil the requirements for a BE degree in Chemical Engineering from BMS College of Engineering, Bangalore. The project was started in Jul 2016 & ended in December 2016.
B) Background
[CE 1.2]
The main considerations for this project work have been the energy crisis and the grave environmental pollution caused by the use of fossil fuels. Another main reason is that sewage sludge contains lipids that can be converted into biodiesel via transesterification.
This process is subdivided into three steps: drying of sewage sludge, extraction of the requisite lipids, and transesterification.
[CE 1.3]
During my work in this project, I was responsible for the implementation of the following work tasks:
- Developed the experimental setup.
- Collected the sludge and dewatered it.
- Pretreated the sludge for liquid-liquid extraction.
- Extracted the lipid yield through the implementation of the Soxhlet Method.
- Extracted lipid by liquid-liquid extraction using a match mixer and a mechanical shaker.
- Verified the lipid yield through the implementation of the oil emulsion test and the free fatty acid test.

A) Introduction
[CE 2.1]
This report relates to my work on completing a thesis on Fault (Blockage) detection and analysis based on frequency response in vanadium redox flow batteries. I worked on this during my studies at the School of Chemical Engineering at UNSW, Australia. This project covered the period from February 2019 to Aug 2019.
B) Background
[CE 2.2]
With advances in technology over the years, renewable energy technologies have become increasingly significant. This has led to a decrease in reliance on fossil fuels for energy, resulting in a substantial reduction in greenhouse gas emissions.
Despite certain renewable energies possessing an intermittent nature leading to development of imbalances in the supply and demand and providing certain issues related to the quality and supply of power, the Vanadium Redox Flow Battery VRFB is considered an effective and viable solution to all these problems.
In this part of the project, I explain my work on a single-cell system to investigate whether the frequency-response approach is useful for detecting blockages in the cell, and then apply the same methodology to a multi-stack system.
[CE 2.3]
My main role in this project is described as follows:
- Performing research or reviewing related previous papers, and doing a literature review.
- Described a work methodology and followed it for timely completion.
- Performed a detailed investigation of cell blockage.
- Designed an experimental setup.

A) Introduction
[CE 3.1]
This report relates to my work on completing a thesis on Fault (Blockage) detection and analysis based on frequency response in vanadium redox flow batteries.
I worked on this during my studies at the UNSW School of Chemical Engineering, Australia. This project covered the period from February 2019 to Aug 2019.
B) Background
[CE 3.2]
In this part of the project, preliminary studies were conducted on a multi-stack system & assessed the variation in the results. From the experiment, I obtained positive results, and cell blockage was detected to some extent. In this phase, I have performed a static run on a multi-stack system and used a programmable electronic load to trigger rectangular signals.
