Welcome to Zaki Yamani Official UTM Website

Some Back Ground

I was inspired to choose chemical engineering when I first saw the chemical formula from my father’s chemistry book. The chemical formula shapes look fascinating and interesting to me.

My father is an organic chemistry lecturer in Universiti Teknologi Malaysia (UTM). When I was 14, I read his organic chemistry book and willingly learnt from it by myself. When I was 17, I wanted to have a career associated with chemistry. Back then, my first choice was chemical engineering and my second choice was biochemistry. To be honest, I was unaware of what chemical engineers do and what the industry is like. I could not imagine it due to lack of exposure and information.

After completing my high school education, I pursue my A-Levels and took 3 core subjects which are essential for engineering: Physics, Chemistry and Mathematics. Then I continued my degree in chemical engineering. I managed to get a place in Bradford University, United Kingdom. I was unlucky because in our contract, practical training or sandwich course is not included by our sponsors. Therefore, we don’t have any valuable practical and industry exposures. That doesn’t matter and I keep on studying until I graduated in 1999.

Post graduate – Research and Development

After completing my degree, I returned to Malaysia and was appointed as a research assistant for 5 months in UTM. I joined “Chemical Reaction Engineering Group” (CREG) which its main research was developing the single step conversion of natural gas to gasoline using zeolite catalyst. It was a very interesting topic and that encouraged me to further my chemical engineering masters degree in it. Hence, I then became a full time research student and my research title was “Optimization of Oxidative Coupling of Methane (OCM) Using Experimental Design”, which is part of the natural gas to gasoline research project. As a master’s student, I conducted a thorough research, synthesized catalysts, run experiments, optimized reaction, published technical papers, presented posters and participated in related science-technology exhibitions. I learned and used various analytical equipments such as X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infra Red (FTIR), Atomic Adsorption Spectroscopy (AAS), Nitrogen Adsorption (NA), Nuclear Magnetic Resonance (NMR) and Gas Chromatography (GC). Besides that, I developed my own experimental rig to study the reaction of natural gas and the catalysts that I synthesized. To optimize the experiment, I used “Response Surface Methodology” (RSM) – “Central Composite Design” (CCD) from Statistika software. The software enabled me to arrange my experiment systematically and I can easily obtain a model equation for the reaction. With CREG, we won numerous local and international awards from our research and inventions. It was such a great honor to be part of a successful research group.

Oil & Gas Exposure – Servicing Company

After completing my masters, I was offered a job as chemical technologist for a local oil and gas servicing company. In a year, I became a project/chemical engineer in the same company. My main task was to lead the “internal pipeline chemical cleaning” project for a local oil company. We basically have to assist the oil company to reduce corrosion activities inside the downstream pipeline and prolong the life span of it. The pipelines were chemically treated using degreaser and corrosion inhibitors; and physically cleaned using pigs. It was part of my responsibility to ensure correct formulations as well as performing necessary test to ensure the chemicals were fit to perform its duty. To efficiently and effectively monitor corrosion activities in the pipelines, we utilized latest corrosion monitoring techniques such as electronic resistant probe (ER) and field signature method (FSM).
zaki offshore

I was also in charged of the oil and gas specialty chemicals. I traveled to a number of offshore platforms in East Malaysia to conduct deoiler and descaler tests for their oil reserved. It was very challenging and fun performing those tasks. I love going offshore because the working hours are less compared to the amount of time we spent on the platform. The foods are marvelous and comparable to 5 star hotels. Entertainment and other activities such as television, movies, snooker, ping-pong, gymnasium and reflexology chair are made available for the platform dwellers. To be able to go offshore, I have to undergo Helicopter Under Water Escape (HUET) training and get myself an offshore passport.

With this job, I traveled extensively and visited neighboring countries, Singapore and Indonesia, for work purpose of course. In Kalimantan, Indonesia, I joined our company principal to conduct bottle test field trial for local oil company on their onshore oil rig. It was a very interesting and exciting assignment because I got to see how simple the setting of an onshore oil rig because in Malaysia we only have expensive and complicated offshore oil rigs/platforms.

Oil & Fats Industry – Refinery and Other Challenges

I love my oil and gas career but I was unfortunate because I could not continue being in that industry. The company management has bigger plans and they moved to Kuala Lumpur, the capital of Malaysia. I was instructed to transfer which I could not do because I don’t want to hinder my wife’s career establishment as a lecturer/researcher/consultant in UTM and we also have just purchased a house in Johor Bahru in the same year.

I seek for other jobs and managed to get one in a physical refining plant associated in the oil and fats industry. This is a whole new chapter and totally different from my previous job. I’m required to scan in and out every time we enter or exit the factory. Life is no longer as flexible as before. I don’t have ample time to do my work and that made me work longer hours and I always reach home when it’s already dark. I don’t really mind because it’s a new working environment and I know I have to learn as fast as possible. I set my target to know everybody around my circle of work as soon as possible.

My first task given by my boss was to identify and list down all the valves in the plant I’m in charged of. It was an interesting and good assignment. It made me traced the entire pipeline from the feed tank to the plant and to the product tank. I learned a lot of stuff regarding valves. I know and understand various types of valves, brand/ origin, sizes, spare parts, principle/operation, tag number etc. In addition to that, indirectly, I learned about the plant process and operation. That was just the beginning.
Being in a process plant is a perfect place to learn and put in practice your unit operation knowledge. It also gave me a better comprehension on what process control is all about. I learned about other supporting units like heat exchangers, cooling towers, boilers, utility boilers and much more. The learning curve continued everyday and never stopped.

Not only that I learn about all the technical stuff, handling manpower and conflict is another challenging area that I made myself good at. Manpower is not an easy matter to deal. Some of my down line manpower never experienced any disciplinary action taken when they violated certain laws such as coming in late and simply not coming to work. Despite a series of reminder and warning, the bad attitude still continues. I could not stand it. With the support of my senior colleague, I enforced the discipline and forced them to obey. I gave the problematic staffs some disciplinary action. I want them to learn some lesson and be more serious on their responsibility and work.

During plant shut down or some called it turn around, I learned a lot. Techniques on ensuring the fastest and effective way to cool down the plant, managing and coordinating a team of people to service the plant, conducting air test, steam test and driving the plant start-up are among some knowledge I acquired during 4 shutdowns of my plants.

Academia and Research

1st July 2008 was the day I reported duty as a lecturer. It’s a new career that I love and endure. I learned that being a lecturer demands me to be more discipline, because the role of the huge role as a lecturer. A lecturer does not only lecturers but they have to research,

A Little Something from Me

There are a lot more to share, but it’s impossible to include everything here. I’m glad to have experienced chemical engineering in three different areas; research (academics); oil and gas; and oil and fats. Each area has their own challenges, advantages and unique.

Being very vague about the chemical engineering industry during my student life urged me to improve the situation. Wouldn’t it be nice if somebody can tell and share what they can expect from the industry? It will be some sort of a chemical engineering informal education for the students and other junior engineers. That is why despite of my busy life as a process engineer, I progressively and continuously share some of my experiences in my “Chemical Engineering World” blog that I created on July 2006. A year after that, I created Chemical Engineering Net 2.0 . I sincerely hope it can provide at least some useful information for fellow young chemical engineers. I believe it’s a good thing if other professional and practicing engineers out there can do the same for others to benefit. It will be a great contribution.

Thermodynamic Analysis of Hydrogen Production from Methanol-Ethanol-Glycerol Mixture Through Dry Reforming

Zaki Yamani Zakaria, Mazura Jusoh, Ramli Mat, Mohd Johari Kamarudin, Jega Jewaratnam

Abstract. Thermodynamic properties of methanol-ethanol-glycerol dry reforming have been studied with the method of Gibbs free energy minimization for hydrogen production from methanolethanol-glycerol mixture. Equilibrium compositions were determined as a function of CO2/methanol-ethanol-glycerol molar ratios (CMEG) (1:6-6:1) where methanol-ethanol-glycerol is 1:1:1; reforming temperatures (573-1273 K) at atmospheric pressure (unless stated otherwise).
Optimum conditions for hydrogen production are CMEG 1:6, temperature 1273, 1 bar pressure. This point is also optimum for the production of synthesis gas. Higher pressure and higher CMEG ratio does not encourage hydrogen formation. Under identified optimum conditions, carbon formation can be thermodynamically inhibited. Nevertheless, the carbon yield can be reduced through reforming at higher temperatures.

Reforming of carbon dioxide for syngas production over modified nanocatalyst

Executive Summary of Research Proposal

Solar reduction of carbon dioxide (CO2) to renewable fuels offers solution to greenhouse gas mitigation and alternative energy source. The research is focused on mitigation of greenhouse gas (GHG); instead of sequestration, CO2 will be reused as a carbon source for the production of fuel for alternative energy supply. In this proposal, solar reduction of CO2 to syngas over nanostructured photocatalysts is presented. The photocatalytic CO2 reduction to syngas gas over nanostructured photocatalysts and using wire mesh support is the new innovation employed to produce syngas and hydrocarbons. Ultimately, the technology developed has prospect to be used as a prototype portable energy producer for solar fuel applications.

Offshore platforms – is this where you are going to work?

This post is intended for my chemical engineering students.

Do you want to work on offshore rigs / offshore platforms like these?

PlatformHollyAll oil drilling into the South Ellwood Offshore field takes place from Platform Holly, about two miles offshore in state waters. It is very cold here.

Thermodynamic analysis of hydrogen production from ethanol-glycerol mixture through dry reforming

Z.Y. Zakariaa,*, M. Jusoha, A. Joharia, M.A.A. Zainia, F.H. Kasimb

Thermodynamic properties of ethanol-glycerol dry reforming have been studied with the method of Gibbs free energy minimization for hydrogen production from ethanol-glycerol mixture. Equilibrium compositions were determined as a function of CO2/ethanol-glycerol molar ratios (CEG)(1:1-12:1) where ethanol-glycerol is 1:1; reforming temperatures (573-1273 K) at different pressures (1-50 bar). Optimum conditions for hydrogen production are temperatures between 1073 and 1273 K and CEG of 1:1 at 1 bar pressure, whereas temperatures above 1073 K and CEG ratio 1:1 and 1 bar are suitable for the production of synthesis gas. Higher pressure and higher CEG ratio does not encourage hydrogen formation. Under identified optimum conditions, carbon formation can be thermodynamically inhibited

THERMODYNAMIC STUDY OF CATALYTIC CONVERSION OF GLYCEROL STEAM REFORMING TO OLEFINS

Executive Summary of Research Proposal

Glycerol, an alcohol and oxygenated chemical byproduct from biodiesel production, has enormous potential to be converted into higher value-added fuels and chemicals. Due to the alarming excessive production of glycerol worldwide that have triggered environmental concerns, and the importance of olefins in the industry, it is therefore essential to explore the process of glycerol-to-olefin (GTO) in greater depth. This is mainly due to the fact that no dedicated study concerning GTO has been performed. Detail catalytic study has been previously studied and results are promising. However, there is a need to explore GTO in bigger perspective. In order to pursue this, complex thermodynamic analysis via simultaneous dehydration, dehydrogenation and deoxygenation of glycerol at various temperature, pressure and flowrate will be investigated. Empiral models will be used to generate thermodynamic data analysis. The result from this study will be a novel thermodynamic analysis of catalytic conversion of glycerol to olefins via complex reaction network.

DEVELOPMENT OF NEW SUSTAINABLE ACYL ACCEPTOR FOR BIODIESEL PRODUCTION FROM PFAD

Executive Summary of Research Proposal (PY/2014/02061)

Biodiesel is a clean burning fuel produced from renewable domestic sources such as vegetable oils and animal grease. It is biodegradable, non-inflammable,
non-toxic and has a favorable combustion–emission profile, producing much less carbon monoxide, sulfur dioxide and unburned hydrocarbons than
petroleum-based diesel. The production of first generation biodiesel has grown tremendously over the past decade. InMalaysia’s context, the government has
encouraged the production of biodiesel by providing numerous incentives. In 2006, 60 biodiesel manufacturing licenses were approved. Unfortunately, almost all
biodiesel plants utilizing vegetable oil as feedstock were later forced to shut down their operation due to the sudden increasing price of vegetable oil. As a result,
substantial number of biodiesel plants were left idle, some even sold as scrap metal. Such scenario could be overcome by utilizing a cheaper and sustainable
feedstock. Palm fatty acid distillate (PFAD) could be the answer to a commercially viable biodiesel production. Hence, production of fatty acid ester (FAE) from
PFAD containing high free fatty acids (FFA) was investigated in this work. Batch esterifications of PFAD were carried out to study the influence of reaction
temperatures of 70–100 °C, molar ratios of sustainable acyl acceptors to PFAD of 0.4:1–12:1, quantity of catalysts of 0–5.50% (wt of catalyst/wt of PFAD) and
reaction times of 15–240 min. Optimum conditions, reaction kinetics and mass transfer activities will be investigated. It is expected that the amount of FFA to
reduced from more than 90% to below 5% at the end of the esterification process. FAE will be further purified with alkaline medium and the final biodiesel product
will be tested in accordance to quality standard ASTM D6751-02.
