Production Plant Problem
Thursday, November 29, 2007

Normally, there’ll be less or no problem when a production plant is running smoothly. The supervisors and plant operators will be happy taking care of a normal running plant. The executives and engineers will monitor and optimize the processing parameters and ensure all utilities consumption such as water, electricity, steam, air, chemicals, natural gas, LFO, diesel etc are kept at the lower side. Once in a while there’ll be some problems such as leaking mechanical seal in a centrifugal pump or the level transmitter signal is not showing the right reading. Well, those are just some minor maintenance problem and could be easily entertained by the fitters and technician.

However, the big test is when the plant is stopping (or starting). A plant which is running smoothly will be interrupted and stopped (vice versa). The utilities consumption will be higher than normal. The temperature, pressure, flow rate will be disrupted. The plant operators will adjust certain processing parameters and also a few valves in order to stop the plant safely. The supervisor must properly and carefully coordinate the plant stoppage (or starting). At this point, the experience of the supervisor and operators plays a very significant role. Operating the stoppage (or starting) of the plant just by referring to the working instruction or manual will not be sufficient. For me, I’ll be confident if the stopping (and starting) of the plant is led by an experienced staff/supervisor. It’s even better if a senior executive or engineer could be around to monitor and oversee any problems or possible danger.

There were cases where serious accident/disaster occurred during starting up (or commissioning) of a plant. In a case 2 years ago in a plant next to my work place, the distillation column was caught by a blazing fire leaving 3 staffs crying helplessly for assistance on top of the highest roof above the column. We thought those unlucky staffs would lose their lives either by being burnt to death or from injuries after jumping down the 80 meter column to the ground (if they could not stand the heat). Luckily the fire brigade finally came and used their ladder crane system to fetch the trapped staffs from the almost melting structure. There must be something gone terribly wrong during that particular plant start up. That’s why we need to be extra careful and have ample manpower to assist on the plant stoppage or starting up.

In the next post, I’ll share 3 problems that we faced during our plant stopping and starting up last week, which made a lot of us miserable. You’ll learn these real problems that none of us ever expected it to happen. Check it out later…

Monitoring Activities Via Surveillance Video
Wednesday, November 21, 2007

A processing or production plant is a place which does not simply belong to anybody. It is strictly for authorized personnels such as production executives, process engineers, supervisors, plant operators, maintenance fitters, contract workers and others. Inside a production plant, there are hundreds and thousands of equipments, instruments and machineries.

As a process engineer, sometimes I need to see and monitor what is going on inside the control room or plant. It's easier to monitor the ongoing activities via a CCTV or a video surveillance system. There are moments where we need to check what the night shift was doing. There was also an occasion where a plant operator lost his handphone while charging it in the control room. After he realized his handphone was missing, he swiftly went to the place where the video surveillance is monitored to trace who took his belonging.

I believe not all production plants or factories install their own video surveillance system. I seriously think they should install them at various strategic spots for security reasons and monitoring any suspicious activities going around the premises. Even offshore platforms in the oil and gas industry are installed with video surveillance system.

One of the best in the business of professional grade video surveillance systems is EZWatch Pro Video Surveillance. EZWatch Pro video surveillance systems are among the most reliable and popular computer based video surveillance systems on the market. The products are of the highest quality, great value and fully supported by the factory.

The EZWatch Pro video surveillance systems is packed with complete feature that customers want. These include Easy Remote Viewing and Internet Monitoring, IP Camera Integration, Pre Alarm Recording, Area Select Motion Recording, Object Tracking, Missing Object Alarm, Dual Monitor Display, PTZ Auto-Tracking etc. The emergence of this technology have created a smarter video surveillance. This behavior recognition software adds intelligence to video as it is captured, recorded and analyzed. On top of that, the intelligent video offers improvements in video image enhancement even in extreme darkness.

Combining the intelligent video surveillance and its analytics software, a predefined detection of violation which occurs are automatically, in the form of real-time alarms/alerts sent to their responders. This keeps security personnel from continually having to watch monitors, particularly during the bulk of their shifts, when nothing is happening on screens. Surprisingly, this high tech video surveillance system is very easy to use. Most of the customers never open their user manual because the on-screen programming is so simple. They just look at the screen and it provides the customer a clear understanding of how to use it.

With such a good set of video surveillance system, we can ensure a more safer and secured working place. It's an investment that should be made by asset owner for the benefit of his business. In fact I may consider to use one for my house, just for the fun of it and off course - security purpose. The video surveillance system set is available for customers all around the world and will be shipped via UPS worldwide express.

Engineering Award
Monday, November 19, 2007

Would it be nice to be awarded handsomely for our good and brilliant effort? Would it be wonderful to be recognized by our peers and professionals from the same field? Have you been awarded for something before?

During my undergraduate studies, I was awarded “BP Computing Award 1998, University of Bradford”. I received a letter during summer informing and inviting me to attend a brief ceremony that was held that afternoon (I forgot the exact date and hall. That was about 9 years plus ago…). Initially I was puzzled and wandered why I received the award. Soon, I was informed that I got the highest mark for the subject “Computer Aided Process Engineering” and that led me to the award. Unfortunately, the prize was a just a gas handbook. I was hoping some sort of certificate or trophy which can be displayed on my wall or desk. Well, that’s fine; I just kept the official invitation letter to receive the award.

Few years after that, I’m a member (research officer and master student) of Chemical Reaction Engineering Group (CREG), a research group in Universiti Teknologi Malaysia. The group (which included me) won numerous local and international awards. I even kept a local newspaper cutting about our research. The photo of the head of research group, Prof. Dr. NASA, my colleague Ir. Dr. Didi and me beside the rig was printed. It’s fun and I’m proud of it. There was also documentary of our research group being shown in national television and off course I’m one of the stars in it. I acted performing some experiment to synthesize HZSM-5 zeolite catalyst (a type of silica alumina adsorbent).

Maybe you want to share some of your awards? Recognitions?

Other “Engineering Award” story occurred recently:

Bath: A chemical engineer who used a saucepan to develop a method of eliminating a source of radioactive waste has won a prestigious award. Professor Stan Kolaczkowski, of the University of Bath, was jointly given a highly commended award for services to the environment at the Institution of Chemical Engineers' gala dinner awards in London.

Terrifying Forklift Accident
Sunday, November 18, 2007

Does your workplace have a forklift? If yes, you better be extra careful. My workplace have a lot of forklifts. We need those forklift to carry our drums, heavier goods and equipments (motor/pump/spare parts etc). A forklift do not have the speed equivalent to a car, but it can be deadly because of its mass and sometimes human carelessness.

A forklift accident recently took place in Hampshire industrial estate, United Kingdom. A lorry driver was crushed to death by a forklift truck in a horror accident. The unlucky man, aged in his twenties, had driven his lorry to Budds Lane in Romsey to deliver sheet metal to the firm Wessex Medical Equipment. It is believed he was hit by a green Mitsubishi forklift truck while he was standing at the back of his lorry and suffered serious injuries. Continue read the full news...

Morale of the story: Be careful wherever you are. Death can happen anytime anywhere even though we're perfectly healthy person.

FROM THE CHEMICAL ENGINEER’S WIFE Part II
Wednesday, November 14, 2007

My Experience

Therefore, with a heavy heart, I filled the form to enroll in the PhD program in my own faculty. It was not hard for me to choose my supervisor because I choose a person that I have worked with before for my Masters dissertation. I know his personality and he knows mine. We clicked. However, at that particular time, my supervisor has ran out of research grant money and has already completed all his existing research. Therefore, I was assigned to choose my own topic. I was lost for a while…but not for long. I reflected on what I want to do in the future and where will I be positioned in the faculty. I am supposed to be specializing in ‘separation method’ in chemical engineering because I have been told to join the Separation Group of the faculty. To be more specific, I chose ‘crystallization’ as my specialized area because nobody in the faculty has mastered it.

During my Master’s dissertation, I researched on Palm Oil Crystallization in Producing Edible Oil. Therefore, I decided to continue in the same area but in different medium. I searched the Internet on crystallization and two of the areas caught my attention, metal glass crystallization and freeze concentration. After reading existing journal papers on both topics, I decided to do Freeze concentration. The reason: it’s cheaper, easier to understand and interesting. To conclude, the choosing process was not difficult for me because I know where I’ll be positioned in the future in my career.

For those who are just embarking in pursuing their PhD, here are some tips on how to choose a PhD topic.

Some Tips on Choosing a PhD Topic

1. First of all, do it with considerable care. Never lose sight of the fact that the PhD thesis should be the crowning achievement of your graduate education and will influence the direction of your career for many years to come.

2. It is of great advantage if the supervisors are willing to offer a choice or two or three dissertation topics. He/she will have a better overview of the field, knows the sources, and knows if the dissertation is doable within the allotted time frame. In effect, you will receive a crucial implicit promise that you will be closely guided along the way.

3. If you have good reason to be confident in doing research on the topic of your own choice if close guidance feels too restrictive to you, then proceed, but at least be forewarned that you can easily lead yourself on a wild goose chase.

4. It is imperative that both you and your supervisor be interested in your thesis topic. It is important that your mentor be interested in it because otherwise he/she might be much less motivated to help you.

5. Make sure that you do not start a dissertation on an unfamiliar topic. You should prepare some plans, even if tentative ones, well in advance and have a good overview of the topic before you commence active research.

6. Once you have chosen your thesis topic in collaboration with your supervisor, you should seek his/her active guidance to the utmost degree possible.

7. You will need to learn who the important scholars are in the field. Ask your supervisor who is working in your area, check their respective home pages on the Internet, and look for their working papers.

8. Whether you take a topic selected by your supervisor or develop your own, you have to be excited about the topic. I think it is more likely that this will happen if the topic is developed by you yourself, and coming from questions that you really want to pursue.

Inside McDonalds Meat Processing Plant
Tuesday, November 13, 2007

Everybody enjoys having a happy hour meal at the most famous franchise fast food restaurant - "Mcdonalds" and that includes me. In fact, I just had a nice dinner with my family 2 days ago in Mcdonalds Jaya Jusco Johor Bahru. As I googled about processing plant, I found this very interesting short video on how the meat for their famous burgers are processed. It is amazing to learn about their hourly quality control (QC) to ensure that the meat is tasty and juicy before packing it. The cleanliness factor is also strictly taken into consideration. After neatly, safely and cleanly wrapping the boxes (which contains the meat), they're distributed throughout the States.

Photo of the Day, Half Bridge Half Tunnel
Sunday, November 11, 2007

This picture of the day is not directly related to chemical engineering stuff, but I admire and appreciate the engineering behind it. The bridge (or should it be called tunnel) goes under the water to allow movement of ships. In order to pass, this bridge is half under the water. You drive down in the water and then come out on the other side. Truly marvelous piece of engineering. This bridge is between Sweden and Denmark. This picture was taken from the Sweden side.

300 , Design Project 2, 5S, NPSH, Pump - Rambling!!!
Sunday, November 04, 2007

I did not realize that the previous post about "Dipping Tape and Measuring Oil Tonnage" was my post number 300. That makes this current post that you're reading - number 301 in this Chemical Engineering World blog. Wow, it has been about 1 year and 3 months since I began blogging about my working experiences. I never expected , thought or dreamed this blog can be like what it is today. I never imagined to have more than 250 subscribers (at this moment and growing) for a technical chemical engineering blog. Thanks for your support.

This coming days will be a very hectic one for me. Tonnes of jobs and projects are waiting for me at work. We are going to have some minor 9 hours plant maintenance job. That job must be carefully coordinated in order to reach its objective - which is to improve the vacuum system in our plant process. I also have my plant monthly reports to complete and that is not easy as it need us to really focus and concentrate.

At the same time, the final year design project 2 file number 2 just arrived last Friday from a local university for me to read, digest, check, evaluate and give marks. I'm not sure when I can finish reading the design project report, but I was ordered to complete and email the marks by the end of this week... Well, I got to rush for that as well.

Oh yes... I almost forgot that I also need to conduct a 5S training for my plant operators. Maybe I'll arrange that on Tuesday afternoon.

Yesterday, on Saturday, I attended a very brilliant 3 hours training regarding pump. The training was conducted by one of our very experience and knowledgeable superior. From the training I discovered various types of pumps with various applications. We also did some real practice on how to calculate the Net Positive Suction Head (NPSH), based on our plant condition and situation. This was more advance from the basic NPSH that we learned in university. Furthermore, at university, we only know the theory, but this time, we experience and appreciate the NPSH knowledge... of course after we faced all the pump problems in the plant. We did learned other stuffs on why the pump trips, cavitate, air lock etc and it's relationship with the pump curve.

Lately, I also received few emails asking me some favours on various issues and also asked for some advice/assistance. I'm trying my best to entertain those request, but occasionally, lately, I'm too busy. I hope you can understand my situation. I'll try my very best to get back to some of you. I'm also struggling and fighting with time to keep this blog updated with fresh feed and content for you to read. That's why I really appreciate anybody who is willing to provide one or two post (or more... which is good) so that we can have this blog updated more frequently. If you have anything to share, it can be from your own experience or some new stuff that you learn or know, you're welcome to email it to me. If it suite this blog, why should I not post it in this blog for you?!!

I also have some post which I did mentioned to elaborate more. I'll continue them soon. Just bare with me for a while. Some of you have personally asked the continuation of those post. Sorry for the delay mate...

Dipping Tape and Measuring Oil Tonnage
Friday, November 02, 2007

In oil industry or oil plant, there are a lot of oil storage tanks available. It is vital for the oil company to know their daily oil stock simply because they are in the oil business. Therefore, they need to measure the oil volume and further work out its tonnage. They need to know the exact volume of oil and to do that there are various methods. One of the traditional method is by using a dipping tape.

What is a dipping tape? Sorry, I could not find a suitable and proper definition for it. My own definition would be a tape made of from stainless steel (can be other material as well) and has some sort of calibration along it (up to 15m, or 20m, it depends on your tank height) and it's used to measure the ullage in a storage tank (filled with oil/liquid). Does anybody have a suitable definition of dipping tape?

I guess the next question from you will be: What is ullage?

The amount which a tank or vessel lacks of being full.

is the empty space present when a shipping container is not full.

The space in a tank not occupied by its contents. Used as a measure of storage space still available.

I hope the ullage definition would give you some idea on the concept.

For each storage tank, there'll be some sort of calibration table. From it, we can know what is the volume of oil at certain height. The tank height is also recorded in the calibration table. So, in order to know the volume of oil, we substract the tank height from the ullage (which we get from the dipping tape measurement), and we shall get the oil level height. From there, we can already get the volume of oil and work out the tonnage (with the temperature reading available).
