More about Water Treatment Plant: Methods to Remove Taste and Odor

Last week and today I met some Water Treatment Plant vendors to discuss about technical clarification. Some engineers and my boss have discussed the possibility to reduce the money to purchase water treatment package and make the system more simple. The main purpose the technical clarification meeting was to inform vendors what we want in our Water Treatment Plant, to ensure that is possible, and to ask for quotation, of course.

My boss is a very intelligent chemical engineer therefore I learn much about Water Treatment Plant from him. The vendors also told us about technical consideration in their water treatment plant configuration so that we understand a bit the reason behind their configuration selection. Of course we want to choose vendor who can offer best price and acceptable water quality (mainly for boiler feed water). Read More

What is Redwood Viscocity

I just got a really embarassing experience as chemical engineer. Sometimes we deal with a really complicated problem and we can handle that. On the other hand, we handle a simple problem, but we can’t handle that. How if a chemical engineer can not convert the kinematic viscosity expressed in Redwood second into dynamic viscosity? That is my problem. It happened about two days ago. My boss apparently was really disappointed. Read More

How to Calculate Jockey Pump Capacity in Fire Fighting System

About two days ago, my colleague asked me about inconsistency in our design basis of fire fighting system of our on-going project. In our design basis, we stated that the capacity of jockey pump is 50 gpm (the capacity of main fire pump is 500 gpm for electric motor fire fighting and diesel engine fire fighting, respectively). But vendor who supply fire fighting package stated that they will supply jockey pump with the capacity of 25 gpm. It would be a problem if the Construction Management (the one who monitors and review the product of the project) notices this. The question that will be come up is are you sure the capacity of jockey pump (which is 25 gpm) is enough in case there is a fire? The question rises in my mind is

Today I got a very nice meeting about three upcoming projects in my company. One of them is Basic Engineering Design. The meeting was attended by several engineers from my company and the team from our client.

The Basic Engineering Design was follow-up of our previous meeting: pre-feasibility study. We had about one hour discussion about the topic and we faced one problem here: the possibility to change basic engineering direction. Some people debated about the topic and the rest of them wished to get decision faster. But for us, as chemical engineering consultants, we tried to think carefully but we hoped to move quickly.

Energy Audit Project: What exactly an energy auditor does?

One of my colleague yesterday (8/2) asked me what exactly an energy auditor do in energy audit project. It took a minute for me to answer that question because I did not involve directly into that project (I defined myself as expediter in this project, not as engineer. But since I am chemical engineer, I quite understand what we do in energy audit project).  About that question, I said an energy auditor does calculation of energy consumption per product, determine if the plant consumes too much energy or not, and give some recommendations to conserve energy. Is that an easy job? I don’t think so. It is not easy, but it’s simple. Read More

Water Treatment Plant: Typical Configuration and Processes

Since May 2012, I have been involving in an EPC (Engineering, Procurement, and Construction) project. In my opinion, it is a big project because the core business of my company are (but not limited) feasibility study, plant assessment, turn around, plant re-activation, etc.

The first job I need to perform was to create Piping and Instrumentation Diagram of Water Treatment Plant. It was quite challenging task because this is the first time I deal with P&ID and also the first time I deal with Water Treatment Plant. Read More

Understanding Steam Boiler and Its Process

Yesterday, I got an opportunity to attend technical confirmation meeting with steam Boiler vendor. Unlike previous meeting with pump vendor, our senior chemical engineer and also our general manager of operation who are also chemical engineer, attended too.

Last time I had a curiosity to have full understanding about Boiler, its configuration, process philosophy, and manufacturing philosophy. Attending this meeting was one of free learning to understand those issue. At least it stimulated my curiosity again. Read More

Chemical engineer’s Diary: How to Keep on Track

Working as chemical engineer in Project Management Company is sometimes difficult. The reason is, mostly, we, the chemical engineers, young one or old one, fresh one or expert one, have to handle more than one project. We called that system as matrix.

In my company, the newly come chemical engineer usually handle one project. Then, on the second or third month of working, they will start to handle at least two project simultaneously. Some people may not have difficulties to manage this. But, for me, it is very hard. Read More

Chemical Engineer’s Diary: How far I have grown?

About five days ago I got an email from my boss. He asked my opinion about working in this company. Honestly, I have been asking myself how far I have grown as chemical engineer who works as consultant. I found the answer was very hard. I am not quite sure I have grown a lot as chemical engineer.

I have been working in this company since November 2011, so it’s been nine months. I have involved in six projects, one pre-feasibility study project, one bankable feasibility study project, three energy audit projects, and one engineering project (make piping and instrumentation diagram mostly). Although my project is quite a lot, I think my chemical engineering knowledge improved slowly. This is regrettable, but I need will not stop to create many ideas to improve ability. Read More

Energy Audit : Its Business Potential

Energy Audit especially for buildings and plants is considered as a huge potential business for consulting company especially in Indonesia. The Indonesia ministry of energy and mineral resources has issued law No. 14 year of 2002 about energy management. The law said that every energy user which consumes more than 6000 ton oil equivalent (TOE) is required to implement energy management.

What is energy audit

Energy audit is evaluation process of energy utilization, identification of energy saving opportunities, and formulate recommendation and energy efficiency improvement. Energy audit is carried out at least to main energy consumers regularly once every three year.

Who does energy audit?

Energy audit should be performed by internal energy auditor or by accredited institutions. The energy auditor should have competence certificate based on Indonesia legislation. Read More
