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.

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

Rifka Aisyah 2 Comments

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

Rifka Aisyah 3 Comments

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

Rifka Aisyah Leave a comment

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?

Rifka Aisyah 2 Comments

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 especially for buildings and plants is considered as a huge potential business for consulting company especially in Indonesia.

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

Vacuum Belt Filter: Get to Know

Rifka Aisyah Leave a comment

Today (4/30), I asked my Boss if he wanted to join us to have site visit to Dawuan, Cikampek. One of our upcoming project will be Bankable Feasibility Study of Carboxymethyl Cellulose Plant. He told me that he basically liked travelling. I sensed something positive would be coming. However, he asked me to find a lot of information about Vacuum Belt Filter, to list the information required to design vacuum belt filter, and to find technical drawings of vacuum belt filter. It was a bit hard job to do. But, I feel a lot of fun. Read More

Oil and Gas Company vs Project Management Consultant Company

Rifka Aisyah Leave a comment

I have a nice colleague. In some ways, I like him so much. But in other ways, I don’t like him when he started talking too much while I got many jobs to do. But overall, I like him. We get along well since I started working here. He’s more than friend for me (but not in romantic way, of course). He’s not really close with me, but every time I see him, I always remember my Dad.

On Friday (20/4), I had a short and nice conversation with me. As usual, he asked me to do or prepare something for our upcoming project: Detail Feasibility Study of Sabah Ammonia Plant. In addition, he also asked me if I mastered Aspen(R) (this is different issue from the previous one). He said he’s preparing proposal of biomass pyrolysis and wondered what’s the limitation of that program.  Read More
