Get to Know Toothpaste Composition and What The Function Is

Today I bought a toothpaste from GlaxoSmithKline and got interested in its composition. I actually gained interest in reading composition of various things, but never answered what their functions. In this post I want to share you what I googled about the function of every component in toothpaste. Each toothpaste may have different toothpaste composition. I used this toothpaste brand for example. Please note, this post is not meant to encourage you to buy the product :D. Read More

Predicting Holding Time of LNG in Storage Tank Without Venting

In this post, we use vacuum insulated type LNG storage tank when we don’t want to deal with boil-off gas handling. The storage tank have design pressure as high as 6-10 barg. When we store LNG in the LNG, boil-off gas will be generated due to heat leak to tank. Increasing temperature of LNG will increase total volume of LNG and vapor in the tank, thus increasing its pressure.

This phenomena leads to a simple question, “How long can LNG storage tank keep the vapor before PSV works?” Read More

Typical Process Diagram for Small LNG Regasification (Part 2)

As mentioned in part 1, small LNG regasification facility typically consists of LNG unloading facility (which can be flexible hose or marine loading arm), LNG storage tank, LNG sendout pump, ambient air vaporizer, and metering. In part 1 we already discussed about LNG unloading facility and LNG storage tank. In this part I want to share the rest of them.

LNG Sendout Pump

LNG sendout pump is used to increase pressure of LNG before being sent to vaporizer. In LNG facility, there are two most common type of pump: submerged centrifugal pump and reciprocating pump.

Submerged centrifugal pump is used when LNG flowrate is high but the pressure in low to medium. Meanwhile reciprocating pump is used when the flow is low but the pressure is high. Read More

Typical Process Diagram for Small LNG Regasification (Part 1)

Today I want to share you Typical Process Diagram for Small LNG Regasification. For your information, small LNG regasification is very useful to be built in remote location where power supply is very limited.

Typically main equipments installed in Small LNG Regasification are unloading facility, LNG storage tank, LNG pump, natural draft ambient air vaporizer, and metering system. Read More

LNG Value Chain

My Current Project: All LNG!

Since the end of November 2015, my project was about LNG. Now, I also work with LNG. Totally my project related to LNG was three projects. Do you think that’s quite awesome?

I have done two LNG regasification project for power plant. Currently, I’m working on LNG terminal project and LCNG/LNG station. My first LNG project was very challenging. Not only because that was my first LNG project, but also the degree of difficulty and total regasification location. The first project involved 21 locations in Central Region of Indonesia. So, it was very tiring project. Read More

A Year Ago, A Year Ago

Actually more than a year ago (exactly 16 months ago), I wrote this post about how happy I was because of resigning from my first company. Then, now I moved again to another company. Still, I’m working in consultant company.

I moved to a company in my home town, Bandung, Indonesia. The difference between this company and previous company : this company’s business is basically ENGINEERING. So, I’m working in office mostly. But last week I spent almost my week in Oil Center, Jakarta.

How do I feel? Read More

Piping Basics

I am getting a really nice and free piping bulk material training in my company. It is a really rare for me to get such training so I won’t let it pass without meaning. The training was actually intended for supply chain staff. Although I am not one of them, my boss let me participate in the training.

Five days ago was a second meeting. It was not as good as the first time because we started to learn technical matter although it’s only the basic. Since there will be a test and I don’t want to put my face on shame, I need to learn more to gain the same understanding as those supply chain staffs.

I just got a nice, simple, and understandable presentation about piping basics. I really enjoy the presentation and I hope you too.


Problems in Secondary Copper Smelter: Possible Causes and Alternative Solutions

Recently I learnt about secondary copper smelter, the problems raised due to the processes, and what alternative solutions are. The motive was very clear: I need to prepare for the upcoming project. As already describled here, a process engineer is responsible for the process during project preparation and project execution. And that’s exactly what I am doing right now. Read More
