Coal Bed Methane for the Future of Gas Reserves in Indonesia

Coal bed methane for the future of gas reserves in Indonesia is one topic explained in BUMI Bulletin published by SKK Migas (Indonesia Special Task Force for Oil and Gas). This topic is very interesting because I never considered coal bed methane (CBM) as source of gas until now. CBM is hydrocarbon formed and kept in source rock, it does not move or migrate. In Indonesia, CBB reservoir is very wide and its resource and reserve is large. Read More

My First Webinar: Sustained Heat Transfer Fluid Performance

Last time, I had an opportunity to participate in a free webinar held by Chemical Engineering Online. Topic of the webinar was how to sustained heat transfer performance.

I was eager to participate in this webinar because of three reasons. First, the webinar was practical. Second, speaker of webinar was from Therminol, which is one of heat transfer fluid. Third, I indirectly was heat transfer fluid user for two projects. So that, I need to understand about this topic if there is application opportunity in the future.

The first project I used heat transfer fluid was in Rosin Plant and Its Derivatives in Pemalang. The heat transfer fluid was used as heating medium in reactors. The second project was in Senoro Gas Development Project in Central Sulawesi. There are acid gas removal, dehydration unit, and stabilizer that need heat transfer fluid as heating medium. Read More

Renewable Energy Resources: Wave, Tidal, and Ocean Thermal Energy Conversion

The other type of renewable energy resources that come from ocean are wave energy, tidal energy, and ocean thermal energy conversion.

Wave Energy

Wave energy is a type energy obtained directly from surface wave or surface wave under pressure. The waves are generated from winds blowing from the surface of sea or ocean. Wind itself is a function of temperature and pressure differences across the globe caused by distribution of solar energy.

Wave energy carries kinetic energy and gravitational potential energy. The energy is a function of height and period of waves. Wave Energy Converter (WEC) is used to convert wave energy into electricity. Read More

Where will my blog go?

I feel guilty to myself because I have broken my commitment: write and update this blog at least twice a week. So here I am, updating this blog. However, this post will be about where will my blog go.

I have listed several topics related to chemical engineering and general engineering. The topics was selected from google keywords and there are some topics that related with my previous works. I really wanted to make the post about those topics, but again I am afraid if my post would not be interesting.

I have checked how people came to my website and what they are looking for. Read More

Renewable Energy Sources: Geothermal and Biomass

In previous post, I shared brief overview about common renewable energy sources, such as solar power, wind power, and hydro power. In this post, I want to continue sharing about other renewable energy sources, which are geothermal, biomass, and energy sources from sea (wave, tidal, and ocean thermal energy conversion).

Geothermal Energy

Geothermal energy is renewable and offer more advantages than other renewable energy sources, such as hydro, wind, bio energy, biomass, and wave energy. It has high degree of availability, low land use, insignificant dependence on weather conditions, and comparatively low visual impact.

Global installed capacity of geothermal power has reached 14.4 GW, with the US as the largest geothermal country so far. Read More

Renewable Energy Sources: Solar, Wind, and Hydropower

Renewable energy is increasing around the world. This is because energy from fossil fuel becomes scarce. In Indonesia, based on RUPTL 2018, government plant to increase geothermal energy source from 5% in 2018 to 12% in 2025. The percentage of other renewable energy is 0% in 2018 to 2% in 2025.

What is renewable energy? Renewable energy is generated from sources that naturally replenish themselves and never run out.

Renewable energy could be alternative to combat with climate change because it does not generate direct greenhouse gas emission. The only emission that renewable energy generate is indirect greenhouse gas emission, which are from installation, operation, and maintenance. Read More

Potential geothermal projects in Indonesia

Potential Geothermal Project in Indonesia

Today I stumbled upon Investment Catalog while searching for certain information. The catalog was issued by Ministry of Energy and Mineral Resources, Republic of Indonesia. And guess what? I found something interesting: potential geothermal project in Indonesia.

The catalog was actually 2017 version. However, I think it is still quite relevant.

For you, who are consultant like me, EPC contractors, vendors, or licensors, you may be interested on this information. You can download the publication to read detail information about those projects. In this post, I want to share you potential geothermal project in Indonesia and its status based on publication on media.

There are six potential geothermal projects in Indonesia. Those are geothermal project in Gunung Galunggung , Gunung Hamiding, Gunung Wilis, Gunung Simbolon Samosir, Graho Nyabu, and Gunung Geureudong. Some of the name are familiar for me. Read More

Several Natural Gas Dehydration Methods and Range of Application

In almost every gas processing plant, there will be natural gas dehydration unit. Sometimes, it is called dehydration unit (DHU) or dehydrator. When, I was working in Tripatra and involving in Senoro Gas Development Project, the facilities consisted of dehydration unit as one of them.

Natural gas dehydration unit is an important facilities in onshore and offshore gas processing plant. Its function are:

  • To mitigate risk of water condensation, which leads to flow capacity issues (pipeline clogging and blocking)
  • To prevent hydrate formation or to minimize corrosion
  • To ensure smooth operation in downstream facilities. For example, gas pipeline is usually required 4-7 lb/MMSCF water content (87.2-152.6 ppm). For cryogenic unit (to produce LNG), water content in gas shall be less than 1 ppm. For CNG plant, before entering compressor unit, water content shall be reduced to maximum 3 lb/MMSCF to meet product specification.

How to be a Creative Writer

Two weeks ago, I got an amazing opportunity to participate in Bandung Creative Writer Festival, an event organized by KPKers (Creative Writers Community).

In this event I learnt how to motivate ourselves to be consistent in producing writings, how to gain ideas for our writings, and many more.

There are three speakers in this event, which are Jumadi Haryadi, who gave tips and trick to easily write something (we even practiced it in the event), Pak Adrie Noor, who has published books abroad, and Pak Ali Muakhir, who has wrote many kids and teenagers books.

Motivation First!

We write because we have motivation to write. What is your writing motivation? What your motivation is will drive you to be a lasted writer or temporary writer.
