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

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.
