This course contains the processes in a natural gas processing plant to provide products in the form of pipeline gas or liquefied natural gas (LNG). The learning method is in the form of offline/online lectures and case studies using natural gas raw materials taken from one of the gas plants in Indonesia. In its implementation, Unisim software is also used to be applied to several processes discussed in the lecture.

• Introduction and Terms in Natural Gas Processing

  • Overview of natural gas processing
  • Key terms and concepts used in the industry (e.g., gas conditioning, sweetening, dehydration)

• Physical Properties of Hydrocarbon Fluids

  • Understanding the physical properties of natural gas and hydrocarbon fluids
  • Key parameters: density, viscosity, compressibility, and phase behavior

• Hydrocarbon-Water System

  • Behavior of hydrocarbons in the presence of water
  • Emulsions, phase separation, and implications for processing

• Hydrate

  • Formation of hydrates in natural gas pipelines and processing plants
  • Methods for preventing and managing hydrate formation

• Dew Point Control Unit

  • Purpose and operation of dew point control units in natural gas processing
  • Controlling water and hydrocarbon dew points to prevent condensation

• AGRU (Acid Gas Removal Unit)

  • Overview of acid gas removal processes (e.g., amine gas treatment)
  • Techniques for removing CO₂, H₂S, and other contaminants from natural gas

• Absorption Dehydration Unit

  • Principles of absorption dehydration for removing water from natural gas
  • Design and operation of dehydration units using glycol or other absorbents

• Adsorption Dehydration Regeneration Unit

  • Adsorption-based methods for dehydrating natural gas
  • Regeneration techniques for adsorbents (e.g., molecular sieves, activated alumina)

• Heavy Hydrocarbon Recovery Unit

  • Processes for recovering heavy hydrocarbons (e.g., C5+ components) from natural gas
  • Techniques for separating and refining heavier fractions

• LNG Processing

  • Overview of liquefied natural gas (LNG) production and processing
  • Key steps: liquefaction, storage, transportation, and regasification
