NaTURaL GAS PROCESSING

 

Gas conditioning

Natural gas produced as free or associated with the oil caries normally traces of oil, water and some solid particles. Before any treatment to remove undesirable gas components, conditioning is done via:

• Feed gas separators.
• High energy separators.
• Decanters.
• Mist extractors.

Dehydration

 

  It essential to control hydrocarbon and water dew points of natural gas streams for the purpose of transporting the gas some distance for further treatment without the separation of harmful water phase. Several technologies are available to do that, depending on size and cost:

• Glycol dehydration system.
• Desiccant gas dehydration.
• Glycol-amine gas dehydration.
• Solid adsorbent dehydration system.

Hydrocarbon Recovery

 

   Recovery of heavy hydrocarbon components like natural gasoline, butane and propane can be achieved systems such as:

• Hydrogen purification by PSA.
• Jewel T  Hydrocarbon recovery.
• LTX hydrocarbon liquir recovery.
• Mechanical refrigeration.

 Sweetening

 

 Systems to remove contaminants in virtually any environment are of great importance. The most common contaminants in gas streams beside water are the acid gases, hydrogen sulfide (H2S) and carbon dioxide (CO2). Other contaminants often encountered include carbonyl sulfide (COS), carbon disulfide (CS2), and mercaptans (RSH). There are several processes available to us like:

• Paques  Bio-desulphurization process.
• Amine gas sweetening.
• SULFATREAT^® H₂S Scavenge.
• Cynara Membrane CO₂ Separation System.
