15 Questions
What is the primary purpose of natural gas dehydration?
To prevent hydrate formation
What is the dew point of natural gas?
The temperature at which water vapor condenses from the gas stream
Which method uses a hygroscopic liquid to remove water vapor from natural gas?
Absorption (Glycol Dehydration Process)
What are the primary conditions promoting hydrate formation?
'Free' water present and high pressure
Why do purchasers typically require that gas and liquid petroleum gas (LPG) feedstocks meet certain specifications for maximum water content?
To ensure downstream operations are not hampered by water-based problems
What is the primary reason for the dehydration of natural gas streams?
To prevent hydrate formation in the gas stream
Why is the presence of water undesirable in most commercial hydrocarbon processes?
It promotes side reactions, foaming, or catalyst deactivation
Which process involves using a hygroscopic liquid to contact the wet gas and remove water vapor from it?
Absorption (Glycol Dehydration Process)
What is the primary condition promoting hydrate formation in natural gas?
Low temperature and high pressure
What does the dew point of natural gas indicate?
The temperature at which water vapor condenses from the gas stream
What is the primary purpose of the Sulfinol process?
To remove H2S, CO2, COS, and mercaptans from gases
What is a unique feature of the Sulfinol process compared to other absorption processes?
It uses a mixture of solvents, allowing it to behave as both a chemical and a physical absorption process
What kind of contaminants can the Sulfinol process reduce to low ppm levels?
Sulfur compounds in the product gas
What is a typical operating condition that can be accommodated by the Sulfinol process?
Vast ranges of treating pressures and contaminant concentrations
What is a feature of the Sulfinol process related to equipment size?
Smaller equipment due to low foaming tendency
