CRYOGENIC GAS PLANTS

NGL RECOVERY
Our Cryogenic Natural Gas Plants are engineered to dry and recover Natural Gas Liquids (NGLs) for natural gas feedstock flow rates of 30 to 200 mmscf/d utilizing the Recycle-Split-Vapor (RSV) process, or the Gas Subcooled Process (GSP) depending on desired recovery
rates.
The facilities use turbo-expanders to achieve an ultra-low temperature allowing recovery rates of 95+% of the inlet stream’s ethane, 99.8+% of propane and 100% of the butane.
The plants come in configuration including inlet dehydration using molecular sieve equipment, cryogenic gas processing system, and turbo expander/ re-compressor skid.

Additional options such as a hot oil system, pipeline pumps, amine
treating, inlet and residue compression, and refrigeration equipment to meet specific application demands are available.

Differentiator Elements
 Molecular sieve dehydration
 Gas Subcooled Process for moderate ethane recovery
 Recycle-Split-Vapor process for ultra high ethane and superb propane and heavier hydrocarbons recovery
 Stainless steel de-methanizer
 Brazed aluminum heat exchangers;

» Up to 99% ethane recovery
 Up to 100% propane recovery
 100% butane recovery
 Effective recoveries in recovery and rejection modes
