High Ethane Extraction & LPG Recovery

CB&I has pioneered technical developments and design innovations that contributed to establishing the cryogenic turbo-expander process as the technology of choice for deep ethane and LPG recovery from natural gas. 

Fractionation

CB&I has designed and built NGL fractionation plants with capacities ranging from 10,000 to 74,000 barrels per day in locations around the world and products include ethane, propane, iso-butane, normal butane and pentanes.

Gas Conditioning & Treating / CO2 Removal / Recovery

CB&I’s Randall Gas natural gas processing technologies include extensive gas conditioning and treating capabilities, including the removal of mercury, CO2 and H2S from gas streams. We also have extensive experience and know-how for CO2 enhanced oil recovery and CO2 recovery from flue gas. 

LNG Liquefaction / Feed Gas Pretreatment

CB&I has developed proprietary liquefaction and feed gas pretreatment technologies. We have patented designs for mid-size, floating natural gas liquefaction systems and feed gas pretreatment for the removal of potential freeze components such as benzene, toluene, xylene and other aromatic cyclic compounds.

Nitrogen Rejection / Helium Recovery

CB&I has extensive experience and capabilities in nitrogen rejection from natural gas streams. We have provided the conceptual design and basic engineering for feed rates 25 to 450 MMSCFD.

Modular PSA Recovery

Building on a track record of over 100 Pressure Swing Adsorption (PSA) units since 1969, CB&I is your full-range supplier of adsorption-based gas separation plants for hydrogen, helium and other high-value gases.
