Contaminants must be removed from natural gas so that the gas meets the quality standards specified by pipeline transmission and distribution companies, and is safe for industrial applications and home heating and cooking.
However, the presence of carbon dioxide and other contaminants in natural gas, coupled with tight space limitations and extreme environmental conditions, can make natural gas clean-up in many offshore and remote onshore locations difficult. Separex membrane technology was designed specifically to meet these challenges.
Developed in 1979, Separex Membrane Systems remove corrosive acid gas and water from natural gas streams. Housed onshore, or within offshore production ships called Floating Production, Storage and Offloading (FPSO) and Floating Liquefied Natural Gas (FLNG) systems, Separex units are modular, skid-mounted installations containing spiral-wound membrane elements with proprietary compositions.
These membranes remove contaminants to make natural gas safe for transportation, storage and everyday use. In addition to offshore gas processing, Separex Membrane Systems are used for a wide range of onshore treating applications, and removing helium from natural gas streams.
