The FPSO is using the Honeywell UOP Separex membrane system and adsorbents to remove carbon dioxide and water from 5 million standard cubic metres of natural gas per day from the Lula oil field in the Santos Basin off the coast of Brazil.

A second FPSO, still in construction and also using UOP Separex technology, is expected to be commissioned in September 2012.
To date, 130 UOP membrane units have been installed worldwide.
