 Gas was dehydrated in a counter-current glycol dehydrator operating at 1000 kPa, the gas stream could also be passed through a zinc oxide unit to remove sulphur compounds.A turbo-expander/re-compressor unit and a Joule-Thomson valve allowed the gas to expand and chill (from 7550 kPa at 11 °C to 3931 kPa at –13 °C) to extract natural gas liquids (NGL).These, together with condensate from the compressor scrubbers, was co-mingled with the export oil stream.
