Asab Gas Plants are located next to one of the richest oil fields in the country, 190 km south of the City of Abu Dhabi.
Asab-0 NGL extraction plant has been in operation since its start-up in 1981. It receives the associated gas (capacity 306 MMSCFD, Single Train) coming from the adjacent oil producing company (ADCO). After being compressed, the feed gas is cooled down to -80 deg. C in order to ensure a high NGL recovery. The NGL is pumped to Gasco Ruwais plant, where it is fractionated into C2 (Ethane), C3 (Propane), C4 (Butane) and C5+ (Paraffinic Naphtha ). The residual gas is compressed and sent to the ADNOC gas networks.
Asab-1 started in 2001 to process condensate rich gas from Thammama F/G reservoirs. It encompasses two parallel processing trains, with a total capacity of 826 MMSCFD. Condensate is extracted from the feed-gas at a rate of about 80,000 bpd; after stabilization, and then pumped to TAKREER Ruwais oil refinery at a distance of 215 km. Residual gas is re-injected into the reservoir for pressure maintenance purposes (Gas cycling).
Asab-2 project currently under implementation by GASCO will add gas treatment and NGL extraction units to the existing condensate recovery facilities. It is planned to go on stream in 2010.
Asab-3 project, whose FEED at the final completion stage, encompasses debottlenecking of Asab-0 plant, with additional equipment, to process the forecasted increase in associated gas feed and divert up to 150 MMSCFD of the feed gas to Asab-1&2 for further processing.
