Asab NGL extraction plant has been in operation since 1981. It receives the associated gas (capacity 300 MMSCFD, single train) coming from ADCO.
Asab was the first plant in this region to be equipped with a turbo-expander in order to ensure a high NGL recovery. The NGL is pumped to GASCO Ruwais plant for further treatment and the residual gas is compressed and sent to the network.
In 2001, Asab started to process condensate-rich gas from Thammama F/G reservoirs, with a total capacity of 870 MMSCFD. Condensate extracted from the feed gas at a rate of about 95,000 bpd is sent to TAKREER oil refinery in Ruwais. Residual gas is re-injected into the reservoir.
Other facilities under implementation add NGL extraction unit to the existing condensate recovery facilities. Furthermore, acid gases recovered from the associated sweetening unit will be recompressed and re-injected into the reservoir. Further developments include debottlenecking to process the anticipated increase in associated gas feed.
