The additional gas produced was previously re-injected into the Bahrain Field. Therefore, Tawseah was engaged in the construction of a new gas processing facility adjacent to the existing facilities of Banagas and Tawseah, along with associated storage units and other facilities.
The new gas processing facility has a nominal processing nameplate capacity of 350 mmscfd. It is designed to receive the additional associated gas & refinery off-gas and recover propane, butane and naphtha, which will be exported using vessels via the Sitra port. The project also included the construction of additional storage tanks, including a refrigeration train at the Sitra storage area, the construction of new pipelines between the gas processing facility and the Sitra storage area, as well as the installation of a new pipeline to transport the refinery off-gas from the existing refinery off-gas pipeline, which is also compressed along with the associated gas at the Tatweer Petroleum compressor station. The gas is then finally sent to a new gas processing facility via a new pipeline or gas gathering header. The project will also witness the construction of a 66 kilovolt electric substation adjacent to the existing Central Gas Plant.
