Each of the three main units of the complex will be comparatively large. The ethane recovery unit will have capacity of 1 million tonnes a year (t/y), the ethane cracker will have capacity of 810,000 t/y and the methanol unit will have capacity of 2.6 million t/y. The plants will use natural gas feedstock sourced from the South Pars phases 6-8. A new gas processing plant is being built by the consortium developing phases 6-8 to handle higher-than-expected production rates (MEED 4:2:05).

The scope of works on the BPC project comprises basic and detailed engineering, licence provision, supply of equipment and materials, construction, erection, pre-commissioning and commissioning, start-up, performance testing, training and financing. The new complex is to be situated at phase 2 of the Special Petrochemical Economic Zone in Assaluyeh. The first phase is located at Bandar Imam. The NPC utility complex Mobin 2, still to be built, will provide power and water for the complex.
