Project Outline
The 4th Aromatics Plant is the world’s largest petrochemical aromatics
producing complex. The Oil Ministry and the National Petrochemical Company (NPC)
of Iran awarded this project to a joint venture between Jahan Pars, Kayson and
Tehran Jonoob companies.
The project employed over 2,500 workers and nearly 250 site staff, mostly
engineers and technicians, making it one of the largest petrochemical projects
carried out by a private sector company in Iran.
With a total annual capacity of 1.28 million tonnes, the plant produces
750,000 tonnes of paraxylene, 430,000 tonnes of benzene and 100,000 tonnes of
orthoxylene per year as its main products. Pentane cut, liquefied gas, light
hydrocarbons, heavy aromatics and raffinate are considered as byproducts of this
plant and 3.19 million tonnes of them are yearly produced. The annual feedstocks
of the plant are supplied by the liquefied gases of first, second and third
phases of South Pas Gas Field which are 4.5 million tonnes as well as 270,000
tonnes of benzene pyrolysis which are provided by Jam Petrochemical Company, the
implementer of the 10th Olefin project.
Scope of Work
The project involved civil and structural works, installation of mechanical
and electrical equipment, instrumentation, above and underground cabling and
piping. An important feature of the project was the contractor’s commitment to
operate a quality management system based on ISO 9001 standards, using advanced
techniques of project control and putting in place effective occupational
health, safety & environmental management systems.
