Tacaamol Aromatics Project, Al Gharbia, Abu Dhabi, United Arab Emirates
Abu Dhabi National Chemicals Company (ChemaWEyaat) is constructing a major chemicals hub in the Taweelah district of Al Gharbia in Abu Dhabi, UAE. The site will include aromatics, olefins, propylene, ethylene and nitrogen chemicals complexes.
It will be developed in three phases, against the previous plan to develop it entirely in a single phase. It would have required an investment of about $20-25bn. The project has been scaled down and is planned to be built in phases to make it more feasible.
ChemaWEyaat was established in November 2008. The stakeholders of the company are the Abu Dhabi Investment Council - 40%, International Petroleum Investment Company (IPIC) - 40% and Abu Dhabi National Oil Company (ADNOC) - 20%.
Tacaamol Aromatics Project site development
The first phase includes the construction of the aromatics complex, called the Tacaamol Aromatics Project (TAP) and Madeenat ChemaWEyaat Al Gharbia (MCAG) site development.
It is estimated that the project will cost about $11-20bn. It is expected to come on stream in 2016. The first phase will produce about 10mtpa of chemical products.
Design of the Al Gharbia-based chemicals hub
The aluminium industry in the Middle East is becoming more and more important to the economy of the region.
The Abu Dhabi Government has allocated about 70 square kilometres to ChemaWEyaat in Al Gharbia for establishing the chemical complexes.
The chemical hub will be built on the Khalifa Port and Industrial Zone premises in the eastern part of Abu Dhabi. The site will have about 12 chemical projects. The entire site will be named Madeenat ChemaWEyaat Al Gharbia.
The MCAG project will support TAP with the necessary infrastructure and utilities. The master plan of the site envisages construction of a sea water intake and outlet pipelines, a sea port with jetty and loading berth for exports, a storage terminal export tank farm and associated infrastructure.
The Madeenat ChemaWEyaat Al Gharbia is also close to the Ruwais Industrial Complex, easing the availability of feedstock. Ruwais is also home to various chemical complexes including the Takreer refinery, GASCO and Borouge polymers complex.
TAP and polyethylene complex details
The TAP complex will be developed with one of the world's largest catalytic reformers, aimed to meet the demand for downstream chemicals. It will have a capacity to process about 70,000 barrels of naphtha each day.
The aromatics complex will produce benzene, toluene, paraxylene, orthoxylene and meta-xylene from the integrated BTX units. It will also produce cumene, glycols and phenol and export LPG and light naphtha.
The Tacaamol project will include construction of two polyethylene plants. Both of these will have a capacity to produce about one million tons per annum.
Feedstock supplied by ADNOC
Abu Dhabi National Oil Company (ADNOC) will supply the necessary feedstock from its Takreer Ruwais Refinery. ADNOC will supply about three million tons of heavy and medium naphtha feedstock per annum for the complex through pipelines.
The other feedstock such as nitrogen, steam and air will be shared between the TAP and MCAG.
Technologies installed at the chemicals hub
The Tacaamol Aromatics Project will be installed with Borstar technology from Borealis and Advanced Sclairtech Technology (AST) from Nova Chemicals, acquired by IPIC in 2009. Other technology suppliers will include LyondellBasell and Asahi Kasei.
Contractors chosen by ChemaWEyaat
ChemaWEyaat awarded the project management consultancy (PMC) contract for the TAP to WorleyParsons, in April 2011. However, the company withdrew from the project.
In April 2012, Foster Wheeler, a subsidiary of Global Engineering and Construction, was contracted to provide PMC services during the front-end design (FEED) phase of the aromatics complex (stage one) at the site.
The company also has an option to offer its services during the construction phase.
ChemaWEyaat selected Halcrow Group UK to design the master plan for the MCAG chemicals industrial city, in December 2010. The company was chosen among other bidders including Aecom, JURONG Consultants, KEO International Consultants and Bechtel.
Neste Jacobs from Finland is conducting the FEED for the first phase.
