Aromatic Company ATC Reformer and Aromatics Complex, Thailand
During the second half of 2004, the board of the Aromatic Thailand Company (ATC) announced it had given the go ahead on plans to build a reformer and aromatics complex, the Aromatics Complex II Project (AR3). The complex is located in Map Ta Phut, Thailand.
The complex has a capacity of 655,000tpa of paraxylene (PX), 355,000tpa of benzene and 60,000tpa of toluene. The facilities required an investment in the region of $650m.
Construction of the AR3 commenced in 2005 and the facility became fully operational in January 2009. The complex was built to expand production capacity at ATC's Aromatics Complex I.
Configuartion of the Aromatics Complex II project
The complex consists of a reformer section and an aromatic section. Both sections include six process units each. The complex includes a tank farm, flare system and wastewater treatment facility. It has three tanks for storing condensate.
These were built in 2008.
The project required the construction of 15 feedstock and product pipelines which connect the existing facilities with AR3. The pipelines have a diameter of four to eight inches with a total length of 152,350m.
Design and technology provision for the paraxylene unit
During February 2005, UOP was awarded a contract to provide the design and technology for the paraxylene plant.
During October 2005, ATC signed a contract with a consortium comprising of two Korean companies, SK Engineering & Construction (SKEC) and GS Engineering and Construction (GS E&C), to build its aromatics complex. The value of the contract was not disclosed.
Project management services
UK-based Foster Wheeler was awarded a contract to work as the project management contractor on ATC's aromatics complex. The terms of the contract were not disclosed.
Foster Wheeler was responsible for the co-ordination of engineering, procurement, construction and commissioning phases of the project. The contract was awarded in October 2005.
Technology incorporated into the Aromatic Thailand Company's reformer and aromatics facility
Emerson Process Management was chosen to automate the complex. The company installed its PlantWeb digital architecture with FOUNDATION fieldbus technology across the facility. The technology enables plant personnel to monitor operations remotely and alerts them in case of a malfunction.
Contractors involved in the project
SKEC contracted Kie Systems to supply its Moter Operated Valve, Burner Management System and Gayesco-Multi Thermocouple for the complex. Oksan was subcontracted by GS E&C to carry out mechanical and piping work for the project.
TransTel Engineering installed a CCTV system at the complex.
Foster Wheeler subcontracted Christiani & Nielsen to build the pipelines connecting AR3 with the existing facilities of ATC in Map Ta Phut.
Unity Engineering and Consultancy Services provided detailed engineering design and technical services for 14 pipelines under a contract from Christiani & Nielsen.
Background to the Aromatics Complex II project
Completion of AR3 increased ATC's total benzene and paraxylene output to 662,000tpa and 1.12mtpa respectively. Benzene is used by ATC for cyclohexane production, while demand for paraxylene is expected to grow strongly in Asia.
