Map Ta Phut Olefins Company (MOC), Thailand

Early in 2008 the Map Ta Phut Olefins Company (MOC) began construction on a new integrated plant.

During February the company laid the foundation stone for the integrated olefins and polyolefins production plants built at Map Ta Phut, Thailand.

The complex produces 900,000tpa of ethylene and 800,000tpa of propylene. Downstream production plants include 400,000tpa of high density polyethylene (hdPE) and 400,000tpa of polypropylene. The plant commenced operations in March 2010.

Naphtha cracking units

Samsung Engineering was awarded a contract to supply MOC's cracking units.

The contract, which included construction of an olefin recovery unit and olefin convergence unit, was valued at $347.4m.

Cracking furnaces

"The complex produces 900,000tpa of ethylene and 800,000tpa of propylene."

At the end of 2006, Technip announced it had been awarded a contract for the construction of the furnace section of the steam cracker.

The cracker produces 900,000tpa of ethylene and 800,000tpa of propylene.

The lump sum turnkey contract covered basic and detailed engineering, procurement, supply of materials, construction, pre-commissioning and training of personnel.

The furnace is based on Technip’s proprietary GK6 cracking furnace technology which allows a furnace to run on a range of feed stocks from naphtha to heavy oil.


Sino Thai Engineering & Construction Public Company provided pipe work for the cracking furnace.

Tank farm unit

Thailand's Thai Rotary Engineering Company supplied tank farm units for the Map Ta Phut Olefins' chemical complex.

The company built a process plant off-site facility which involved the construction of 15 spherical and atmospheric tanks, which were used for the storage and handling of various chemical products. The contract covered engineering and construction, and was valued at $535m.

Condenser systems

US-based Graham Corporation supplied Map Ta Phut Olefins with two surface condensers which were installed in the cracker.

Control system

During the second half of 2007, Yokogawa Electrical Corporation announced it had received a contract to supply control systems, field sensors and other devices for the Map Ta Phut Olefins' petrochemical complex.

"The cracker builds on Dow's long-standing business relationship with SCC."

Yokogawa participated as the main automation contractor (MAC) and worked alongside the engineering procurement and construction contractor. The company said this was the first time that it had won a MAC contract in Thailand.

Under the contract Yokogawa delivered a CENTUM CS 3000 integrated production control system and ProSafe-RS safety instrument system as process gas chromatographs, and field sensors such as pressure transmitters and flow meters.


During 2006 Dow Chemical announced that it planned to move ahead and develop a joint venture liquids cracker in Thailand.

The company said the facility would provide propylene and other building blocks to help drive the growth of its performance business across Asia Pacific.

The cracker builds on Dow's long-standing business relationship with SCC, which began in 1987.
