SCC targets petrochemical sector
Investments worth US$1.5bn planned

Siam Cement Plc, the country's largest industrial conglomerate, said yesterday that it was investing up to US$1.5 billion to build up its assets in the petrochemical sector. The company announced a $1.1-billion investment in a joint venture with US-based Dow Chemical to build a new naphtha cracker in Rayong. The plant is expected to have a production capacity of 1.7 million tonnes of olefins, consisting of 900,000 tonnes of ethylene and 800,000 tonnes of propylene.

The new investments come as SCC yesterday reported a 30% decline in net profits in the third quarter from last year due to the slowing economy and higher fuel costs.

The construction by the new joint venture,
67% held by SCC, is expected to begin in early 2006. SCC executives said the new investment would help reduce its feedstock costs and stabilise supplies.

``We are hopeful that the bidding process will begin next year. The plant is scheduled to be operational in 2010,'' said Kan Trakulhoon, the president-elect of SCC.

He added that another $400 million would be invested in the development of a downstream facility utilising olefins output with a production capacity of about
700,000 tons per year. This too would likely start operations in 2010.

Siam Cement, with nearly 100 subsidiaries and with more than 40 billion baht in free cash flow annually, will finance the investment through internal cash flows.

``The fact that we are investing shows that we believe in our capability to be able to compete on a global scale in the petrochemical business and in the future there maybe investments in other businesses as well,'' said outgoing SCC president Chumpol NaLamlieng.

Siam Cement currently has a naphtha cracker with capacity of 1.2 million tonnes per year as well as downstream joint-venture projects with Dow Chemical, Mitsui Chemicals and Mitsubishi Rayon of Japan. The group also has minority stakes in downstream petrochemical projects in Indonesia and Iran.

SCC executives also said that the company's board had approved an investment of 1.09 billion baht in a co-generation plant producing water vapour and electricity for its 99%-owned unit Siam Kraft Industry. The plant will have a generating capacity of 25 megawatts and a steam capacity of 130 tonnes per hour, for use in the production of kraft liner, a material used in packaging.

Analysts said that SCC's plan to invest was a good move and although the market expected it, the sheer size was positive for future growth.

``I view the big story to be the $1.5-billion investment. It's good for the firm in the long run and with a strong partner such as Dow, it is even better. What I am concerned about is whether the chemical cycle will be in a downtrend or uptrend when the plant is completed in 2010,'' said Jiraporn Bumrungchatudom, sector analyst at Phatra Securities.

Mr Kan said that despite the added investments, SCC was on track to pay a dividend for the year matching 2004's 15-baht per share payment. The company paid an interim dividend of 7.50 baht for its first-half performance in August.

SCC yesterday announced a third quarter profit of 8.42 billion baht, down 30% from the year before due to rising fuel costs and the slowing economy.

Third-quarter profits were down 3.5% from the second quarter, with petrochemical margins lower on the back of higher feedstock prices. Sales revenue rose 8% from the same period last year to 56.59 billion baht.

For the nine months ending on Sept 30, SCC reported a net profit of 27.13 billion baht against 27.09 billion baht in the same period in 2004. Sales increased by 19% to 168.23 billion baht.

``The results are not so bad as the market had expected much lower earnings. The slowdown in the economy and the higher fuel and feedstock prices have had an impact on the company,'' said Sukit Udomsirikul, an analyst at Capital Nomura Securities Plc. The market had expected SCC to report net profits of around 7 to 7.5 billion baht.

Shares of SCC closed yesterday on the Stock Exchange of Thailand at 220 baht, up four baht, in trade worth 258.16 million baht. Over the past 52 weeks the shares have traded in a range between 214 and 272 baht.

Thai Siam Cement, Dow Chem to bring naphtha cracker on line 2010

Thailand's Siam Cement Group (SCC) and Dow Chemical have inked a Letter of Intent for a naphtha cracker in Map Ta Phut, Thailand, slated to begin commercial operation in 2010, SCC said in a statement. The cracker would use olefins conversion technology, which is able to generate about 75% more propylene than conventional naphtha crackers. The plant would have the capacity to produce 900,000 mt/yr of ethylene and 800,000 mt/yr of propylene.
SCC would hold a 67% stake in the $1.1-bil cracker, and invest a further $400-mil in polyethylene and polypropylene plants which would draw monomer feeds from the cracker. The derivative plants would comprise a 300,000 mt/yr HDPE plant and a 400,000 mt/yr PP plant. They are also scheduled for completion in 2010, and would specialize in non-commodity grades, SCC said.
Apart from naphtha, the cracker would also have the flexibility to use condensate and LPG as raw materials. Its feedstocks are to be sourced locally and imported.
The cracker would be SCC's second in Thailand. SCC has a stake in Rayong Olefins, which has the capacity to produce 800,000 mt/yr of ethylene in Map Ta Phut. SCC and Dow have five other petrochemical alliances in Thailand -- Siam Polyethylene, Siam Polystyrene, Siam Styrene Monomer, Siam Synthetic Latex and Pacific Plastics. These aside, SCC also has other petrochemical subsidiaries which produce polyolefins, PET, PVC, polystyrene and methyl methacrylate.

Dow Advances Strategy in Asia Pacific
Asset Light Investment to Spur Performance Business Growth

The Dow Chemical Company (Dow) announced today that it plans to move ahead with a joint venture liquids cracker in Thailand; an asset light project in a key emerging geography that will provide propylene and other building blocks to help drive the growth of the Company's Performance businesses across Asia Pacific. The new facility will be developed jointly with The Siam Cement Public Company Limited (SCC).

A number of down-stream facilities will be developed by Dow in conjunction with the new development. Among those under consideration are a hydrogen peroxide to propylene oxide (HPPO) plant - technology developed by the Company in collaboration with BASF - and a range of PO derivatives. PO is used to produce propylene glycol, polyurethanes and glycol ethers.  The new cracker will also allow for the expansion of the existing higher alpha olefins polyethylene joint venture facility, which would produce specialty polyolefin products using Dow's state-of-the-art process and catalyst technology.

Importantly, the proximity of the new facility to the existing Dow-SCC complex at Map Ta Phut in Rayong province will enable existing assets, capabilities and infrastructure to be leveraged, creating a source of advantaged raw materials for downstream derivatives businesses.

"This project supports Dow's strategic agenda on several fronts," said Dow chairman and chief executive officer, Andrew Liveris. "It strengthens the Company's presence in Asia Pacific; it provides a competitive platform on which to develop a range of higher margin Performance business opportunities; and it is another example of our asset-light investment approach, through which we will grow the Basics businesses in joint ventures with strategic partners like SCC."

The cracker, which is expected to commence operations in 2010, builds on Dow's long-standing successful business relationship with SCC and is the latest in a series of joint venture projects between one of the world's largest chemical companies and Thailand's leading manufacturing company. The two companies signed their first joint venture agreement in 1987, and have since formed a total of five joint venture companies, producing polyols, synthetic latex, polystyrene, styrene monomer and polyethylene at the Map Ta Phut site. The SCC-Dow Group of companies has also invested in the ethylene cracker operated by Siam Cement at the site.

The joint ventures planned for Asia are typical of Dow's
"asset-light" approach, which works by offering a combination of intellectual property and money in exchange for a share in a world-scale production facility.

Heres how we are implementing our strategy . on the Basics side, we are pursuing what we call our asset lightapproach investing in conventional joint ventures like those in Kuwait and Oman, for example or, less conventional ones, like MEGlobal and Equipolymers, where we sold our assets into joint ventures.

We benefit from our asset light approach in four important ways.
Access to low-cost feedstocks;
The local expertise of our partners;
Lower capital intensity; and
Less risk.

But in pursuing our asset-light strategy, we will not abandon one of the great competitive advantages of our company: site and product integration, which supports our low-cost position in both our Basics and Performance businesses.

SCG-Dow Group Breaks Ground on Propylene Oxide Plant in Thailand

The Dow Chemical Company (Dow) announced that the SCG-Dow Group, a joint venture between Dow and The Siam Cement Group (SCG), has broken ground on a propylene oxide (PO) facility in Thailand. The world-scale plant, located within the Asia Industrial Estates (AIE) site near Map Ta Phut, will have a name plate capacity of 390 kilotons per annum (KTA) of PO via the innovative hydrogen peroxide to propylene oxide (HPPO) technology jointly developed by Dow and BASF. The PO plant, which will also include propylene glycol (PG) manufacturing, is expected to come online in 2011.

In July 2007, Dow and Solvay S.A. (Solvay) announced the formation of a joint venture to build a new hydrogen peroxide (HP) plant, which will serve as a raw material source for the new PO plant. Located within the AIE site, the new HP plant will be the largest in the world with a name plate capacity of more than 330 kilotons per annum (KTA) of HP at 100 percent concentration, according to the company. The HP will be produced using Solvay's proprietary, high-yield HP technology and supply both the PO plant and Solvay's regional subsidiary, Peroxythai Ltd., which will use the additional product to meet growing customer demand. Operations for the HP plant are scheduled to begin prior to the start up of the PO plant.
"With an economy that continues to grow at double digit rates, Asia Pacific is an attractive location for Dow," said Pat Dawson, president of Dow Polyurethanes. "These plants represent a significant strategic investment by Dow in Thailand for the long-term. Moreover, they will support the continued growth of Dow's performance businesses, such as Polyurethanes, by ensuring that customers who rely on us for materials will be better equipped to compete in their local markets. Together, with BASF, Solvay and SCG, we continue to create sustainable solutions for the production of PO that deliver greater energy efficiency, a reduced physical footprint, and improved environmental performance while also providing attractive economics."
Feedstock for the PO plant will come from the SCG-Dow joint-venture liquids cracker at Map Ta Phut, scheduled for completion in 2010. Several facilities within the AIE site, including the new PO plant, are also expected to be operated through joint venture agreements between Dow and SCG.


Established in 1989, PeroxyThai is a leading producer and supplier of peroxygen chemicals with manufacturing facilities at Rayong and a head office in Bangkok. The company produces hydrogen peroxide for use mainly in the pulp and paper industry with export sales of 40 percent and in-country sales of 60 percent, producing more than 20,000 tons/year.

PeroxyThai is a division of Solvay Group, a global chemical and pharmaceutical company with headquarters in Brussels. It employs some 30,000 people in 50 countries. In 2005 its consolidated sales were EUR 8.6 billion generated by its three activity sectors: chemicals, plastics and pharmaceuticals.
