2000年版「アジア化学工業白書」 各国のソーダ、塩ビ事業概況

中国

 中国のPVC需要は堅調に推移しており,2000年も10%前後の成長が見込まれ,市場規模は400万トンに達する見通しである。この成長を支えているのは,主として純内需であり,パイプ,窓枠などの建築用硬質塩ビの伸びが著しい。他方,総需要の30%を占める製品再輸出のための需要は99年までは米国の好景気に支えられ堅調であったが,2000年上期は前年並みにとどまっている。

 需要増に対応して滄州石化が99年第2四半期に23万トン増設,第3四半期には蘇州華蘇が10万トン新設,錦化集団が8万トン増設,99年末にLG DAGUが5万トン増設,2000年第2四半期には江蘇蝙蝠集団が5万トンの新設をそれぞれ行っている。これにより,PVCの総能力はカーバイド・アセチレン法の150万トンと合わせ310万トンを超えることになった。
 こうしたPVCの新増設があっても堅調な内需をカバーするに至らず,2000年も150万トンを上回る輸入が確実とみられている。

 PVCの需要増に伴い,EDC・VCMの需要も増加しているが,構造的なエチレン不足などにより輸入が急増する傾向にある。VCMは98年から輸入が本格化し,99年は38万トンに達している。アセチレン法の生産を代替するための輸入は減少傾向にあるが,絶対需要の伸びから2000年のVCM輸入は40万トンを突破する見通し。また,EDC輸入も98年は8万トン規模であったが,99年は22万トン,2000年は30万トンを超える見通し。

 今後のPVC新増設は,2000年後半に上海天原集団4万トン新設,斉魯石化5万トン増設,蘇州華蘇3万トン増設,2001年半ばにLG DAGU6万トン増設が予定されている。
 また,上海クロールアルカリ,滄州石化,福州石化などが30万トン規模のVCM・PVCプロジェクトを検討している。

 カ性ソーダの99年内需は,化学繊維・レーヨン,紙パルプ,せっけん洗剤を中心に485万トンであった。輸出は上海クロールアルカリを中心に15万トンが見込まれている。多くの電解メーカーは内陸に立地しており,物理的に輸出用インフラが整っていない。今後の内需の伸びは年率数%の見通し。


中国のPVC産業の特徴

上記の旧式弱小ラインのほとんどはカーバイド・アセチレン法VCMによるものである。

中国政府は環境問題その他からこの設備を順次廃棄するよう指導している。
一部PVC設備は輸入VCMに切り替えるが、地方のPVC設備は廃棄される見込み。

上記記事ではカーバイド・アセチレン法PVCを150万トンとしている。

Shanghai Chlor-Alkali Chemical to form PVC joint venture in Ningxia

Shanghai Chlor-Alkali Chemical (SCAC) plans to form a joint venture with two Chinese companies to build a 100-120 000 tonne/year polyvinyl chloride (PVC) plant in Ningchuan, Ningxia(寧夏) in western China, according to a company source.

The two local partners are Ningxia Ninghe National Chemicals Group Co, a producer of calcium carbide, which will hold a 40% stake, and an unnamed power company, which will hold 30%. SCAC will also own a 30% stake. The new company, which has yet to be formed, is to be called Ningxia West PVC.

The project will use the acetylene-based route. Acetylene, obtained by mixing calcium carbide with water, is used to react with hydrogen chloride to produce vinyl chloride monomer (VCM), which is then used to make PVC.

The investment is estimated at slightly above Rmb900m ($108.7m/Euro92.7m). The project will produce a corresponding amount of caustic soda, chlorine and VCM.

The source said Ningxia was chosen because of its coal reserves and competitive electricity rates, which are one-third of the price charged in Shanghai.

SCAC expects to use mainly local technologies for the project, which is slated to start up in H2 2005.

It was not immediately clear how the project would affect talks between SCAC and Tosoh for a PVC project in China. SCAC has been in talks with Tosoh for a PVC plant outside Shanghai that is set to start up after 2005.

Phase 2 of China's Ningxia PVC project would be started

Shareholders of a polyvinyl chloride (PVC) project in Ningxia, China, plan to pursue a second phase which would boost their total PVC capacity to 500 000 tonne/year.

Shanghai Chlor-Alkali Chemical (SCAC), Ningxia Yinglite Chemical(formerly Ningxia Ninghe National Chemicals Co) and Ningxia Yinglite Power are planning to build a 120 000 tonne/year PVC facility and a 100,000 tonne/year caustic soda plant in Shizuishan(石嘴山), Ningxia, as part of their first phase of the project.

Ninghe was renamed earlier last month because of a 51% stake acquisition by Yinglite Power last year. Yinglite Chemical is now a subsidiary of Yinglite Power. The shareholders have formed a new company, Ningxia West PVC, to operate the planned plant. 

The second phase, estimated to cost Rmb6.4bn ($773.2m/Euro687.7m), is expected to include 380 000 tonne/year of PVC, at least 250 000 tonne/year of caustic soda and a power plant. Startup is targeted for 2008.

A source from the company said it would seek government approval for a proposal on the second phase later this year.

Meanwhile, engineering work has begun on the first phase, which is due to start up in H1 2005. It will employ local technology.

Both phases will be using the acetylene-based routes as Ningxia has coal reserves, from which calcium oxide and coke can be derived to make calcium carbide.

Shanghai Chlor-Alkali Chemical reconsider Caojing's PVC project

Shanghai Chlor-Alkali Chemical (SCAC) may decide against producing polyvinyl chloride (PVC) at its complex in Caojing, Shanghai, China, as originally planned, according to a company source.

The company is considering whether to limit production to either ethylene dichloride (EDC) or vinyl chloride monomer (VCM).

The source said the company was certainly unlikely to produce PVC in Caojing for now and was still deciding whether to produce 300 000 tonne/year of EDC, along with 250 000 tonne/year of caustic soda and 200 000 tonne/year of chlorine at a proposed chloralkali unit in Caojing. The alternative was to develop the chloralkali unit further downstream to produce around 200 000 tonne/year of VCM as well.

If the company drops the VCM and PVC units, the investment cost of the project would be reduced from Rmb3.6bn ($435m/Euro372.9m) to Rmb1.8bn. Startup is scheduled for H2 2005.

SCAC originally wanted to produce 200 000 tonne/year of PVC.

Tianjin Dagu
天津大沽 ) starts work on 200 000 tonne/year PVC

Tianjin Dagu Chemical has started construction work on a 200 000 tonne/year PVC plant in Tanggu, Tianjin, China, said a company source.
The company aims to bring the Rmb815m (US$98.5m) project onstream at the end of 2004.
Tianjin Dagu is part of Tianjin Bohai Chemical Industry which also owns two PVC-producing affiliates - Tianjin Chemical Plant and Tianjin LG Dagu Chemical.

It was told last year that Tianjin Bohai plans to build a 660 000 tonne/year PVC plant in two stages, to boost its total production to more than 1m tonne/year. Tianjin Dagu produces around 280 000 tonne/ year of PVC; Tianjin Chemical Plant owns a 120 000 tonne/year plant; and Tianjin LG Dagu recently expanded its plant to 340 000 tonne/year from 240 000 tonne/year.

The source said plans to add more capacities are not firm. He did not dismiss the possibility of Tianjin Dagu co-operating with LG Chemical on other projects. LG is a partner in Tianjin LG Dagu. The South Korean major is currently evaluating taking a stake in a PVC project in Fujian, China.

The source added that sourcing feedstock for its future PVC plants is one problem hindering its plans from moving ahead. Dow Chemical was supposed to build a cracker in Tianjin, but its plans seem to have stalled.

Tianjin Dagu plans to build ethylene storage tanks to accommodate imported ethylene for its new 200 000 tonne/year PVC plant. It hopes to complete building the tanks by end-2004. The company is expected to use local PVC technology.

The company now produces 140 000 tonne/year of PVC via the calcium carbide route, 40 000 tonne/year based on imported VCM, and the balance 100 000 tonne/year at an integrated chlor-alkali, ethylene dichloride and VCM complex.

China's Qinghai mulling PVC, methanol projects in Geermu

Qinghai Western Chemical is planning a polyvinyl chloride (PVC), magnesium and methanol project in Geermu, Qinghai, western China, a company source said. The province has abundant natural-gas resources.
Geermu, Qinghai=青海省格尓木)

The project has attracted the interest of China International Trust and Investment Corp (Citic), which took a majority 70% stake in Western Chemical in March this year.
The source explained that the company would provide raw materials for the project, and Citic the financial resources. The Chinese government has approved the project.

Western Chemical and Citic plan to
make use of natural gas to make acetylene through partial oxidation. The acetylene will then be used to make vinyl chloride monomer (VCM) and subsequently PVC. Synthetic gas is produced in the process, which will be used to make methanol.

Chlorine would be available from a nearby salt lake, 30-40 km from the project site, which contains mainly magnesium chloride. Western Chemical has the exclusive right to develop the lake.

Construction of the PVC plant is expected to start next year, with the first phase due for completion in 2006 at a cost of Rmb2bn ($241.6m /Euro211m).
In this phase, the plant would produce 45 000 tonne/year of magnesium, 150 000 tonne/year of PVC, and 250 000 tonne/year of methanol.
The second phase, for which no startup date has been set, will produce 75 000 tonne/year of magnesium, 200 000 tonne/ year of PVC, and 250 000 tonne/year of methanol.


The source said a technology licensor for the gas-to-acetylene unit has yet to be selected, but it is likely to be Sinopec. The technology for the rest of the project has not been decided.

There has been increasing interest among Chinese companies in gas-rich provinces to convert gas to acetylene. The two conventional methods of PVC production are: the calcium carbide route, which produces acetylene from the hydrolysis of calcium carbide; and the ethylene route, which produces the intermediates, ethylene dichloride and VCM. The former route, which makes VCM from acetylene, is viewed as less environmental-friendly.

Xinjiang Zhongtai Chemical is also considering using the gas-to-acetylene route to produce PVC in Xinjiang.

A PVC consultant said the feasibility of using the gas-to-acetylene route for PVC production depends very much on the price of gas and electricity. He thinks that gas should be priced below Rmb0.60/std m3 for the project to be competitive with the other PVC-producing routes.

The source from Western Chemical said talks are under way with gas and electricity suppliers. However, he is optimistic that the project will be competitive, as he expects to secure a very good price for gas at around Rmb0.50/std m3 on a long-term contract.

Agreements with the gas and power suppliers will be signed this year.

100 000 T/A PVC Project Launched in Shaanxi 陜西省楡林

According to the news disclosed by Shaanxi Investment Group Corporation, the 100 000 t/a PVC project located in Yulin of North Shaanxi with a total investment of RMB1.15 billion has got the approval of the provincial development planning commission. The construction will start in Mizhi County in Yulin in early August this year.

The project has a capacity of 300 000 t/a PVC and occupies an area of around 66 ha. The capacity of the first phase is
100 000 t/a PVC and a matching 100 000 t/a ion membrane caustic soda unit will also be constructed.

Shaanxi Investment Group proposed the PVC project proposal in December last year on the basis of in-depth market survey. The purpose is to fully use the rich resources in Yulin such as calcium carbide, rock salt and power to develop salt chemical industry and accelerate the construction of North Shaanxi energy and heavy chemical industry base. A project capital of RMB300 million has already been subscribed today.

PVC is a large-volume chemical raw material with the greatest consumption in plastic processing. With the rapid development of the national economy and the policy guide of "replacing wood with plastics" and "replacing steel with plastics", China has become one of the major PVC consumers in the world. The domestic production falls far short of the demand and the product market prospect is therefore extremely bright.

Shenyang to produce 50 kt/yr of paste PVC in two phases

Shenyang (瀋陽) Chemical Co plans to produce 50 000 tonne/year of paste-grade polyvinyl chloride (PVC) in two phases in Shenyang, Liaoning (遼寧省), China, according to a company source.

Discussions are taking place with potential foreign partners for the first phase of 30 000 tonne/year. Shenyang Chemical hopes to select one partner soon so that construction work can start in September or October. Construction would take about one year, the source said.

The company plans to build the plant based on the acetylene route. It also plans to proceed with a second phase of 20 000 tonne/year of paste-grade PVC which would start up in 2005.

The source said the company would buy either vinyl chlordie monomer (VCM) or ethylene dichloride (EDC) and use the feedstock to expand its existing VCM plant to support this phase. It currently uses the acetylene route to produce 45 000 tonne/year of paste-grade PVC.

Singpu considers PVC production

Singpu Chemicals is investigating the possibility of diversifying into the production of PVC from caustic soda, aniline and chlorine in China. Capacity and startup date are unknown, as the project is at a preliminary stage. The company operates in the China Fine Chemical Industry Taixing Park and produces 97,500 tonnes/y caustic soda and 30,000 tonnes/y aniline, despite having a nameplate capacity of 43,000 tonnes/y. The company is undertaking an initial public offering (IPO), from which it hopes to raise S$13.7 M. This will be used to raise caustic soda capacity to 150,000 tonnes/y as well as maximising capacity at the aniline plant.


Singpu Chemicals       http://www.singpu.com

Our Company was incorporated in Singapore on 8 November 1990 as a private company limited by shares under the name of Panasia Investment Pte Ltd. We changed our name to Asiawide Chemicals Pte Ltd on 29 December 1995 and set up Singpu Chemcials Industries (Taixing) Co., Ltd. ("SCI") as our wholly-owned subsidiary in the PRC on 30 December 1995. On 29 July 2002, our Group acquired an 80% interest in Singpu Chemicals Industries (Yancheng) Co., Ltd.("YSC"), a joint venture company operating in the PRC, from our Parent Group. On 18 February 2003, we changed our name to Singpu Chemicals Pte Ltd. In August 2003, we are listed on the Mainboard of the SGX-ST and changed our name to Singpu Chemicals Ltd.

Strategically-located production facilities
Singpu Chemicals' two production plants with a total land area of approximately 313,000 sq m are strategically located in
Taixing(泰興) City and Yancheng (塩城)City in the Jiangsu province(江蘇省).

Jiangsu Province, being one of the most strategic locations for chemical manufacturing and distribution, is the one of the largest producer of aniline and the second largest producer of caustic soda in the PRC.

To further develop Jiangsu province as a hub for the chemical industry, the local provincial government established the China Fine Chemical Industry Taixing Park (previously known as "Taxing Economic Development Area") in 1991. Today, the industrial park has attracted internationally-renowned chemical companies such as Akzo Nobel Chemicals MCA (Taixing) Co., Ltd (a Fortune 500 Company), SNF (China) Flocculant Co., Ltd (a French water treatment agent manufacturer), and Noviant CMC (Taixing) Co., Ltd, with many more coming.

As
the largest Chlor-alkali producer in the industrial park, we are well-placed to be the principal supplier of caustic soda and chlorine to the increasing number of large chemical producers setting up operations in the area.

Recognised as one of the market leaders in the chemical industry in Jiangsu province, we are the only Chlor-alkali producer licensed to operate a chemical jetty along the Yangtze River with a handling capacity of 5,000 tonnes of liquid chemicals, thus enabling optimal operational and cost efficiencies, and reliability in delivery.

Our track record in the PRC gives us a foothold in the rapidly growing PRC economy and affords us an edge over companies who are new entrants to the PRC market.

Singpu plans VCM and aniline units

SINGPU Chemicals submitted a feasibility study to the Chinese government last month on building a 200 000 tonne/year vinyl chloride monomer (VCM) unit and a 45 000 tonne/year aniline unit, and on doubling its caustic-soda production, said Chan Hian Siang, chief executive officer (ceo).

The company told ACN last year that it was conducting an internal feasibility study on diversifying into polyvinyl chloride (PVC) production from caustic soda, aniline and chlorine at its production site in China. Singpu produces 150 000 tonne/year of caustic soda and 45 000 tonne/year of aniline in the China Fine Chemical Industry Taixing Park in Taixing, Jiangsu.

As the investment cost of building a VCM unit and a PVC facility was too high, the company had decided to pursue PVC production later, said the ceo.

The company had also decided to pursue the VCM, aniline and caustic soda project in two phases, said Chan. In the first phase, it would build a 30 000 tonne/year aniline unit and increase its caustic-soda capacity by 100 000 tonne/year. The proposed aniline plant and the new caustic-soda capacity would come onstream by Q3 2005, he said.

In the projects second phase, Singpu will increase the aniline and caustic-soda capacities by 15 000 tonne/year and 50 000 tonne/year, respectively. It would also build the proposed VCM unit in the second phase, which was due onstream in early 2007, said the ceo.

He added that the company would import ethylene to feed the proposed VCM unit.

The VCM unit would cost US$90m to build, said Chan, but he declined to elaborate on the cost of the proposed aniline unit and that of the caustic-soda expansion.

Singpu, which is listed on the Singapore Stock Exchange, currently sells aniline to Yantai Wanhua Polyurethanes, which is planning to build a 160 000 tonne/year methyl di-p-phenylene isocyanate (MDI) unit in Ningbo, Zhejiang. Wanhua now produces 80 000 tonne/year of MDI in Yantai, Shandong.
