Although the financial crisis has passed, the Japanese petrochemical industry is currently facing challenges such as fierce competition in the international market and shrinking domestic demand. To this end, large-scale enterprises use their own capital and technological advantages, adopting the integration of traditional cracking industries, vigorously developing high-value-added petrochemical products, increasing external investment, etc., to promote industrial restructuring and improve competitiveness.
The ethylene industry has stepped up consolidation In the first half of the year, the ethylene industry in Japan has achieved impressive results. However, with the successive launch of large-scale petrochemical projects in the Middle East, many old ethylene crackers in Japan cannot compete with new large-scale ethylene plants with strong raw materials and domestic demand in the Middle East and China. . Since the second half of this year, due to the lack of improvement in market demand at home and abroad, and the continued strength of the yen, Japan’s petrochemical industry has been slow to recover and the products are facing excessive pressure. According to the senior consultant of the chemical industry of Accenture Japan Consulting Co., Ltd., it is estimated that due to lack of competitiveness, in the next 5-6 years, there will be 3-5 sets of uncompetitive crackers in Japan that will be forced to close. The total annual ethylene production capacity will reach 1.5 million. 2 million tons.
As the market space has been severely squeezed and competition has become increasingly fierce, the integration plan for Japan's petrochemical companies that has been brewing for several years has finally begun to implement. Mitsubishi Chemical Corporation and Asahi Kasei Corporation, the two largest chemical companies in Japan, announced on April 1st, 2011 that they will begin to merge their cracking operations in Mizushima, Japan. Mitsubishi Chemical also said that as the demand for ethylene in Japan continues to decline, the cracking business of both companies will reduce their production capacity after the merger operation and will eventually concentrate on one set of equipment. The two companies currently have 500,000 tons/year of ethylene production capacity in Shuidao each built in the 1960s.
On October 1st this year, Mitsui Chemicals and Idemitsu Kosan Co., Ltd., which is located in Chiba, Japan, split the business into a joint venture company called Chiba Chemical Manufacturing Co., Ltd., which includes Mitsui Chemicals' local capacity of 553,000 tons of ethylene per year. Idemitsu Kosan’s local production capacity of 374,000 tons/year of ethylene. The two companies stated that only through this type of cooperation can the competitiveness be enhanced and not eliminated by the market. The two parties plan to expand the business combination approach to the fields of specialty chemicals, polymers and chemical intermediates based on the success of the merger of crackers.
Analysts said that in the future, Japan may further integrate the refining and petrochemical businesses in Kashima, Osaka, and Kyushu, and gradually reduce the production of polyethylene, ethylene glycol, and styrene, and avoid similar production with ethane in the Middle East. The front of the product is confronted and the focus will be on aromatics and vinyl functional chemicals made from propylene.
Aiming at the downstream business In response to the current market environment, Japanese petrochemical companies no longer regard the traditional petrochemical industry as the main business of profit, but give full play to the technological and market advantages of high-tech products and occupy the high-end chemical market.
Mitsui Chemicals, Mitsubishi Chemicals, and Sumitomo Chemical, three major petrochemical companies in Japan, have taken the extension of the industrial chain and the development of their downstream businesses as the focus of their transformation. They have improved the research and development and production capabilities of petrochemical companies in the fields of specialty chemicals, polymers, and key intermediates, and actively developed functions. Resins, high performance films, fine chemicals, pharmaceuticals, and agrochemicals are differentiated products.
Mitsubishi Chemical said it will focus on lithium battery materials and light-emitting diodes. Sumitomo Chemical is also seeking opportunities for restructuring acquisitions in the fields of medicine and pesticides, and plans to produce organic light-emitting diode panels for large-screen TVs. Asahi Kasei Group plans to focus on the development of water treatment systems and high-end healthcare services.
As Japan's automotive and electronics industries have global leading advantages, Japanese petrochemical companies are aiming for a huge market for related materials. In the automotive field, polypropylene is the most used chemical product. Currently, Mitsui Chemicals, Mitsubishi Chemicals, and Sumitomo Chemical have provided polypropylene products to global automakers. At the same time, they have excellent heat resistance, low cost, and can reduce noise and vibration. Plastics, rubber and fiber products with properties such as alternatives to metal materials are generally preferred; in the field of new energy vehicles, lithium-ion battery materials such as electrodes and separators and related parts and components are also the focus of major chemical companies to seize the high ground in the future market; in the field of optoelectronics , LED materials and new circuit board materials have become the core business of Japan Petrochemical Corporation.
Increasing investment in foreign markets At the same time as adjusting domestic industrial structure, Japanese petrochemical producers have also turned their sights on overseas markets, adopted joint ventures with local petrochemical companies, direct investment, mergers and acquisitions, etc., making full use of local resources, markets, and other advantages to expand their own production capacity. .
The Rabig Oil Company, a joint venture between Sumitomo Chemical and Saudi Aramco, is one of the world's largest petrochemical projects. Due to its large scale, the expansion project has been postponed. The company’s 900,000-ton/year polyethylene and 700,000-ton/year polypropylene production unit is expected to start making profits in fiscal year 2010. The feasibility study for the second phase of the production of phenols, nylon resins and acrylics is expected to be held this year. Completed in the fourth quarter. In addition, Sumitomo's synthetic resin company, which is investing in Singapore, will build a solution of SBR and ethylene vinyl acetate copolymer units, which will be launched before the end of the year.
Mitsubishi Chemical also followed. On March 26, 2010, Mitsubishi and China Sinopec formed a joint venture to establish Sinopec Mitsubishi Chemical Polycarbonate (Beijing) Co., Ltd., and plans to invest 2.2 billion yuan to produce chemical products such as polycarbonate and bisphenol A. In Saudi Arabia, Mitsubishi Group has already conducted cooperation with Saudi Basic Industries Corporation and plans to further cooperate in the production of methyl methacrylate and other chemical products. Mitsui Chemicals plans to focus on the development of the aromatics business. It is currently preparing to further strengthen its cooperation with Sinopec on products such as bisphenol A and phenol. It will also consider participating in the development of the Kosan refinery project in Vietnam. It also plans to expand its phenol and poly- Propylene production base. Asahi Kasei also expands its core business such as acrylonitrile and synthetic rubber materials globally. Thailand's joint venture acrylonitrile production project is expected to start production in 2011. In addition, it also plans to invest in a new solution of SBR production facilities in the Middle East and Singapore.
