Wanhua Chemical's 10,000-ton isopropanolamine project: Integration advantages may reshape the IPAM landscape
Thread Content
On March 31, the environmental impact report of Wanhua Chemical’s 10,000 tons/year IPAM (isopropanolamine) project was announced. The project mainly produces monoisopropanolamine (MIPA), diisopropanolamine (DIPA), and triisopropanolamine (TIPA). From the early 500 tons/year test project verification to the current large-scale implementation of 10,000 tons, its "petrochemical-fine chemical" integration strategy is expected to reshape the global isopropanolamine market structure. 1. Product core value 1. Isopropanolamine is an alcoholamine chemical containing amino groups and alcoholic hydroxyl groups. It has both the alkalinity and nucleophilicity of amines and the hydroxyl activity of alcohols. It can participate in various reactions such as neutralization, addition, esterification, and etherification. It is a key intermediate connecting basic chemical industry and high-end applications. Compared with its homologue ethanolamine, it is more environmentally friendly, less toxic, has good oil solubility, and has excellent color and thermal stability. 2. As global environmental protection becomes stricter, developed countries such as Europe, the United States and Japan * * Ethanolamine has been classified as a hazardous substance and its use is restricted. As a low-toxic alternative, isopropanolamine has continued to expand its application scenarios in the fields of surfactants, natural gas desulfurizers, cement additives, pharmaceutical and pesticide intermediates, cosmetic bases and electronic cleaning, and its demand has steadily expanded. 2. Production process and technology sources 1. Domestic isopropanolamine production is mainly based on the propylene oxide method, which is produced by distillation through the reaction of propylene oxide and liquid ammonia. A few companies use the calcium cyanamide method. Core technologies are mainly divided into two categories: international introduction and independent research and development. ； 2. In the early days, domestic enterprises mostly introduced processes from giants such as BASF and Dow, and their core technologies were restricted. ； Hongbaoli and Wanhua Chemical have achieved independent breakthroughs. Hongbaoli has developed a new production process for high-pressure supercritical flow synthesis of isopropanolamine, reaching the world's advanced level and filling a gap in China. ； Wanhua Chemical officially announced the 500 tons/year isopropanolamine (IPAM) industrial test project in April 2023. Through independently developed process technology, it strives to achieve internationally leading product competitiveness, thereby breaking the technology monopoly of multinational companies.
3. Innovative process and integrated model 1. The mainstream process of isopropanolamine generates different types of isopropanolamine by adjusting the feeding ratio of propylene oxide and ammonia. The difficulty lies in the precise separation and purity control of the product mixture. 2. Wanhua completed pilot testing as early as 2023. This 10,000-ton project is a quantitative leap forward in pilot testing results. More importantly, Wanhua has an annual production capacity of over 1 million tons of propylene oxide. This "propylene oxide/ethylene oxide-polyether polyol-isopropylamine" integrated industrial chain advantage enables Wanhua to achieve self-sufficiency in core raw materials, greatly avoiding the risk of raw material price fluctuations and reducing costs to the lowest level in the industry. 4. Current market supply and demand and import volume 1. Domestic isopropanolamine presents a "structural supply and demand imbalance." Currently, there are only a dozen companies in the world that can produce isopropanolamine, and the market has long been dominated by multinational giants such as BASF of Germany and Dow Chemical of the United States. Domestic production capacity is relatively concentrated. Hongbaoli has a 40,000-ton/year isopropanolamine production unit and a 50,000-ton/year diethanol monoisopropanolamine unit. The total designed production capacity is 90,000 tons/year, accounting for more than 50% of the domestic market. ； Damin Co., Ltd. owns the "propylene oxide-isopropanolamine-propylenediamine" industrial chain and can produce 40,000 tons of isopropanolamine annually. 2. China’s isopropanolamine market has achieved significant growth in the past decade, especially in industries such as personal care, household cleaning and green building materials. However, high-end products are still highly dependent on imports. Imported products occupy high value-added fields such as electronics and high-end medicine due to their high purity and excellent stability.
5. Break the monopoly and reshape the pattern 1. The entry threshold for the isopropanolamine industry is extremely high, with core technology, raw materials and environmental protection forming barriers. The entry of Wanhua Chemical will undoubtedly have a huge impact on the existing market structure. 2. On the one hand, Wanhua’s product competitiveness has reached international levels by virtue of its independently developed process technology, which will break the technology monopoly of multinational companies. ； On the other hand, Wanhua's PO production capacity of over one million tons corresponds to a very high potential production capacity of isopropanolamine. Its large-scale production will not only intensify competition in the domestic market, but may also rewrite global trade flows with its cost advantage, allowing China to occupy a more favorable position in the global isopropanolamine supply chain. 6. Industry development trends In the future, the isopropanolamine industry will develop along three main lines: 1. High-end and domestic substitution: With the technological breakthroughs of domestic enterprises, the localization rate of high-end products will continue to increase, gradually replacing dependence on imports. 2. Environmental protection drive: Stricter environmental protection policies will accelerate the withdrawal of backward technologies, and the replacement of ethanolamine by isopropanolamine will also accelerate. At the same time, its application expansion in emerging fields such as agriculture and new energy support will bring new increments 3. Integration: The layout of the entire industry chain will become the key for enterprises to reduce costs and increase efficiency, and industry concentration will further increase. The advancement of Wanhua's 10,000-ton project marks that the domestic isopropanolamine industry has entered a new stage of large-scale and high-quality development, and will promote the entire industry to leapfrog from "mid- and low-end supply" to "high-end independence."
