Fatty alcohol enterprises have pointed out that large-scale production is the only way out for the “fattening” experts. The scale of the equipment should be expanded to 30,000 to 50,000 tons/year.

Although the summer season is hard to resist, the expansion site of fatty alcohol in Wuhan Sifangxing Chemical Co., Ltd., located in Wuhan Chemical Development Zone, is still in full swing. In recent years, due to the small production capacity that cannot meet the market demand, the company's 12 million yuan investment in the old equipment transformation project of fatty alcohol is in full swing, after the completion of the project transformation, its production capacity will be expanded from 4,000 tons / year to 15,000 tons / year. At the same time, Jiangsu Yonglin Grease Chemical Co., Ltd. plans to invest 60 million yuan to build a 20,000 tons/year high-grade fatty alcohol project; Xinjiang Hutubi County plans to use 35,000 tons/year of cottonseed oil to invest 80 million yuan in construction. 30,000 tons/year natural fatty alcohol project; Liaoyang City plans to invest 170 million yuan to jointly develop 40,000 tons/year natural fatty alcohol project; Jiangsu Sasol Yihai (Lianyungang) Alcohol Industry Co., Ltd. plans to build 60,000 tons/year of fat Alcohol project.

In view of the domestic trend of fat alcohol production enterprises to set a small “fattening” trend, industry experts pointed out that large-scale production is the way out for many domestic manufacturers of fatty alcohols, and domestic production companies should expand the scale of equipment to 30,000-50,000 tons. Year is appropriate. Experts from the China Petroleum and Chemical Planning Institute affirmed the “fattening” measures of domestic fatty alcohol companies. According to experts, at present, the world's production of fatty alcohols continues to expand. As the international oil prices have remained high in recent years, the development of the synthetic fatty alcohol industry using olefins as raw materials has stagnated, and the development of natural fatty alcohols has gained momentum. According to incomplete statistics, the proportion of global natural fatty alcohols in the total amount of detergents has risen from 40% in 1988 to over 50% currently. China has successively built two large-scale synthetic fatty alcohol plants of Jilin Chemical's 100,000 tons/year and Fushun's 150,000 tons/year through the introduction and self-designed period during the “Eighth Five-Year Plan” and “Nineth Five-Year Plan” period. Currently, it has ceased production due to shortage of raw materials and olefins. , Natural fatty alcohol companies re-assumed the protagonist of fatty alcohol supply. However, at present, the domestic natural fatty alcohol industry has the following problems: First, the scale of the device is small. Currently, there are less than three manufacturers with a production scale of 10,000 tons/year or more, and most of them are devices with an annual output of less than 10,000 tons. Due to its small scale and high production costs, the products lack market competitiveness. Second, the total amount of fatty alcohol is insufficient. The actual domestic production is less than 100,000 tons/year, and many application markets have not been developed. Experts suggest that: According to the characteristics of fatty alcohol production and supporting raw materials - the scale of hydrogen production requirements, domestic production companies should expand the scale of the device to 30,000 to 50,000 tons / year is appropriate. At the same time, the hydrogen source of fertilizers and caustic soda companies can be used for the production of fatty alcohol companies. For the built-up synthetic fatty alcohol enterprises, overall planning should be well done to replace petroleum fuels through development and free up a part of olefinic raw materials for the production of synthetic fatty alcohols.

Fatty alcohols are important raw materials for the production of surfactants, textile auxiliaries, printing and dyeing auxiliaries, agricultural emulsifiers, shampoos, bath liquids, laundry detergents and other products. With the improvement of people’s living standards, the demand for fatty alcohols is rapidly increasing. With the increase, the development and application of fatty alcohols and derivatives have broad prospects. For example, in the field of surfactants, foreign industrial surfactants account for 60% of the total amount of surfactants, while China accounts for only about 30%. At present, the industrial application of fatty alcohol products is still relatively narrow in China, and many industrial applications have not yet been developed. In energy development and energy-saving technologies such as oil extraction and tertiary oil recovery, oil or coal and water, food, paper, textile, machinery and construction In areas such as materials, there is huge market potential.
