Protect And Enhance Our Furfural, Furfuryl Alcohol Industry Competitiveness
[ad_1]
At present, China furfural total capacity of about 30 million tons / year, furfuryl alcohol production capacity of about 20 million ton / year, distributed more than 200 manufacturing enterprises in the past more than half of production for export. Developed countries, production declines, gradually withdraw from furfural, furfuryl alcohol and its products markets, the production center of gravity has been transferred to developing countries. China in terms of productivity, both output and export volume ranking first in the world to become furfural, furfuryl alcohol and its largest producer of processed products.
1, uses a wide range
Furfural furfuryl alcohol is mainly used for production of another important use is the production of tetrahydrofuran. Penn United States, some 2 million mt / year of furfural production of tetrahydrofuran unit, due to competitiveness discontinued in 2001, China’s Jilin Qianguo refinery has been the introduction of the technology, plans start construction this year 20 thousand tons / year plant THF . Lubricating oil refining process of furfural used as a solvent, selectively extracted oil will no longer need the aromatics and olefins such as unsaturated hydrocarbon component, leaving only the saturated aliphatic hydrocarbons and alicyclic hydrocarbons, and reduced lubricant sulfur and carbon residue, after removal of impurities to improve the lubricating oil viscosity, color, resistance to oxidation and thermal stability.
At present, China still use most of the oil refining unit of furfural as solvent. In addition, furfural also be used as purified from crude anthracene anthracene oil solvent, rosin decolorizing solvent. In addition, the chemical properties of furfural and lively, we can further as a manufacturing pharmaceuticals, pesticides, perfume intermediates, such as the production of furoic acid, 2 – methyl-furan, furan, levulinic acid and so on. 80% ~ 90% of the alcohol is consumed in furan resin, also for the production of THFA.
Tetrahydrofurfuryl alcohol is mainly used for special solvents and chemical intermediates, solvents such as pesticides, industrial and household cleaners, paint remover, with its acrylate, methyl acrylate can be used as the reaction of unsaturated polyester monomer, its latest use is in the electronics industry using its preparation of cleaning agent, which may be tetrahydrofurfuryl alcohol in the future market demand, the fastest-growing areas. A small number of alcohol for the production of friction wheel with the high temperature phenolic resin binder, such as automobile brake pads and so on. In addition, production of furfuryl alcohol or perfume, fragrance, pharmaceutical, pesticide intermediates. More use of Furfural and Furfuryl Alcohol to be further developed.
Second, the export situation is gratifying
In recent years, China’s total exports of furfural and furfuryl alcohol volume 60000 ~ 9 million tons in 2004, l ~ 5 Exports amounted to 27,112.6 tons, exports amounted to 23.0008 million U.S. dollars, the products are mainly exported to Japan, South Korea, the United States, Belgium , Thailand, Jordan, Iran and Turkey, and China’s Taiwan. Furfural reduction of China’s export volume in recent years, but the furfuryl alcohol and furan resin in the international market more competitive. Belgium Quaker Oats Chemical Company is Europe’s largest manufacturer of furfuryl alcohol and furan resin, furfural is also China’s second largest trading partner, by way of re-export trade in the Middle East and Eastern Europe, China and other countries also imported and processed products of furfural. Two years ago, the export prices of furfural and furfuryl alcohol at one time dropped by 40% or more (based on corn-cob 200 ~ 250 yuan / tons, furfural production costs 3,000 ~ 3,500 yuan / ton, furfuryl alcohol in the 5000 ~ 5500 yuan / ton, furfural once dropped to 500 U.S. dollars / ton, furfuryl alcohol dropped to 620 U.S. dollars / ton cost price, so China’s production of furfural and furfuryl enormous impact on business efficiency.
Third, global competitiveness have obvious advantages
China’s production of furfural and furfuryl alcohol resources, technology, economic and market a variety of competitive advantage, development of furfural and furfuryl alcohol and downstream production of realistic and long-term interests.
1. Abundant sources of raw materials
Most of China’s production of furfural using corncob as raw material, about 10 tons of raw materials to produce 1 ton of furfural. Ours is a large agricultural country, maize output 110 million to 1.3 million tons, annually 20 million t of corn cob, can be produced 2 million tons of furfural. Sugar cane residue, wheat shells and rice hulls, and other resources, yet the use of these resources are renewable resources, it is estimated China’s annual potential of more than 4 million t of furfural raw material resource.
2. Maturity of the technology
China’s existing furfural devices are used 10 to 20 cubic meters of acid-resistant material lining the hydrolysis reactor in series, process and equipment is relatively simple, low investment, fast construction, when effective, easy-to-promotion, suitable for small and medium enterprises. Furfural Hydrogenation is the early production of alcohol, whether the introduction of gas-phase or liquid-phase self-developed technologies are mature, and plant in the vicinity of the small fertilizer plants, the use of synthetic ammonia exhaust gas, access to low-cost hydrogen source, is to reduce alcohol cost effective way.
In 2002 I examined in the United States has been discontinued OMAHA City Penn’s 2 million ton / year installation of furfural and furfuryl alcohol, furfural production of 100 cubic meters of ball-type cooking kettle, large and complex materials, gas transportation and slag system so that construction costs and energy consumption significantly increased, but the yield of furfural, and other key economic and technical indicators are not advanced, so the device face of cheap imports of China and the shutdown of furfural is the inevitable result of the auction. Furfuryl alcohol by gas hydrogenation unit, similar to domestic technology, but also due to stop production for the same reason.
3. Significant social benefits
China’s furfural and furfuryl alcohol production enterprises are mostly small and medium sized rural enterprises on the prosperity and development of rural economy and increasing rural employment opportunities, increase rural incomes and increasing rural electricity supply and so has a practical significance. The raw materials for furfural production of renewable resources to maize production season 500kg / mu meters, 100kg-product corn cob to corn cob 200 yuan / tonne basis increase the income of peasants 20 yuan / mu. Building a capacity of l million tons / year of furfural and furfuryl alcohol devices, invested about 40 million to 5,000 million, could provide more than 500 local rural fixed and hundreds of temporary employment opportunities and an increase of 200 million farmers or direct income. Accompanied by a small amount of hydrolysis residue of furfural fuels coal, can be built 6000kW / h power generation equipment, in addition to their own use for things other than also for the local government can bring million yuan per year in taxes. If we continue to produce the downstream products, its effectiveness will be even greater.
4. Strong demand for downstream products of furfural and furfuryl alcohol-rich downstream products, pending further development, especially worth mentioning is that from the direct production of furfural can be tetrahydrofuran, poly-THF is the production of polyurethane and polyurethane elastomer materials, one of China’s current annual 100,000 t or more market. Quan Co., Ltd. Shandong, the introduction of gas-phase furfural has been Russia’s system of tetrahydrofuran technology, Jilin Qianguo Penn’s refinery from the U.S. introduction of liquid phase processes.
Fourth, expand the scale and strengthening governance
Protection and enhancement of our production of furfural and furfuryl competitive advantage, first of all to recognize our shortcomings and potential. There are two shortcomings, one the size of the problem the second is waste management.
Furfural production plant in China’s small and dispersed, more than 20 million tons / year capacity is distributed among more than 200 factories, large 3000-5000 tons / year, the smallest only a few hundred tons. Because of their size, economies of scale poor, and because of the failure to tie cinder power generation equipment, energy consumption is high; can not be recovered acetic acid, methanol, acetone and other by-products, affecting the economics of the device.
Furfural production of high energy consumption, the production of furfural 1t about 20t steam to produce acid, salt and furfural and other organic waste water of about 20t, distillation residue 0.1 ~ 0.2t, including methanol, acetone and other gas, waste 0 .5 ~ 0.8t, cinder produce large amounts of sulfur-containing flue gas emptying, in particular, on the surrounding groundwater contamination can not be ignored. The treatment of these wastes have a mature technology, simply because small-scale production, construction, the corresponding treatment facilities uneconomical.
The basic scale of furfuryl alcohol production facility in China in the 10000 t / a or so, mainly self-hydrogen source of the problem. Because small-scale construction of high cost of hydrogen source, affecting the economic and devices to increase.
If China is to protect and enhance the furfural, and alcohol industries, competitive advantage, its first production facilities to achieve the scale, resources, harmless. I believe that devices should be built in China furfural in corn or sugar cane-producing areas, the scale should be l million tons / year or more, about 10 million tons of corn core, quite 100 mu land corn production, in general, the transport radius of corn cob 50km within the framework of an economic, furfural plant to build the appropriate scale power generation facilities, waste treatment facilities harmless. Alcohol device should be at 2 million ton / year or more, self-hydrogen source. The size of tetrahydrofuran derivatives furfural important to be at 2 million ton / year over the production of derivatives of furfural devices can take a few months for the materials, can not be constructed in each of furfural plant production plant derivatives.
Furfural and furfuryl alcohol production and development in China today is very hard, but fragile. Industry-wide management, development, guidance, domestic and international trade, market analysis research and other mechanisms has not yet formed an urgent need to protect and enhance the entire industry a competitive advantage measures. Internally to prevent the disorderly competition, do not pass on the enterprise losses of farmers, the external active preparations to prevent and respond to foreign countries against Chinese products to implement anti-dumping complaints, otherwise the whole industry will bring about great losses.
The development of both furfural and furfuryl alcohol production to expand exports, but also a lack of savings and to replace our need to import large quantities of oil resources is the cause of China’s long-term development. Called on the government departments as soon as possible on the current good economic returns, to manage, with technical strength, there is a certain scale device companies provide policy support to enhance the economic strength for the entire development of the industry has played first, demonstration, promotion and guiding role.
