Products significantly enhance the self-sufficiency rate to further expand the application fields
December 19 , reporters from the New Materials Co., Ltd. Nanjing Nuoao informed , as the company’s new 120,000 t and 100,000 t of propionaldehyde propanol stable device operation , in 2014 the production capacity of n-propanol reached 185,700 tons , has to meet the domestic market demand. Next few years, China’s import dependence on n-propanol will be further reduced , and gradually achieve self-sufficiency. Meanwhile, as the environmentally friendly alternative to the process of ” BTX” etc. accelerated solvent , n-propanol market demand will show a sustained growth.
Import dependency situation will ease
It is understood that a wide range of downstream applications propanol , can be directly used as a solvent or synthetic n-propyl acetate , a solvent used in paints , printing inks , cosmetics, etc. , can also be used in the synthesis of pharmaceuticals, pesticides , feed additives, synthetic fragrances , plasticizers and cleaning agents. In recent years , with increases every year environmentally friendly solvent consumption, n-propanol market demand continued to show growth. However, due to lack of domestic supply of n-propanol , n-propanol, China’s imports grew from about 17,000 tons in 2008 to 2012 more than 38,000 tons , import dependence in 2012 reached about 40%.
“With the successful commissioning of new materials Co., Ltd. Nanjing Nuoao propanol device , in 2013 China’s import volume of n-propanol after year 2013 will reduce the amount of n-propanol is expected to import 3.8 million tons ; . 2014 will drop to 2.8 million tons ; .. 2015 or further dropped to about 20,000 tons in the coming years , China will import farewell propanol history , ” Cho Chong Yang Xianghong , senior vice president of information told reporters .
Further expand the market space
On the future development of n-propanol market , Yang Xianghong expressed optimism. He believes that with the rapid development of coatings , paint , ink, adhesives and other major downstream industries and continuously improve national environmental requirements for that type of product , as well as enhance consumer awareness of environmental protection , especially in paint, ink and other industries . ” triphenyl ” restricted amount of solvent consumption propanol toxicity will continue to grow . Moreover , n-propanol boiling point , evaporation rate index is moderate, is also expected to replace n-butanol, isopropanol, acetic acid esters larger amount of paint solvents , at present, China ‘s annual production of isopropyl alcohol will only reach 90 million tons , if there is a partial substitute for the words , n-propanol currently ten million tons production capacity is clearly not enough.
The main downstream products for n-propanol , n-propyl acetate, future prospects , Yang Xianghong also very good. 2013 n-propyl acetate domestic production is estimated at around 11 million tons, accounting for 65% of the total consumption of n-propanol . Due to highlight the boiling point , compatibility, solubility and evaporation rate and other physical and chemical properties , n-propyl acetate as the main solvent coatings obvious advantages , low toxicity characteristics also make it an alternative ” BTX” the best choice of solvents one . After the implementation of the new Food Safety Law , packaging products benzene content is strictly limited , so printing inks have used instead of the previous n-propyl acetate solvent benzene , n-propyl acetate consumption in the rapidly growing field of food packaging .
Since 2003 , China’s production capacity of n-propyl acetate rapid growth in 2010 and 2012 the average annual growth rate of over 15%. Yang Xianghong predicted : “The next five years , the amount of n-propyl acetate in coatings, inks, and adhesives in the field of construction have increased more than 10 times the annual demand will reach 400 million tons , and the current n-propyl acetate annual consumption in the coating only about 4,000 tons . ” this will lead to a further increase in demand for n-propanol .
Yang Xianghong analysts believe that , at present, the domestic market demand for n-propanol not fully released, the main reason is little domestic production enterprises , lack of self-sufficiency rate of raw materials , supply, price volatility , the positive impact on downstream users , making n-propyl acetate plant operating rate is generally low . The New Materials Co., Ltd. Nanjing Nuoao 100,000 tons went into operation propanol device will effectively ease the tight supply and demand contradiction.
Domestic material cost advantage in
In addition to considering the toxicity , boiling point , evaporation rate and other properties , the material cost is an important consideration when selecting a solvent for downstream users . With the increase in domestic supply of n-propanol , n-propanol domestic costs will be more reasonable and stable.
” Nuoao aldehyde and n-propanol propylene production unit in Nanjing , not only can greatly improve the supply made in China , but also can be more prominent raw material cost advantage .” New Materials Co., Ltd. , general manager of Nanjing Nuoao Wangan Jun told reporters: ” prop- the main raw material for the aldehyde carbonyl group and n-propanol synthesis gas , hydrogen and ethylene in which the carbonyl synthesis gas and hydrogen from the Nanjing Chemical Industry Park, the largest industrial gas supplier – Nanjing Wison clean Energy Corporation purchases , long-term cooperation agreement will product quality and cost of procurement is well protected ; ethylene is currently part of the purchase in Wison partly rely on imports, Nuoao dock lease in Lung ethylene storage tank on the international market can effectively dilute our low ethylene production costs , reducing the possibility of significant fluctuations in product costs . ”
“In addition, propionaldehyde, n-propanol main users are mostly concentrated in the Yangtze River Delta region , the new plant is located in the Nanjing Chemical Industry Park Orvieto , located in the Yangtze River Delta region , close to the user , and convenient transportation , the product can be easily and quickly transported to the downstream customer, significantly reducing transportation costs and time costs downstream customers . ” Wangan Jun added.
