**The strong position of acid production is declining

In the first half of this year, although China's benzoic acid accounted for 49% of the total production capacity of the country, it was still in a dominant position, but the recovery of sour heads for acid production was increasing. The bulk of new production capacity was for metal smelting* * Device. By the end of the “Twelfth Five-Year Plan”, China’s ** production capacity will leap to 100 million tons, and the situation of the oversupply of ** has already taken shape. The domestic gambling market will compete in various raw material routes, and all kinds of acid production methods will win the survival of the fittest.

According to incomplete statistics, by the end of 2011, the country's annual production capacity was approximately 91.6 million tons. Among them, ** acid production is about 45 million tons, accounting for 49% of total capacity; smelting acid is 24 million tons, accounting for 26.2% of total capacity; * iron ore production is 22.7 million tons, accounting for 24.7% of total energy. There is also a small amount of gypsum, * hydrogen and other acid production.

Compared with the data at the end of 2010, the status of benzoic acid in total capacity has not changed significantly. By the end of 2010, China's production capacity was about 84 million tons per year, of which, about 40 million tons of acid production per year. However, this year, from the perspective of new installations, Guizhou, Hubei, and Sichuan are currently building large-scale phosphorus compound fertilizer plants supporting large-scale sulfuric acid plant capacity of nearly 4 million tons/year, supporting other industries for the purpose of energy demand.** Acid production, with a capacity of about 3 million tons/year. In addition to this, it should be emphasized that the bulk of ** capacity growth is the new Copper, zinc, and lead smelter facilities built in the first two years of the “Twelfth Five-Year Plan”. The capacity that has been put into production in 2011 is 4 million tons/year. In 2012, the capacity will be gradually put into operation in 2012 will be about 7 million tons/year, and 2 million to 3 million tons/year of production capacity will be put into production in the future. There will be at least 10 sets of sulfur iron and iron sulfate treated with sulfuric acid titanium dioxide. Mineral acid plant with an annual production capacity of about 4 million tons.

In this game of different raw material acid production, non-ferrous metal smelting has the largest advantage of by-product acid production. The national economy has a hard demand for all kinds of non-ferrous metals. Although China's non-ferrous metal mines' dependence on foreign countries has been increasing year by year, especially the dependence of copper mines on foreign countries has exceeded 60%, major smelting enterprises seek resources abroad to accelerate domestic prospecting, Good progress has been made in the use of advanced technologies to increase the recovery of non-ferrous metals and resources. In order to maintain the narrow profits of non-ferrous metals, ** has the greatest competitiveness in the domestic market. Several major projects are close to coastal ports. It also created new opportunities for exporting or developing coastal markets.

With acid production from pyrite or sulphur sand resources, most of these SMEs are equipped with phosphate fertilizers and there is a certain market for sulphuric acid. Sulfuric acid titanium dioxide enterprises are also very competitive for the treatment of by-products of ferrous sulfate supporting the construction of ferricic acid.

At present, there are still other devices that use other sulfur resources to make acid in various places. Among them, the sulfur resources that should be fully utilized are the SO2 resources recovered by smoke boilers. The 600,000 tons high-concentration SO2 acid plant under construction in cooperation with Duyun Power Plant in Guizhou and Jifu is about to be put into production, opening up new resources for China. The anhydrite system** is also being constructed in a gypsum-rich mining area.

In general, the strong position of acetic acid is declining. Large-scale compound fertilizer enterprises and supporting the production of compound fertilizer **, this part of the product rarely go long dominated the surrounding market **, ** on the limited share of the market. In addition to the energy demand for the purpose of ** acid, a considerable part of which is to enter the market as a commodity, production capacity of 10 million tons / year or so, but these products are subject to smelting acid prices, market demand, raw material prices greater impact, companies in Volatility in market demand, turmoil in product prices, and difficulty in operating raw material prices. Moreover, the supply of international ** is still in a tight state in recent years, and ** acid production will be subject to price restrictions in the international market. It is difficult to suppress international ** prices due to the increase in domestic resources.
