Excess capacity hinders the development of sulfuric acid industry to enter the adjustment period

As an indispensable raw material for the production of phosphate compound fertilizer,

is related to the price and market trend of chemical fertilizer in sulfuric acid industry. In recent years, with the rapid development of China's sulfuric acid industry, sulfuric acid production capacity has ranked the first in the world, but the problem of overcapacity followed, the chemical fertilizer market structure has also been affected. China one belt, one road China, is now in the "13th Five-Year" year. The China sulphuric acid industry association has published the "13th Five-Year development plan" for the sulphuric acid industry, and has made a scientific plan for the current overcapacity. It hopes to use the "heavy belt and one way" and "made in China 2025" strategy to expand the sulphuric acid industry and go to the world. The

and

sulfuric acid industry layout is more reasonable.

and

review the past decade, which is a decade of rapid development of China's sulfuric acid industry. After years of development of China's sulfuric acid industry, especially the rapid development in recent ten years, the design and manufacture of sulfuric acid plant have reached the world's advanced level, and remarkable achievements have been made in localization and large-scale production. The production capacity and output of sulfuric acid rank first in the world, meeting the needs of various downstream industries for sulfuric acid. China's sulfuric acid production has been the first in the world since 2003. According to the statistics of the association, in 2015, China's sulfuric acid output was 96.73 million tons, accounting for 36% of the world's total output, which provided guarantee for the demand of phosphate compound fertilizer, chemical industry, non-ferrous metal, textile, steel and other industries downstream of sulfuric acid.

and

at the same time, the distribution of sulfuric acid industry in China is more reasonable, and the industrial concentration is further improved. According to statistics, as an important raw material for the production of phosphate compound fertilizer, sulfuric acid plants in China are mainly concentrated in phosphate compound fertilizer producing areas and industrial developed areas. In terms of provinces, the annual output of sulfuric acid in the four phosphorus provinces (Yunnan, Guizhou, Hubei and Sichuan) totaled 42.4 million tons in 2015, accounting for 43.8% of the national total. There were 22 enterprises with a production of more than 1 million tons in 2015. The total output of the top ten enterprises was 31.52 million tons, accounting for 32.6% of the total output. These figures are enough to prove that the distribution of sulfuric acid production capacity in China is more scientific and reasonable, and the industrial concentration is gradually increasing.

,

in 2008, China's diammonium phosphate encountered a roller coaster on the price, the main culprit was sulfur, which caused serious losses to many enterprises and farmers. Therefore, we should reduce the dependence on foreign sulfur. " One fertilizer practitioner laments when he recalls the market in 2008. However, after the changes of market structure in recent years, the dependence of sulfur resources on foreign countries is declining. According to statistics. In 2015, China's total sulfur consumption was 35.44 million tons, up 4.4% year-on-year; of which, 18.62 million tons of imported sulfur resources were imported, and the external dependence of sulfur resources was 52.5%, which was 4% lower than that in 2010. With the growth of China's oil and natural gas production, China's sulfur recovery output is increasing year by year. In 2015, the domestic sulfur production was 5.74 million tons, an increase of 80% compared with the output of 3.2 million tons in 2010. The sharp increase of domestic sulfur production directly leads to the decline of the dependence of sulfur resources on foreign countries. Another gratifying trend is that the proportion of acid used for chemical fertilizer is declining. In the consumption of sulfuric acid in 2015, the proportion of acid used in chemical fertilizer was 61.7%, which was 8.1% lower than that in 2010. Generally, the proportion of chemical fertilizer acid and industrial acid is 50% respectively in the world. The decline in the proportion of chemical fertilizer acid in China also reflects the achievements of China's industrial transformation and upgrading. The overcapacity of

hinders the development of the industry.

. However, the dialectical analysis of the problem of dependence on sulfur resources in China shows that although the degree of dependence has decreased, the problem of insufficient guarantee of sulfur resources in China is still a major problem in the development of the industry. Most of China's oil is low sulfur oil, and less sulfur is recovered from oil. The sulfur resources in China are mainly recovered sulfur from natural gas, pyrite and associated sulfur of non-ferrous metals. Due to the rapid development of China's nonferrous metal smelting industry and the shortage of domestic non-ferrous metal ore supply, China needs to import a large number of non-ferrous metal ores every year, and the sulfur resources brought in gradually increase. Although the domestic sulfur production is growing, it is still difficult for China's sulfur resources to decline significantly in the short term. At the same time, the problem of excessive production capacity of sulfuric acid in China is the top priority for the development of the industry. According to statistics, by the end of 2014, China's sulfuric acid production capacity was 124 million tons, the actual output was 92.51 million tons, and the capacity utilization rate was only 75%. The sulfuric acid market has been in a state of oversupply for a long time. Coupled with the impact of a small amount of low-cost imported sulfuric acid, the price of sulfuric acid has remained low for a long time, and the profitability of individual sulfuric acid production enterprises has been reduced, and they are unable to develop new products and control pollution. In the future, there are still some large-scale non-ferrous metal smelting projects in China, and the sulfuric acid production capacity will continue to increase. Therefore, excess capacity of sulfuric acid is the most critical problem that perplexes the development of the industry.

and

then, why is the current situation of excess sulfuric acid production capacity in China? China's economic development has entered the "new normal". The mode of economic development is changing from extensive growth of scale and speed to intensive growth of quality and efficiency. The economic structure is changing from incremental capacity expansion to deep adjustment of adjusting stock and doing excellent increment. The driving force of economic development is shifting from traditional growth point to new growth point. The sulfuric acid industry is a typical basic chemical industry. Phosphate compound fertilizer, titanium dioxide, chemical fiber textile and other industries in the downstream of sulfuric acid are related to the lifeline of the national economy. Therefore, the growth rate of China's economy can basically reflect the growth rate of downstream demand of sulfuric acid. In the past ten years, China's economy has been growing rapidly. Sulfuric acid plants have been blooming all over the country, and the output of sulfuric acid has been increasing by double digits for many years. However, at present, China's economy has entered a growth rate shift period, the demand growth of sulfuric acid downstream is obviously slowing down, and the sulfuric acid industry has entered a difficult adjustment period.

therefore, from the current industrial situation, the development of sulfuric acid industry during the "13th five year plan" period faces many challenges. Firstly, how to eliminate excess capacity, restore market vitality and improve the profitability of the industry; secondly, under the background of slowing economic growth, how to develop new sulfuric acid products to adapt to the industrial demand in the new economy, promote sulfuric acid consumption, and further increase sulfur Thirdly, how to develop and apply new technologies to recover sulfur resources, expand the supply of domestic sulfur resources, and improve the degree of protection of sulfur resources in China under the situation of severe shortage of sulfur resources in China. At the same time, it is also necessary to face the problems of clean production and the impact of imported sulfuric acid.
