Difficult progress in sulfuric acid industry

wallpapers News 2020-06-21

From June 9 to 11, the 2014 annual meeting of sulfuric acid industry sponsored by China sulfuric acid industry association the Third Council of the sixth session of China sulfuric acid industry association was held in Xi'an.

At the meeting, the market situation of sulfuric acid industry the achievements of energy conservation emission reduction became the focus of attention.

According to Wu Xuemei, executive vice president of China sulfuric acid industry association, in 2013, China's sulfuric acid prices were running at a low level throughout the year, some of the acid making plants reduced production or even stopped production.

At the same time, with the implementation of the pollutant discharge stards energy consumption stards, the industry is facing increasing pressure on energy conservation environmental protection, forcing enterprises to increase investment introduce new technologies equipment.

The industry is struggling in the cracks.

By the end of 2013, the national average price of 98% sulfuric acid was 240 yuan / ton, a year-on-year decrease of 27.3%. The main reasons for the downturn of sulfuric acid market are: 1) overcapacity.

2) continuous weakness of downstream phosphate fertilizer industry.

3) increased supply of smelting acid.

4) impact of imported acid.

The excess capacity of sulfuric acid in China is obvious.

According to incomplete statistics, by the end of 2013, there were 395 large-scale sulfuric acid production enterprises in China, with a sulfuric acid production capacity of about 118 million tons.

In 2014-2015, about 5.

1 million tons of sulfuric acid will be put into operation.

During the 12th Five Year Plan period, the production capacity of smelting acid will increase by more than 13 million tons, the production capacity will focus on this year next year.

At the same time, China's external dependence on sulfur resources is relatively high.

In 2013, domestic sulfur was 5.

57 million tons imported 10.

55 million tons.

The self-sufficiency rate of sulfur was only 35%.

In addition to the import of 1.

15 million tons of sulfuric acid, the external dependence of sulfur resources was 48%.

Wu Xuemei told reporters that as the main raw material of phosphate fertilizer production, the market situation of phosphate fertilizer also directly affects the operation of sulfuric acid industry.

As the phosphate fertilizer market situation is difficult to improve in the short term, the sulfuric acid market is still not optimistic this year.

With the increasing pressure of cost environmental protection the slowing down of market dem, it has become a major feature of sulfuric acid industry to promote industrial transformation development by technological progress in recent years.

In recent years, the waste heat recovery utilization level of sulfuric acid industry has been greatly improved, the low-temperature potential heat recovery technology of sulfuric acid has been comprehensively promoted.

By April 2014, 94 sets of low-temperature potential heat recovery units have been built under construction, accounting for more than 75% of the capacity of sulfur-based sulfuric acid production.

the first set of low-temperature potential heat recovery unit for sulfuric acid production from smelting flue gas was completed put into operation in Jinchuan, Guangxi, the first set of low-temperature potential heat recovery device for pyrite based sulfuric acid production was completed put into operation The demonstration plant has also been built.

According to the statistics of the association, in 2013, 115 sulfur-based sulfuric acid enterprises 190 mine based sulfuric acid enterprises recovered about 80 million tons of medium low-pressure steam, equivalent to saving 11 million tons of stard coal reducing 28.

1 million tons of carbon dioxide.

Meanwhile, with the continuous improvement of domestic sulfuric acid catalyst performance the application of various tail gas treatment technologies, the SO2 emission of sulfuric acid industry decreased significantly.

According to statistics, the SO2 emission of sulfuric acid industry in 2013 only accounted for 0.

35% of the national SO2 emission, which was 43.

8% lower than that of 2011.

Qi Yan, President of China sulfuric acid industry association, said: "in the future, it has always been the" green low-carbon dream "of the sulfuric acid industry to control the development of production capacity, eliminate backward production capacity with various access conditions, environmental protection indicators market means, promote scientific technological innovation, energy conservation emission reduction, guide the transformation development of the industry with technology, so as to make sulfuric acid enterprises become" energy factories ".

Background: in 2013, China's sulfuric acid output was 86.

5 million tons, with a year-on-year increase of 2.9%. Among them, 39.

67 million tons of sulfuric acid were produced from sulfur, with a year-on-year increase of 1.6%. 24.73 million tons of sulfuric acid were produced from smelting gas, with a year-on-year increase of 3.5%. 21.57 million tons of sulfuric acid were produced from ore, with a year-on-year increase of 3.0%. 530000 tons of sulfuric acid were produced from other raw materials, with a year-on-year increase of 2.2%. According to IFA data, China's sulfuric acid production accounted for 36.

5% of the world's total output in 2013.

In 2013, the apparent consumption of sulfuric acid in China was 87.

65 million tons.

The consumption of sulfuric acid in fertilizer accounted for 62.

4% of the total consumption of sulfuric acid, of which the acid for phosphate fertilizer accounted for 57.

2% of the total consumption of sulfuric acid.

The weak phosphate fertilizer market directly affects the dem for upstream sulfuric acid.
