Production of soda ash
Production capacity and output of soda ash in China.In the early 1990s, China ended its dependence on imports and gradually became a net exporter of soda ash.Since 2003, China’s production capacity and output of soda ash ranked first in the world and reached a record high in 2014.By 2018, China had a production capacity of 31.15 million tons of soda ash and an output of 26.21 million tons.
Capacity and output of light and heavy alkali.In 2018, China produced 13.25 million tons of light alkali and 12.96 million tons of heavy alkali.From 2007 to 2018, the proportion of heavy alkali production increased from 30% to 49%, and the growth rate of heavy alkali production was much higher than that of light alkali.
Production capacity of soda ash in different production processes.By 2018, there were 44 soda ash production enterprises in China.Among them, there are 29 enterprises using the method of linking alkalis, most of which have a capacity of less than 1 million tons, mainly distributed in henan, hubei, jiangsu, sichuan and chongqing.There are 12 enterprises using ammonia alkali production method, most of which have a capacity of more than 1 million tons, mainly distributed in qinghai, jiangsu and shandong.There are only 3 enterprises using natural alkali method, among which 2 are located in henan and 1 is located in Inner Mongolia.
Distribution of soda ash productivity.Soda ash production in China is mainly concentrated in east China, central China and northwest China.East China’s jiangsu has a total capacity of 5.5 million tons, accounting for 46%;Henan in central China has a total capacity of 4.2 million tons, accounting for 66%;Qinghai in the northwest has a total output of 4.3 million tons, accounting for 83 percent.In 2018, the utilization rate of production capacity of soda ash in China was 84%. Soda ash production facilities are distributed in 22 provinces (cities and autonomous regions). Henan and qinghai have constantly released new production capacity due to their abundant raw material resources and geographical advantages.
In 2018, the production capacity of soda ash in central China was 6.36 million tons, accounting for 20% of the country’s total output.The production capacity of soda ash in northwest China has reached 5.15 million tons, accounting for 17% of the country’s total output. Qinghai’s production capacity is 4.3 million tons, accounting for 83% of the northwest and 14% of the country’s total output.In addition, the production capacity of soda ash in north China, southwest China, south China and northeast China accounts for 12%, 9%, 2% and 2% of the country’s total production capacity, respectively.
Concentration of soda ash industry.By 2018, there were 44 soda ash production enterprises in China.12 enterprises with annual production capacity of one million tons or more, with a total production capacity of 17.6 million tons, accounting for 56% of the total production capacity;13 enterprises with a capacity of 500,000 to 1 million tons, with a total capacity of 8.35 million tons, accounting for 27%;There are 19 enterprises under 500,000 tons, with a total capacity of 5.2 million tons, accounting for 17%.
Tangshan sanyou, China salt industry, jinshan chemical industry and yuanxing energy are the main large production groups in China’s soda ash industry, accounting for 10.91%, 8.44%, 6.42% and 5.78% of the total national production capacity, respectively, a total of more than 31%.
Demand for soda ash
Overall demand.China is the world’s largest soda ash consumer.With the development of economy, the consumption of soda ash in China is increasing.In 2018, China’s total demand for soda ash was 25.12 million tons, 660,000 tons less than 2017 and 6.35 million tons more than 2010, a total increase of 34% over the past eight years.The demand for heavy alkali was 13.47 million tons, up 64% from 2010.The demand for light alkali was 11.65 million tons, an increase of 10% over 2010. The contribution rate of heavy alkali demand to the total demand growth of soda ash reached 83%.The downstream demand for light alkali is growing slowly. In 2018, the national demand for light alkali is 11.65 million tons, an increase of 1.1 million tons compared with 2010.
Requirements structure.In the application field of soda ash in China, 4% of the soda ash is used in the food industry and belongs to edible soda ash.96% of the soda ash used in industrial production of raw materials or additives, belonging to industrial soda ash.Generally speaking, the production of 1 ton of plate glass requires 0.2 tons of heavy alkali, that is, a daily melting capacity of 1000 tons of float glass production line consumes 200 tons of soda a day.In recent years, the demand of plate glass industry for soda ash has been v-shaped.From 2013 to 2014, the demand of plate glass for soda ash remained above 11.6 million tons.In 2018, the glass industry consumed 13.03 million tons of heavy alkali, up 9.9% month-on-month, and the demand remained at a high level in the past five years.
Soda ash imports and exports
China is a net exporter of soda ash.In 2018, China exported 1.379 million tons of soda ash and imported 294,000 tons of soda ash, with a net export of 1.085 million tons.Compared with the total production and total demand of soda ash in China, the proportion of export and import is not high.
Since 2007, China has exported about 1.8 million tons of soda ash annually, accounting for about 8% of the country’s annual output.After 2009, the demand for soda ash in China has been stronger, and the profits of enterprises have been kept at a reasonable level. The export volume of soda ash in China has declined as a whole.Except for 2015, the export volume was less than 2 million tons, and in 2018, the export volume was 1.38 million tons.
