In 1926, it produced 'Red Triangle' brand soda ash with excellent quality, which won the gold medal at the Philadelphia Universal Exposition of the U.S.A. in the same year and the gold medal at the Belgian Industrial and Commercial Exposition in 1930.
In 1937, the Japanese invasion, Tanggu fell, the alkali plant all colleagues to protect the national spirit, move the plant south to Sichuan Gandhara County, Wutongqiao old dragon dam and renamed 'new Tanggu', construction Yongli Chuan plant, open up the West China chemical base.
In 1941, under Dr. Hou Debang's intensive research and repeated tests, a new process of combining ammonia synthesis and ammonia-alkali method to produce alkali was invented - 'Hou's Alkali Method' (Combined Alkali Method).
Tanggu was liberated in 1949, and the plant was reborn and the production was developed. 1952, the plant was formally put into public-private partnership and became the first public-private partnership enterprise in China. From 1970 to 1978, the state invested in the completion of the first phase of the 'United Alkali' project, and completed the construction of the water supply project, slag discharge project, food alkali project and self-supporting high-pressure thermal power plant project. 1994, the use of low-interest loans from the Asian Development Bank carried out slag dumps Phase II, synthetic ammonia, steam-absorbed ammonia, heavy soda ash four energy-saving renovation to reduce the cost of production and improve the economic efficiency.
Tianjin Soda Ash Plant now covers an area of 4.69 million square meters, mainly produces soda ash, heavy soda ash, ammonium chloride, compound fertilizer, reconstituted salt, baking soda, sodium metasilicate, synthetic ammonia, edible carbon dioxide, 74% calcium flake, carbon dioxide, argon, water quality stabilizer, snow killer and other 12 categories of 22 products. Among them, 6 products were honored with the title of Ministry of Excellence and Municipal Excellence, and the soda ash won the International Gold Medal for 4 times and the National Gold Medal for three consecutive times.
Since the reform and opening up, Tianjin Soda Ash Plant has been aiming at the international advanced level, adopting a large number of energy-saving, high-efficiency and large-scale alkali equipment and using electronic computer control in management through self-development and introduction, and the degree of automation control has partly reached the domestic leading level.
At the same time, Tianjin Soda Ash Plant, in line with the guiding principle of 'comprehensive governance to protect the environment', in the process of enterprise reform and expansion, and endeavor to increase production without increasing the loss, and successively carry out the dust removal, waste gas, waste liquid recycling of some major production equipment, so that the emissions are always kept below the national standard.
