Recently, the hydrochloric acid market in Jiangxi is mainly stable. The output of hydrochloric acid should increase with the increase of local chlor-alkali plant load. Except for hydrochloric acid enterprises' own use, some commodities are mainly supplied to local metallurgy, sewage treatment and other industries. The supply of hydrochloric acid in the province mainly comes from chlor-alkali enterprises, and the market allocation is based on demand. Most of the downstream facilities are provided by the park, and the supply and marketing are basically stable. The range of by-product hydrochloric acid is not high, and the market operation actively promotes the quantity. The amount of hydrochloric acid synthesized is stable according to the demand, and the turnover range of the factory is temporarily stable.
