Introduction
Sulfuric acid (H₂SO₄) is one of the most important basic chemicals used in modern industrial production. It is widely applied in fertilizer manufacturing, non-ferrous metal processing, petroleum refining, chemical synthesis, battery production, and wastewater treatment. Due to its wide range of industrial applications, sulfuric acid production capacity is often regarded as an important indicator of a country's industrial development level.
China is currently the largest sulfuric acid producer in the world, supported by its strong chemical manufacturing base and large-scale metal smelting industry. Many sulfuric acid plants are integrated with copper, zinc, and nickel smelting facilities, allowing manufacturers to generate sulfuric acid as a valuable by-product during metal refining processes. This industrial integration has significantly strengthened China's position in the global sulfuric acid supply chain.
In recent years, the Chinese sulfuric acid market has also seen the rise of specialized chemical manufacturers focusing on high-purity acid, reagent-grade sulfuric acid, and customized industrial formulations. Among these companies, Lulong County Shuangyi Phosphorization Co., Ltd. has gradually established a reputation in the industry through its stable production capacity and expanding export network. The company operates a modern chemical facility in Qinhuangdao, Hebei Province and produces multiple grades of sulfuric acid along with aluminum sulfate products.
