Located in the Shuangliao Economic Development Zone Chemical Park, Shuangliao Haohua draws on strong process technology and abundant raw materials to extend its industrial chain and support the local economy.
The park’s automated workshops are running the relocation of the 200,000 t/y membrane caustic soda plant, a project in the NDRC major-project database. Built in three phases with RMB 1.72 billion of investment over 800,000 m2, it will produce caustic soda, chlorine, food-grade high-purity hydrochloric acid, sodium hypochlorite and hydrogen. The membrane electrolyzers have been upgraded to world-leading zero-gap technology.
A DCS distributed control system provides real-time data acquisition, equipment and alarm monitoring, closed-loop control, configuration, commissioning and diagnostics. Standardised, integrated and fast, it unifies production and management control and keeps the plant running safely and stably.
Output reached RMB 420 million in 2023. The company plans to release a further 100,000 t of caustic soda capacity in line with the provincial 14th Five-Year Plan target of a Shuangliao chlor-alkali base, and is preparing new expansion projects to build a denser industrial cluster and move the park toward RMB 10 billion in annual output.
