The plant also optimizes GACL's core chlor-alkali operations via effective chlorine integration
Gujarat Alkalies and Chemicals Limited (GACL) has marked a significant operational milestone with the launch of its purified and food-grade phosphoric acid plant at its Dahej complex in Gujarat.
The facility boasts an operational capacity of 33,870 tonnes per annum (TPA) at 85% (H3PO4) (equivalent to 21,000 TPA at 100% (P2O5). Built with a total capital investment of Rs. 520 crore, the project is strategically positioned to strengthen the company’s specialty chemicals portfolio.
A major objective of this expansion is import substitution. India currently relies heavily on imported purified phosphoric acid—historically consuming around 35,000 MTA annually—making GACL's facility vital for domestic self-sufficiency in the food, beverage, and industrial sectors.
The plant also optimizes GACL's core chlor-alkali operations via effective chlorine integration. By utilizing byproduct chlorine to synthesize hydrochloric acid (HCl), which feeds the phosphoric acid process, GACL insulates its operating margins from volatile merchant chlorine prices.
To support this, the board has approved a new Rs. 55 crore HCl synthesis unit at the site. This launch aligns with GACL's broader green growth strategy, which includes elevating its renewable energy integration to lower power costs.
