Segmentation Analysis

By Grade

Co-Product Availability from Chlor-Alkali Processes Supports the Dominance of the By-Product Segment

Based on grade, the market is segmented into by-product, synthetic grade, and others.

The by-product segment holds the largest hydrochloric acid market share, due to its extensive production as a secondary output in chlor-alkali and chlorination processes. HCl is commonly produced during the manufacture of chlorine, Vinyl Chloride Monomer (VCM), and other chlorinated compounds, making it readily available at a large scale without dedicated production costs. This cost advantage and consistent supply make by-product hydrochloric acid highly preferred across industries such as steel pickling, chemical processing, and water treatment. As global production of chlorine and related derivatives continues to grow, the by-product segment remains dominant due to its economic and supply-side advantages.

• According to Occidental Petroleum, HCl is primarily produced as a co-product of chlorination and chlor-alkali processes, particularly during the production of vinyl chloride and other chlorinated intermediates.

The synthetic grade segment is expected to grow at a CAGR of 5.5% over the forecast period.

By End-Use Industry
