Seeking information on the mainstream synthesis methods and market trends for hydrochloric acid

If they do continue to produce it, is the main method the synthesis through the combustion of hydrogen and chlorine? Thank you all! hcbbs !! .

The most common method for producing hydrochloric acid is the combustion of chlorine gas and hydrogen gas, as hydrogen and chlorine are the main products in the chlor-alkali process. Developed countries also need to produce hydrochloric acid; however, the overall scale of production there is not as large as in China. But the production capacity of individual facilities can be quite high, meaning there are large-scale chlor-alkali plants and substantial amounts of hydrochloric acid produced. The proportion of hydrochloric acid produced as a by-product in some chemical manufacturing processes differs significantly from that of hydrochloric acid synthesized intentionally. Additionally, China has a large output and production capacity for industrial hydrochloric acid, but high-purity hydrochloric acid remains a weakness for the country.
In PVC production, hydrochloric acid should be produced as little as possible; it is sufficient to generate hydrogen chloride gas, with hydrochloric acid being merely a by-product.
