Generally, due to the limited scale of HCL gas sales, it is used to produce hydrochloric acid or downstream products derived from HCL.
They are generally available now, but more often, chlorine and hydrogen are burned to produce hydrochloric acid, which is then used as a raw material for downstream products. The price of hydrochloric acid is very low these days; 40% hydrochloric acid costs around 400-500 yuan, and in some places the price is even around 300 yuan lower.
I wonder if Shinryu Denka produces hydrogen chloride gas
Generally, chlor-alkali companies have hydrogen chloride, but they sell hydrochloric acid; few sell hydrogen chloride
In the chlor-alkali industry, chlorine gas is typically balanced by producing liquid chlorine, hydrochloric acid, or sodium hypochlorite. Since hydrogen chloride gas is difficult to transport, it is usually absorbed to form hydrochloric acid. The current market price of hydrogen chloride gas is approximately 6,500 yuan per bottle, with each bottle weighing 27 kilograms.
Typically, chlor-alkali plants produce hydrogen chloride gas, but this gas is mainly used in the production of PVC downstream. Any excess hydrogen chloride gas is absorbed with pure water and then sold directly.
For the chlor-alkali industry, the main products are NaOH and PVC resin, while the by-products include hydrochloric acid, liquid chlorine, and sodium hypochlorite. Hydrogen chloride is a raw material for PVC; some factories are now investing in ion-exchange membrane projects because this technology allows them to produce hydrogen chloride gas, which is used as a raw material in the production of polycrystalline silicon. Hydrogen chloride is generally produced for internal use, with a price of around 300 RMB per metric ton, although this price can fluctuate
It does not exist under standard conditions, but can be produced under specific temperature and pressure conditions
