Hydrochloric Acid (HCl)
An aqueous solution of Hydrogen Chloride gas, we formulate a wide range of Hydrochloric Acid (HCL) in LR Grade (35-36 %), which is preferred by a majority of customers for its most favorable characteristics. Possessing strong acidic qualities, Hydrochloric Acid finds a wide range of applications in the various fields such as, making of dyes, in phenols and plastics, chemicals intermediates, cleaning agents in domestic, commercial and industrial establishments.
Hydrogen chloride (HCl) is a monoprotic acid, which means it can dissociate (i.e., ionize) only once to give up one H+ ion (a single proton). In aqueous hydrochloric acid, the H+ joins a water molecule to form a hydronium ion,
H3O+HCl + H2O → H3O+ + Cl−
Hydrochloric acid is used for a large number of small-scale applications, such as leather processing, purification of common salt, household cleaning And building construction.
One of the most important applications of hydrochloric acid is in the pickling of steel, to remove rust or iron oxide scale from iron or steel before subsequent processing, such as extrusion, rolling, galvanizing, and other techniques
Hydrochloric acid is used to remove rust, scale and undesirable carbonate deposits in oil wells. This encourages the flow of crude oil or gas to the well. The various hydro-treating processes in a refinery include hydrodesulphurisation, hydroisomerisation, dearomatization and hydrocracking.
Hydrochloric acid works as an effective neutralisation agent for alkaline (high pH) effluent. It also helps in the regeneration of cationic resin bed.
