Hydrochloric acid is a strong inorganic acid that is used in many industrial processes. The application often determines the required product quality.
Regeneration of ion exchangers
An important application of high-quality hydrochloric acid is the regeneration of ion exchange resins. Cation exchange is widely used to remove ions such as Na+ and Ca2+ from aqueous solutions, producing demineralized water.
Na+ is replaced by H3O+
Ca2+ is replaced by 2 H3O+
Ion exchangers and demineralized water are used in all chemical industries, drinking water production, and many food industries.
pH Control and neutralization
A very common application of Hydrochloric acid is to regulate the basicity (pH) of solutions.
OH- + HCl H2O + Cl-
In industry demanding purity (food, pharmaceutical, drinking water), high-quality Muriatic acid is used to control the pH of process water streams. In less-demanding industry, technical-quality hydrochloric acid suffices for neutralizing waste streams and swimming pool treatment.
Pickling of steel
Pickling is an essential step in metal surface treatment, to remove rust or iron oxide scale from iron or steel before subsequent processing, such as extrusion, rolling, galvanizing, and other techniques. Technical-quality HCl at typically 18% concentration is the most commonly-used pickling agent for the pickling of carbon steel grades.
Fe2O3 + Fe + 6 HCl 3 FeCl2 + 3 H2O
The spent acid has long been re-used as ferrous chloride solutions, but high heavy-metal levels in the pickling liquor has decreased this practice.
In recent years, the steel pickling industry has, however, developed hydrochloric acid regeneration processes, such as the spray roaster or the fluidized bed HCl regeneration process, which allow the recovery of HCl from spent pickling liquor. The most common regeneration process is the pyrohydrolysis process, applying the following formula:
4 FeCl2 + 4 H2O + O2 8 HCl+ 2 Fe2O3
By recuperation of the spent acid, a closed acid loop is established. The ferric oxide by product of the regeneration process is a valuable by-product, used in a variety of secondary industries.
Hydrochloric Acid is not a common pickling agent for stainless steel grades.
Production of inorganic compounds
Numerous products can be produced with hydrochloric acid in normal acid-base reactions, resulting in inorganic compounds. These include water treatment chemicals such as iron(III) chloride and polyaluminium chloride (PAC).
Fe2O3 + 6 HCl 2 FeCl3 + 3 H2O
Both iron(III) chloride and PAC are used as flocculation and coagulation agents in wastewater treatment, drinking water production, and paper production.
Other inorganic compounds produced with hydrochloric acid include road application salt calcium chloride, nickel(II) chloride for electroplating, and zinc chloride for the galvanizing industry and battery production.
Production of organic compounds
The largest Hydrochloric acid consumption is in the production of organic compounds such as vinyl chloride for PVC, and MDI and TDI for polyurethane. This is often captive use, consuming locally-produced Muriatic acid that never actually reaches the open market. Other organic compounds produced with Muriatic acid include bisphenol A for polycarbonate, activated carbon, and ascorbic acid, as well as numerous pharmaceutical products.
Domestic and Industrial as cleaning Compound :
Hydrochloric acid is a fundamental chemical, and as such it is used for a large number of small-scale applications, such as leather processing, household cleaning, and building construction. In addition, a way of stimulating oil production is by injecting Hydrochloric acid into the rock formation of an oil well, dissolving a portion of the rock, and creating a large-pore structure. Oil-well acidizing is a common process in the North Sea oil production industry.
Many chemical reactions involving Hydrochloric acid are applied in the production of food, food ingredients, and food additives. Typical products include aspartame, fructose, citric acid, lysine, hydrolyzed (vegetable) protein as food enhancer, and in gelatin production. Food-grade (extra-pure) Muriatic acid can be applied when needed for the final
COLD water is recommended for drying or semi-drying oils to flush the tank as prewash. Chemical expert suggest that cold water should be carried out immediately after discharge of cargo to prevent hardening of oil residues. Otherwise if oil is nondrying then Prewash of the tank with hot water at 50˚C is good decision to achieve BEST cleaning result.
Using Procedure:-
First of all flush the system with cold water to prevent evaporation rates and polymerization then the most economical method of using RXSOL-20-2008-HCF is by direct injection followed by recirculation washing, using tank cleaning machines.
Spraying Method:-
Using HCF as delivered in drums, spray onto areas where residue remains following rough washing leave for 10-45 minutes (but do not allow to dry), then butterworth at maximum pressure and warm water 60oC for at least 3 hours, checking that there is no foam remaining in the final stages. Inspects tanks(s) and if desired result has been achieved fresh water rinse and dry.
**Make sure to take all safety precautions are followed when handling / spraying HCF**
Injection Method– not applicable.
Re-circulation Method:–
Fill tank with fresh water and heat up to warm 50oC . IF a drop line is available on the tank line system, then start to circulate the water and add the required amount of Caustic flakes and HCF to make a 2.5% solution. A stronger solution can be made, but be advised that too much Caustic and too high temperature will result in white powder all over the tank. Under normal circumstances, between 2.5% and 4.5% will be sufficient strength. If there is no drop line, then lower butterworth hoses into the tank from the pump stack header without machines attached and circulate through these hoses while you fill the solution material.
* Use a strainer at the pump stack when circulating any solution.*
Question : How to clean veg oil ?
Answer : Following step can be follows to clean VEG OIL...
Step 1
Don't expose empty tank in air. Try to keep cool temperature inside the tank. Remove any remaining oil residue by gravitational and manual stripping, If possible Dampen a soft, clean cloth or rag under cool to room temperature water. Wring the cloth. The cloth should be damp, not dripping wet.
Step 2
If posible Lay the dampened cloth over the vegetable oil. Push downward to absorb as much oil as possible. Do not rub or wipe the oil. Lift the cloth.
Step 3
Spray and Sprinkle Hydrocarbon Remover HCF over any remaining vegetable oil. HCF cleaner will emulsify the oil, Allow the product to complete reaction for approximately an hour.

Question : Why uses of alkaline cleaner prohibited to clean fatty acid contains substances like veg oil, Animal oil etc ?
Answer : Neutral HCF supplier and stockist at all Indian and UAE - Middle East Coastal. HCF Neutral chemical importance is to emulsify vegetable oils and animal oils and fats residue with less foaming effect. Chemically if you can understand oil and fat which contain FATTY ACID while the general cleaner is alkaline in nature which is resulting greasy mass oncoming contact with Fatty Acid and Alkali cleaning material. To avoid the formation of GREASE like substance inside the tank, it is very important to take care of an alkaline cleaner with such cargo. On the other hand HCF Neutral ( free from any kinds of alkali mixture ) emulsifying oils particle and makes water soluble to remove from zinc-silicate coated tanks surface.

Hydrazine Hydrate Amine used as Oxygen scavenger on ultra high pressure industrial sites
No oxygen is entering the boiler with the feed water when hydrazine is present in the water.
The objective is to maintain a hydrazine residual between 0.05-0.2 ppm depending on operating pressure and boiler designe. Actual consumption is determined under operating conditions. A normal dosage is approximately 1 ltr. per day, depending of system layout.
Hydrazine is a convenient reductant because the by-products are typically nitrogen gas and water. Thus, it is used as an ANTIOXIDANT, an oxygen scavenger, and a corrosion inhibitor in water boilers and heating systems.
Hydrazine is mainly used as a foaming agent in preparing polymer foams.
No oxygen is entering the boiler with the feed water when hydrazine is present in the water.
