Inhibitor for Citric ACID
Citric Acid corrosion Inhibitor is an organic, liquid, cationic corrosion inhibitor especially designed to inhibit the attack of Citric Acid during industrial cleaning operations. It also inhibits acid attack on copper and brass.
The addition of Acid corrosion Inhibitor Citric Acid inhibitors to Citric acid solution provides maximum protection for equipment during:
A. The removal of lime deposits or water scale from power plant boilers and piping systems and from evaporating equipment.
B. The removal of scale and deposits from equipment in refineries, utility companies,paper mills, chemical plants and other industries.
Citric acid is a weak organic acid. It is a natural preservative/conservative and is also used to add an acidic, or sour, taste to foods and soft drinks. In biochemistry, the conjugate base of citric acid, citrate, is important as an intermediate in the citric acid cycle, and therefore occurs in the metabolism of virtually all living things.
For each For each 1000ltrs of pickling bath Citric Acid Inhibitor must be added at the rate of 1 to 5ltrs (1.1 - 5.7kgs)* Citric acid solution, not less than the following amount of Citric Acid corrosion Inhibitor should be used:
The exceptional strength and heat stability of Citric Acid corrosion Inhibitor give the user a considerable safety factor in relation to temperature, acid strength, and time. Citric Acid corrosion Inhibitor may be added to either the diluted or concentrated Citric acid Solution. In either case, Citric Acid corrosion Inhibitor should be thoroughly mixed with the acid by stirring or agitation.
The hydrochloric acid solution inhibited with Citric Acid corrosion Inhibitor is best circulated through the equipment to be cleaned. When circulation cannot be accomplished, the equipment should be filled with the inhibited acid and allowed to react for sufficient time to remove the objectionable deposits. To estimate the proper acid concentration and cleaning time, samples of the deposits to be removed can be tested in the laboratory prior to cleaning. If heating of the equipment to be cleaned or acid solution is desired to speed the cleaning action, it should be done prior to the start of the cleaning operation
Storage and Disposal
Citric Acid Corrosion Inhibitor and will not freeze at temperature as low as -20° Fahrenheit. Below 0° Fahrenheit, Citric Acid Corrosion Inhibitor become very viscous and may be difficult to pump. It is recommended that Citric Acid Corrosion Inhibitor be stored in a dry area where the temperature will not go lower than 0° Fahrenheit.
Applicable regulations concerning disposal and discharge of chemicals should be consulted and followed-
Disposal information for Citric Acid Corrosion Inhibitor is given on the Material Safety Data Sheet for each product.The industrial cleaning bath is acidic and contains Citric acid and organic Citric Acid Corrosion Inhibitor components. Waste treatment , neutralization is required. The industrial cleaning bath and sludge can contain ingredients other than those in the chemical as supplied and analysis of the solution and/or sludge is required before waste treatment and disposal.
Safety and Handling :
Before handling the chemical products used in this process, the first aid and handling recommendations on the Material Safety Data Sheet for should be read, understood and followed. The industrial cleaning bath is strongly acid and can burn skin and eyes. Refer to the Material Safety Data Sheet for hydrochloric acid for recommendations for protective action.
