Boiler Descaling

CHEMTEX'S Boiler Online Descalant is a unique formulation of organic and inorganic sequestrants and dispersants which are designed to keep the boiler internals free from scale, which are formed during operation. It slowly removes iron, calcium and magnesium scales during the normal boiler operation, and therefore called Online Boiler Descalant.

Key Features and Benefits

• No Downtime or shutdown required
• Non-Corrosive to metallurgy
• Does not require a separate cleaning circuit and hence is easy to use Saves Man-power
• Economical
• Saves power by removing scales

Application and Dosage
CHEMTEX'S Boiler Online Descalant is maintained in the boiler at 10-20ppm dosage in feed water until scale deposition is removed from the boiler. Blow down rate should be increased to remove the loose and liquefied scale from the boiler.

CHEMTEX'S Boiler Online Descalant should be added continuously in the feed water tank along with other treatment chemicals. It is preferable to dose the product in the boiler feed water line for effective utilization.

For designing the dosing system, concentration and for further technical assistance please contact your CSL technical representative.

Application and Dosage
Prepare a solution of 10% w/w CHEMTEX'S Liquid Boiler Descalant in preheated water (preferably) at 70-80oC. The descalant solution should be prepared 10-20% in excess of the system hold up volume. Re-circulate the solution using an acid compatible pump (with polypropylene impeller) for maximum of 6 hours. After descaling is completed, Flush out the solution and rinse once with plain water. Passivate the system with 2% w/w PASSIRINSE\AE solution in water and recirculate for an hour at ambient temperature. Passivation is done to avoid flash rusting after descaling.

CHEMTEX'S Sulfamic Descalant is an efficient descaling agent and is used for cleaning of a variety of industrial equipments and domestic appliances. CHEMTEX'S Sulfamic Descalant can be used for removing water and process scales from industrial equipments. Broadly these find use in the chemical and fertilizer industry, dairy and food equipments, brewery equipment, marine equipment, sugar industry etc.

CHEMTEX'S Sulfamic Descalant is non-inflammable and, unlike Hydrochloric Acid, does not give off obnoxious fumes. The safety of CHEMTEX'S Sulfamic Descalant has been further increased by the addition of corrosion inhibitors and other chemicals to make CHEMTEX'S Sulfamic Descalant a versatile descaling agent which is safer still in terms of equipment corrosion and safety of personnel.

The field of descaling is wide and the exact application of CHEMTEX'S Sulfamic Descalant can only be determined after considering the nature and extent of scaling, and the type of equipment that is to be descaled.

Key Features and Benefits

• Inhibited product to prevent corrosion while descaling
• Better descaling efficiency
• Low product concentration required for descaling

Application and Dosage
CHEMTEX'S Sulfamic Descalant is used in various applications and at different concentration ratio depending upon the amount and type of deposit and system parameters.

Normally for a system with hard scale deposits a 5-20% v/v solution is recommended. Preferably this solution should be made with pre-heated water at 70-80oC. The total volume of solution should be about 1.2 times of water holding capacity of equipment to be descaled. Recirculate the solution for about 6 hours using an acid compatible pump. After descaling it is necessary to passivate system with 2% solution of ALSTASCALETM PS20 into the last rinse and return to normal service.

Important

• For extremely rock hard and thick scaling it is recommended to soften the scale prior to descaling by recirculating and soaking 5-10% solution of ALSTASCALETM SS22 for 2-3 hours followed with rinsing with plain water before dosing descalant.
• In case of high silica and iron deposits add 2-3 parts ALSTASCALETM SR60 of Sulfamic Acid.
• After dosing chemical never heat solution by firing burners.
