Chemtex manufactures Descalents which dissolves, disperse or purge scales in heat exchangers & pipelines.



Heat exchangers & pipelines are an essential element in chemical industries. They are known to accumulate rust, scale & soil deposits from time to time.Descalants or Descaling Agents are chemical compounds that effectively dissolves, disperse or purge these scales, rust and soil deposits from by means of re-circulation method, fill and soak method or immersion method.


Proper Corrosion Inhibitors are added in descalants to avoid damage to system metals.After acidic descaling of system, it is important to passivate and neutralize the system with proper Passivating Agents for avoiding chances of flash rusting after descaling.


In some cases Scale Softeners and mechanical means like brushing and scrubbing of tubes is also required for heavily fouled systems.

The dosing of these chemical is a  labour oriented job & requires huge downtime.Due to this the use of alternatives such as Online Descalants and Antiscalants are getting popular.

Chemtex offers a wide range of descalants under its registered trade names of ALSTASCALE for:-

  • ·       Heat Exchanger Descaling Chemical (Condenser Descalant)
  • ·       PHE Descalant (Plate Heat Exchanger Descaling Chemical)
  • ·       RO Membrane Descalant Cleaner
  • ·       Inhibited Sulfamic Acid Boiler Descalant
  • ·       Boiler Online Sludge Conditioner Descalant

Replacing Sodium Hypochlorite with Double Chain QAC based Disinfectant

Replacing Sodium Hypochlorite with Double Chain QAC based Disinfectant Remember that pungent smell when mass disinfection of public places occurs. That same irritating smell you can relate to in swimming pools, and your eyes itch and redden, and your skin itches, and there is a big board saying “Chlorine in pool”, that’s hypochlorous acid, viz., when sodium hypochlorite breaks down. Sodium hypochlorite/ Hypo (NaOCl) is inorganic chlorine based liquid disinfectant, available as aqueous solutions of 5.25% - 6.15% (household bleach) or concentrated 12% NaOCl solutions. Large quantities are also used as a disinfectant in water and wastewater treatment and sanitary equipment. In food processing, sodium hypochlorite is used to sanitize food preparation equipment, in fruit and vegetable processing, mushroom production, hog, beef and poultry production, and fish processing. Typical Uses of Hypo: ·       2%: Shock Chlorination of Wells · ...

Role of Polyelectrolytes in Wastewater Treatment

  Effluent Treatment or Industrial wastewater treatment consists of mechanisms and processes which are used to treat water that have been contaminated by anthropogenic, industrial or commercial activities prior to its release into the environment. Industrial wastewater serves as one of the important pollution sources that add up in polluting the water environment. The sewage sludge produced is subjected to sludge treatment. Many problems are associated with wastewater collection and treatment such as foaming, solid accumulation, high BOD, sludge de-watering, heavy metals and offensive odour.   But such treatments are no more complicated processes, since there are chemicals that are applicable for the treatment. These chemicals follow various treatment mechanisms in various different standards, which include from chemically treating raw wastewater before discharging it into the environment, to recovering valuable resources from sludge treatment and wastewater. Conventional tr...

The Role and Importance of Demulsifiers in Oil and Gas Industry

  Demulsifier helps to extract oil and purify water, which is especially important in crude oil production and wastewater treatment.   It is a substance that separates an emulsion into components and destabilizes water-in-oil emulsions. In Crude production, Water-in-oil emulsions are typically produced, owing to the presence of emulsifying agents such as surfactants, slits, fine solids, drilling mud, clay, water, and other impurities. These impurities are undesirable need to be removed which would otherwise shackle the quality of the crude.   How does It work? Demulsifier consists of two liquids that are not mixed with each other and tiny droplets of one liquid are evenly distributed throughout the volume of the other. This kind of liquid is called dispersion medium, and the droplets are called dispersed phase. During the demulsification process, a demulsifier accumulates on the surface of the droplets and groups them together.   The process of separating a...
