Antiscalant Dosing with Chemtex Chemicals

Scale and Corrosion is considered a curse to all industries, be it large or small.

Due to their subjection to water systems, heavy metal installations, industries face a huge annual loss due to these complications as they have direct implications on the production rate and outcome. Formation of scales cause severe metal lining problems, decrease in fluid flow rate, pitting and perforation, pore throats, wear and tear, machinery failure and primarily first stage of corrosion (in most cases).

Antiscalant dosing is preferred over other conventional treatments in counteracting scaling and corrosion. The primary reason being its simplicity and effectiveness over particulate matter deposition and cost efficiency. Most antiscalant chemicals work on adsorption mechanism, where they get adhered to the surface, preventing any interaction between inorganic salts and surface lining, ensuring lesser accumulation, lesser precipitation in the feeding solution, and ensuring prolonged protection.

Chemtex Antiscalant Chemicals can be directly dosed into the feeding system, and reduces the usage of acid usage. The exact dosage rate varies depending upon the severity of scaling, and typical OEM recommendations.

The composition and physico-chemical nature is tailor made to suit the specific nature of the problem enquired. Depending upon a number of co-related factors that help improve the workability of the system, also inhibiting the accumulation of inorganic salts that forms scales. Common compounds that are used in formulating an antiscalant are polyacrylic acids, polymaleic acids, organophosphates, polyphosphates, phosphonates, anionic polymers, etc.

The most likely mineral contaminants that poses threat to any metallic system are Calcium carbonate, Calcium sulphate, Strontium sulphate, and Barium sulphate.

• Boiler Antiscalants are multi-purpose heavy-duty chemicals designed to remove rust, hard deposits of water scale, iron oxides, oily contaminants, lime and greasy deposits from boiler systems. Regular usage of these chemicals provide protection to system metallurgy, ensuring an optimally longer boiler life cycle.
• For Reverse Osmosis systems, various formulations were evolved depending upon the type of membrane, quality of feed water and rate of product recovery;
  • Use of high pH RO antiscalants to inhibit scales and disperse colloidal particles in cellulose acetate and thin-film membrane separation systems, stable over a wide range of supersaturated salt solution. It prevents precipitation on the membrane surface, reducing the risk of scaling and helping in effective plant operations with optimal recovery rate.
  • Neutral RO antiscalants reduces membrane fouling within separation systems, effectively controlling inorganic salts, metal hydroxides, and colloids in RO feed water
  • Application with low pH antiscalants eliminate inorganic scales in multiple applications areas. It stabilizes metal ions to prevent metal oxides precipitation and disperses silt and clay particles.
• Thermal Desalination Antiscalant, new formulation is precisely formulated in order to provide excellent control of scaling & fouling. On regular application, it ensures reduced cleaning frequency and thorough cleaning.

 General Key Features & Benefits:

• Excellent cleaning efficacy
• Wetting agent for scale penetration
• Excellent removal of oil and grease
• Inhibitor package to prevent corrosion
• Excellent de-rusting

Chemtex Speciality Limited manufactures a wide range of antiscalant chemicals used for the purpose of deterrence of scaling and elimination of inorganic deposits over a broad spectrum application.

Hybrid Organic Acid Technology (HOAT) Coolant

Optimal use of machines is directly proportional to its engine performance.

What an engine does is it converts the supplied energy into its mechanical form, driving the machine to work. Engines require one-third of total heat that is generated during conversion and the rest of the heat is needed to be evacuated from the combustion chamber which would otherwise lead to engine failure.

Earlier, water was preferred as an ideal coolant for quite a period of time but the problem started to arise when the temperature would become extremely high or low, to be precise temperature more than 100°C and below 0°C. To get rid of this problem, coolants were formulated. Coolants are categorized chemicals that increases the boiling point of the fluid and decreases the freezing point of the fluid to make it suitable for use in extreme heat and freezing conditions.

Coolants are a proportionate mixture of antifreeze and solvent, mainly glycol and water. Ideally utilized as a preventive in a device from overheating due to its high boiling point and low freezing point property, these chemicals are indulged with anti-corrosive, anti-scaling, and anti-microbial properties, protecting the same from the adverse effects extremely low as well as high temperatures. The coolants are processed with latent heat addition, improvising the cooling efficiency of the same. Coolant Additives are mostly utilized in automobiles, machines, HVAC and various other industrial processing.

Considering the variety of utilization and applications, two new types of coolants are used in most of the HVAC engines are:

• OAT Coolant: Based on Organic Acid Technology, OAT coolants are free of silicates and manifests provides excellent protection to aluminum at high temperature.
• HOAT Coolant: Hybrid Organic Acid Technology is based silicates free, nitrates free and borates free formulation, incorporated with OAT technology which are suitable to be used in HVAC as well as less combusting application. The HOAT package is uniquely designed to protect aluminum, brass, copper, solder, steel, cast iron, aluminum alloys and other components such as rubber hoses, gaskets, rubber seals, and elastomers commonly found in the engine radiator.

The HOAT Coolant Additives also help the industrial equipment to produce superior performance by rendering them protection from metal sludge and scale deposits and any contamination in the radiator. Corrosion Inhibitors are nowadays used in the composition of these Coolant Additives during processing so as to ensure perfect protection to equipment from corrosive attack.

Using HOAT coolant in engines and radiators ensures following benefits:

• Extended operational life for heating and cooling systems
• Excellent anti-corrosion and anti-scaling properties
• Higher stability compared to normal coolants; Does not get reduced with time
• Prevents pitting corrosion
• Prevents the fluid to get over heated, showing effective control on fluid temperature be it high or low
• Lower environmental impact
• Excellent compatibility with Aluminum, Rubber and Elastomers
• Non-foaming
• NAP free Coolant

Chemtex Speciality Limited is an esteemed manufacturer of HOAT type coolants, recognized by world class organizations all over the world. Visit us at http://www.chemtexltd.com/products-and-solutions/heat-transfer-fluids/

 

Rodine 103 serves to enrich the strength of pickling acid bath

Rodine 103 serves as an effective inhibitor for phosphoric, hydrochloric, acetic, sulfuric, oxalic, sulfamic, citric, bisulfate, and other organic acids. It manifests as a liquid inhibitor that has been specially designed to be used in industrial cleaning operations for helping in the prevention of acid attack on brass, copper, mild steel and stainless steel. Rodine 103 helps in the enrichment of strength of pickling acid bath and thereby reduces acid consumption. It exhibits efficient fume suppression and on account of its excellent wetting properties it provides for better cleaning.

Rodine 103 may be administered either in diluted form or concentrated form of the hydrochloric acid but for all other acids Rodine 103 must be added in their diluted form. For proper cleaning of equipments, the dilute acid synergized with Rodine 103 is required to be circulated throughout and if this circulation cannot be attained, the equipments are filled with inhibited acid solution for a specific duration with the intention of removing the scales and deposits. Heating of acids or equipments can be carried out to accelerate the operation prior to cleaning. The factors that contribute to an efficient cleaning by Rodine 103 depend on the acid being used, temperature of the cleaning bath and the type of metal surface of the equipments.

Rodine 103 helps in modifying the metal surface to aid in the prevention of corrosion. It exhibits superior wetting properties that accounts for better cleaning efficiency. It carries out effective fume suppression and helps in the reduction of metal loss. Rodine 103 serves to enrich the strength of pickling acid bath and reduces acid consumption.
