NALCOOL 2000 - Automobile Coolant Corrosion Inhibitor

Corrosion and scaling in automobile cooling systems is primarily by chemical reaction of oxidizing agents in the coolant on the metal components. The type and nature of materials present at heat exchanging surfaces, the temperature of the system, pH and type of corrosive elements present in the coolant determine the type of inhibitor package needed.

Conventional water based coolants constantly need additives in the form of mineral inhibitors such as phosphates, nitrites and borates for poplar heat exchange surface metals like aluminium, copper etc along with other parts made from cast iron & mild steel. Absence of suitable inhibitors can cause corrosion, metal cavitation, scaling and cause leaks by destruction on rubber gaskets and head caps. Liquid coolant additives serve ideally as easy to use blends that can be directly mixed with coolant water for easy and quick anti-corrosive action on coils, coolant pump and radiator fins.

Corrosion inhibitors are generally blends of chemicals added to the coolant water to reduce material loss and system damage due to oxidation. The prerequisite is a passivation agent to coat the metal surfaces preventing further corrosion followed by neutralization of oxidizing ions in the coolant thus reducing cavitation. Best corrosion inhibitors need to be fast acting and thermally stable so as to operate at high temperatures and high coolant flow rate. Nitrite, Borate, Silicate and Polyacrylate formulations seem to be the most popular as corrosion and rust inhibitors. This is due to the fact that they are able to remove most oxidizing agents in common coolants while passivating metal surfaces for a long lasting corrosion control. The only requirement is to keep a steady inhibitor concentration in the system.

NALCOOL 2000 manufactured by Nalco Company is a synergized inhibitor blend for metal passivation and sale suppression as a water soluble corrosion inhibitor.

NALCLEAN 8940: HCL Based Cleaner For Food Processing Industry

Food Processing, beverage and dairy industry have recently shown a major interest in Clean-in-Place processes due to increased demands from customers in CIP verification and improvements in hygiene standards, product quality shelf life and microbiological consideration. While microbial contamination requires use of sanitizers and disinfectants, pre-processing like pasteurization etc, removal of mineral scaling, food layering and organic depositions can be easily met with cleaning solutions specifically designed for the purpose.

CIP involves the jetting of surfaces or circulations with an appropriate cleaning solution under increased turbulence and flow velocity.  Cleaning solutions so chosen should be active at contaminant removal from any and all types of surfaces without being corrosive to the materials themselves, non toxic and non-residual formulations that can be easily washed off and do not create issues with ultimate quality of food products produced. CIP easily shortens time for cleaning and often cleaning solutions are recoverable. When incorporated in automatic systems, they allow safe and reproducible results that are economic and product friendly.

The simplest form of non-toxic cleaners are basically blends of mineral acids and inhibitors. Acid circulation and spraying is effective in removal of encrusted proteins and mineral deposits on heat treatment surfaces.  Hydrochloric acid seems to be the easy and convenient choice for CIP processes owing to its quick action and high solubility. It can be used directly to clean or as a neutralizing solution after alkaline wash. It enhances draining and drying of pipelines, better bacteriostatic action and removal of mineral deposits like hard water scale, milk stone, beer stone etc. Typical concentrations in solutions range from 30%-70% that require appropriate dilution before application based on industry, equipment, nature of contamination, topography of surfaces to be cleaned and application methods.

NALCLEAN 8940 is a hydrochloric acid based acid cleaner. Manufactured by Nalco Company, it is a blend of Hydrochloric Acid (30%-60%) as a low foaming cleaning liquid that is slightly brown in color.

Metal Pickling: Acids and Inhibitors

Hot rolling processes associated with various metal industries often leave behind inorganic oxide residues on treated metal surfaces. Exposure to moisture also results in rusting of Ferro-Nickel based metal parts. These oxides interfere with further cold processing like polishing, electroplating, painting or enameling. Rust and scale formation is a thin layer of metal oxide on the surface that is mostly removed by chemical cleaning also called “Pickling”.

Pickling is carried out on oxide scaled surfaces of metals with alloy content less than 6%. The ideal pickling solution, known as Pickle Liquor is a 3%-10% solution of Hydrochloric acid (HCl) or Sulfuric acid (H₂SO₄). Hydrochloric acid is chosen over Sulfuric acid because of faster pickling action all the while minimizing base metal loss. It restricts formation of smut and greatly decreases the risk of excessive attacking.  It is also economic as heating expenses needed for sulfuric acid are spared due to possibility of lower temperature pickling.

Metal pickling is essential for thoroughly removing scales and inorganic surface contaminants before applying finishing layers like paint, galvanizing and polishing. The result of the process depends on the type, strength and temperature of the pickling liquor. In order to be economical, it is chosen as a continuous cleaning process by mode of manual/mechanized spraying or dipping in large acid vats. For small scale industries like jewellery making and research laboratories, extensive use of pickle pots is observed. Nevertheless, the corrosive action of diluted pickle acids cannot be ignored. In most cases, there is a significant loss of base metal during cleaning operations. For this reason, Acid Inhibitors are used with the acid solution to reduce base metal corrosion.

Inhibitors are natural or synthetic organic compounds added to acid solutions to reduce metal surface corrosion. They slow or stop the chemical action of acid on the base metal surface.

Inhibitors are essential to:

   Reduce base metal loss

  Protect the surface from pitting attack by excessive pickling or from poor surface condition quality

  Reduce fumes resulting from excessive acid-metal reactions

  Help economize acid consumption without reducing descaling efficacy

  Control the rate of pickling

Rodine Acid Inhibitor is a series of acid corrosion inhibitors designed to serve worldwide standards for acid inhibitors. They are specially synthesized to provide protection to base metals from acidic corrosion effectively. Rodine Acid Inhibitor products inhibit the corrosion of metals against acids like Hydrochloric, Hydrofluoric, Sulfuric, Phosphoric, Sulfamic, and organic acids blends. The most common products underlined in this range include Rodine 213, Rodine 213 Spl, Rodine 31A, Rodine 103, Rodine 103 NF, Rodine 92B, Rodine 130, and many more.

The process is limited to oxides and inorganic scales and contamination by soils, oil, grease, soaps and lubricants need additional processes with the use of Degreasing chemicals. Other limitations of acid pickling include difficulty to handle products because of their corrosive nature, the issue of hydrogen embrittlement popularly associated with some alloy and high-carbon steels, occupational hazards as the reactions produce toxic fumes in the factory shed. To obtain desired descaling, without endangering metal surfaces, acid concentrations and solution temperature need to be monitored quite strictly. Sludge is the ultimate waste product of acid pickling. It contains acid rinse water, metallic dissolved and suspended salts, waste spent acid etc. EPA considers it Hazardous waste and recommends proper treatment before disposal mostly in the form of Lime neutralization.

RODINE 213 - Acid inhibitor for Hydrochloric Acid

Most metal hot working processes tend to leave a discoloring oxide layer or scale on the surface. Deposition of inorganic impurities, stains, rust and scales from ferrous, cuprous, aluminium and precious metal mostly as oxides hinder with further processes like extrusion, rolling and galvanizing. In jewellery making, soldering and annealing processes leave metal oxide residue that prevent polishing of ornaments. Such impurities are cleaned with the help of diluted solution of acids. The method is called pickling and the workpiece is dipped in a vat of acid solution popularly called “Pickle Liquor”.

Hydrochloric acid replaced the commonly used Sulfuric acid as the pickling liquor because it pickles much faster with minimum base metal loss. The aggressive chloride ion in the acid is the key to high efficiency in the cleaning process. It is used for cleaning metals with an alloy content of 6% or less. An acid inhibitor must be added to the pickling solution to prevent the metal from dissolving or becoming pitted. Such a pickling acid solution is called “Inhibited HCL” and is a blend of Hydrochloric acid solution in water (3% to 10%) and an acid corrosion inhibitor which in itself is a blend of organic compounds that adsorb on the metal surface during pickling.

Rodine 213 is a premium organic blend of keto-amine complex substitutes with non-ionic surfactants, alcohol and solvents especially designed to inhibit attack of hydrochloric acid on metal surfaces during industrial operations like cleaning and pickling. It is effective over a wide range of metal surfaces like Iron & Steel, copper and brass. Rodine 213 is a high foaming formulation with a high efficacy at dispersing grease deposits and is ideal for HCL based pickling liquor solutions especially prior to plating.

It ensures metal surface protection during processes involving elimination of lime deposits from boiler and pipework and from evaporating plants, removal of oxide deposits from iron, steel, brass and copper. Rodine 213 is free from chlorinated hydrocarbons and heavy metals like arsenic and lead. It can be synergized with Hydrochloric acid pickling in stipulated concentrations both by circulation method and by soak and rinse method. Rodine 213’s exceptional strength and commendable heat stability makes it an ideal acid inhibitor during enhancement of the pickling process by pre-heating the equipments with the inhibited acid solution. It also acts as a strong acid fume suppressant.

Its key features can be summarized as follows:

Anionic Polyacrylamide (APAM): Industrial Wastewater Management

Industrial wastewater containing suspended organic solids pose a threat to the aquatic biota when discharged untreated in surrounding water bodies. The issue has become one of dire concern with increasing variation in nature and type of solids associated with the effluent. One promising method to treat such wastewater conveniently is using flocculants to remove the suspended solids before discharging the water. An ideal choice for this is using polymer based flocculants that are cost friendly and easy to use over a wide range of suspended solids.

Flocculation is the process by which individual particles of a suspension aggregate. They consist of anionic, cationic and nonionic polymers of varying molecular weight. They are used to increase the efficiency of settling, clarification, filtration and centrifugation operations. They adsorb on particles and cause destabilization by bridging or charge neutralization. Most common polymer used in water treatment is made from Polyacrylamide. Polymers are given anionic character by copolymerizing acrylamide with acrylic acid.

                                      

Anionic PAM series products are polymer used in water treatment that are water soluble linear chained synthesized polymers that are insoluble in other common organic solvents. They have valuable properties like flocculation, thickening, shear properties, drag-reduction and dispersibility. Thus they are widely used in environmental protection practices for the treatment of industrial wastewater containing suspended matter; mostly coarse with high concentration of positively charged particles under neutral or alkaline pH conditions.

Synthetic polymeric flocculants like APAM have become very popular in industrial effluent treatment owing to their natural inertness to pH changes, high efficiency even with low dosage, and easy handling. They are the widespread choice as waste water treatment chemicals for industries such as Iron & Steel, Electroplate factory, Metallurgical workshops, coal washing etc.

Scaling problems in RO System? Know how antiscalants function on it!

HYPERSPERSE MDC150 serves as a highly efficient Reverse osmosis antiscalant dealing with scaling issues in the RO System.

But to understand the function of antiscalants, we need to know about the Reverse Osmosis system.

Reverse Osmosis (RO) can be considered as the process in which deionization and demineralization of water takes place by making it pass under pressure through a semi-permeable reverse osmosis membrane. For filtration of heavily soiled water, using of the reverse osmosis membrane is generally accompanied by some major issues that may cause the reduction in the overall productivity of the membrane such as Degradation, Scaling, and Fouling of RO membranes.

Scaling of reverse osmosis membranes pose to be a serious botheration in the water treatment industry as it brings about the plugging off the membranes due to build up of deposited particles. Scale formation generally occur due to the precipitation of sparingly soluble salts such as calcium carbonate, barium sulphate, calcium sulphate, strontium sulphate, etc. which very commonly occur in natural water at high concentration. The clogging taking place normally due to scaling results in the decline of permeates flux, thus decreasing performance level of the process and enhancing the operation cost.

RO antiscalants, sometimes referred to as scale inhibitors, are specialized chemical formulations that are administered to increase the solubility of sparingly soluble salts. In reverse osmosis systems CaCO3, CaSO4, SrSO4, BaSO4 and CaF are the most common scales of concern. The use of such antiscalants can form an essential component in the operation of properly run reverse osmosis systems.
