The range is a combination of a polymer and an organo - inorganic formulation to keep cooling water system free from scaling & corrosion & micro bacterial growth. |
| Corrosion inhibitors : A blend of various chemicals that protect metal from different types of corrosion & the formulation ensures rapid & complete reaction of oxygen scavenging. |
Corrosion inhibitors : A blend of various chemicals that protect metal from different types of corrosion.
Anti-scalent : These are polymeric formulations designed for increasing the solubility of calcium & magnesium. They prevent the deposition of hard scales due to hardness causing salts and do not allow that scales to attach to the metal surfaces. hence heat transfer surface is kept clean. With the help of these formulations cooling water system can be operated at high COC with minimum blow down.
Dispersant : The blend of powerful dispersants and penetrates along with surfactants that loosens and removes existing deposits from the system |
|  Sludge conditioners : Sludge conditioner alter the properties of this sticky sludge in order to prevent scaling on the boiler tubes and easy discharge of these sticky material during blow downs.

ParaLine- X –FIRESIDE TREATMENT CHEMICAL |
| A perfect blend of Para conditioner for different industrial Paras i.e. F.O, LSHS, LDO, HSD etc. Which helps you to keep your system clean , better efficiency of boiler , less corrosion etc. |
ParaLine-X is a formulation which contains dispersants, chemicals & corrosion inhibitors. It is a free flowing powder, non toxic and safe to handle. It is to be dosed directly into the furnace while the combustion equipment is in operation |
| Keeps Para System Clean : A polymer dispersant which disperses sludge In line particles. The detergent action of the polymer keeps oil heaters, strainers and burner nozzles clean. This results in efficient use of the equipment
Better Para Atomization : The surfactant atomizes Para improving combustion. This allows operation at lesser excess air, improving combustion efficiency. |
ParaLine-X when enters a high temperature zone it vaporizes and forms a thin film on the comparatively cooler surface of the furnace the combustion catalyst reduces ignition temp. of the adhering carbon permitting to burn at reduced temperatures. Oxidizing agents provide the combustion oxygen.
ParaLine–X keeps the equipment at the peak efficiency while traditional cleaning methods cause a sharp decrease in efficiency & increase in stack temperature between shut-downs |
| Catalytic Combustion : Reduces ignition delay of asphaltic components in Para & helps to burn it completely reducing Soot & clinker formation. |
|
ParaLine-X exposes the bare metal of the heat exchanger. The corrosion inhibitors protect the metal from corrosion by acids produced during combustion & prevent scale formation due to metal oxidation |

 Improving Your Boiler Efficiency & Reducing Energy Costs
Each process house spends between 60 Lacks to 100 Lacks a year on Boiler & Thermopak fuels. Most of the boilers run on very low efficiencies due to various losses. A detailed boiler efficiency calculation & various losses involved are given in appendix 1 & appendix 2.
Out of these the boiler losses which can be be easily reduced are :
-
Surface Radiation losses : can be reduced by checking & redoing the insulation on the boiler. These losses should be less than 2%.
-
Dry Flue Gas (Stack) losses : When solid Paras like Lignite, Coal & Bagasse are used, solid fouling deposits are formed on the fireside tubes of the furnace. These deposits prevent the heat to be transferred to the fireside tubes & hence the heat is instead lost to the stack chimney. A 20 mm slag deposit can increase the Para firing rate by as much as 6%. These losses can be practically confirmed by measuring the stack temperatures & using the efficiency equation in the appendix 1. A drastic increase in stack temperatures by more than 25 – 30oC will be observed in most cases. This further leads to production losses by frequent shutdowns to clean these slag deposits. Besides these deposits also cause corrosion of the tubes due to the presence of Sulfur & Vanadium.
-
Unburnt Carbon in Ash Refuse Losses : More than 8% Carbon is lost in ash due to clinker formation & incomplete combustion of the coal.
Solution: Thermax Ltd. has developed state of the art Para additives viz. Thermomix C (for Imported Coal) & Thermomix BGL (for Lignite & Bagasse) to eliminate all of the above mentioned Para related problems. They help n reducing energy costs as well as reduce preventive maintenance. As seen in Appendix 1 & 2, these products can improve the boiler efficiency considerably by more than 5 – 6%.
-
Blow Down Losses : As seen in the appendix 3, even a softened tanker feed water has a high TDS of 800 – 1000 mg/l. This amounts to a huge blow down loss of 25% if the recommended boiler drum TDS of 5000 mg/l to be maintained. Even S.M.C. water which has a TDS of 300 mg/l, would mean that Blow down losses would be considerable at 6.4%.
Reverse Osmosis plant or D.M. plant can reduce these huge losses to to less than 0.5% as shown in the appendix 3. This in terms of monetary savings per year can be more than 7.5 – 10.5 Lacs for Solid Paras & as high as 14 Lacs if the boiler is Natural Gas fired. Thus payback period for an R.O or a D.M. plant is less than a year.

| PARTREAT - 801 Prevention of corrosion in JetDyeing Machine |
|
| |
Problem :
Moderate to severe corrosion of Stainless steel material has recently been observed in many Jet Dyeing machines. This is experienced as highly problematic pitting & abrasion of the steel surface, which results in pulling of the fabric threads & pilling & damaging the feel of the fabric. If this corrosion is unchecked, this continuous corrosion over a period of time, causes steel failure & even serious accidents. In fact 50 Jet Dyeing machine explosions have occurred in Surat in the last five years.
The main causes of Jet Dyeing corrosion are :
-
Usage of inorganic acids like Hydrochloric acid, acid substitutes. In few mills these substitutes were found out to be corrosive cocktails of mixtures of Sulfuric & Phosphoric Acid!!
-
High TDS of water, especially the high Chlorides & Sulfates concentrations in water itself causes severe corrosion even of SS 316.
Corrosion of various S.S. under the influence of various acids, is attached herewith. ( Reference – Perry's Handbook for Chemical Engineers )

| Paracid W : is an excellent eco-friendly substitute for Acetic Acid, Formic Acid, Citric Acid & Tartaric Acid used in dyeing, printing & Padding operations of Disperse Dyes on Polyester. Acetic Acid, Citric Acid & Tartaric Acid have very high COD, BOD, which pollute the environment. Paracid W is an eco-friendly option which has much lower COD, BOD & hence reduces your environmental pollution loads at source. |

Above all Paracid W gives the desired pH of 4.5 – 5.5 with almost 40% lower quantities of Acid, with the same depth & brilliance of the other two acids.
Application : Use 40 – 50% of Paracid W in dyeing, printing & finishing to get the desired pH of 4.5 – 5.5. The concentration would depend upon the printing gum, water alkalinity & other additives.
Appearance : White crystals.
Packing : 25 / 50 Kg Bags.
Pretreatment of fabrics is essentially the most critical stage in any textile wet processing industry. Scouring of fabrics is one of the stages in the pretreatment cycle.
ParaScour Stain XM is a strong wetting cum Stain Removing, Scouring & Emulsifying Auxiliary. The unique combination of choicest emulsifiers & surfactants ensures that dirt & grease are efficiently removed from the fabric & held in the liquor bath; i.e. not allowing redeposition of the dirt & grease onto the fabrics.
Properties :
Appearance : Pale Yellow Liquid
Chemical Appearance : Non Ionic
pH : 7.0
Stability : Excellent Stability with water to any extent.
Scouring & Stain Removal : In the scouring of cotton fabrics, polyester fabrics, ParaScour XM provides extremely good results.
For Cotton Fabrics : – 0.5 – 1.0% owf is recommended.
For Polyester Fabrics : 2 – 2.5 gpl at 80oC – 120oC for 30 – 45 minutes.
