Propylene glycol is used as antifreeze agent and industrial coolant in different industries where contamination with food is possible, de-icing solutions etc. Propylene glycol is generally regarded as safe for use in food. It is used in the industries like food, beverage etc for heat transfer, also used in vehicles. Antifreeze Coolant should be efficient in transferring the heat as well as preventing scale and corrosion.

Propylene glycol [HO-CH2-CH(OH)-CH3] is pronounced as pro'puh-leen-gly'col. It is a clear, colorless, slightly syrupy liquid at room temperature. The compound may exist in air in the vapor form though it must be heated or briskly shaken to produce a vapor. It is actually a multi-variant chemical compound. Propylene glycol - in an industrial cooling and heating process terminology is referred as industrial coolant or heat transfer fluid (HTF) or the common fluid that is used in large installations for transporting heat from one place to another.

Features :

• serves as a solvent
• offers outstanding stability with high flash and boiling points
• reduces the freezing point
• increases the boiling point
• helps to bind and transport other substances (excipient)
• holds and dissolves active ingredients equally in a medium
• connects and stabilizes insoluble fluids (emulsifier)
• attracts/holds water/moisture (hygroscopic)
  

Usage :

• As an emulsification agent in Angostura and orange bitters
• As a moisturizer in medicines, cosmetics, food, toothpaste, shampoo, mouth wash, hair care and tobacco products
• As a carrier in fragrance oil
• To produce polyester compounds
• As a base in deicing solution
• In smoke machines to make artificial smoke for use in firefighters' training and theatrical productions
• As a solvent for food colors and flavorings
• As an ingredient, along with wax and gelatin, in the production of paintballs
• As a wetting agent, used to determine drying time in paints and coatings
  

A non-toxic substitute of Ethylene Glycol :

Propylene Glycol is the replacement of Ethylene Glycol in newer automotive antifreezes and de-icers in aircrafts. Like Ethylene Glycol, Propylene Glycol also has the special physical characteristics of depression of freezing point when mixed with water. It happens due to disruption of hydrogen bonding. Pure water freezes at 0OC. But aqueous solution of Propylene Glycol (10% by weight) has a freezing point of -3OC. 30% by weight aqueous solution of Propylene Glycol freezes at -12OC and a 60% by weight Propylene Glycol and water mixture can further lower down this freezing point to -51OC.

Why Glycol turned into red color ?

Because of the extensive corrosion & rust in the system metal makes the glycol turn reddish in color. At this point the glycol is fouled with iron contaminants that increase the glycol degradation rate. It is important to add corrosion inhibitor to the glycol system to avoid such degradation of glycol.

Application Areas :

Beverages & Juices, Breweries & Distilleries, Packaged Food Freezing, Canneries & Preservers, Fish Processing Units, Pharmaceutical & Bulk Drugs, Poultry Processing Industry, Thermal Storage System, Heating and Cooling Systems, Snow Melting and Refrigeration, Ice Skating Rinks, Vegetable Oil Industry, Ice Manufacturer, Cold Storage Systems etc.

Product Physio-Chemical Data :

• Form and Appearance - Clear, colorless liquid
• Assay as Propylene Glycol - 99.8%
• Specific Gravity - 1.04 (approx.)
• Molecular Wt. -  76.0548 gm/mol
• Solubility in Water - 100%
  

Handling Measures, Precaution & Storage :

Propylene Glycol is slightly hygroscopic & the storage temperature is not critical, it must be stored under conditions so that contamination with water and adsorption of moisture are prevented. It should be noted however for product quality reasons the storage temperature should not go above 40°C. At below freezing temperatures the product viscosity might become too high for transfer from the storage containers with the pumps available. PG is a stable chemical and is not expected to deteriorate significantly with time provided if it is stored as indicated. The drums should be stored in dry condition, better to use the original drums rather than the other drums and if the drums are opened then it must be closed tightly at unused situation. The chemical can be stored up to 6 months. 

A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool air or equipment as required.

Cooling towers are heat removal devices used to transfer process waste heat to the atmosphere. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near the dry-bulb air temperature.

Biocides and MicroBiocides are chemicals that prevent and eradicate unwanted biological fouling from the system. Biocides are of various nature such as oxidizing, non-oxidizing, cationic, anionic etc. Biological Fouling or Biofouling is the undesirable accumulation of micro-organisms, algae and diatoms, plants, and animals on surface, pipelines and heat-exchangers of cooling systems. Bio-fouling can be of aerobic (that require oxygen) or anerobic (that don't require oxygen) organisms. In general the former is found in Cooling Towers and the later in closed circuit systems.

Another very important reason for using Cooling Tower Micro Biocides in cooling towers is to prevent the growth of Legionella, including species that cause legionellosis or Legionnaires' disease, most notably L. pneumophila, or Mycobacterium avium. The various Legionella species are the cause of Legionnaires' disease in humans and transmission is via exposure to aerosols—the inhalation of mist droplets containing the bacteria. Common sources of Legionella include cooling towers used in open recirculating evaporative cooling water systems, domestic hot water systems, fountains, and similar disseminators that tap into a public water supply.

Micro biocides function in eradication of sulfate reducing bacteria, aerobic and anaerobic bacteria that are formed and found in Cooling Tower Water.Micro Biocides are very vital for Closed and Open Circuit Cooling Water Treatment.

TCF (Totally Chlorine Free) micro biocides are compatible with heat transfer fluids (HTF) and can be used without any fear of corrosion of chlorine addition to the system or depletion or degradation of HTF and corrosion of PHE (plate type heat exchangers)

Chemtex’ s Closed loop Micro biocide surpasses the performance of other such less effective closed loop treatment chemicals (such as Nalco 7330, Nalco 77352NA etc.)

Orange Colored Inhibited Ethylene Glycol is used as heat transfer agent in food, beverage or brewery industries, there lays a possibility of contamination even though Ethylene Glycol is harmless to our health up to a certain level. But to keep ourselves on the safer side of the problem, something has to be done to detect the leakage of Glycol from the system. But we are fortunate enough that it had already done. Chemtex’s offered a perfect blend of Inhibited Ethylene Glycol and a colored leak detecting media. This media turns the Glycol solution to blue or orange or red colored solution. So, whenever there is any leakage from Glycol systems, it will be visible during the daylight and even in the night time due to its color.

Handling Measures, Precaution & Storage:

• Orange colored Inhibited Ethylene Glycol is toxic and must be handled with all necessary precautions. Proper human safety products such as Splash goggles, lab coat, vapor respirator, gloves and boots should be worn while handling and applying chemicals.
  
• Splashes on skin should be washed off with water immediately. In case of splashing into the eyes, flush it with fresh water and obtain medical attention. It should not be injected.

Chemtex’s MEG Corrosion Inhibitor is a specially formulated chemical additive designed to prevent corrosion in multi-ways. It treats the surfaces of the metal making them less susceptible to corrosion. It buffers the organic acids formed as a result of glycol oxidation. Inhibited glycol based heat transfer fluids provides corrosion protection without reducing system’s heat transfer efficiency.

It is very important to use inhibitor in glycol system to prevent degradation of glycol. Glycol in presence to heat and air degrades into five organic acids namely: Glycolic Acid, Glyoxalic Acid, Formic Acid, Carbonic Acid & Oxalic Acid. Metal acts as catalyst in un-inhibited glycol solution for the formation of these acids, which then chemically attacks and corrodes system.

Also available Pre Inhibited Mono Ethylene Glycol and normal Mono Ethylene Glycol.

Metal acts as catalyst in un-inhibited glycol solution for the formation of these acids, which then chemically attacks and corrodes system.

Glycol turns Red. What does this indiate?        Due to the high corrosion in the HTF system, the rust in the system metal makes the glycol turn reddish in colour. At this point the glycol is fouled with iron contaminants which increase the glycol degradation rate. It is very important to add corrosion inhibitor to the glycol system to avoid such degradation of glycol.
