Odour Control

August 4th, 2013 by

Most “odour neutralisers” on the market today do not actually neutralise any odours; they merely mask them by trying to trick the olfactory senses by overlaying one odour with another.

This is exactly what most people do when they buy a can of “air freshener” from the supermarket and put it in the bathroom. When it is used, often the resultant mixture of smells is worse than the original. Masking odours that are offensive to humans and animals may control the odour immediately and for a very short period of time, however, this does not remove the hazardous and sometimes deadly nature of the compound.

Air Repair is an odour neutraliser that removes the odourous compounds by chemically reacting with the offending odour.

This reaction changes the chemical structure of the compounds and changes it into a non-volatile, readily disipatable amine (salt). Because this reaction changes the structure of the offending compounds, it is no longer odourous. “Air Repair” is made from food and cosmetic-grade compounds, is non-hazardous and biodegradable. “Air Repair” is made in two specific formulas: 7D-A and FS GOLD. 7D-A targets alkali odours (Ammonia, Trimethylamine, etc.) and FS GOLD targets acidic compounds (Hydrogen Sulphide, Methyl Mercaptan, Sulfur Dioxide, etc.). While these are the main types of odours, FS GOLD also works exceptionally well on gases such Benzene, Toulene, Ethylbenzene, Xylene (BTEX), Naphthalene and other Polycyclic Aromatic Hydrocarbons (PAH’s).

“Air Repair”© products are different than nearly all other odour neutralisers or masking agents. The difference lies in the product makeup: nearly every product in the market is a blend of essential oils or plant extracts combined with a standard surfactant while “Air Repair”© products are made of food and cosmetic grade compounds and contain only 1% essential oils or plant extracts (by total volume of concentrate). Basic chemistry proves all essential oil and plant extract based products cannot truly neutralise odours; they can only mask them or encapsulate them for a period before releasing them again.. Essential oils and plant extracts cannot bind to, and react with, a compound such as NH3 and change the structure of that volatile compound into a non-volatile compound.

Air Repair 7D-A

This was developed to neutralise the alkaline odorous compounds of Ammonia, Butylamine, Trimethylamine, other Amines, Skatole, VOC’s and all other compounds of a similar nature. These types of odours are associated with chemical and industrial processing and their wastes (solid and liquid), putrecible waste (household garbage), sewage treatment plants and the extended reticulation system, all animal breeding and processing facilities, and most types of industrial waste. By spraying on a timed programmed basis all odours can be eliminated.

The alkaline odorous compounds react with “Air Repair” 7D-A and are neutralised of their toxic and offensive potential. A typical reaction can be shown in the following equation: NH3 (AMMONIA) + “AIR REPAIR” 7D-A = CH3COONH4 (AMINE SALT) or RCH2COONH4.

This is a non-volatile Amine, therefore has no odour and is readily absorbed.

Air Repair FS GOLD

AIR REPAIR© FS GOLD was developed for the strong acid odours, mainly Hydrogen Sulphide, Methyl Mercaptan and other gases, associated with sewage and fatty wastes. AIR REPAIR© FS GOLD has added to it, an emulsifying agent, which helps with the dispersion of scum and oil and reduces fat build-up on plant and machinery and considerably reduces maintenance costs and prolongs equipment and infrastructure life.

It is important to note, acidic odours, regardless of origin, can be neutralized using AIR REPAIR© FS GOLD.

The neutralization of Hydrogen Sulphide can be shown in the following equation: H2S (HYDROGEN SULPHIDE) + AIR REPAIR© FS GOLD = RNH3SH (AMINE-BISULPHIDE SALT).

This is a non-volatile Amine, therefore has no odour and is readily absorbed.

AIR REPAIR© FS GOLD is also used in industries where hydrocarbon odours are a problem. Specifically, odorous compounds such as Benzene, Toluene, Ethyl benzene, Xylene, Naphthalene, and PAH’s (Polycyclic Aromatic Hydrocarbons). Examples of these types of industries are oil refineries, bitumen manufacturing for use in tar sealing roads, refining of natural gas, and contaminated soil remediation.
