Propane is the third compound in the series of saturated hydrocarbons after methane and ethane. Propane is a straight chain hydrocarbon without any isomers and is the lightest component of LPG and also has the highest calorific value among the LPGs. Propane is normally produced, in large quantities, from the fractionation of natural gas. Propane fractionated from natural gas contains very less sulphur in elemental form or as hydrogen sulphide. This makes propane an ideal fuel for applications which are sensitive to the presence of sulphur. The other intrinsic benefit of a low sulphur fuel is that it results in very low sulphur dioxide emissions, which are known to cause acid rain. The low sulphur footprint, besides causing lower environmental pollution, results in lower stack corrosion wherever stacks for flue gases are provided, thus resulting in maintenance savings.

However the real advantage of propane over LPG stems from the fact that, it is composed largely of only one type of molecule. As a result, the combustion system can be optimally tuned in terms of air-fuel ratio, due to which you get the best thermal efficiency (the stoichiometric ratio for propane:air is 1:24). Besides on a unit weight basis, propane has a higher calorific value as compared to butane by about 2%, which is an added bonus when compared to LPG.

The higher efficiency in burning propane results in combustion gains which help to reduce your fuel bill. This contrasts with LPG which consists of propane & butane mixtures which require differing amounts of air:fuel ratios. This makes it relatively more difficult to tune the combustion system for the potential optimal efficiency. Due to this inherent advantage of propane, temperatures can be accurately controlled in combustion applications using propane.

Besides combustion applications, propane is used extensively in petrochemical industries as a feedstock. Of late, use of propane as a feedstock in purpose built propylene production plants based on PDH* technology, is gaining popularity due to its price advantage over naptha.

Totalgaz marketed propane is derived from natural gas. Totalgaz has developed core expertise in installing propane systems. It should be borne in mind that propane systems are compatible with LPG systems and not the other way round as propane is lighter and has a higher vapour pressure.

As Propane boils at -43°C, it results in faster evaporation at ambient conditions, a characteristic often valued in small LPG installations.

Totalgaz markets propane in Bulk as well as packaged forms through their Quantaz-ProTM systems, making it the only company in India to do so.

*PDH : Propane Dehydrogenation is the latest technology in which a C-H bond is replaced with a C=C bond using catalysts and is rapidly gaining popularity the world over.
