General Characteristics
Propane-butane is a mixture of liquefied hydrocarbons, mostly with three to four carbons in the molecule. Liquid propane-butane is a colourless liquid, easy to evaporate, and of specific odour.
Basic Quality Parameters
CSN 656481
| Quality Requirements | Summer | Winter |
|---|---|---|
| C2- hydrocarbons and inerts - %, max. | 7 | 7 |
| C3- hydrocarbons - %, min. | 30 | 55 |
| C4- hydrocarbons - % | 30 - 60 | 15 - 40 |
| C5- and higher hydrocarbons - %, max. | 3 | 2 |
| unsaturated hydrocarbons - %, max. | 60 | 65 |
| Hydrogen sulfide - mg.kg-1, max. | 0,2 | 0,2 |
| Sulphur content - mg.kg-1, max. | 200 | 200 |
| Evaporation residue - mg.kg-1, max. | 100 | 100 |
C5-hydrocarbons and higher may partially or totally be replaced by C4-hydrocarbons, while sum of C4 + C5 and higher hydrocarbon content shall not exceed 63% on summer type and 42% on winter type.
Application
Propane-butane is used as fuel gas in households, chemical laboratories, industries, etc.
Packaging, Storage, Transportation
Propane-butane is supplied under pressure in rail tankers and road tankers. Propane-butane storage, transportation and handling must comply with legal regulations.
