No natural gas infrastructure? LPG cleans up heavy-fuel power generation

The value of water can often not be expressed in price, especially in regions where water is a scarce asset. Learn more about Heat ReCycle in our webinar.

Liquefied petroleum gas includes various mixes of mostly propane (C3H8) and butane (C4H10) and other hydrocarbons in small concentrations. It is a suitable fuel for power plants where natural gas for various reasons is not available.

Several Siemens industrial gas turbines can already burn 100 percent propane in standard natural-gas DLE combustors, and recent combustion tests on the SGT-300 have shown that even butane-rich LPGs can be considered for the standard combustors.

There are a number of reasons for the increasing popularity of LPG for power generation:

*         LPG is a cleaner fuel than heavy fuel oil (HFO) or diesel

*         LPG is traded as a commodity worldwide

*         Transportation is easy by sea, rail or truck, regardless of batch size

*         Storage of LPG is relatively simple and does not require cryogenic storage tanks

*        Storage and distribution infrastructure for LPG is readily available in many countries as it is used for transportation, in           industry and also small-scale heating and cooking.
