Propane-air (P/A) peakshaving is an important element of peak-load management for some U.S. gas utilities. P/A is used as a supplemental energy medium with natural gas and has been shown to operate satisfactorily in most natural gas applications. The propane levels injected are compatible with the pressures (under 200 psig) and temperatures (over 40 F) found in utility distribution networks. However, P/A can create problems for natural gas vehicles (NGVs) operating on compressed gas as well as NGV fueling stations. This report contains information on P/A peakshaving and its compatibility with NGVs by documenting condensation impacts at nine conditions--i.e., three propane levels and three temperatures. These data portray the depressurization of a vehicle tank, an area selected because it illustrates NGV operation and can discriminate between acceptable and potentially non-acceptable operating points. These analyses show, not surprisingly, a correlation exists between propane level, ambient temperature, and condensation.
