5.9 LPG Loading Application Overview
Fusion4 MSC-L supports Liquefied Petroleum Gas (LPG) road loading.
Liquefied petroleum gas or liquid petroleum gas (LPG or LP gas), also
referred to as simply propane (C
3
H
8
) or butane (C
4
H
10
), or a mixture of
those 2 propane and butane are flammable mixtures of hydrocarbon
gases used as fuel in heating appliances, cooking equipment and
vehicles.
MSC-L also supports loading a blend of propane and butane which may
be required over changing climatic conditions. A typical blend can
include 60-70% butane and 30-40% propane along with additives
(odorants like ethanethiol,l ethyl mercaptan) for leak detection. LPG has
a boiling point that depends on the vapour pressure, the temperature
and the composition of it. LPG evaporates quickly at normal
temperature and pressures so it must be kept pressurized, and a MSC-
L device helps you to control the vapour pressure.
FIGURE 5-23 Application overview - LPG loading
The pressure in the delivery line is monitored/controlled to be above the
vapour pressure to avoid LPG vaporization and, where possible, to
optimize truck loading time. Fusion4 MSC-L supports configuration with
independent external “back pressure” regulator valve (not shown) as
well as configuration where the “normal” flow control valve (DCV) is
used to prevent from LPG vaporizing by reducing prescribed flow rate
when pressure approaches vapour pressure.
