Design of LHG filling stations and LHG storage terminals
LLC “Specialized Constructive Bureau” works on development of the projects
on LHG storage terminals, LHG transfer facilities (to vessels as well), gas
pumping stations and points.
A gas pumping station (GPS) is designed
for reception, storage and release of liquefied hydrocarbon gases (LHG) in road tank cars and household
cylinders, repair and re-examination of cylinders.
The need for construction of new
and expansion of the current gas pumping stations is caused by a number of subjective and objective
reasons:
Stable demand of transport and
industrial enterprises for LHG
There have been four basic sectors
of LHG application formed by now: municipal
sector, industrial sector, transport and petrochemistry. Prevalence of LHG in
each of these areas depends on a number of conditions which are very specific for
a definite region of the country. Liquefied hydrocarbon gases are chemical raw
materials used for the production of a great deal of the important products, they
are also an essential process material in a number of manufactures, for example
in a special glassworks etc. Liquefied hydrocarbon gases are widely used for the
household needs in the areas remote from gas pipelines of natural and
associated dissolved gas.
In Russia there are also favorable
conditions for the development of LHG use transport sector. As an oil-extracting
and gas country, Russia has a sufficient feedstock storage for the expansion of liquefied
hydrocarbon gases manufacture. Thus associated dissolved gas stocks (which is
one of the main raw materials for the LHG manufacture) in the Russian oil fields
make, according to the current estimates, about 1,5 billion cubic meters and
these resources are not used to the full extent at present. In the motor fuel market propane-butane is a successful competitor to motor
spirits in prices. Though now the share of propane -butane is not so great in the market, this
sphere of LHG application is rapidly developing.
Due to the increase in growth of the LHG filling stations network their owners often face different kinds of difficulties (including seasonal ones) related to the LHG deliveries to the stations. So one of the factors constraining the LHG distribution as a fuel for motor transport is the limited delivery capacity. In this connection the owners of LHG networks started to think of the construction of their own LHG storage terminals or gas pumping stations (GPS) to provide a continuous LHG delivery to the stations. The similar facilities have a number of substantial advantages as well, including an opportunity of LHG reception by any mode of transport (transferfrom rail tank cars into road tank cars).
History and priorities of gas
pumping stations development (GPS)
In 1948 at a Moscow gas plant the
first gas pumping station was
put into operation and the supply of the Moscow population with the liquefied
gas in cylinders has begun. The formation of gas supply system in other cities
and regions of the country did not start until the late 1950’s. The new era in
power supply, - replacement of black oil, peat, coal, fire wood, kerosene for
blue fuel – gas has come into existence. For the next 20 years (i.e. from the early
1960’s to the early 1980’s) almost in all metropolises gas pumping stations (GPS) of various capacity have
already been constructed.
As today consumption growth of
liquefied hydrocarbon gases (LHG)in
Russia corresponds to the global tendencies and makes about 5 % per year, gas pumping stations which have facilities
for the capacities increasing continuously expand gas sales. For example,
Rostov gas pumping station
(constructed in 1971) - had an annual sales volume up to 3 thousand tons of the
liquefied hydrocarbon gas (propane-butane). The current
gas sales rate is up to 3 thousand tons per month. For the time of gas pumping
stations and LHG storage terminals being the priorities were gradually changing.
For example, since 1988 the Rostov gas pumping station has become the first in
the south of Russia to start motor transport refitting to use a liquefied hydrocarbon
gas (propane-butane) as a motor
fuel and to fill transport with it. One of the priority directions of the Rostov gas pumping station is the use of liquefied
gas as a motor fuel for the municipal motor transport with its operation on favorable
terms. Filling stations networks extend (design works are carried out by the
LLC " Specialized Constructive Bureau "). Today the LHG rate
consumption is more than 80 % within the country, from which deliveries on administered
prices make about 15 %. Approximately 45 % of output is delivered to the
petrochemical enterprises. From 1990 to 2007 the world liquefied gases consumption
has grown by 50 %. The world LHG consumption is expected to reach 300 million
tons by 2020. LHG production in Russia will be 12 million tons.
LHG is manufactured at gas processing plants, oil refineries and petrochemical complexes. Processing of the initial raw
materials is carried out by the petrochemical
companies, oil refineries and gas
processing plants. The production ratio is distributed as follows: The main LHG
manufacturers in Russia are gas processing plants, their share is about 46 %,
the share of petrochemical manufactures makes 39 %, oil refineries - 15 %. Processing of the secondary
raw materials and manufacture of liquefied hydrocarbon gas from it is carried
out by petrochemical
complexes which have Central Gas Fractionation Plants (CGFP) and gas
processing plants which have Gas Fractionation Plants (GFP).
Almost all the domestic manufacturers claim their readiness to increase
LHG production..
LHG transportation in Russia is carried out by three types of transport:
- Railway (rail tank cars and tank containers) - the main type of transport;
- Pipeline (interfactory product pipelines);
- Automobile (liquefied natural gas carriers and tank containers). LHG transportation in tank containers has becoming more and more popular recently. It is due to the time lag reduction with preservation of the quality guaranteed by the manufacturer.
