The object of the present invention is a device which, being placed downstream of the pressure regulator in a facility for the supply of liquefied petroleum gases or natural gas, improves fuel consumption efficiency in the facility, through loss recovery and impurities removal, by means of a filtering process, and stabilization of the gas flow by rearranging the molecules thereof.
It is well known in the state of the art the use of liquefied petroleum gases that are present in natural gas, which is used as fuel in domestic, commercial and industrial environments.
Liquefied petroleum gases are a mixture of butane and propane, the main component of natural gas being methane which represents between 70% and 90% of the composition thereof. Both can be supplied for consumption in tanks either fixed or portable; in the case of fixed tanks the filling thereof is carried out by means of tankers, and in the case of portable tanks the filling thereof is carried out in industrial plants and its supply to the final user is carried out by replacing the empty tank for a full one.
The facility is similar both for natural gas and for liquefied petroleum gases, and it comprises a storage tank, a pressure regulator which reduces the fuel pressure inside the tank and controls the outgoing flow, the conveying pipeline which conveys the gas up to the devices consuming said fuel and among which there can be mentioned heating or household hot water boilers, cookers having gas burners or even fridges which use gas as an energy source.
The efficiency of these facilities depends on the flow rate and the supply pressure and on the impurities percentage the natural gas or liquefied petroleum gases contain. The supply pressure and flow rate are reduced by the pressure drop produced by the facility pipes and connections, such as shut-off cocks.
On the other hand, the supplied gas has certain impurities, such as other hydrocarbons, sulphur, water and other type of substances which, in its combustion process, produce highly polluting emissions or reduce the efficiency thereof.
The invention disclosed solves the aforementioned drawbacks by means of a device which features easy mounting and maintenance, cheap manufacturing costs, which improves combustion efficiency and which reduces polluting emissions.
The gas saving device for liquefied petroleum gases or natural gas object of the present invention, is of the type which are mounted downstream of the pressure regulator and upstream of the devices consuming the liquefied petroleum gases or the natural gas, such as, among others, boilers, cookers, fridges, etc . . .
The gas saving device comprises the following elements:
By means of the gas filtering, using activated carbon, practically all particle and impurities are removed, thus improving the effect of the steam chamber as far as filtering is concerned. Furthermore, by using the copper centrifugation coil the rearrangement of gas molecules is achieved, improving the stability of the flow rate throughout the whole facility and reducing the friction loss.

The gas saving device shown in
It is well known by those skilled in the art that the connections among the different elements of the invention and the supply facility are hermetically connected by means of the corresponding fittings and connections, such as gaskets, sealing elements, to guarantee the tightness of the facility and therefore to avoid gas leaks which can cause dangerous explosions.
The gas saving device disclosed in the present invention, increases the gas pressure and supply flow rate so as to fulfil the requirements of the devices consuming said gas, eliminates the impurities it contains and prevents the problem of freezing by insufficient gas vaporization, thereby causing the combustion to produce a less amount of polluting emissions and particles, and making said combustion be more efficient.
Another one of the multiple advantages of the invention is that the mounting thereof does not require modifications in the general facility already installed, but only the connection thereof to the inlet pipe for the gas supply.
