A small apparatus for the production of mixtures of LPG vapor and air, also called synthetic natural gas, with properties that allow these mixtures to be used in place of natural gas in mostly temporary installations for residential and industrial or commercial installations. The entire apparatus is designed to produce synthetic natural gas without permanent presence of operating personnel. Noise, typically associated with the operation of venturi-type vapor/air mixing devices, is suppressed by a combination of an air-intake filter and a noise-reducing device to a level that make the apparatus suitable for installations close to residential developments. A second vapor/air mixing apparatus, identical to the main system, is installed on the same support frame, acting as a backup device for the main system in situations of equipment malfunctions or temporary system overload. Equipment malfunctions are reported to centralized monitoring stations by means of a telephone-based signaling device. Backup operating energy is provided by means of a solar-powered current converter with battery backup.
