Mixture of LPG and Air Interchangeable to Natural Gas
In this case, CAM supplied all the components to produce an LPG-Air mixture interchangeable to natural gas, starting from liquid LPG upload to the mixture delivered to the network; namely, storage, vaporizing, pumping, pressure regulators, and mixing units. Due to the considerable amount of gas to be processed and the large extension of the city, the plant has been divided into several functional units. A great storage area (nine 200 m³ tanks) with unloading compressors, pumps, hot water vaporizers and main pressure regulators, is located in a remote area and produces the LPG-Vapor that feeds the mixing stations. Three mixing stations, complete with superheaters, second-stage regulators, and mixers, are placed inside the urban area and produce the LPG / air mixture for the end users. All the units have boilers which provide the hot water either for vaporizers or for superheaters. A medium pressure LPG-Vapor line, coming from the storage area, also feeds the three mixing stations. The mixing stations are connected to each other by the low pressure mixture network.
