Zusammenfassung:The invention relates to a plant for natural gas odorization. According to the invention, the plant comprises an electronic flow-meter (13) mounted on the main gas pipeline (8), an odorization device (11), a tank of odorizing fluid (9) connected to a working vessel (3) with constant level, a dosing vessel (5), pipes (2, 4, 10) for equalization of pressure between said components, electrically operated valves (1, 19, 20, 21) controlled by a programmable automaton (12), the odorization process being programmed, in the normal operating mode, by dosing the odorizing fluid volume in proportion with the gas volume flowing through the main pipeline per time unit, and in the degraded mode, by continuous free-fall flowing of the odorizing fluid within the gas pipe, at a preset proportional flow rate, through the odorization device. Invenţia se referă la o instalaţie pentru odorizarea gazelor naturale. Instalaţia, conform invenţiei, cuprinde un debitmetru electronic (13) montat pe conducta principală de gaze (8), un dispozitiv de odorizare (11), un rezervor de fluid odorizant (9) conectat la un vas de lucru (3) cu nivel constant, un vas de dozare (5), conducte (2, 4, 10) pentru egalizarea presiunii între aceste componente, electroventile (1, 19, 20, 21) controlate de un automat programabil (12), procesul de odorizare fiind efectuat în mod programat, în regimul normal de funcţionare, printr-o dozare proporţională a volumului fluidului odorizant şi volumului de gaz scurs în unitatea de timp prin conducta principală, iar în regimul de avarie, prin scurgerea continuă, în cădere liberă şi cu un debit proporţional predozat al fluidului odorizant în conducta de gaze prin dispozitivul de odorizare.
