The object of the invention is a mobile venting system for carrying out the process of venting a storage tank (2) of the petroleum industry and transferring to installation (3) for recovering hydrocarbon/gas vapours removed from the tank (2) by sucking hydrocarbon/gas vapours from the storage tank (2) or by pumping air into the storage tank (2), which comprises a flow channel (4) for conveying hydrocarbon/gas vapours from the inlet (5) to the outlet (6) of the mobile venting system (1), a fan (7) with adjustable capacity for conveying hydrocarbon/gas vapours through the flow channel (4), wherein the part of the flow channel (4) from the inlet (5) of the mobile venting system (1) to the fan (7) being the suction part (4A) and the part of the flow channel (4) from the fan (7) to the outlet (6) of the mobile venting system (1) is the discharge part (4B) of the flow channel (4), an inlet manual valve (8) in the suction part (4A) for shutting off the mobile venting system (1) from external objects, an outlet manual valve (9) in the discharge part (4B) for shutting off the mobile venting system (1) from external objects, a first pressure sensor (14) in the suction part (4A) to control the low pressure in the system, a second pressure sensor (15) in the discharge part (4B) to control the high pressure in the system, a first flow meter (17) to control the flow of hydrocarbon vapours/gases through the flow channel (4), a first low explosion limit analyser (18) to analyse the gas concentration in the mobile venting system (1), a second low explosion limit analyser (19) to analyse the hydrocarbon/gas vapour concentration in the vented tank (2), a first automatic valve (10) in the suction part (4A) to automatically shut off the mobile venting system (1) from external objects, a second automatic valve (11) in the discharge section (4B) for automatically shutting off the mobile venting system (1) from external objects, a non-return valve (16) to prevent backflow of hydrocarbon/gas vapours in the flow channel (4), a controller (23) for receiving process signals and running the process.Furthermore, the subject of the invention is a system and method of venting using a venting system.
