Substantiation of solutions for enhancing the environmental safety level of a marine oil terminal under conditions of high intensification of technological processes

Currently, there is a significant intensification of technological processes during the operation of pipeline systems at marine oil terminals. In the context of a manifold increase in cargo flows, there is a rise in corresponding complications that require urgent solutions. It is important to note that the resolution of these problematic aspects must have a proper scientific basis, rather than blindly following the contemporary environmental agenda. In this regard, the issues of substantiating technical and technological solutions to ensure resource-efficient, environmentally friendly, and safe operation of pipeline systems at marine oil terminals are highly relevant. This study examines technological solutions aimed at reducing atmospheric emissions during tanker loading. Of particular importance during these operations is the initial stage of loading, when the pressure of the gas phase inside the tanker increases rapidly. The work demonstrates that at this stage, by processing data on the gas phase pressure value received from the tanker, it is possible to predict in advance how intensively the loaded cargo is evaporating. Thus, negative consequences such as the opening of the mast riser and the release of excess gas-air mixture into the atmosphere can be prevented by, for example, increasing the rotation speed of the gas blower on the berth. However, solving the inverse problem of identifying the process parameters is very difficult due to its ill-posed nature. In this regard, an algorithm is proposed, based on an equation derived in earlier works, involving series expansion and identification of the mass transfer parameter from the surface of the evaporating cargo. The proposed method will make it possible to implement in practice a warning system within the loading control system about a dangerous rate of pressure increase and to take preventive actions.
