While being prepared for long-distance transport, gas is subjected to multiple cooling procedures that use air-cooling units. This is necessary for reducing the gas volume and preventing the gas from affecting the pipeline and the permafrozen soil where the pipeline is laid. ACU control systems are mainly tasked to sustain the necessary gas temperature at the unit outlet, which must provide sufficient cooling while also preventing the generation of hydrates in the ACU tubes. The ACU outlet temperature is the mean temperature, as temperatures of individual outlets might very greatly. Therefore, normal ACU operation requires a mathematical thermal field model that could be used to find the temperature at any point of the pipe. The paper proposes a thermal field simulation model that can be used to find temperatures at specific points of heat-transfer pipes as a function of the ambient temperature for any fan-vs-fan performance ratio. Experimental verification of the model showed good repeatability.
