The invention discloses a station yard desulfurization device of low-latent-sulfur natural gas, and belongs to the field of petroleum engineering. The station yard desulfurization device of the low-latent-sulfur natural gas comprises a gas-liquid separation device, a heating device and a liquid desulfurization device. Gas enters the gas inlet end of the gas-liquid separation device through a pipeline. The gas outlet end of the gas-liquid separation device passes through the heating device to be connected with the gas inlet end of the liquid desulfurization device through a pipeline. The gas outlet end of the liquid desulfurization device conveys gas through a pipeline. By means of the liquid desulfurization device, it can be effectively avoided that two desulfurization towers need to be used for alternate operation during desulfurization through a solid dry method, and workloads of field operators can be relieved; generated desulfurization products are all water-soluble liquid, so thesafety and reliability of the station yard desulfurization device are higher, waste desulfurization agents are free of toxin and harm and can be injected back into a stratum together with processed natural gas, the processing difficulty is low, and the environment can hardly be polluted.
