Zusammenfassung:	In accordance with one aspect of the present disclosure, a mobile machine (102) includes a LNG fuel tank (106) to provide natural gas to a natural gas engine (104), a pressure relief valve (202) to relieve pressure to a relief vent line (204, and a liquid separation device (108). The liquid separation device (108) includes a canister (302) defining an interior space (304) and having a top end (306) and a bottom end (308), a LNG inlet (310) configured to receive mixed phase fluid into the canister from the relief vent line, a separator (312) disposed within the interior space and fluidly connected to the LNG inlet, the separator configured to direct condensed liquid to the bottom end and to pass vapor to the interior space, a vapor outlet (320) disposed on the top end of the canister, and a liquid drain (322) disposed on the bottom end of the canister.
