Abstract: A method for handling a vent gas mixture originating from a fuel system and comprising fuel vapours and inert gas. The method involves: directing the vent gas mixture from the fuel system to a condenser, the condenser condensing at least a majority of the fuel vapours into liquid fuel such that the vent gas mixture comprises liquid fuel and inert gas, separating the liquid fuel and the inert gas of the vent gas mixture from the condenser in a vapour-liquid separator, and selectively directing the liquid fuel from the separator to a boiler system, when the boiler system is in a hot condition and is ready to receive and combust the liquid fuel of the vent gas mixture, or storing the liquid fuel in the separator and/or in a separate storage tank until the boiler system is in the hot condition and is ready to receive/combust the liquid fuel.

Abstract: An arrangement and a method for handling purged alcohol-based fuel originating from an alcohol fuel system configured to fuel an alcohol fueled engine, the arrangement comprising: a boiler system comprising a burner and a fuel inlet configured to selectively supply a fuel and thereby selectively sustain a primary flame in the burner for production of heat and/or steam in the boiler system, a purge connection configured to receive a purge mixture purged from the alcohol fuel system using an inert gas, the purge mixture comprising a mixture of the inert gas and purged alcohol-based fuel, and a vapor-liquid separator.
