Abrégé

In one embodiment of a method for vaporizing liquids such as fuels, the liquid is sprayed into a chamber such that the spray does not impinge on any surface. The energy for vaporization is supplied through the injection of a hot diluent such as nitrogen or oxygen depleted air. Additional heat is added through the surface. In another embodiment, the liquid is sprayed onto a hot surface using a geometry such that the entire spray is intercepted by the surface. Heat is added through the surface to maintain an internal surface temperature above the boiling point of the least volatile component of the liquid. The liquid droplets impinging on the surface are thus flash vaporized. A carrier gas may also be flowed through the vaporizer to control the dew point of the resultant vapor phase mixture.

A process is provided, which comprises transforming a synthesis gas into a liquid fuel, producing a fuel gas using the liquid fuel and a first gas, the first gas having an oxygen content less than that of ambient air, and contacting the fuel gas with a second gas, the second gas comprising at least one oxidizing agent, to form a combustion gas. Systems for carrying out the process are also provided.

Abrégé

The described fuel conditioning unit includes a vaporization chamber, a heating element attached to a sidewall of the vaporization chamber, and at least one fuel nozzle, mounted on an end wall of the vaporization chamber, in fluid communication with a liquid fuel supply to produce a spray with a spray angle such that all of the spray impinges on an interior surface of the sidewall. At least one diluent gas port is in fluid communication with the vaporization chamber and a supply of diluent gas. The heating element is configured to heat a portion of the sidewall upon which the spray impinges to a temperature sufficient to flash vaporize the liquid fuel spray as it contacts the sidewall, and the diluent gas and vaporized liquid fuel combine to form a mixture that has a lower dew point than that of the liquid fuel in the absence of the diluent gas.
