Abstract
A process for generating a main fuel composition comprising methanol and water and not more than 20% by weight dimethyl ether, and a fumigant comprising dimethyl ether, the process comprising: providing a pre-fuel composition comprising methanol and dimethyl ether, adding water to the pre-fuel composition to cause or aid evaporation of at least a portion of the dimethyl ether from the pre-fuel composition, collecting the portion of dimethyl ether evaporated from the pre-fuel composition for use as a fumigant, and using the remainder of the pre-fuel composition comprising methanol and water as a main fuel composition. The water may be at a temperature above ambient.

A process for generating a main fuel composition comprising methanol and water and not more than 20% by weight dimethyl ether, and a fumigant comprising dimethyl ether, the process comprising:
- providing a pre-fuel composition comprising methanol and dimethyl ether,
- adding water to the pre-fuel composition to cause or aid evaporation of at least a portion of the dimethyl ether from the pre-fuel composition,
- collecting the portion of dimethyl ether evaporated from the pre-fuel composition for use as a fumigant, and
- using the remainder of the pre-fuel composition comprising methanol and water as a main fuel composition.
A process of operating a compression ignition engine using a main fuel comprising methanol and water and not more than 20% by weight dimethyl ether, including:
- providing a pre-fuel composition comprising methanol and dimethyl ether,
- adding water to the pre-fuel composition to cause or aid evaporation of at least a portion of the dimethyl ether from the pre-fuel composition,
- collecting the portion of dimethyl ether evaporated from the pre-fuel composition for use as a fumigant,
- using the remainder of the pre-fuel composition comprising methanol and water as a main fuel composition,
- fumigating an intake air stream of the compression ignition engine with the fumigant comprising dimethyl ether;
- introducing the fumigated intake air into a combustion chamber in the engine and compressing the intake air;
- introducing the main fuel into the combustion chamber;
- and
- igniting the main fuel/air mixture to drive the engine.
A process for generating power using a compression ignition engine fuelled by a main fuel composition comprising methanol and water and not more than 20% dimethyl ether, the process comprising:
- providing a pre-fuel composition comprising methanol and dimethyl ether,
- adding water to the pre-fuel composition to cause or aid evaporation of at least a portion of the dimethyl ether from the pre-fuel composition,
- collecting the portion of dimethyl ether evaporated from the pre-fuel composition for use as a fumigant,
- using the remainder of the pre-fuel composition comprising methanol and water as a main fuel composition,
- operating a compression ignition engine using the main fuel composition to generate power;
- fumigating the inlet air stream of the compression ignition engine with the fumigant comprising dimethyl ether;
- treating engine exhaust to recover exhaust heat and/or water from the engine, and
- redirecting the heat and/or water for further use.
A method for supplying fuel to a compression ignition engine, the method comprising:
- supplying a pre-fuel composition comprising methanol and dimethyl ether,
- adding water to the pre-fuel composition to cause or aid evaporation of at least a portion of the dimethyl ether from the pre-fuel composition,
- supplying the portion of dimethyl ether evaporated from the pre-fuel composition to an air intake of the compression ignition engine, or to a tank that is in fluid connection to the air intake of the compression ignition engine, for use as a fumigant,
- supplying the remainder of the pre-fuel composition comprising methanol and water to a second tank that is in fluid connection to a combustion chamber of the compression ignition engine for use as a main fuel composition.
