A mobile system and method that reform flare gas, methane, or natural gas, using air without steam, to directly produce methanol, a clean burning gasoline blend, component, and/or substitute are disclosed. The system first reforms the air-methane mixture at ambient atmospheric pressure, then compresses the resulting CO-hydrogen-nitrogen gas mixture to 600 psi, and feeds it through a methanol reactor which reacts the gas mixture directly into methanol. The nitrogen is returned by the system back to the atmosphere. Methanol is a clean burning gasoline substitute, and can be used to displace significantly costlier and dirtier petroleum-based fuel, while solving a critical problem with flaring. For example, the over 120 billion cubic feet per year that was flared in North Dakota in 2014 could be converted into over 6 million tons of methanol. 1. A mobile system for converting raw natural gas into methanol , comprising:a syngas generator for generating syngas from the raw natural gas and air;a syngas compressor for compressing the syngas;a reactor for converting carbon monoxide and hydrogen in the syngas to methanol; anda power generator for using unreacted carbon monoxide and hydrogen to generate power, wherein some of the power is used to power the syngas compressor.2. The system of claim 1 , further comprising:a sulfur removal unit for removing sulfur from the raw natural gas stream.3. The system of claim 1 , wherein the syngas generator comprises an air reforming unit for reforming the raw natural gas and air in presence of a steam reforming catalyst.4. The system of claim 3 , wherein air enriched in oxygen is added to the air reforming unit to increase concentrations of hydrogen and carbon monoxide in the syngas.5. The system of claim 3 , wherein distilled water is added to the air reforming unit for preventing catalyst coking.6. The system of claim 5 , wherein the distilled water is recycled to the air reforming unit from a condenser downstream from an air ...
