Claim:
1. A mobile system for converting raw natural gas into dimethyl ether (DME) using air as a source of oxygen, comprising: a syngas generator for generating syngas from the raw natural gas and the air; a syngas compressor for compressing the syngas; a DME synthesis unit for synthesizing the DME from the compressed syngas, comprising a single reaction chamber comprising a mixed catalyst bed of hydrogenation and dehydration catalysts; and a DME purification unit for separating the DME from side products from the DME synthesis unit to produce a purified DME stream, wherein the DME purification unit comprises an absorption column and a stripper column, wherein the absorption column comprises an aqueous solvent for absorbing the DME while effluent gases (N
