Abstract: Disclosed is a method that reforms flare gas or other raw natural gas source, using air without steam, to directly produce dimethyl ether (DME), a direct diesel substitute. The method first reforms an air-natural gas mixture at ambient atmospheric pressures, and then compresses the resulting CO-hydrogen-nitrogen gas mixture to 100-2,000 psi, and feeds it through a combined reactor which reacts the gas mixture directly into DME. The nitrogen is returned to the atmosphere. DME is an excellent diesel fuel, and can be used to displace significantly costlier and dirtier petroleum-based diesel fuel, while solving a critical problem with flaring or other wasted natural gas. For example, the roughly 120 billion cubic feet per year that was flared in North Dakota in 2014 could be converted into over 3 million tons of DME using the disclosed method.

Abstract: A plant for treating fluid products obtained from an oil well, to produce a hydrocarbon product, comprises a series of separators at progressively lower pressures, to which the fluid products are supplied in succession. A high pressure gas phase is obtained from the separator and is supplied to a flow restrictor so as to undergo cooling through the Joule Thomson effect, and then passed to a NGL separator to produce a natural gas liquid stream and a gaseous natural gas stream.

The synthetic crude oil is supplied to one of the separators, and the natural gas liquid stream is supplied to another of the separators; the pressure in the one separator is greater than the pressure in the other separator.
