The present invention relates to a separation process of natural gas from gaseous compounds present at the wellhead by means of at least two adsorption columns, each containing an adsorbing solid and one operating at a higher pressure than the other, said process being characterized in that: -the compression ratio is within the range of 1.1 to 10; -the ratio between the characteristic convective time through the column and the characteristic diffusive time in the adsorbing solid is higher than 1.
