<p>The invention relates to a method and an apparatus for removal of acid gas from natural gas by means of a chemical absorbent. The method comprises the steps of - supplying pressurized natural gas containing acid gas to an outer perimeter (111; 411) of at least one annular absorber packing (102a, 102b; 400), wherein the natural gas is forced towards the inner perimeter (112; 412) of the annular absorber packing (102a, 102b; 400); - supplying a chemical absorbent to an inner perimeter (112; 412) of an annular absorber packing (102a, 102b; 400); - rotating the annular absorber packing about its longitudinal axis, subjecting the chemical absorbent to a centrifugal force sufficient to force the absorbent towards the outer perimeter (111; 411) of the annular absorber packing (102a, 102b; 400) in the opposite direction of the natural gas; wherein a cross flow for mass transfer of acid gas (CO2/H2S) from the natural gas to the absorbent occurs to produce sweet natural gas.</p> |
