A process for removing diamondoids from a stream of natural gas. In this process, contact between a solvent liquid and natural gas containing diamondoids occurs in a stepwise counter current cascaded fashion. The stepwise counter-current cascaded arrangement substantially improves the removal of the light diamondoids (adamantane). The contacting (mixing) of the gas and solvent liquid allows the liquid to absorb the diamondoids contained in the gas. The gas and liquid are then separated thereby removing the diamondoids from the gas. In the preferred embodiment, a multi -staged trayed solvent contractor tower is used to facilitate the stepwise counter current cascaded contacting in the gas production process immediately after the separation of the gas from any liquid in the gas. The partially saturated diamondoid liquid solvent from the tower can also be mixed with the gas at a point before the separation of the gas from any reservoir formation liquid in order to enhance the diamondoid removal process.
