A method and system for purification of a pressurized gas stream, wherein the method includes in a first absorption step bringing the pressurized gas stream in direct contact with a first absorption solution absorbing at least part of the acidic gases, in the gas stream obtaining a gas liquid mixture; and separating the gas liquid mixture in a partly purified pressurized gas stream and a first rich absorption solution. In a second downstream absorption step bringing the partly purified pressurized gas in contact with a second absorption solution through a membrane contactor, obtaining a second rich absorption solution and a purified pressurized gas stream. The first absorption solution is a partially lean absorption solution.
