A method and system are provided for preventing growth of liquid slugs in a stream of multiphase fluid flowing from a flowline into a gas/liquid separator (9) which has a liquid outlet (13) provided with liquid flow rate control means (15) and a gas outlet (14) provided with gas flow rate control means (16). The method comprises measuring a liquid level in the separator (9), as well as at least one control variable which is selected from the group of the liquid flow rate in the liquid outlet, the gas flow rate in the gas outlet, the sum of the liquid flow rate in the liquid outlet and the gas flow rate in the gas outlet, and the fluid pressure at or near the separator. The liquid flow rate control means (15) and the gas flow rate control means (16) are operated so as to reduce a difference between the measured liquid level and a selected reference value of the liquid level, and so as to reduce a difference between the measured control variable and a selected reference value of the control variable.
