Claim 3:
4. A method for expanding a fluid by means of a device (1) comprising an inlet (2) for a high pressure fluid, an outlet (3) for a low pressure fluid, a control valve (4) between the inlet (2) and outlet (3) for expanding the fluid, and an expander (5) connected in parallel with the control valve (4), wherein the method comprises:
controlling a flow rate (Qklep) of the fluid passing through the control valve (4) such that a pressure at the outlet (3) is regulated at a predefined pressure level; and
controlling a flow rate of the fluid passing through the expander (5) on the basis of the flow rate (Qklep) passing through the control valve (4).
