Abstract

Method and device for separation of a fluid comprising several fluid components, especially separation of a well fluid in connection with a pipe for production of hydrocarbons/water. The fluid is fed into one end of a mainly horizontal pipe of a length adapted to the current conditions of flow, with the fluid flowing through the pipe at such a speed that it is separated. During separation fluid components with a low density are formed in the top part of the pipe and fluid components with a higher density are formed in the lower part of the pipe. The fluid components are taken out through separate outlets.
