Abstract

A method for the separate discharge of the individual phase streams of a multiple component flow comprising a high viscosity slow flowing liquid or suspension and a gas flowing at at least 100 times faster with the volumetric ratio of the gas to the liquid being greater than 1:1. The multicomponent flow is transversely fed through an inlet and directly into a rotating helical channel for conveying liquid in one direction. The channel has a liquid outlet spaced from the inlet in the one direction and a gas outlet spaced from the inlet in the opposite direction. A gas shut-off is formed between the inlet and the liquid outlet so as to effect the discharge of gas through the gas outlet in the opposite direction during the conveying of the liquid by the helical channel to the liquid outlet in the one direction.
