Abstract
In a process for separating fly-ash from crude synthesis gas a high-pressure cyclone is used, having a central pipe ranging from above its gas outlet to below its solids outlet. Through this pipe gas is removed which emanates from a sluice system to which the cyclone is connected by means of its solids outlet. In this way the efficiency of the cyclone is improved.
