This study deals with behaviour and washing efficiency of a venturi scrubber in self-priming operation. UsuaIly the washing
liquid is injected into the throat by means of a pump, in such a way that the amount of liquid added per cubic metre of gas is
adjustable independent from the gas flow rate. In contrast to this kind of design, the venturi scrubber used works via a
self-priming operation, i.e. the washing liquid is injected by means of a pressure difference between the inside and outside of the
venturi throat as a result of the hydrostatic pressure of the liquid and the static pressure of the flowing gas.
