The Vane Inlet Diffuser -Schoepentoeter device is commonly used for introducing gas/liquid mixtures into a vessel or column. The purpose of a vane inlet diffuser is to obtain a separation of liquid from the vapours and to provide proper vapour distribution in the gas compartment of the vessel. This is obtained by slicing up the feed vapour/liquid mixture into a series of flat jets. These jets dissipate a large part of the kinetic energy of the feed mixture and therefore a inlet device allows a considerable height reduction of the vessel and a reduction of the inlet nozzle size.
Due to its optimal design and large open areas, the Vane Inlet Diffuser smoothly introduces the fluid into the vessel. As the fluid is evenly distributed among the vanes, the velocity is significantly reduced. This results in an increased gas-liquid separation by gravity at the inlet nozzle, improving the overall separation efficiency of the vessel.
Adverse effects experienced with other inlet devices, like liquid entrainment due to high shear forces, do not occur in the Vane Inlet Diffuser. With the gas velocity reduced to a minimum, negative effects like swirling or liquid re-entrainment will be avoided. Due to the large open areas there is no pressure drop and no potential for blockage. Furthermore, no maintenance is required due to the very robust design.
The advantages of the Vane Inlet Diffuser are:
