A SYSTEM AND A METHOD FOR THE WITHDRAWAL OF PARTICULATE SOLID MATTER FROM A PRESSURIZED CONTAINER CONTAINING A GAS, AND USE THEREOF

WIPO Patent Application WO/2010/139331

A4

A method and a system for the withdrawal of solid matter particles from a pressurized container, and use thereof The method comprises withdrawal of solid matter particles from a container (1 ) pressurized by a gas, wherein the particles are transported out of the container (1), are conveyed through a zone with relatively densely packed particles (3a), and pass a metering mechanism (4, 41, 4"), across which there is a significantly reduced or no gas pressure difference, said gas being subjected to a pressure loss at the passage between the densely packed particles in the zone (3a) forwardly to the metering mechanism (4, 4', 4"). The system comprises a transport pipe (3), in which a zone (3a) of relatively densely packed particles is created, said gas being subjected to a pressure loss at its passage through this zone of particles because of the flow resistance in it. The transport pipe (3) is dimensioned so that there is a significantly reduced or no gas pressure difference across the subsequent metering mechanism (4, 4', 4"). A low steam loss is achieved by the use of the system and the method when particles are dried with superheated steam.
