Abstract: A fabric filter (1) has at least a first compartment (2) and a second compartment (4). A hopper (42) is adapted for fluidisation of dust collected in the compartments (2, 4) to form a bed (52) of fluidised dust.

Abstract: A hydrogen purification method that is used to separate hydrogen gas from a source gas. A hydrogen separator into which flows the source. Within the hydrogen separator is at least one hydrogen permeable tube that is made of a hydrogen permeable material. A support tube is provided for each hydrogen permeable tube. A support tube is coaxially aligned with the hydrogen permeable tube, wherein a micro-channel exists between the hydrogen permeable tube and the support tube in an area of overlap. The source gas is introduced into the micro-channel. The source gas spreads thinly over the hydrogen permeable tube in the micro-channel. The restrictions of the micro-channel cause the source gas to embody turbulent flow characteristics as it flows through the micro-channel. The turbulent flow causes the hydrogen separator to separate hydrogen from the source gas in a highly efficient manner.
