Abstract
A method and device for removing solid residues from a gas purification installation are presented. After discharge of a batch of solid residues into a first closed vessel, the vessel is isolated with respect to the gas purification installation. At least one pressurized purge gas is then passed through this batch of solid residues, so as to create a static or fluidized bed of the solid residues. The purge gases are then removed in a controlled manner from the first closed vessel. The solid residues are removed into a transport pipe and are transported through the pipe in suspension in a pressurized gas.
Claims22
A method for removing granular or pulverulent solid residues from a gas purification installation, comprising the steps of:
- discharging a batch of solid residues from said gas purification installation through a discharge pipe into at least one first closed vessel;
- isolating said at least One first closed vessel with respect to the gas purification installation by leak tight closure of said discharge pipe subsequent to said discharging step;
- passing at least one pressurized purge gas through said solid residues contained in said first closed vessel so as to create and sustain a static or fluidized bed of said solid residues in said at least one first closed vessel;
- controllably removing a flow rate of purge gas from said first closed vessel;
- progressively (removing) discharging said solid residues from said at least one first closed vessel into a transport pipe;
- and
- transporting said solid residues through said transport pipe in suspension in a pressurized gas.
The method of claim I wherein said at least one pressurized purge gas comprises a heated gas having a very low relative humidity.
