Title:
固体フィードの熱分解によって生じた生ガスの処理方法および処理プラント
Document Type and Number:
Japanese Patent JP4505178
Kind Code:
B2
Abstract:
A mechanical dust extraction process and a chemical treatment of the gases are carried out simultaneously at the furnace outlet. The decomposition of a solid load under heat generates raw gases containing solid and gaseous pollutants at the furnace outlet. Reactants, additives or catalysts are used for the chemical treatment of the gases. The raw gases are centrifuged to remove the dust. Reactants/additives are used to carry out a gas/solid or gas/gas reaction allowing the chemical treatment of the gas. Base components are used to carry out the gas/solid reaction and oxygenated components for the gas/gas reaction. The catalyst is used for conversion of the gas. An Independent claim is also included for an apparatus for the above process, containing a furnace (10) connected to a recovery chamber (22) for solid residues and raw gases via an open face (20). The chamber contains a treatment device (24) integrating mechanical dust extraction and means of chemically treating the gas. The treatment device has a cylindrical envelope (30) with an inlet (34) for the raw gases, at least one inlet (36) for chemical components and an outlet (40) for the gases after treatment. The inlets are tangential relative to the envelope and the treatment device is connected to a recycling device (56) for the chemical components.
