Abstract
A method is provided for separating offgas from solid and/or liquid reaction products in the combustion of a metal M selected from alkali metals, alkaline earth metals, Al and Zn, and mixtures thereof, with a combustion gas. In a reaction step, the combustion gas is combusted with the metal M, forming offgas and further solid and/or liquid reaction products, and, in a separation step, the offgas is separated from the solid and/or liquid reaction products. In the separation step, a carrier gas is additionally added and the carrier gas is removed as a mixture with the offgas.
Claims14
A process for separating offgas from solid and/or liquid reaction products in the combustion of a metal M selected from among alkali metals, alkaline earth metals, Al and Zn and mixtures thereof by a combustion gas, the method comprising:
- burning the combustion gas with the metal M in a reaction step to form offgas and further solid and/or liquid reaction products;
- and
- separating the offgas from the solid and/or liquid reaction products, and
- additionally adding a carrier gas in the separation step and discharging the carrier gas as a mixture with the offgas.
An apparatus for the separation of offgas in the combustion of a metal M selected from among alkali metals, alkaline earth metals, Al and Zn and mixtures thereof by a combustion gas, the apparatus comprising:
- a burner configured to burn the metal M by means of the combustion gas;
- a first feed device configured to feed combustion gas to the burner;
- a second feed device configured to feed metal M to the burner;
- a reactor connected to the burner;
- a third feed device configured to feed carrier gas to the reactor;
- a first discharge device configured to discharge a mixture of the offgas of the combustion of metal M via the combustion gas and the carrier gas;
- and
- a second discharge device configured to discharge solid and/or liquid reaction products of the combustion of metal M via the combustion gas.
