SYSTEM FOR SEPARATING OUT VOLATILE DEGRADATION PRODUCTS, AND METHOD FOR OPERATING THE SYSTEM

摘要

A system for separating volatile degradation products out of a flue gas stream from a load-dependent combustion apparatus includes a CO2 separation apparatus, wherein the CO2 separation apparatus has fluidic coupling to the combustion apparatus, wherein the CO2 separation apparatus comprises at least one quench apparatus through which at least part of the flue gas stream flows and which at least partly forms an acidified quench condensate, and an absorber through which at least part of the flue gas stream flows, wherein at least part of the flue gas flows into a cleaning apparatus connected downstream of the absorber, wherein the cleaning apparatus is supplied with a cleaning medium for cleaning the flue gas, wherein the cleaning medium at least partly comprises the acidified quench condensate. A method for operating such a system includes separating volatile degradation products out of a flue gas stream.

1. A plant for capturing volatile degradation products from a flue gas stream of a load-dependent combustion apparatus comprising
a CO2 capture apparatus, wherein the CO2 capture apparatus is fluidly coupled to the combustion apparatus, wherein the CO2 capture apparatus comprises at least one quenching apparatus which is at least partly traversed by the flue gas stream to at least partly form an acidified quench condensate and an absorber which is at least partly traversed by the flue gas stream, and a cleaning apparatus arranged downstream of the absorber and in fluid communication therewith, into which the flue gas at least partly flows, wherein the cleaning apparatus is supplied with a cleaning medium for cleaning the flue gas, wherein the cleaning medium at least partly comprises the acidified quench condensate.
