Fossil fuel-fired power station having a removal apparatus for carbon dioxide and process for separating carbon dioxide from an offgas from a fossil fuel-fired power station

摘要

A fossil fuel-fired power station having a removal apparatus for carbon dioxide which is located downstream of a combustion facility and through which an offgas containing carbon dioxide may flow is provided. The removal apparatus comprises an absorption unit and a desorption unit. The desorption unit is connected to a renewable energy source.

主权项

1. A fossil-fired power plant, comprising:
a separation device for carbon dioxide which follows a combustion device and through which a carbon dioxide-containing exhaust gas is capable of flowing, the separation device, comprising:
an absorption unit, anda desorption unit; a renewable energy source; and a heat accumulator, wherein the desorption unit is connected to the renewable energy source, wherein the heat accumulator is connected between the desorption unit and the renewable energy source, wherein a plurality of absorbent accumulators are connected into a scrubbing agent circuit of the separation device for carbon dioxide, and wherein the desorption unit is connected to a heat exchanger that introduces heat energy from steam generated from the fossil-fired power plant into the desorption unit so as to compensate for an event of an insufficient supply of heat energy by the renewable energy source to the desorption unit.
