Simple and Effective – the Conditioned Dry Sorption Process for Flue Gas Treatment Downstream Waste Incinerators

The conditioned dry sorption with utilisation of Ca-based additive powder qualities became increasingly important in Europe in the course of the past years regarding the application waste incineration plants. Starting from the prohibition of disposal in the year 2005 until today, the vast majority of new plants for waste and RDF combustion in Germany has been provided with a conditioned dry sorption system. This trend continues with regard to the new planning of WtE-plants in Europe and other parts of the world.

As a result of continuous further developments, this procedure gave proof of its reliability, performance and not least of its economic efficiency in comparison to other technologies available on the market. Particularly in the course of the last years, technical optimisation steps had been necessary to be able to keep up with the increasing requirements, resulting from higher crude gas loads and the demand for lower emission values. A further aspect as urge for the optimisation of process technologies is the constant pressure to increase the competitiveness of plants by means of low operating costs.

In the following the conditioned dry sorption process is introduced including possible steps for optimisation and an assessment on the basis of practical examples. It may be remarked in addition that the main focus of this lecture is on the sorption of the acid crude gas components HCl and SOx. The qualification of process for the simultaneous separation of further pollutants existing in the gas such as e.g. dioxins/furans as well as mercury and other heavy metal compounds or also the excellent separation of filter dust of type PM 10 and PM 2.5 will not be discussed in this lecture.

Significance of and Challenges for Flue Gas Treatment Systems in Waste Incineration
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
Flue gas cleaning downstream of waste incineration plants had its origins in the increased construction and deployment of such plants to counter rising air pollution in the nineteen-sixties. Back then, the ever-growing burden on the environment caused lawmakers to start enacting emission limits for air pollution control. An unceasing series of environmental scandals and increasingly better analytical methods and measuring instrumentation led to a constant reduction of the emission limits and, consequently, to ongoing adjustment and further development of the necessary process stages in flue gas cleaning. As a result, today minimum emissions can be reached even under the challenging condition of deployment of a very inhomogeneous fuel (waste) and, hence, waste incineration today is no longer a key contributor to air pollution. Today, the need for flue gas cleaning is not called into doubt anymore and has long become a matter of course in the industry and in society at large. Apart from ensuring efficient elimination of noxious gases, the focus of today’s further developments is on issues such as energy efficiency, minimization of input materials and recovery and recycling of by-products from flue gas cleaning as valuable raw materials. These issues are also deemed to be key challenges, especially when it comes to selecting sites for new plants in such a manner that potential synergies can be exploited. Such aspects will also have to be considered in the plans for the predicted mega-cities of the future.

Flue Gas Treatment – State of the Art

For the removal of air pollutants from the flue gas, a flue gas treatment system is required downstream the boiler. Such treatment systems consist of a system of cleaning processes for the reduction of particulate, vapour and gaseous substances in the flue gas.

SNCR for Low NOx Emissions – Case Study of a Swedish Waste-to-Energy Plant –

All over the world people understand that reducing air pollution is essential to increase health and comfort of people. Nitrogen oxides (NOx) are among the main components of pollutants caused by combustion processes. It is toxic by direct contact and it causes acid rain.

Einhaltung verschärfter NOx- und NH3-Grenzwerte bei bestehenden Anlagen – Vorgehen und Lösungsansätze anhand von Praxisbeispielen –
© TK Verlag - Fachverlag für Kreislaufwirtschaft (1/2015)
Aufgrund der künftigen neuen bzw. verschärften Grenzwerte für Ammoniak und NOx besteht die Notwendigkeit zum Handeln für Betreiber von thermischen Abfallanlagen. Auch wirtschaftliche Gründe können zur Installation oder zur Ertüchtigung einer SNCR-Anlage mit erhöhter Performance führen. Ein großes Spektrum von Anpassungen steht dabei zur Verfügung, für das ERC Technik systematische Unterstützung bei der Konzept- und Entscheidungsfindung bis hin zur Umsetzung der Maßnahmen bietet.

SNCR-Lösungen für steigende Anforderungen in unterschiedlichen Feuerungsanlagen
© TK Verlag - Fachverlag für Kreislaufwirtschaft (1/2015)
Die ersten SNCR-Anlagen wurden ab etwa 1990 zumeist für Abfallverbrennungsanlagen eingesetzt, in denen nur eine moderate NOx-Abscheidung von vierzig bis fünfzig Prozent gefordert wurde, was auch bei den in diesen Feuerungen üblichen Temperaturschieflagen kein unlösbares Problem darstellte. Für höhere Abscheidegrade wurde das SNCR-Verfahren damals als nicht geeignet beurteilt, sodass hierfür in der Regel SCR-Verfahren vorgesehen wurden.
