Innovative Solutions for NOx and Hg Abatement in WTE Plants
Budget: ₹1,500 – ₹12,500 INR
ABSTRACT
Waste-to-energy (WTE) plants convert unsorted urban waste into energy through a process of incineration in a boiler. The combustion of waste generates a flue gas containing different concentrations of pollutants, such as acid gases, mercury, metals, and volatile organic compounds. A2A Ambiente is looking for two different types of innovative solutions that could capture and remove:
NOx from flue gas at low temperatures (T around 140°C);
Hg from flue gas at high temperatures for a dry system technology.
This Theoretical Challenge requires only a written proposal.
OVERVIEW
A2A Ambiente’s waste-to-energy plants transform undifferentiated urban waste into energy through an incineration process in a boiler and the combustion of waste generates pollutants that shall be removed from the flue gases. Today there is a significant reduction in emissions in the waste incineration sector, but at the same time available technologies must be adapted to the new standards. For these reasons, A2A Ambiente is looking for solutions for the innovative development of two main systems:
NOx abatement from flue gas at low temperatures, in order to reduce costs in fuel consumption.
Mercury removal at high temperatures, in order to reduce peaks at the stack due to waste heterogeneity in the bunker (where it is stored before being burned) and in the combustion chamber,
This is a Theoretical Challenge that requires only a written proposal to be submitted. The Challenge award will be contingent upon theoretical evaluation of the proposal by the Seeker.
