Reducing the Mercury Emissions from a Sewage Sludge Incineration Plant
Chemical Engineering & Technology, 1998Co-Authors: Hanns-rudolf Paur, Hubert Büchele, Sune Andreasson, Rolf WillmsAbstract:The studies discussed in this paper were conducted to develop and test the MercOx process in which Hg 0 can be removed from the offgas of a sewage sludge Incineration Plant almost without giving rise to any waste. For this purpose, the Hg 0 carried in the offgas is converted by the H 2 O 2 oxidant into highly soluble ionic mercury, which is separated in a downstream scrubbing stage. The dissolved mercury can then be removed from the liquid effluent by ion exchangers and precipitating agents, respectively, and disposed of.

municipal solid waste Incineration Plant a multi step approach to the evaluation of an energy recovery configuration
Waste Management, 2017Co-Authors: Deborah Panepinto, Mariachiara ZanettiAbstract:Abstract This study proposes a multi-step approach to evaluating the environmental and economic aspects of a thermal treatment Plant with an energy-recovery configuration. In order to validate the proposed approach, the Turin Incineration Plant was analyzed, and the potential of the incinerator and several different possible connections to the district heating network were then considered. Both local and global environmental balances were defined. The global-scale results provided information on carbon dioxide emissions, while the local-scale results were used as reference values for the implementation of a Gaussian model that could evaluate the actual concentrations of pollutants released into the atmosphere. The economic aspects were then analyzed, and a correspondence between the environmental and economic advantages defined. The results showed a high energy efficiency for the combined production of heat and electricity, and the opportunity to minimize environmental impacts by including cogeneration in a district heating scheme. This scheme showed an environmental advantage, whereas the electricity-only configuration showed an economic advantage. A change in the thermal energy price (specifically, to 40 €/MWh), however, would make it possible to obtain both environmental and economic advantages.

environmental evaluation of the electric and cogenerative configurations for the energy recovery of the turin municipal solid waste Incineration Plant
Waste Management & Research, 2014Co-Authors: Deborah Panepinto, Giuseppe GenonAbstract:Given the desirability of reducing fossil fuel consumption, together with the increasing production of combustible solid wastes, there is clearly a need for waste treatment systems that achieve both volume reduction and energy recovery. Direct Incineration method is one such system. The aim of this work was to analyze the municipal solid waste Incineration Plant currently under construction in the province of Turin (Piedmont, North Italy), especially the potential for energy recovery, and the consequent environmental effects. We analyzed two kinds of energy recovery: electric energy (electrical configuration) only, and both electric and thermal energy (cogenerative configuration), in this case with a different connection hypothesis to the district heating network. After we had evaluated the potential of the incinerator and considered local demographic, energy and urban planning effects, we assumed different possible connections to the district heating network. We computed the local and global environmenta...

environmental and economic analysis of the turin Incineration Plant
Waste Management, 2014Co-Authors: Deborah Panepinto, Annamaria Senor, Giuseppe GenonAbstract:There has been a great deal of attention given to the necessity to improve innovative systems of energy recovery and this, together with a positive trend in the increase of waste, has lead to a need to consider systems of the disposal and treatment of waste that enable the reduction of both volumes and energy and, if possible, a recovery of materials. Incineration is a system that offers both of the aforementioned opportunities (volume reduction and energy recovery). The aim of this work is to analyze the waste Incineration Plant that is built in Turin (Piedmont, North Italy). We analyze two different kinds of energy recovery: from one side, a recovery only of electric energy (electrical configuration) and on the other side, a recovery both of electric and thermal energy (cogenerative configuration) with different hypotheses on their connections to the district heating network from an environmental and economic point of view. From an environmental point of view the aim is to understand which of the two energy recovery configurations is more convenient (in terms of environmental compatibility) and from an economic point of view the aim is to understand if the environmental convenience corresponds to the economic convenience.

inhibitory effect of high nh4 n concentration on anaerobic biotreatment of fresh leachate from a municipal solid waste Incineration Plant
Waste Management, 2015Co-Authors: Zhao Liu, Yan Dang, Dezhi SunAbstract:Abstract Fresh leachate from municipal solid waste (MSW) Incineration Plants generally contains extremely high NH 4 + –N concentration which could inhibit the bioactivity of microorganisms. The inhibitory effect of high NH 4 + –N concentration on anaerobic biotreatment of fresh leachate from a MSW Incineration Plant in China has been investigated in this study. The inhibition processes was studied by both static tests and a laboratory-scale expanded granular sludge bed (EGSB) reactor. The specific methanogenic activity (SMA) of the microorganisms in anaerobic granular sludge was inhibited with the NH 4 + –N concentration increasing to 1000 mg/L in static tests. As well the chemical oxygen demand (COD) removal efficiency and the methane yield decreased in the EGSB reactor, while the volatile fatty acids (VFAs) accumulated and extracellular polymeric substances (EPS) of the anaerobic granular sludge increased with NH 4 + –N concentration rising to 1000 mg/L, without any rebounding during 30 days of operation. Decreasing NH 4 + –N concentration to 500 mg/L in influent, the COD removal efficiency recovered to about 85% after 26 days. 1000 mg/L of NH 4 + –N in leachate was suggested to be the inhibition threshold in EGSB reactor. High-throughput sequencing results showed little changes in microbial communities of the sludge for a high NH 4 + –N concentration, indicating that the survival of most microorganisms was not affected under such a condition. It inhibited the bioactivity of the microorganisms, resulting in decrease of the COD removal efficiency.

treatment of fresh leachate with high strength organics and calcium from municipal solid waste Incineration Plant using uasb reactor
Bioresource Technology, 2011Co-Authors: Xiang Cheng, Dezhi SunAbstract:Abstract Treatment of a fresh leachate with high-strength organics and calcium from municipal solid waste (MSW) Incineration Plant by an up-flow anaerobic sludge blanket (UASB) reactor was investigated under mesophilic conditions, emphasizing the influence of organic loading rate (OLR). When the reactor was fed with the raw leachate (COD as high as 70,390–75,480 mg/L) at an OLR of 12.5 kg COD/(m3 d), up to ∼82.4% of COD was removed suggesting the feasibility of UASB process for treating fresh leachates from Incineration Plants. The ratio of volatile solids/total solids (VS/TS) of the anaerobic sludge in the UASB decreased significantly after a long-term operation due to the precipitation of calcium carbonate in the granules. Scanning electron microscopy (SEM) observation shows that Methanosaeta-like species were in abundance, accompanied by a variety of other species. The result was further confirmed by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) and sequencing.
