“…In addition, some of the suggestions are also made, based on conclusions. There are some other review articles and reports (Thong et al, 2012;Gouedard et al, 2012;Fredriksen and Jens, 2013) which seem to have some relevance to the degradation of PZ. However, a vast knowledge has not yet been reviewed in those articles and reports, in form of recent knowledge, pilot plant advancements, degradation kinetics of blends of PZ and structural analogs and formation and decomposition of nitrosamines of PZ.…”

“…The most common amine degradation products are ammonia, formaldehyde and carboxylic acids such as acetic or oxalic one [14,15]. All of them reduce the pH of amine solution and lead to equipment corrosion or technological problems like amine losses or foaming [16].…”

Abstract. Co-firing of biomass with coal for energy production is a well-known technology and plays an important role in the electricity sector. The post-combustion capture integrated with biomass-fired power plants (Bio-CCS) seems to be a new alternative for reducing greenhouse gas emissions. This study refers to the best known and advanced technology for post-combustion CO 2 capture (PCC) based on a chemical absorption in monoethanolamine (MEA). The co-firing of hard coal with four types of biomass was investigated using a laboratory fixed bed reactor system. The comparison of gaseous products emitted from the combustion of coal and different biomass blends were determined using gas chromatography. Research proved that co-firing of biomass in fossil fuel power plants is beneficial for PCC process. It may also reduce the corrosion of CO 2 capture installation. The oxygen concentration in the flue gases from hard coal combustion was comparable with the respective value for a fuel blend of biomass content of 20% w/w. It was also noted that an increase in biomass content in a sample from 20 to 40 % w/w increased the concentration of oxygen in the flue gas streams. However, this concentration should not have a significant impact on the rate of amine oxidative degradation.

“…Wastewater produced from a power plant contains high concentrations of ETA (6,000 ~ 9,000mg/l) and COD (6,000 -13,500 mg/L) [8]. Many investigators have tried various technologies to remove ETA [8]- [11] including biodegradation and AOPs. Hyun, Rhee, Kwon, Kim, and Cha found that mono ETA could be removed by activated sludge [9].…”

Ethanolamine (C 2 H 7 NO, ETA) is used in a power plant to prevent plumbing system from corrosion by maintaining pH at a certain level. Water flowing inside the plumbing system should periodically be cleaned using ion exchange resin. On the way of regeneration of the resin by sulfuric acid, ethanolamine wastewater is produced.Removal mechanism of ETA has not been well established because it is very much resistant material in biodegradability, and even in chemical degradation. In this research high concentration of ETA ranging 5,000 ~ 9,000mg/l was successfully removed closely down to zero level using nano sized zerovalent iron powder (nZVI) and appropriate amount of hydrogen peroxide (H 2 O 2 ). Organic material of high COD concentration (6,000 ~ 13,500mg/l) was also contained in the wastewater along with high concentration of ETA. COD of the wastewater was simultaneously reduced down to 2,500 ~ 6,000mg/l along with ETA when catalytic oxidation of nZVI with hydrogen peroxide takes place, which can be removed further in a biological system of the following process. Removal rate of ETA showed highest at pH 3.Wastewater produced in a power plant containing high concentrations of ETA and COD could be successfully treated up to the level, from which biological process can be applied for direct discharge to the natural water body.Index Terms-Ethanolamine (ETA), hydrogen peroxide (H 2 O 2 ), nZVI (nano Zerovalent iron), nuclear power plant, COD.
