TAILIEUCHUNG - Global Chemicals Outlook Towards Sound Management of Chemicals

Combustion units (process furnaces, steam boilers and gas turbines) give rise to emissions of carbon dioxide, nitrogen oxides, sulphur dioxide and particulates. Nitrogen oxide emissions are most commonly reduced by combustion modifications that reduce temperatures and hence the formation of thermal NOx. The techniques include low NOx burners, flue gas recirculation, and reduced pre-heat. Nitrogen oxides can also be removed after they have formed by reduction to nitrogen using Selective Non Catalytic Reduction (SNCR) or Selective Catalytic Reduction (SCR). Water pollutant control. The main water pollutants from LVOC processes are mixtures of oil / organics, biodegradable organics, recalcitrant organics, volatile organics, heavy metals, acid / alkaline. | UNEP Global Chemicals Outlook Towards Sound Management of Chemicals Synthesis Report for Decision-Makers Copyright United Nations Environment Programme 2012 This publication may be reproduced in whole or in part and in any form for educational or non-profit purposes without special permission from the copyright holder provided acknowledgement of the source is made.
