| The emissions of sulfur dioxide (SO2), nitrogen oxides (NOX), and particulatematter with aerodynamic diameter equal to or less than2.5μm (PM2.5) has lead toserious regional air pollutions, in which haze pollution seems most outstanding. Doingthe research work of the control project for the three pollutants and analyzing thecorresponding cost-effectiveness could offer the reference for the government to makecost-effective control strategies and select the right control path. Regarding the YangtzeRiver Delta region(YRD) as the research area, this research established a databasewhich including the data of energy technologies and end-pipe control technologies frompower plant, transportation, industry and domestic sectors in the region. Based on theoptimaization model-AIM/Enduse, the research discussed the combination project ofenergy technologies and end-pipe control technologies in different control scenarios,considering single air pollutant control and multiple air pollutants control at the sametime. The cost effectiveness of the technology project in different control scenarios isalso analyzed. The research also established a set of development path for energytechnologies and end-pipe control technologies of the four sectors from2010-2030toreach the environmental goal that annual concentration of PM2.5could drop down to35μg/in2030.The results shows that compared with2010, in2030applying more stringentend-pipe control technologies and cost-effective power generation technologies couldreduce PM2.5by70%and NOX/SO2by50%in power sector. In transportation sector, bytightening emission standards the synergistic reduction rate can reach70%. In industrysector, applying more stringent end-pipe control technologies could reduce PM2.5bymore than90%and NOX/SO2by70%. For further emission reductions, energytechnology structures need to be adjusted. Power plant sector need to increase theproportion of wind power generation and IGCC to replace coal-fired plants.Transportation sector need to develop new energy vehicles to replace comventionalvehicles. In industry sector, gas-fired industrial boiler should be further developed toreplace coal-fired indusrial boiler. New dry kiln should replace shaft kiln and rotary kilnmore quickly. In domestic sector, the proportion of electric heater, heat pump heater andelectric cooking and water heater need to be further increased. To reach the environmental goal that annual concentration of PM2.5could dropdown to35μg/in2030, the proportion of conventional coal-fired power generationtechnologies need to decrease from61%to28%. The proportion of advanced coal-firedgeneration technologies need to increase from21%to34%. The proportion of new andclean power generation technologies need to increase from18%to38%. All coal-firedpower plants should be equipped with strict dust removal, desulfurization anddenitrification technologies. Heavy trucks and buses need to implement national Vemission standard in2015and national VI emission standard in2018. Other kinds oftrucks and buses need to implement national V emission standard in2015. Besides,50%of the conventional heavy-duty diesel passenger vehicles should be replaced byheavy-duty CNG passenger vehicles, heavy-duty hybrid electric passenger vehicles andheavy-duty electric passenger vehicles. The proportion gas-fired industrial boiler needto reach75%. The proportation of new dry kiln need to reach78%. At the same time,strict dust removal, desulfurization and denitrification technologies should penetrateinto various sub-sectors of industry sectors. For domestic heating, electric heater, heatpump heater and district heating should offer almost all the service and all the stovesshould be eliminated. For cooking and water heating, electric cooking&water heaterand natural gas stove&water heater need to be further developed. |
