This paper analyzes the situation the main industry in mercury use PVC production. Manufacture of battery, electric light, medical equipment in China. Furthermore, it discusses the details of the best technology the use of mercury emissions reduction and mercury control in that industry. The result is that certain technologies such as low mercury. In PVC industry catalyst, as mercury battery, amalgam substituted Mercury and LED light in the electric light source industry. electronics the thermometer and blood pressure in the medical device industry and so on, reduce mercury able to make full use of and emission reduction in risk mercury pollution to the environment.展开更多

Direct and indirect exergy inputs account for 93.03% and 6.97%,respectively. Compared with coal-fired power generation system before carbon emission reduction,exergy input-output ratio of life cycle "CO2 zero-emission" energy system and exergy efficiency are about 5.563 and 17.97%,respectively,which increases by 62.47% and declines by 11.21% approximately. The model quantifies the energy,resource consumption and pollutant emissions of system life cycle using exergy as the basic physical parameter,which will make the assessment more objective and reasonable.展开更多
