Sulfur Dioxide Emission Combination Prediction Model of China Thermal Power Industry
نویسندگان
چکیده
The prediction of regional sulfur dioxide (SO2) emission of thermal power belongs to gray system which has small amounts of samples and little information, so a appropriate forecasting method is essential. Based on thermal power industry SO2 emission data from state department authorities, considering the main factors of China's thermal power industry SO2 predicted emission, we established a combination prediction model connecting gray prediction model with BP neural network model to predict SO2 emission, and we get more satisfied prediction.

متن کاملSpatiotemporal variations of tropospheric SO2 over China by SCIAMACHY observations during 2004-2009
This paper presents results of measurements of tropospheric sulphur dioxide (SO2) from satellite over China during 2004e2009. SCIAMACHY/ENVISAT SO2 data products have been validated by ground based remote sensing instrument MAXDOAS in China, and with predictions of the atmospheric model GEOSeChem. The spatial and temporal distribution of tropospheric SO2 over China is discussed in this study. T...
متن کاملMitigation of Sulfur Dioxide Emission for Utility Expansion: A Long Term Model Incorporating Independent Power Producers
Efforts to reduce levels of sulfur dioxide (SO2) are increasingly emphasized as an effective response to dire environmental circumstances worldwide. In light of the vast number of environmental uncertainties, a utility must analyze the nexus of different alternatives from a broader and long-term perspective with various implications. While attempting to comply with environmental provisions and ...
متن کاملModeling of sulfur dioxide emissions in Ahvaz City, southwest of Iran during 2013
Sulfur dioxide has two important sources in the atmosphere and this is why most of scientists believe in a geographic split in the globe. Power plants, major emitter of SO2, are located in north hemisphere such as in Russia, China, Canada and the USA. In south hemisphere, phytoplankton produces a massive amount of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS). Then these types of reduced...
متن کاملThe Trend of Sulfur Dioxide Emissions in China after 2000
With the rapid development of the economy, the sulfur dioxide (SO2) emission from China since 2000 is of increasing concern. In this work, we first presented the change of SO2 emission in China since 2000 using a technology-based methodology. Then, we compared the SO2 emission data with a variety of official statistics, ground-based measurements and satellite observations of sulfur related quan...
